This guide demonstrates how to install Tomcat 7 in CentOS 6.3 as your primary Webserver. This uses Tomcat mod_jk connector for httpd and Tomcat 7 communications. This enables accesses to Tomcat application through port 80, and not having to explicitly enter the Tomcat port. We build mod_jk connector from the source. It is the assumption that you already have a running CentOS 6.3 system. You should also be logged to your system as root or a user with root privileges to use this procedure.
