How to Deploy Your Nodejs App on Centos 7

PM2 is a process manager for nodejs apps. It daemonizes apps built with nodejs, which means run-as-service.
Let’s install PM2 using npm.

1npm install -g [email protected]

Now you can start your app using pm2 like so:

1pm2 start app.js

Next, register the app as startup process.

1pm2 startup systemd
2pm2 save

You can check the currently running apps like so:

1pm2 list

Remember your app name or id so that you can use it to restart or stop the service.

1pm2 restart

Simply hitting pm2 command will show you pm2 help.
Happy coding! 🙂
