Auto Restart When Service Fail Nodejs

aaP_waterisop153

In the last few days, the project I am running keeps crashing every day. Because I don't want to be down for too long, I thought maybe there was another method to keep the project running while I looked for a way to resolve the issue.
Is there a way to make my nodejs project automatically restart if it crashes? just like in PM2 manager.

Hello,
For reference, you can use Cron to add command checking. Please replace 111 with your project name.

pid=`ps aux|grep $(cat /www/server/nodejs/vhost/pids/111.pid)|grep -v grep|wc -l`
echo ${pid}
if [ "${pid}" == "0" ];then
 bash /www/server/nodejs/vhost/scripts/111.sh
fi

For production i will prefer a systemd service so the OS itself handles restarts. Create a unit file and set Restart=on-failure (or always) and systemd will restart the Node process if it exits. it works well together with a process manager or Docker.
