I am planning to configure tomcat service to start automatically when a VM on Cloud starts.
Target servers are pega application server and pega batch server.
I want to change the settings to automatically start the tomcat service using systemd.

OS:RHEL 8.1
 

Please tell me about the following questions.

1.Where is the directory to place the unit file?
  (/usr/lib/systemd/system/tomcat.service) Is it correct?

2.Are the Unit file settings as follows?
