sudo apt replace
sudo apt dist-upgrade -y

Atmosphere="CATALINA_PID=/decide/tomcat/temp/tomcat.pid"
Atmosphere="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"

ExecStart=/decide/tomcat/bin/startup.sh
ExecStop=/decide/tomcat/bin/shutdown.sh

RestartSec=10
Restart=all the time

[Install]
WantedBy=multi-user.goal

Change JAVA_HOME variable with the one you famous earlier than.

Reload systemd daemon for the adjustments to take impact.

sudo systemctl daemon-reload
