The printable version is no longer supported and may have rendering errors. Please update your browser bookmarks and please use the default browser print function instead.

Update of Open-Xchange Server v6.22 to OX App Suite 7.0 on CentOS 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 Appsuite 7. See Open-Xchange 6.20 to 6.22 Update Guide for CentOS 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 CentOS 6
  • If you have custom packages done by Open-Xchange, please discuss with your Open-Xchange contact when these packages are available for OX Appsuite 7. Do not attempt the update earlier.
  • Custom packages built for 6.22.1 or earlier might not work with OX Appsuite 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 some Appsuite repos to our yum repos. Edit the file /etc/yum.repos.d/ox.repo: 


# adjust this to some final repo location
[appsuite-frontend]
name=Appsuite-frontend
baseurl=http://buildservice.oxoe.int/repos/frontend-release-7.0.1/RHEL6/
gpgkey=http://software.open-xchange.com/oxbuildkey.pub
enabled=1
gpgcheck=1
metadata_expire=0m

# adjust this to some final repo location
[appsuite-backend]
name=Appsuite-backend
baseurl=http://buildservice.oxoe.int/repos/backend-release-7.0.1/RHEL6/
gpgkey=http://software.open-xchange.com/oxbuildkey.pub
enabled=1
gpgcheck=1
metadata_expire=0m

# if you have a valid maintenance subscription, please uncomment the 
# following and add the ldb account data to the urls so that the most recent
# packages get installed
# TODO: insert Update Repo Lines here

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 should still work with this new backend. You should verify this at this moment. Upon the first connection after the backend update, you will ge tthe message Error: updating database, try later. The second try should succeed.

Add the Appsuite GUI

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

It them remains to adjust apache's default.conf as well as proxy_ajp.conf.

Basically you need to merge the OX6 and Appsuite versions of those files. This leaves enough room to screw things up.

For the apache config file /etc/httpd/conf.d/ox.conf, replace the element <Directory /var/www/html> ... </Directory> with the following: 

      <Directory /var/www/html>
              Options Indexes FollowSymLinks MultiViews
              AllowOverride None
              Order allow,deny
              allow from all
              RedirectMatch ^/$ /appsuite/
      </Directory>

      <Directory /var/www/html/appsuite>
              Options None +SymLinksIfOwnerMatch
              AllowOverride Indexes FileInfo
      </Directory>

      ErrorLog ${APACHE_LOG_DIR}/error.log

      # Possible values include: debug, info, notice, warn, error, crit,
      # alert, emerg.
      LogLevel warn

      CustomLog ${APACHE_LOG_DIR}/access.log combined

For the /etc/httpd/conf.d/proxy_ajp.conf, you need to add an element before the element <Proxy /ajax> ... </Proxy>: 

  # OX AppSuite frontend
  <Proxy /appsuite/api>
      ProxyPass balancer://oxcluster/ajax
  </Proxy>

Full sample versions of those files are given in the following.

  1. /etc/apache2/sites-available/default

              Order allow,deny
              allow from all
              RedirectMatch ^/$ /appsuite/
      </Directory>

      <Directory /var/www/html/appsuite>
              Options None +SymLinksIfOwnerMatch
              AllowOverride Indexes FileInfo
      </Directory>

      ErrorLog ${APACHE_LOG_DIR}/error.log

      # Possible values include: debug, info, notice, warn, error, crit,

  2. Please note that the servlet path to the soap API has changed:
<Location /webservices>
    # restrict access to the soap provisioning API
    Order Deny,Allow
    Deny from all
    Allow from 127.0.0.1
    # you might add more ip addresses / networks here
    # Allow from 192.168 10 172.16
</Location>
# the old path is kept for compatibility reasons

<Location /servlet/axis2/services> 

   # restrict access to the soap provisioning API
   Order Deny,Allow
   Deny from all
   Allow from 127.0.0.1
   # you might add more ip addresses / networks here
   # Allow from 192.168 10 172.16

</Location> LoadModule proxy_ajp_module modules/mod_proxy_ajp.so

<IfModule mod_proxy_ajp.c> 

  ProxyRequests Off
  <Proxy balancer://oxcluster>
      Order deny,allow
      Allow from all
      # multiple server setups need to have the hostname inserted instead localhost
      BalancerMember ajp://localhost:8009 timeout=100 smax=0 ttl=60 retry=60 loadfactor=50 route=OX1
      # Enable and maybe add additional hosts running OX here

</IfModule>

After this, stop and start the apache2 and open-xchange services. Then you should be able to use the Appsuite UI. You will again encounter a "Upgrading database, try again later" message on the first login attempt. Later login attempts should work.

Remove the OX6 GUI

This step is optional. You may just skip it and offer both GUIs, the OX6 GUI and the Appsuite GUI.

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 Appsuite GUI 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 Appsuite GUI. To do so, you may consult the Installation Guide for OX Appsuite to learn which sections of the file are required for an Appsuite GUI.

The file /etc/apache2/conf.d/proxy_ajp.conf will not require adjustments; the settings for Appsuite 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.

Finally, there may be backup files created by the package manager during earlier updates. Loook for files with .rpmsave endings or similar in the /opt/open-xchange/etc directory.
