Since this post has gotten a lot of attention over the years, I've listed the top solutions per platform at the bottom of this post.
I want my node.js server to run in the background, i.e.: when I close my terminal I want my server to keep running. I've googled this and came up with this tutorial, however it doesn't work as intended. So instead of using that daemon script, I thought I just used the output redirection (the
2>&1 >> file part), but this too does not exit - I get a blank line in my terminal, like it's waiting for output/errors.
I've also tried to put the process in the background, but as soon as I close my terminal the process is killed as well.

myapp.service file (replacing 'myapp' with your app's name, obviously):
[Unit] Description=My app [Service] ExecStart=/var/www/myapp/app.js Restart=always User=nobody # Note Debian/Ubuntu uses 'nogroup', RHEL/Fedora uses 'nobody' Group=nogroup Environment=PATH=/usr/bin:/usr/local/bin Environment=NODE_ENV=production WorkingDirectory=/var/www/myapp [Install] WantedBy=multi-user.target
Note if you're new to Unix:
/var/www/myapp/app.js should have
#!/usr/bin/env node on the very first line.
Copy your service file into the
Start it with
systemctl start myapp.
Enable it to run on boot with
systemctl enable myapp.
See logs with
journalctl -u myapp
