#!/bin/env python2.7

"""
This creates an Apache Tomcat server version 7.0.63.

The front-end web server proxies incoming requests to the Tomcat server
listening on an unprivileged port.

The installer disables the AJP protocol, as well as the network port Tomcat
uses to terminate and relies on Linux signals to do so.

A cron job is created to restart the Tomcat server every 20 minutes if
it is not already running.

To start Tomcat, run: ~/webapps/<app_name>/bin/startup.sh
To stop Tomcat, run: ~/webapps/<app_name>/bin/shutdown.sh

Tomcat's main logging file is located at ~/logs/user/<app_name>.log

The official Tomcat documentation is available at
http://tomcat.apache.org/tomcat-7.0-doc/index.html

Some WebFaction specific tips can be found at the README.md file of
https://github.com/elromanos/webfaction-tomcat-7-installer/blob/master/README.md
