Answer 1

Did you see the variables?

• CATALINA_HOME: This represents the root of your Tomcat installation. When we say, "This information can be found in your CATALINA_HOME/README.txt file" we mean to look at the README.txt file at the root of your Tomcat install.

• CATALINA_BASE Optionally, Tomcat may be configured for multiple instances by defining $CATALINA_BASE for each instance. If multiple instances are not configured, CATALINA_BASE is the same as CATALINA_HOME.

In the file apache-tomcat-7.0.42/bin/catalina.sh you will see:

# Only set CATALINA_HOME if not already set
[ -z "$CATALINA_HOME" ] && CATALINA_HOME=`cd "$PRGDIR/.." >/dev/null; pwd`

# Copy CATALINA_BASE from CATALINA_HOME if not already set
[ -z "$CATALINA_BASE" ] && CATALINA_BASE="$CATALINA_HOME"
