AppSuite:Parallel UISupport OX6 AppSuite RHEL 6 CentOS 6

From Open-Xchange

TODO:

  • verify the version numbers: 6.22.2 for OX6 and 7.0.2 of OX App Suite
  • Add some disclaimer that plugins require dedicated versions for OX6 and App Suite in the requirements section?
  • verify repo locationhttp://software.open-xchange.com/OX6/6.22/frontend/RHEL6/ ? Or OX6/stable? or something else?
  • I was unable to get one single unanimous answer on how to correctly write the product name of the product with the code name OX7. I used OX App Suite in this document. Please search/replace if this is not correct.
  • verify this logging adjustment for apache. in my centos box the syntax ${APACHE_LOG_DIR}/error.log works not. however, it is not from me, it is from install guide in wiki

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 7.0.2.

Requirements

Add Open-Xchange Repository

We start by adding some OX6 frontend repos to our yum repos. 

# /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>
                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

	        RewriteRule v=\w+/(.+) $1 [L]

	        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.
