![Setting Up MySQL (cont.)
• In order to relocate the data directory and binary logs,
we need to modify the configuration file. Before we
can do that, we need to grant permission to do so.
• Open Terminal from Application Launcher > Favorites
• Enter the following commands:
• “su” [switch user command]
• You will be prompted for a password, enter the
admin password
• “chmod –v 777 /etc/my.cnf” [sets permission for
all users to read, write and execute the my.cnf
file
• Minimize Terminal and go to Application Launcher >
Favorites > File Manager
• Double click “Root” in the left menu, then navigate to
‘etc’ and scroll down to “my.cnf” and open with

My sql on linux
- 1. Creating an openSUSE MySQL Server in VMware Ken Wunderle
- 2. Linux Advantages Over Windows • Stability – Linux platforms are inherently more stable than Windows platforms, and usually have less downtime. Additionally, Linux’s open-source architecture allows the community of developers/users to quickly address and patch any known issues quickly • Simplicity – Linux systems use fewer resources and therefore can run on comparatively simpler hardware than a Windows machine. This simplicity also makes Linux servers a bit faster than Windows ones • Affordability – Most Linux distributions are free (or very cheap for enterprise- level)
- 3. Things You Will Need • For this tutorial we will be using: • VMware Workstation 10 • openSUSE 13.2 (download .iso from http://software.opensuse.org/132/en)
- 4. Creating a Linux Virtual Machine • In VM Workstation, create a new virtual machine using the custom configuration and default hardware compatibility settings • For your OS installation, select the directory where your .iso file is located • On the next screen, identify the operating system as “Linux” and select “SUSE Linux 64-bit” from the menu
- 5. Creating a Linux Virtual Machine (cont.) • At this point, you can name your machine whatever you’d like, and then click Next to proceed. • For the following settings, create: • 1 processor with 1 core • 1024 MB of memory • Network address translation (NAT) • LSI Logic controller • SCSI virtual disks • Create new virtual disk > 20 GB > Split into multiple files • Your settings should match the screenshot. Click “Finish” to create the VM
- 6. Creating a Linux Virtual Machine (cont.) • Before you boot up the machine, you will want to add five new hard disks to be configured later as RAID arrays. • To do this, click “Edit virtual machine settings” and then hit the “Add…” button (you may be prompted for your host system’s administrator password. Enter it to continue with the setup.) • From Hardware Type, select “Hard Disk” > Next > select “SCSI” > Next > Create new > Next • Make the disk size 2GB, and split it into multiple files > Next > Finish • Repeat this process until you have 5 new 2GB hard disks in your machine
- 7. Installing openSUSE • Once your VM is configured, click “Power on this virtual machine” • When the machine boots, arrow down to and select “Installation” from the menu • When prompted, select your language and keyboard layout and accept the licensing terms • Do not bother installing Online Repositories or Add-on Products • Accept default partitioning for the file system and set your time zone • Select your GUI. This tutorial will continue with KDE, so perhaps select that if you are a new Linux user and want to follow along with the screenshots
- 8. Installing openSUSE (cont.) • The installation wizard will prompt you to create a root username and password. For simplicity, I have used “admin” for the username and “pass” for the password • Accept default installation settings and click “Install” • After the installation is complete, close the open windows and you’re ready to get started!
- 9. Creating RAID Volumes • We will now create two RAID volumes, a RAID 5 (data striping with parity) and RAID 1 (data mirroring.) The RAID 5, with it’s faster performance, will serve as our data repository. The RAID 1, which has data redundancy, will store our binary logs. • These operations are easily done in the terminal (similar to the Windows command prompt) but we will use the GUI in this tutorial
- 10. Creating RAID Volumes (cont.) • Click the Kickoff Application Launcher in the bottom left of the screen, mouse over to “Computer” and click “YaST” • Inside the YaST window, scroll down in the menu and select “Partitioner”
- 11. Creating RAID Volumes (cont.) • You will see the five hard disks you created in the setup as unpartitioned volumes • Right-click one of these volumes and select “Add partition” > Primary Partition > Maximum Size > Data > Format as XFS > Finish • Repeat this for each of the five volumes • You should have five new partitioned, unallocated volumes when you’re finished
- 12. Creating RAID Volumes (cont.) • Select “RAID” from the menu on the left and click the “Add RAID” button • Select RAID 5, name the array “MySQLdata” and add three of the available volumes to it • Click “Next” through the menus using default selections. In “Mounting Options” mount the partition to “/MySQLdata” and “Finish” to finalize the array • Repeat the process, this time selecting RAID 1, “MySQLbinlog” for the name, adding the remaining two volumes, and mounting to “/MySQLbinlog” • With the two RAID arrays created, click “Next” and “Finish” to finalize the disk partitioning setup
- 13. Installing MySQL • Once the Partitioner has finished applying all changes, you will be back at the main YaST window. From here, we will install MySQL • Select “Software” on the left and “Software Management” in the right- side menu • A great feature of Linux is that the operating systems come preconfigured with a lot of utilities and software packages ready to install, and MySQL is one of them. • Type “mysql” in the input box and click Search to bring up a list of MySQL software and utilities available for installation
- 14. Installing MySQL (cont.) • Frm the available packages, select the following: • mysql-community-server • mysql-community-server-tools • mysql-workbench • If any installation conflicts arise, choose to deinstall mariadb components • Accept any suggested changes and continue through the installation
- 15. Setting Up MySQL • Before we begin using MySQL, we need to do a couple of things: • Move data directory to /MySQLdata (RAID 5) • Enable binary logs and store them in /MySQLbinlog (RAID 1) • Start the MySQL service
- 16. Setting Up MySQL (cont.) • In order to relocate the data directory and binary logs, we need to modify the configuration file. Before we can do that, we need to grant permission to do so. • Open Terminal from Application Launcher > Favorites • Enter the following commands: • “su” [switch user command] • You will be prompted for a password, enter the admin password • “chmod –v 777 /etc/my.cnf” [sets permission for all users to read, write and execute the my.cnf file • Minimize Terminal and go to Application Launcher > Favorites > File Manager • Double click “Root” in the left menu, then navigate to ‘etc’ and scroll down to “my.cnf” and open with KWrite
- 17. Setting Up MySQL (cont.) • Modify the binary log entry by deleting the ‘#’ and changing the location to “/MySQLbinlog/bin- log” • Modify the data directory entry by deleting the ‘#’ and changing the location to “/MySQLdata” • Save your changes to the my.cnf file and close KWrite and the file manager window
- 18. Setting Up MySQL (cont.) • Bring Terminal back up so you can finalize the installation and start using MySQL • Begin the MySQL service by entering in Terminal the command “rcmysql start” • Follow this with “rcmysql status” to show the status of the service, and be sure that it is running • To start the MySQL service every time your Linux machine boots, we’ll modify the boot file. First, grant privileges to the boot.local file in Terminal • You are finished with Terminal, and can close it now • Use the File Manager to get to Root/etc/init.d where you will find the boot.local file. Open it and add the line “/usr/lib/mysql/rcmysql start” after the last # and save the file
- 19. Starting MySQL and Setting Directories • Open Application Launcher > Applications tab > Development > mysql-workbench • When MySQL opens, create a new connection by clicking the + button. Name it whatever you’d like, leave all other settings as default and click OK • Open your new connection to access MySQL
- 20. Starting MySQL and Setting Directories (cont.) • If all is well, you will see the familiar MySQL Workbench window
- 21. Starting MySQL and Setting Directories (cont.) • To move the data directory, click on “Options File” in the left-side menu. When the Options File editor opens, scroll down in the “General” tab until you get to “datadir.” Check the box and type the location of your RAID 5 array (/MySQLdata) • To enable binary logging, click the “Logging” tab and scroll down to “log- bin.” Enable this by checking the box and typing “ON.” Check the “log-bin-index” box and type the location of the bin-log file on the RAID 1 array (/MySQLbinlog/bin-log) • Apply the settings and you’re good to go!
- 22. That’s All For Now • So, now you’ve got a server set up and ready to be populated with data. It’s very insecure at the moment, but applying security features to everything will have to wait for the next tutorial.
