AppSuite:Upgrade from 6.22 for RHEL6

From Open-Xchange
Revision as of 10:45, 14 February 2013 by Dominik.epple (talk | contribs)

Update of Open-Xchange Server v6.22 to OX App Suite 7.0 on RHEL 6.

This example describes updating an OX 6 Server installation to OX App Suite 7.

Supported update path

Updates from an OX6 installation to App Suite are only possible from 6.22 to 7.0. If you have an earlier version of Open-Xchange Server 6 installed, please update to the latest release of v6.22 before attempting an update to OX App Suite 7. See Open-Xchange 6.20 to 6.22 Update Guide for RHEL 6 for instructions regarding that update.

Requirements

  • An Open-Xchange Server installation v6.22.0 or later. This update guide is valid for a system installed through our Download and Installation Guide for RHEL 6
  • If you have custom packages done by Open-Xchange, please discuss with your Open-Xchange contact when these packages are available for OX App Suite 7. Do not attempt the update earlier.
  • Custom packages built for 6.22.1 or earlier might not work with OX App Suite 7.0.
  • As for every update we strongly recommend that you make a backup of your system(s) before you proceed.

Update Open-Xchange Repositories

We start by adding the App Suite repos to our yum repos. Edit the file /etc/yum.repos.d/ox.repo: 


[appsuite-frontend]
name=Appsuite-frontend
baseurl=http://software.open-xchange.com/products/appsuite/stable/appsuiteui/RHEL6/
gpgkey=http://software.open-xchange.com/oxbuildkey.pub
enabled=1
gpgcheck=1
metadata_expire=0m

[appsuite-backend]
name=Appsuite-backend
baseurl=http://software.open-xchange.com/products/appsuite/stable/backend/RHEL6/
gpgkey=http://software.open-xchange.com/oxbuildkey.pub
enabled=1
gpgcheck=1
metadata_expire=0m

Verify the repos: 

# yum repolist

It may be necessary to 

# yum clean all

to make your new repos appear.

Updating repositories and update packages

Download and update all installed packages: 

$ yum update

This will install new config files of some packages as .rpmnew files. Check those files to identlfy files where you want to keep the existing version, put the new version in place, or merge them.

One configuration setting is to be made manually: 

# vi /opt/open-xchange/etc/cluster.properties
com.openexchange.cluster.name=oxcluster

Restart Open-Xchange

To restart Open-Xchange Server after the update, run 

$ /etc/init.d/open-xchange restart

You might want to check with 

$ ps aux | grep open-xchange

that there is exactly one newly spawned process running Open-Xchange Server.

Now the backend has been upgraded to 7.0.x. The v6.22 frontend might still work with this new backend but is *NOT*' supported up to version 6.22.1. The next version 6.22.2 is planned to be fully compatible with the 7.0.2 backend. Upon the first connection after the backend update, you will ge the message Error: updating database, try later. The second try should succeed.

Add the App Suite UI

# yum install open-xchange-appsuite open-xchange-appsuite-backend open-xchange-appsuite-manifest

It them remains to adjust Apache's ox.conf as well as proxy_ajp.conf. Full sample versions of those files are given in the following. 

# /etc/httpd/conf.d/ox.conf

</IfModule>

After this, stop and start the httpd and open-xchange services. Then you should be able to use the App Suite UI.

Remove the OX6 GUI

This step is optional. You may just skip it and offer both GUIs, the OX6 GUI and the App Suite UI. This will only be supported after the 6.22.2 release!

If you want to uninstall the OX6 GUI, this step consists of removing the OX6 GUI packages and and adjusting Apache's configuration.

The packages to be removed can be identified by their version number in the output of rpm -qa | grep open-x. It will probably boil down to uninstall everything which starts with open-xchange-gui, as the names of the App Suite UI packages start with open-xchange-appsuite. 

# yum remove open-xchange-gui*

Then adjust the /etc/httpd/conf.d/ox.conf file to remove obsolete stuff which was required for the OX6 GUI, but is not required by the App Suite. To do so, you may consult the Installation Guide for OX Appsuite to learn which sections of the file are required for an App Suite UI.

The file /etc/httpd/conf.d/proxy_ajp.conf will not require adjustments; the settings for App Suite are a superset of the settings of the OX6 GUI.

Leftover configuration files and runtime data

After the update you may see leftover configuration files and runtime data below /opt/open-xchange/etc It is safe to remove all files ending in .rpmsave or .rpmnew once you are confident that your configuration is working after the update.
