AppSuite:Parallel UISupport OX6 AppSuite RHEL 6 CentOS 6

Add OX6 UI to an OX App Suite Installation

This document outlines the steps required to add an OX6 UI to an OX App Suite installation.

Supported OX Versions

Running parallel UIs (OX6 and OX App Suite) is supported beginning with OX6 version 6.22.2 (backend version 7.0.2) and OX App Suite version 7.0.1.

Requirements

• An OX App Suite installation v7.0.2 or later. This update guide is valid for a system installed through our OX App Suite Download and Installation Guide for RedHat Enterprise Linux 6. It applies also to installations on 100% compatible RHEL clones such as CentOS.
• If you have custom plugins written by yourself which depends on an specific Open-Xchange Server, Open-Xchange can't guarantee that the plugins will work with the parallel setup.
• As for every modification of the installation we strongly recommend that you make a backup of your system(s) before you proceed.

Add Open-Xchange Repository

We start by adding some OX6 frontend repos to our yum repos. Note: the .../RHEL6 repo also is valid for CentOS 6.

# /etc/yum.repos.d/ox.repo
[ox-frontend]
name=Open-Xchange-frontend
baseurl=http://software.open-xchange.com/OX6/6.22/frontend/RHEL6/
gpgkey=http://software.open-xchange.com/oxbuildkey.pub
enabled=1
gpgcheck=1
metadata_expire=0m

Updating repositories and install packages

Install the OX6 frontend packages.

$ yum install open-xchange-gui

This will install the OX6 fronted packages. (OX App Suite frontend package names start with open-xchange-appsuite.)

Configure services

Since we are only adding a frontend, there is nothing to change in the configuration of the backend servers, the database, mail, or such. It is only required to adjust the apache web server configuration in the file /etc/httpd/conf.d/ox.conf.

Basically we need to merge the OX App Suite and OX6 versions of this file. A sample is given in the following.

# /etc/httpd/conf.d/ox.conf
<VirtualHost *:80>
	ServerAdmin webmaster@localhost

	DocumentRoot /var/www/html

        <Directory /var/www/html>

                Order allow,deny
                allow from all
                RedirectMatch ^/$ /appsuite/
        </Directory>
  
        <Directory /var/www/html/appsuite>
                Options None +SymLinksIfOwnerMatch
                AllowOverride Indexes FileInfo
        </Directory>
 
        ErrorLog /var/log/httpd/error.log

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

	        # Strip version
	        RewriteEngine On
	        RewriteRule v=\w+/(.+) $1 [L]
	        # Turn off ETag
	        Header unset ETag
	        FileETag None

	        Header set Cache-Control "no-store, no-cache, must-revalidate, post-check=0, pre-check=0"
	        # Turn off ETag
	        Header unset ETag
	        FileETag None
	</Location>
	
	<Location /ox6/index.html>
	        ExpiresByType text/html "now"
	        ExpiresDefault "now"
	        Header unset Last-Modified
	        Header set Cache-Control "no-store, no-cache, must-revalidate, post-check=0, pre-check=0"
	        # Turn off ETag
	        Header unset ETag
	        FileETag None
	</Location>
</VirtualHost>

Restart the web server:

$ /etc/init.d/httpd restart

That's it. It should now be able to access the OX6 frontend using the location /ox6/ in the request.
