Do you know how to make the system automatically restart daemon service?

Time:10-06

I have made a daemon service in linux server. It is running well. The service file is stargate.service (in /etc/systemd/system).

[Unit]
Description=stargate

[Service]
Type=simple
PIDFile=/app/stargate/stargate.pid
ExecStart=/app/stargate/stargate.sh start
ExecReload=/app/stargate/stargate.sh restart
ExecStop=/app/stargate/stargate.sh stop

[Install]
Alias=stargate
WantedBy=default.target

If by some reasons, the daemon service is die and stop. Do you know how to make the system automatically restart the daemon service ? How to make the daemon service starts if server get rebooted?

CodePudding user response:

To respawn your service when it fails, add the following to the [Service] block:

[Service]
Restart=on-failure
RestartSec=3

If you wish to always restart when your service is killed use Restart=always

The RestartSec value is the delay between restart attempts.
