- 1. Experiment for large- scale operation of LibreOffice Online, 2019 Edition Masaki Murakami Shinji Enoki librepc@icraft.jp ALMERIA | 13 Sept. 2019
- 2. Agenda ● Who am I ● Intro ● Operation for many users ● Capacity planning ● Configuration ● Load barancing ● Network load balancer ● Needed keys ● Load barancing tools
- 3. Who am I ● Masaki Murakami （村上正記）村上正記） ● ICRAFT Corp. – Main Office:Kobe – Branch:Tokyo,vietnum,mongoria ● Tasks – Server,Network,or IT infrastructure administration – Sales and marketing of “LibrePC” or “LibreBOX” – Management of these tasks members
- 4. Intro ● Last year, I presented the same theme,”Experiment for large-scale operation of LibreOffice Online”. ● About 1 year later, I learned a few things to operate LibreOffice Online, and try to new approach. ● This presentation is the same approach as presented at the LibreOffice Asia Conference.
- 5. It is main
- 6. Operation for many users ● For many users using LibreOffice Online,considering for… – One file editing many users at same time – Many file editing each users ● Infrastructure engineers for non-coding skill… – Reading and editing source code is very hard – Many servers building and load-balancing is suitable for skill of themselves ● It has tried to configure and load balancing for several LibreOffice Online servers.
- 7. Capacity planning ● Capacity planning is important for operating. ● Measurement of Collabora’s document – CPU:1 thread per 10 active user – Memory:10MB per 1 active user – Network bandwidth:100kbps per 1 active user ● Example for 50 active user usually uses – CPU:5 thread – Memory:500MB – Network bandwidth:5Mbps
- 8. Configuration ● Editing “loolwsd.xml” in the installed directory. ● <logging>section – Logfile made at /tmp directory by default. – Recommend is “/var/log/lool”directory with permission – Loglotate weekly ● <ssl>section – Default:/etc/loolwsd – Edit to a directory for Certification placed directory. ● <wopi>section – Add external server calling for LibreOffice Online service ● ex)demo.icraft.jp – <webdav>section
- 9. Load balancing ● It is very important that the service continues to provide. ● Load balancing is usually way to continue to provide service. ● The first step,configuring two LibreOffice Online Servers, and connecting from Nextcloud with Collabora Online Apps.
- 10. Testing environment ● Expecting for… – Editing one file at same server. – LAN Cloud server e.g. Amazon EC2 nextcloud LOOL Server1 LOOL Server2 LB client
- 11. Network load balancer ● I tried to using load balancer,it is sinple function provided by cloud server provider. ● It is fail to load balancing, to access from Nextcloud, 1 file’s access to 2 LibreOffice Online Server. ● Then, I know that I needed the function of an identifiable thing about file, and it is not to use network appliance. – e.g. F5 Big-IP
- 12. Needed keys ● We checked access_log or other Apache logfile to find the key of identifying each files. ● That is hint ssl_access_log ● ● ● ● ● ● ● If we can use the phrase following of “access_token”, and keeping connectivity. 10.x.x.x - - [xx/Sep/2019:yy:mm:dd +0900] "GET /lool/https%3A%2F%2Fdemo.icraft.jp%2Fdemo%2Findex.php %2Fapps%2Frichdocuments%2Fwopi%2Ffiles%2F5205_ocdoknlwsng1%3F access_token%3D3Q6HyMg0HUt3PahrnwOO7SMUdGaAu0Ab%26 access_token_ttl%3D0/ws?WOPISrc=https%3A%2F%2Fdemo.icraft.jp %2Fdemo%2Findex.php%2Fapps%2Frichdocuments%2Fwopi%2Ffiles %2F5205_ocdoknlwsng1&compat=/ws HTTP/1.1" 200 -
- 13. Load barancing tools ● HAProxy can use load barancing for adding custom header and load barancing connections. ● But,old version of HAProxy,at CentOS 7 is not using Regex pattern for adding custom header. ● Next try to use recently version of HAProxy. ● I think that, but we need more ideas and other ways of solution of this problem.
