How do I run a node.js app as a background service?
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.
Original post :
I want my node.js server to run in the background, ie: 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.
So how can I leave it running when I shut down my local computer?

Copying my own answer from How do I run a Node.js application as its own process?
2015 answer : nearly every Linux distro comes with systemd, which means forever, monit, etc are no longer necessary - your OS already handles these tasks .
Make a 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 RHEL/Fedora uses 'nobody', Debian/Ubuntu uses 'nogroup'
Group=nobody
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 /etc/systemd/system .
Start it with systemctl start myapp .
Enable it to run on boot with systemctl enable myapp .
See logs with journalctl -u myapp

您可以使用Forever，一个简单的CLI工具来确保给定节点脚本连续运行（即永远）：https://www.npmjs.org/package/forever
UPDATE - As mentioned in one of the answers below, PM2 has some really nice functionality missing from forever. Consider using it.
Original Answer
Use nohup:
nohup node server.js &
EDIT I wanted to add that the accepted answer is really the way to go. I'm using forever on instances that need to stay up. I like to do npm install -g forever so it's in the node path and then just do forever start server.js
