Using systemd to run a simple process and keep it up
Short post about using systemd to run a simple process :)
You'll need a service file.
For the most part systemd services are registered in config files stored in /etc/systemd/system/XXX.service
For example, running a minecraft server would look like this:
# /etc/systemd/system/minecraft-server.service
[Unit]
Description=Minecraft Server
[Service]
WorkingDirectory=/root/minecraft-server
ExecStart=/usr/bin/java -Xmx6G -Xms4G -jar /root/minecraft-server/server.jar nogui
Restart=on-failure
RestartSec=5
[Install]
WantedBy=multi-user.target
For extra docs on systemd settings , checkout: https://www.freedesktop.org/software/systemd/man/systemd.directives.html
Load your service intp systemd
systemctl daemon-reload
systemctl enable minecraft-server
systemctl start minecraft-server
Check logs
To check the logs of your systemd service, you can use systemctl, or us journalctl
systemctl status minecraft-server
journalctl -e -u minecraft-server
Cheers!
