Running Multiple Instances of Tomcat on a Single Machine

Everything you need is here.

This is how I made it work:
Korays-MacBook-Pro:bin koraytugay$ export CATALINA_HOME="/Users/koraytugay/Tomcats/1"
Korays-MacBook-Pro:bin koraytugay$ export CATALINA_BASE="/Users/koraytugay/Tomcats/3"
Korays-MacBook-Pro:bin koraytugay$ ./startup.sh
Using CATALINA_BASE:   /Users/koraytugay/Tomcats/3
Using CATALINA_HOME:   /Users/koraytugay/Tomcats/1
Using CATALINA_TMPDIR: /Users/koraytugay/Tomcats/3/temp
Using JRE_HOME:        /Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home
Using CLASSPATH:       /Users/koraytugay/Tomcats/1/bin/bootstrap.jar:/Users/koraytugay/Tomcats/3/bin/tomcat-juli.jar
Tomcat started.
Korays-MacBook-Pro:bin koraytugay$ ./shutdown.sh
Using CATALINA_BASE:   /Users/koraytugay/Tomcats/3
Using CATALINA_HOME:   /Users/koraytugay/Tomcats/1
Using CATALINA_TMPDIR: /Users/koraytugay/Tomcats/3/temp
Using JRE_HOME:        /Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home
Using CLASSPATH:       /Users/koraytugay/Tomcats/1/bin/bootstrap.jar:/Users/koraytugay/Tomcats/3/bin/tomcat-juli.jar
Korays-MacBook-Pro:bin koraytugay$
