Tomcat management script - can manage multiple tomcat instances under a common folder
#!/bin/bash
#
# Tomcat 7/8 start/stop/status script
# Forked from: https://gist.github.com/miglen/5590986
# @author: Sandeep Chaturvedi <[email protected]>
#
# Release updates:
# Updated to handle multiple tomcat instances under one directory
# 'status' argument without any other argument will print all instances' status
# any argument with the name of the tomcat instance (the subdirectory name under the common directory) will operate on that instance
# Updated method for gathering pid of the current proccess
# Added usage of CATALINA_BASE
# Added coloring and additional status
# Added check for existence of the tomcat user
#set -x
#Location of JAVA_HOME (bin files)
#export JAVA_HOME=/etc/alternatives/java_sdk
#Add Java binary files to PATH
#export PATH=$JAVA_HOME/bin:$PATH
#CATALINA_HOME is the location of the bin files of Tomcat
#export CATALINA_HOME=/opt/forgerock/tomcat/openam
# this is the directory under which different tomcat instances are

#TOMCAT_USER is the default user of tomcat

#SHUTDOWN_PORT is the default user of tomcat
