Liferay Portal with Tomcat


Note This User Guide is written specifically for a CentOS 7 64bit Liferay Portal with Tomcat (no Control Panel) template. This template comes with all the individual components for Liferay using MySQL already configured as a bundle.

If you only need to install Tomcat, you can either choose one of the Tomcat templates when you create your Virtual Server, or you can install Tomcat from the Control Panel after the Virtual Server has been created.

If you have made a mistake and installed the wrong template or applications, please contact eApps Support for assistance.

You will also need to make sure that you have enough memory available for Liferay. For a small Liferay deployment, start with 2048 MB (2.0 GB) of RAM, and be prepared to scale upwards as necessary.

eApps support for Liferay is limited to the installation of the application. Liferay is an enterprise application aimed at large corporations and organizations who have in-house or contract Java developers. If you need support or assistance with customizing Liferay or portlets, please see the Liferay Resources section of this user guide.

Using mod_jk or mod_proxy_ajp to bypass Apache

The mod_jk package comes preinstalled with the template.  You can create an Apache virtual host for the Liferay portal and all requests will be forwared to mod_jk automatically. The configuration file is loated at /etc/httpd/conf.d/mod_jk.conf and comes with the following default directives:


JkMount /* ajp13
# Directives to enable Apache to continue serving applications dependent on it.
SetEnvIf Request_URI "/webmail" no-jk
SetEnvIf Request_URI "/awstats
" no-jk
SetEnvIf Request_URI "/myadmin" no-jk
SetEnvIf Request_URI "/pgadmin
" no-jk
SetEnvIf Request_URI "/cgi-bin" no-jk
SetEnvIf Request_URI "/joomla
" no-jk
SetEnvIf Request_URI "/wordpress" no-jk
SetEnvIf Request_URI "/drupal
" no-jk
SetEnvIf Request_URI "/mailman*" no-jk


The mod_proxy_ajp module is already included with Apache as well. For mod_proxy_ajp add these directives to your VirtualHost block:

# Directives for your application
ProxyPass / ajp://localhost:8009/
ProxyPassReverse / ajp://localhost:8009/
# Directives for eApps applications dependent on Apache
ProxyPass /webmail !
ProxyPass /joomla !
ProxyPass /awstats !
ProxyPass /myadmin !
ProxyPass /cgi-bin !
ProxyPass /pgadmin !

More information about mod_jk and mod_proxy_ajp can be found in the Tomcat with Apache User Guide
