Apache Tomcat

Layout

The Apache Tomcat (CATALINA) home directory is:

/home/tomcat/apache-tomcat-v/

Where apache-tomcat-v is the version installed.

The CATALINA_HOME variable is set both in the Tomcat init script as well as setenv.sh files.

Starting and Stopping

There are two ways to start/stop/restart Tomcat.

  1. Via Module, using the Stop/Start/Restart buttons as shown below:
../../_images/tomcat-functions.png
  1. Via SSH, using the following commands
systemctl { start | stop | restart | status } tomcat
  1. If Tomcat is not responding, you can also issue, as root
pkill -9 java

Service

Tomcat runs as a system service.

The service file is located at /etc/systemd/system/tomcat.service
