    Read archwiki about systemd/Timer or maybe original freedesktop documentation about systemd.timer.

    Create a file my_super_tomcat_restarter.timer in /etc/systemd/system/:

    [Unit]
Description=Superbly restart my tomcat service every 120 seconds!

[Timer]
OnBootSec=120sec
OnUnitActiveSec=120sec

[Install]
WantedBy=timers.target

    Create a file my_super_tomcat_restarter.service in /etc/systemd/system/ with the content:

    [Unit]
Description=Superbly restart tomcat service!

[Service]
Type=oneshot
ExecStart=/usr/bin/systemctl restart tomcat

    Execute from your terminal as root:

    systemctl enable my_super_tomcat_restarter.timer

    The timer should fire in 120 seconds and execute my_super_tomcat_restarter.service which in turn will restart your tomcat service.

    either add it in init.d or systemd based on your Linux distribution of yours. in both cases you have to be root to add your script.
