Make your NodeJS app run as a service in Linux
This is an example where you can make your NodeJS app (also MEAN or MERN stack app) run as a service in your Linux server. Here we create the app "My NodeJS App".
1. Firtly, add this to the first line of your main nodeJS app file. Here it is the file server.js:
2. Add the service in the folder /etc/systemd/system/:
sudo vim mynodejsapp.service
[Unit] Description=My NodeJS App [Service] ExecStart=/var/www/apps/mynodejsapp/server.js Restart=always User=nobody Group=nogroup Environment=PATH=/usr/bin:/usr/local/bin Environment=NODE_ENV=production WorkingDirectory=/var/www/apps/mynodejsapp [Install] WantedBy=multi-user.target
If you have Red Hat (RHEL) or Fedora as an OS, then you have to use "nobody" as a group. "nogroup" is used in Ubuntu and Debian.
3. To start the app automatically on system boot:
sudo systemctl enable mynodejsapp
4. Start the app
sudo systemctl start mynodejsapp
5. Check the status of your app, restart, stop, etc. with the command "systemctl":
sudo systemctl status mynodejsapp
sudo systemctl stop mynodejsapp
