Enabling Tomcat as a systemd service

The simplest way to get Tomcat as a service working on a RHEL 7 / CentOS 7 / other systemd-based setup. Note that I'm not addressing any SELinux or FirewallD considerations here...

1. Make sure you've extracted a copy of Tomcat somewhere, and that you've populated its bin/ with at least export JAVA_HOME=/location-of-java & export CATALINA_OPTS="java+tomcat variables" for your environment.

2. adduser -r tomcat

3. Edit /etc/systemd/system/tomcat.service with the following. Make sure you adjust the paths in ExecStart + ExecStop accordingly.

Description=Apache Tomcat Web Application Container

4. systemctl enable tomcat && systemctl start tomcat

You can get the status of the instance by running systemctl status tomcat -l , and use the "stop" clause to stop the instance.
