node.js - How to run node js even on server restart -


i built nodejs project , runs smoothly. use forever service running file in background if server restarted daemon won't started automatically , should started manually. want run daemon server rebooted

you add forever command in .bash_profile every time server restart, command executed.

nano ~/.bash_profile forever start app.js # add command file, or whatever command using. source ~/.bash_profile # important, else changes not take effect

next time, on server restart, command run, hence creating daemon of node script.

note: maybe not best solution, 1 have got.

update

as @dlmeetei, suggested, can start nodejs app service can use features given linux service.

first create file in /etc/systemd/system, like:

touch /etc/systemd/system/[your-app-name].service nano /etc/systemd/system/[your-app-name].service

then, add , edit following script according relevance.

[unit] description=node.js example server #requires=after=mysql.service # requires mysql service run first  [service] execstart=/usr/local/bin/node /opt/nodeserver/server.js # required on systems # workingdirectory=/opt/nodeserver restart=always # restart service after 10 seconds if node service crashes restartsec=10 # output syslog standardoutput=syslog standarderror=syslog syslogidentifier=nodejs-example #user=<alternate user> #group=<alternate group> environment=node_env=production port=1337  [install] wantedby=multi-user.target

enable service, marks service starting on boot.

systemctl enable [your-app-name].service

manage service

systemctl start [your-app-name].service systemctl stop [your-app-name].service systemctl status [your-app-name].service # ensure app running systemctl restart [your-app-name].service
