Introduction
In this document I will walk you through the necessary steps to
perform a ground-up installation of 64-bit CentOS 7, the minimal
configuration of the Operating System, configuration specific for
IBM/HCL Domino installation, and finally the installation of 64 bit
IBM/HCL Domino 10.0.1.
This document and (any future accompanying videos) are aimed at
administrators who have some working knowledge / understanding
of IBM/HCL Domino, but who may be unfamiliar or uncomfortable
with Linux. The goal of this document is to demonstrate the very
minimal requirements for Domino on Linux, point out some
potential pitfalls, and ultimately show that installing and running
Domino on a Linux machine is much easier than you think.
COPY / PASTE
If you are sitting at a server console with this document in electronic format,
then do yourself a favor whenever you see a console command such as:
># cat /etc/selinux/config
Copy / paste it directly into the console. It will save you a bunch of time.
Just make sure to change any specific-to-your-installation values before
hitting that enter key.

Note on Fonts and Spacing
I am deliberately using larger fonts because they are easier for me to read.
I realize they may appear gigantic on lower resolution displays, and for that
I'm sorry for you.
Typographic Conventions
Throughout this document there are several different “types” of text.
• There is explanatory text, which appears in Arial.
• Example file content or lists of information appear in Consolas.
• Courier New is used for command-line content (stuff you
should type).
• Console commands are orange bold Courier New.
• I use colors, italics, and bold fonts in various areas to help stuff
stand out. You are a smart person, you will figure it out.
I am a bit of an old-school type of person, in that I prefer paper documents
to digital. I find being able to scrawl hand-written notes onto a document
comforting. This document is intended to be printed out and used /
referenced many times. To that end, I have made sure to include lots of
blank white space on this document for you to take your own notes. If that
doesn’t suit you then just scroll on by.
"Linux" is a registered trademark of Linus Torvalds. “CentOS” is a registered trademark of the CentOS Project. “IBM”, “Domino”, and “Domino
10.0.1” are registered trademarks of International Business Machines, Incorporated. All other trademarks are property of their respective owners.
As of this writing, the HCL purchase of the IBM Collaboration software portfolio has not been finalized, which is why I refer to it as “IBM” Domino
and not “HCL” Domino; although I am totally stoked about the purchase. I think HCL will be able to improve certain aspects of the portfolio that,
for whatever reasons, IBM was unable to do. All other content is Copyright @ 2019 by Devin S. Olson unless otherwise assigned. This document

should probably move on to the more important stuff contained in the rest of this document. Seriously, there is nothing else important enough in this
paragraph worth reading.

CentOS Installation
Depending upon your installation, you might be setting up a hosted server
with one of the various hosting providers (such as prominic*), a Virtual
Machine, or directly as the main Operating System on a physical server.
Each of these installation types have their own unique nuances for the
installation. I am going to focus on the major points that all of these have in
common. Most of the major hosting providers will handle the base
Operating System and Network IP configuration automatically. If this fits
your situation, just go ahead and skip to the next section, User Account and
SSH Configuration.
For the purposes of preparing this document, I performed a Virtual Machine
installation using Oracle VirtualBox running in a Windows 10 environment,
and used CentOS-7-x86_64-Minimal-1801.iso
This is a totally uncompensated plug for the wonderful folks over at prominic (https://prominic.net); in fact, I didn’t even bother to get their
permission before mentioning them in this document. I have received nothing for this. The reason I’m plugging their company is simple: I have
known John (and by proxy Justin) professionally for nearly 20 years. When a business stays focused on core values and takes care of their customers
for that long it says something. To me that something is best summed up in a single word: integrity. They have a great and dedicated team over
there. If you are looking for a hosting provider, I suggest you give them a call.

[Optional] Create Virtual Machine
• Type = Linux
• Version = Red Hat (64 bit)
• RAM = 2 Gig
• Image Type = VDI (Virtual Disk Image)
• Image Footprint = Dynamically Allocated
• Image Size = 32 Gig
• Optical Disk Drive pointing CentOS iso
• Enable Network Adapter 1 attached to NAT
• Enable Network Adapter 2 attached to Host-only Adapter
• Verify different MAC addresses (Advanced settings)

Install 64-bit CentOS 7 Minimal
The Minimal installation version is all that is needed. Latest versions
available at www.centos.org.
During the installation you will need to answer various things like language
and keyboard layout, installation destination, how to configure the partitions,
the root password, time zone, and whether or not to configure a user
account. Do not create an additional user at this time.
Partitions
Your partition scheme is entirely up to you, and a full discussion of partition
layout is beyond the scope of this document. However, in order to make
things fairly easy (and remembering that I’m only using a 32 G total disk
size and modern SSDs make a lot of the old partitioning schemes
irrelevant), I do have a few recommendations.
Dedicated DAOS and Index Partitions
If you have multiple physical drives, then I recommend creating a DAOS
partition on another drive, and an index partition on SSD. Creating
dedicated partitions for DAOS or index content on the same drive (be it
platter or SSD) is pointless -they need to be different physical devices. If
you are using RAID, then use a different controller as well.
Regarding XFS vs ext4
Red Hat and CentOS are both pushing the new XFS File system because it
is super awesome. However, it is a PIA to resize, and for a Domino server
ext4 is just fine. I don’t see any real benefit from going to XFS at this time.
Partition Size Device Type
& File System
Volume
Group
Notes
swap 4 Gig Standard swap NA For memory up to 4 Gig, a swap partition of 2x
the memory is recommended. 4 – 8 Gig should
be 1.5x memory, and 8 – 32 Gig should be 1x
memory, with a max of 32 Gig. (I know the math
doesn’t work out)

boot 1 Gig Standard ext4 NA A full Gig here might seem super wasteful, but
have you ever had to resize a boot partition? It
is a GIGANTIC hassle. Just go ahead and give
yourself some extra space now while it is easy to
do.
/home 2 Gig LVM ext4 vg00 Only 2 Gig for /home? Remember, this is a
Domino server we are setting up. Anything
more than this is unnecessary.
/ 4 Gig LVM ext4 vg00 Other than /home and /domino, I am leaving
everything else (/tmp, /var/, /etc) here in the root
partition. If you are planning on using your
server for anything else than a Domino server,
you might want to consider adding additional
explicit partitions; but I really don’t see a need to
do so. Bear in mind this setup is for minimal
installation. If you have enough disk space, I
suggest you make this at least 8 Gig.
/domino 21 Gig LVM ext4 vg00 I used all remaining space for the dedicated
/domino partition. Only you know what your size
needs are going to be. Once again, this is for a
minimum functional installation.

Root password
Create a proper strong password. Something that is easy for you, a human,
to remember; and hard for a machine to guess. Don’t fall for that crap being
pushed by idiots saying to use passwords like “37K@D}sk&w”; that is a crap
password because you can’t remember it and it is not hard for a machine to
guess. Use something like “LoveTotallyAwesomeDomino” or
“SpankyBeerIsTheBestInTheWorld”. Go ahead and throw in a few salted
characters replace “e” with “7” and “o” with “@” if it makes you feel better.
Long passwords are strong passwords. Now, once you have created
your password, WRITE IT DOWN and store it someplace safe. I know that
will probably irritate some security professionals, but lost passwords are
useless.

Reboot the server after the Operating System is installed and sign in as
root, using the easy-to-remember password you have created.

[OPTIONAL] Configure network
I don’t intend for this document to become a dissertation on networking,
protocols, DNS, or IPV4 vs IPV6. To that end I’m going to keep this as
simple as possible and focus entirely on IPV4. There is a big wide world of
information, written by people much smarter than me, available out there on
the web. Take some time to read some of it (packet-switching can be
weirdly interesting).
Check the network cards and their status
># nmcli d
This example shows the loopback device (lo), and two network cards
(enp0s3 and enp0s8).
There are two primary ways to configure your network cards in CentOS 7.
You can use either the network manager utility (nmtui), or, if you are more
comfortable, simply directly edit the appropriate configuration files. It really
doesn’t matter which one you choose, they both accomplish the same thing.

Network Manager Utility
Using the network manager utility is fairly straightforward. You pick the
various tasks, make the edits as needed, then save and quit. It does take a
bit of patience, as interface navigation is not the best, but it works. If you
would prefer to go old school (like me) and directly edit the configuration
files, then skip ahead to the next section. Otherwise, fire up the utility.
># nmtui
Device enp0s3 using DHCP

Directly Edit Configuration Files
This is the method I prefer, simply because it is faster (and easier to check
all settings) for me. Use whichever method you prefer.
You can use the network information from the previous command, or you
can use the ip command.
># ip a
While this provides more information than the nmcli command, it is not
nearly as simple and clean an output.
The configuration files which need to be edited can be found in the
/etc/sysconfig/network-scripts folder. The naming pattern is ifcfg-
DEVICENAME, where DEVICENAME is the name of the device.
I prefer the vi editor. If you prefer another editor, you are wrong. The only
editor worth using is vi. All others are imposters to the benevolence and
glory that is vi.
># vi /etc/sysconfig/network-scripts/ifcfg-DEVICENAME
*i <return> to insert text
<esc> to finish inserting text
*:wq <return> to save and quit

I have noted the necessary changes in bold green, and comments in CCP
(Consolas Carrot Poop).
DHCP Example
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp # Use DHCP to assign the IP
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPVC6NIT=no # Do not initialize IPV6
IPVC6_AUTOCONF=no # Do not auto configure IPV6
IPVC6_DEFROUTE=no # IPV6 should not be the default route
IPVC6_FAILURE_FATAL=no # Ignore IPV6 Failures
NAME=enp0s3
UUID=the universally unique id of your device # Do not change
DEVICE=enp0s3
ONBOOT=yes # Enable interface when booting

Static Example
The IP address, netmask, and gateway for the example below are from the
VM instance I am using for writing this document, and are unlikely to work in
your environment. You can get the correct values from your VM hosting
OS. If you are using VirtualBox on Windows, you can get this information
from the command prompt:
C:UsersYou> ipconfig
Look for VirtualBox Host-Only
Network. Use the IPv4 Address
for your GATEWAY, and the
Subnet Mask for your NETMASK.
Assign any IPADDR you wish (as
long as it is valid for the Mask) and
you should be good to go.
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static # Assign a Static IP address
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPVC6NIT=no # Do not initialize IPV6
IPVC6_AUTOCONF=no # Do not auto configure IPV6
IPVC6_DEFROUTE=no # IPV6 should not be the default route
IPVC6_FAILURE_FATAL=no # Ignore IPV6 Failures
NAME=enp0s8
UUID=the universally unique id of your device # Do not change
DEVICE=enp0s8
ONBOOT=yes # Enable interface when booting
IPADDR=192.168.56.45 # IP address
NETMASK=255.255.255.0 # Subnet Mask
GATEWAY=192.168.56.1 # Default Gateway

Verify Changes and Restart Network
Save your changes and exit back to the command prompt. You can verify
your changes by displaying the contents of the config files (where
DEVICENAME is the name listed from the previous nmtui command).
># cat /etc/sysconfig/network-scripts/ifcfg-DEVICENAME
Use systemctl to restart the network:
># systemctl restart network
You can also use systemctl command to check the status of the network:
># systemctl status network

SSH (Secure Shell) - Part 1
SSH Clients
If you are using a Mac or Linux to perform this configuration, the SSH
command is included as part of the operating system, because real
computers have this. Microsoft finally decided to include this standard
command with the release of Windows 10. If you are using a previous
version of Windows, you should probably bang your head against the desk
in frustration. Assuming you cannot upgrade, you will need to install a 3rd
party SSH client in order to proceed. I recommend Putty (available at
https://www.putty.org ), as it is a simple and easy to use tool that JFW. (If
you don’t know what JFW means you obviously have never been to one of
my sessions. https://www.urbandictionary.com/define.php?term=JFW )
SSH on Windows 10
I have noticed some quirky behavior
with the SSH command on Windows
10, specifically when starting an
editor in the client. The command
window font color will sometimes
change, making it nearly unusable.
Fortunately, this is easy to change.
Right-click on the top bar of the window and
select Properties.
In the displayed Properties dialog, select
the Colors tab, then specify the color
combination you want and click the OK
button.

Once you have done that the
window color will change to the
colors you specified.
SSH and CentOS7
The CentOS 7 Minimal installation includes the SSHD service and initial
configuration information; which makes things much easier than with
previous distributions. There is no need to manually install SSH. There is,
however, some configuration that we need to do. Ironically, this all starts
with opening an SSH session to your server by issuing the following
command:
C:UsersYou> ssh root@your.server.host.ipaddress.or.fqdn
Enter the root password log in and proceed.

User Accounts
Without going into too much unnecessary detail, all Linux user accounts
require a minimum of two things: a username, and a primary group with
which the user account is associated. Your Domino server will need to run
using a Linux account, which means you need to decide upon a group
name and a user name for your Domino server. This can be as simple as
“servergroup” and “server”, or (if you follow IBM’s documentation), “Notes”
and “Notes”. I suggest using your primary organization name for the group,
and the server name for the user. This makes it easy to keep track of when
setting up multiple servers for an organization. For the rest of this
document I will refer to these as groupname and username.
NEVER run Domino AS root
Create the user account for your Domino server as follows:
Create a Group
># groupadd groupname
Add the user
Use the useradd command to add the user. I know the spacing in the
example is weird, but it works.
-g initial group to which the user should be added
-s shell for the user when signing in. User scripts are here.
-d home directory
-m make the user
># useradd -ggroupname -s/bin/bash -d/home/username -m username
Create a password for the user
># passwd username

SSH (Secure Shell) - Part 2
Now that you have added a user account, it is time to configure the SSH
daemon to provide a bit more security for your server. As with many other
topics in this document, there is massive amount of information and context
available that I’m not going to go into. What follows is the absolute bare
minimum SSH configuration changes you should make.
Configure and verify SSH
Edit the sshd_config file using the greatest editor in the universe
># vi /etc/ssh/sshd_config
*/ searchtext <return> to search for text
Find the line #PermitRootLogin yes and change it to no, add additional
settings for AllowUsers and AllowGroups, then save and close the file:
PermitRootLogin no
AllowUsers username
AllowGroups groupname
Use systemctl to restart the SSHD daemon:
># systemctl restart sshd

Start another SSH Session
This is very important, and I cannot stress it enough: DO NOT CLOSE
YOUR CURRENT SSH SESSION. If you have mis-configured the sever
you will not be able to get back in to correct things. So, to be clear, attempt
to start a NEW SSH Session for root, and enter your password This should
fail.
C:UsersYou> ssh root@your.server.host.ipaddress.or.fqdn
Assuming your login attempt fails (hooray for fail fast, fail early testing), now
attempt to start an SSH session using the user credentials you created.
C:UsersYou> ssh username@your.server.host.ipaddress.or.fqdn
Once you have successfully logged in, use the su command and then enter
the root password to change to the root user.
># su
If you cannot login using the new SSH Session, use the first window root
session to make the necessary corrections until you can open a new
session.

Install Required Packages
The following packages are required for Domino 10 on CentOS. Use the
yum command to install them.
• ntp: network time protocol service
• perl: open source general-use interpreted scripting language
• bc: an arbitrary precision numeric processing language
># yum -y install ntp perl bc
Start and enable the cron service
># systemctl start crond
># systemctl enable crond
># systemctl status crond
Turn off and disable SELinux
Security Enhanced Linux (SELinux) is enabled by default on CentOS 7, and
is incompatible with Domino. It needs to be disabled.
># vi /etc/selinux/config
Change the setting to SELINUX=disabled and save and close the file. Then set
SELINUX enforcing mode to disabled.
># setenforce 0
Enable and activate the time service
The Network Time Protocol service needs to be enabled.
># ntpdate pool.ntp.org
># systemctl start ntpd
># systemctl enable ntpd
># systemctl status ntpd

Firewall Configuration
NOTE: THIS IS THE MINIMAL configuration. A complete set of firewall
rules must be configured if your server will be publicly accessible -
and is beyond the scope of this document. DO NOT RELY solely on
this configuration.
Centos 7 comes, by default, configured to use FirewallD for firewall security
and management. FirewallD is dynamically managed firewall with support
for network / firewall zones that define the trust level of network connections
or interfaces. There is a very nice write-up at linode community for
configuring FirewallD on CentOS.
That being said, I hate FirewallD for servers. Most of the enhanced
security features, zones, and services available with FirewallD are more
suited for a desktop / workspace environment, and I’m not willing to put up
with the massive headaches that come with dealing with FirewallD.
I prefer iptables; what follows are instructions for replacing FirewallD with
iptables.
Install iptables
># yum -y install iptables-services
Ensure the ports required by the Domino server are open
Common Ports (for reference, only open the ports you will use)
• 20 FTP (File Transfer Protocol transfer)
• 21 FTPC (File Transfer Protocol Command)
• 22 SSH (Secure SHell)
• 389 LDAP (Lightweight Directory Access Protocol)
• 636 LDAPS (Lightweight Directory Access Protocol over SSL)
• 1352 NRPC (IBM Notes/Domino RPC)
• 80 HTTP (Hypertext Transfer Protocol)
• 443 HTTPS (Hypertext Transfer Protocol over SSL)
• 25 SMTP (Simple Mail Transfer Protocol

• 143 IMAP (Internet Message Access Protocol) -only if you will have
IMAP mail clients
• 220 IMAPV3 (Internet Message Access Protocol Version 3) -only if you
will have IMAP mail clients
• 993 IMAPS (Internet Message Access Protocol over SSL) -only if you
will have IMAP mail clients
• 110 POP3 (Post Office Protocol Version 3) - only if you will have
POP3 mail clients
• 995 POP3S (Post Office Protocol Version 3 over SSL) - only if you
will have POP3 mail clients
• 8585 Used by Domino Remote Server Setup
In the previous version of this guide I recommended installing and using
Webmin. I have since changed my mind. If you want to use Webmin go
ahead and follow the instructions found in that document. If you just want to
get up and running as quickly as possible, then just manually configure the
firewall.
Edit iptables using vi
># vi /etc/sysconfig/iptables
Find the lines
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
Change default INPUT / FORWARD policies from ACCEPT to DROP
:INPUT DROP [0:0]
:FORWARD DROP [0:0]
Find the line:
-A INPUT -j REJECT --reject-with icmp-host-prohibited
The lines immediately prior to this line identify the ports which are to be
opened in the firewall. It is best to keep everything closed and only open
the specific ports that you want opened. There is by default an entry to open
port 22 (the SSH protocol). Make sure that you keep port 22 open (either

by leaving the line in place or by using the line in the following content),
otherwise you will effectively lock yourself out of your server. The SSHD
service can run and listen forever, but if you close the port you will never get
back in. Consider yourself fairly warned.
The following content can be cut and pasted into your vi editor (after hitting
“i” to enable insert mode). The green lines beginning with hashtags are
comment lines to identify the protocol that each subsequent line is
specifying to open in the firewall. If you don’t want a particular protocol,
then do not add it. You might already have a line for SSH, you can leave
that there.
# SSH
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
# LDAP
# LDAPS
# NRPC
# HTTP
# HTTPS
# SMTP
# Domino Remote Server Setup
If you want to only allow SSH from a specific IP address, change the SSH
line to:
-A INPUT -s your.allowed.ip.address/24 -m state --state NEW -p tcp
--dport 22 -j A
If you want to allow Webmin clients to access, you will need to open a port:
# WEBMIN

Save and close the file. You can use the cat command to verify your
changes:
># cat /etc/sysconfig/iptables
You now have a choice to make. If you are going to be using IPv6
addressing, then you will need to similar changes as you made to the
iptables file. If you don’t want to use IPv6 then you will need to disable
IPv6. You can either edit your systemctl configuration, sshd configuration,
and various other configuration files to ensure that IPv6 is properly disabled
(and your server still works without getting all wonky), or you can just use
your ip6tables firewall configuration to close all the IPv6 ports.
Edit ip6tables using vi
># vi /etc/sysconfig/ip6tables
What follows is the default ip6tables file with my changes applied in bold
green. Apply the changes to your file.
# sample configuration for ip6tables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default
configuration
*filter
:INPUT DROP [0:0]
:FORWARD DROP [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j DROP
-A INPUT -p ipv6-icmp -j DROP
-A INPUT -i lo -j DROP
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j DROP
-A INPUT -d fe80::/64 -p udp -m udp --dport 546 -m state --state NEW -j DROP
-A INPUT -j REJECT --reject-with icmp6-adm-prohibited
-A FORWARD -j REJECT --reject-with icmp6-adm-prohibited
COMMIT
Test your changes
># sh -c ‘iptables-restore -t < /etc/sysconfig/iptables’

># sh -c ‘ip6tables-restore -t < /etc/sysconfig/ip6tables’
If you have entered everything correctly, then you will get absolutely zero
response when entering the sh commands. That is a good thing.
Shut down FirewallD and Start iptables
Enter the following as one single command:
># systemctl stop firewalld && systemctl start iptables;
systemctl start ip6tables
Verify iptables and ip6tables
># iptables -S
># ip6tables -S
SSH from another console
While this might seem a bit redundant, this is where you want to be
absolutely certain you can get back into your server. Open another console
window and try to ssh to your server.
C:UsersYou> ssh username@your.server.host.ipaddress.or.fqdn
If you are unable to login then you need to go back and correct something.
Otherwise we can proceed to remove FirewallD from the system.
Disable FirewallD and Enable iptables
># systemctl disable firewalld
># systemctl mask firewalld
># systemctl enable iptables
># systemctl enable ip6tables
># systemctl status iptables
># systemctl status ip6tables
The status commands should give a response similar to the following. If
you see “Active: active (exited) since ….” that means everything is working
normally. (Yes, I realize it can be confusing).

[OPTIONAL] Set the Host Name of your server
># hostnamectl set-hostname fully.qualified.host.name
A reboot is required to properly apply the hostname. Issue the following
command, wait a few minutes, and the log back in via SSH.
># reboot now
Make sure everything is up to date.
Use yum to update installed content.
># yum -y update

Domino Specific Configuration
Disable Conflicting Services
There are three specific services that conflict with Domino. Depending upon
the version of CentOS these may have been automatically installed. They
need to be disabled and removed. These services are httpd, sendmail, and
postfix. Follow the subsequent instructions for each of these services.
Check the status of the service
># systemctl status servicename
If the service is operational you will need to kill it.
># systemctl stop servicename
Then disable and remove the service.
># systemctl disable servicename
># systemctl mask servicename
Set File Handles
Increase the number of file handles available for use.
># ulimit -n 65535
># vi /etc/security/limits.conf
Add the following lines to the end of the file, where username is the name
of user you created for running Domino:
username soft nofile 65535
username hard nofile 65535

Reboot the server
You need to reboot the server at this point.
># reboot now
Log in via SSH
After the server has rebooted, log in again via SSH and change to
Super User (root)
># su (enter password when prompted)
Allow Domino to tune the Linux kernel
Use the export command to set the operating system variable.
># export DOMINO_LINUX_SET_PARMS=1
Use either vi or the echo command to add the export command to the end
of the /home/notes/.bashrc file:
># vi /home/username/.bashrc
Add the above export command to the end of the file and save it.
-- OR –
># echo -e "nexport DOMINO_LINUX_SET_PARMS=1" >>
/home/username/.bashrc
Create the directory for your Domino server
You need to decide where to put your Domino Data. If you followed my
suggestion when setting up the partitions for your server this will be very
easy.
># mkdir /domino/servername/dominodata -p

Verify the directory exists and make note of this directory, you will need it
during installation.
># cd /directory path you just created
Get Install File
Now you need to get the Domino installation file onto your newly created
server so you can install it. There are a number of ways to do this, I
strongly recommend you use SCP (Secure Copy Protocol). If you are
using Linux, Mac OSX, or Windows 10 this command is built into the OS. If
you are using a previous version of Windows, you will need to download
and install an SCP Tool. I recommend WinSCP.
Use either WinSCP or command line to upload your Domino Installation
media to your new server (place it in your server user’s home directory for
now).
If using command line, change directory to the directory containing your
installation media and use the SCP command to upload it to your server.
C:UsersYou> scp DOM_SVR_V10.0.1_64_BIT_Lnx.tar
username@your.server.host.ipaddress.or.fqdn:~
Do not forget the colon tilde (:~) at the end. That tells the SCP command to
place the file in the home folder of the user.

Go back to your server console, switch to your user’s directory, and verify
the file is there
># cd /home/username
># ls -l
Verify File and Unpack
Use the tar command to check the file.
-t Table of contents. List all the files contained in the tar file.
-v Verbose output.
-f Use the filename from the argument parameters.
-x Extract or restore the file(s)
># tar -tvf DOM_SVR_V10.0.1_64_BIT_Lnx.tar
If there are problems with the file, you will need to delete it and download a
clean one. If there are no problems, then go ahead and extract the file
contents.
># tar -xvf DOM_SVR_V10.0.1_64_BIT_Lnx.tar
Take a few minutes and go stretch. The server is now ready for installation; you
have done a lot of work and deserve a break. You might want to get yourself a tasty
beverage or a light snack; or perhaps have a conversation with another human for a
few minutes before continuing.

Domino Installation
Find and run the installation
Use the ls command (without the -l argument) to list the directory contents,
then navigate down through the folders using the ls and cd command as
needed until you see the install file displayed, then run the file:
># ./install
Follow Prompts
Answer the questions as follows (pressing <enter> will accept the bracketed choice):
• Do you want to continue installation in console mode? [Yes]
• Welcome to the InstallShield Wizard. [1]
• Read and agree to the license agreement. [1]

Change Directory Ownership
Use the cd command to change to the domino directory and then change
ownership of the server’s directory to the username for the server.
>$ cd /domino
>$ ls -l
>$ chown -R username:groupname username
>$ ls -l
Congratulations. The server is now installed. Now we just need to get it
configured and operational.

Domino Setup
Switch ID
Change back to the user id you used to log into the SSH session:
># exit
Server ID
If this is the first server in your organization, go ahead and skip to the next
step. Otherwise you have a bit of administrative work to do. Use your
domino administrator to create a new server id file. Once you have the file,
you need to put it on your new server. Use SCP in the same manner as the
installation files to place the file into your server’s home directory. Then use
the mv command from the console to move the file from the home directory
to the domino directory.
>$ cd ~
>$ pwd
>$ ls -l
># mv server.id /domino/servername/dominodata
>$ ls -l

Launch Server in listen mode
Change to the /domino/servername/dominodata folder:
>$ cd /domino/servername/dominodata
Launch the server and put it into listen mode for remote server setup
access:
>$ /opt/ibm/domino/bin/server -listen
Domino Remote Server Setup Utility
On another Machine, start the Domino Remote Server Setup Utility Client.
Enter the ip address of your server in the dialog box, and follow the prompts
to configure your server. I’m not going to walk you through this, it is very
straight-forward, and you have probably already done it dozens of times
anyway.
When you finish the configuration, a dialog will ask you if you want to shut
down the listening server. Do so, then go back to the SSH console from
which you launched the server. It should be back to a command prompt.

Launch Domino
Launch the server, only this time do not add any parameters.
>$ /opt/ibm/domino/bin/server
Celebrate
Congratulations. Your server is now operational. A
quick and simple test to verify is to type in the server's
ip address in s browser URL window. You should see
the new IBM Domino Start Page. Throw your feet up
on the desk, pop open a bottle of your favorite beverage
(I suggest anything from Spanky's Brewery), and call it
a day.
You have done well padawan.

APPENDIX A - STICKY BITS
The Sticky bit problem that has plagued Domino since R7 (7.0.3 specifically)
seems to finally have been resolved with the release of version 10; which
means this appendix is no longer needed. I have, however, decided to keep
it intact. If you run into any weird bindsock issues with your Domino server I
suggest you try these instructions first.
Set Sticky bit on Bindsock
When your Domino Server attempts to start any service that needs to bind
to a socket (port); it does so by invoking the bindsock program. There is
a problem with the installation / setup of IBM Domino Server, in that it does
not set the sticky-bit on the bindsock program file. In a Linux environment,
a sticky-bit causes an executable file to be run using the credentials of the
file owner instead of the invoking user. The proper term for this is Set User
Identification Attribute, but everybody just calls it sticky-bit. The bindsock
program must be run using the root user's credentials, and therefore must
have this sticky-bit set.
If you attempt to start your Domino server immediately after you finish
configuring it using the remote server setup you will discover that your
HTTP server cannot start, because it cannot bind to port 80. Fortunately,
the solution to this is very simple. From the console, change to the Super
User and enter the password:
># su (enter password when prompted)
Change to the domino server program “root” directory:
># cd /opt/ibm/domino

Use the find command to search for the bindsock program file.
># find -name 'bindsock'
./notes/90000/linux/bindsock
Change to the directory containing the file:
># cd notes/90000/linux
Now use the ls -l command to display the information about bindsock:
># ls -l bindsock
-r-sr-xr-x 1 root bin 9880 Mar 9 02:41 bindsock
This indicates that this bindsock file is owned by the root user, and the bin
group. The block of text at the beginning (-r-sr-xr-x) indicates the type
and permissions for the entry. The very first character “-” indicates the type
of entry, in this case a normal file. There are several other possible
characters with different meanings, such as “d” for directory, or “b” for block
device, but for now all we care about is the “-”.
What follows after this first character are three sub-blocks of three
characters each. Each sub-block defines which specific permissions are
enabled for the entry, and the position of the sub-block defines for whom
the permissions are to be applied. The first sub-block is for the owner of
the entry, the second for the group, and the third for everybody else. There
are three standard permissions: read, write, and execute. We can interpret
the result of the ls-l command as follows:
-r-sr-xr-x 1 root bin 9880 Mar 9 02:41 bindsock
The first block “r-s” tells us that the owner of the entry (in this case root) is
allowed to read the entry, is not allowed to write to the entry (no “w”), and
can execute the entry using the owner's id (the “s” denotes that Set User
Identification Attribute is in force). Normal executable files just have this set
as “x”.

The second block “r-x” tells us that the group for the entry (in this case bin)
can read the entry, is not allowed to write to the entry (no “w”), and may
execute the entry.
The third block “r-x” tells us that everybody else (users who are neither the
owner of the file nor a member of the group) can read the entry, cannot
write to the entry (again, no “w”), and may execute the entry.
These settings are entirely appropriate for most executable files. In this
case however they are not correct, because the bindsock program makes
changes to system resources (ports) that for security reasons are only
allowed to be made by the root user. This is why the HTTP (and possibly
LDAP, IMAP, SMTP, etc.) service is failing to start. To correct the problem,
we need to add the stick-bit to bindsock. This is accomplished using the
chmod utility, followed by an ls-l to verify our changes: ist it again to verify
># chmod +s bindsock
># ls -l bindsock
-r-sr-sr-x 1 root bin 9880 Mar 9 02:41 bindsock
This change will now cause all users who are neither the root user, nor
members of the bin group, to execute the bindsock using the root user's
credentials. Which means our Domino services can now be properly bound
to a socket when starting up.

APPENDIX B - ADDITIONAL RESOURCES
There is a lot more configuration you need to do to make your server
production ready. Do the appropriate research, read the appropriate blogs,
etc.
'nixCraft has a great article about iptables configuration.
https://www.cyberciti.biz/tips/linux-iptables-examples.html
One incredibly useful resource is Daniel Nashed's blog and his wonderful
Domino on Unix/Linux Start Script.
https://www.nashcom.de/nshweb/pages/startscript.htm
I cannot imagine running a Production level Domino server without Daniel’s
script. This is an absolute must-have. If you happen to run into him
anywhere, take the time to thank him for his hard work.
Bill Malchisky’s blog is a great resource for Linux / Domino content.
http://www.billmal.com/billmal/billmal.nsf
If you are interested in the thoughts and opinions of the person whom I
personally consider to be the very best Domino Administrator on the planet,
then check out Turtle Partnership’s blog:
https://turtleblog.info
If you are looking for a hosting provider, I recommend:
• DigitalOcean: https://www.digitalocean.com – simple hosting
• Prominic: https://prominic.net – Domino Hosting Experts
To be clear, I have received no compensation (or even permission) from these
individuals. I mention them because I believe them to be absolute experts at what they
do, and I trust their professional advice and judgement.
