What would you like to do?
Running a Node.js application using nvm as a systemd service

Trickier than it seems.

1. Set up nvm

Let's assume that you've already created an unprivileged user named myapp. You should never run your Node.js applications as root!

Switch to the myapp user, and do the following:

  1. curl -o- | bash (however, this will immediately run the nvm installer - you probably want to just download the manually, and inspect it before running it)
  2. Install the latest stable Node.js version: nvm install stable

2. Prepare your application

Your package.json must specify a start script, that describes what to execute for your application. For example:

"scripts": {
    "start": "node app.js"

3. Service file

Save this as /etc/systemd/system/my-application.service:

Description=My Application



You'll want to change the User, Description and ExecStart/WorkingDirectory paths to reflect your application setup.

4. Startup script

Next, save this as /home/myapp/ (adjusting the username in both the path and the script if necessary):

. /home/myapp/.nvm/
npm start

This script is necessary, because we can't load nvm via the service file directly.

Make sure to make it executable:

chmod +x /home/myapp/

5. Enable and start your service

Replace my-application with whatever you've named your service file after, running the following as root:

  1. systemctl enable my-application
  2. systemctl start my-application

To verify whether your application started successfully (don't forget to npm install your dependencies!), run:

systemctl status my-application

... which will show you the last few lines of its output, whether it's currently running, and any errors that might have occurred.

You can avoid additional bash script by adding node path to systemd unit

@antono There are a few problems with that, though:

  1. Changing your version in nvm doesn't affect the service like it should.
  2. If nvm ever changes its storage layout, your service will stop working.
  3. Environment variables are not set; if something expects certain environment variables like the NODE_PATH to exist, it will break.

This is why I'm using a wrapper script - it ensures that the environment is set up exactly like it would have if you'd started the application yourself from a shell.

KillMode=process looks like it will only kill the start script and not any of the PIDs started by it. This should probably be omitted, or set to KillMode=control-group if you are finding systemctl stop my.service isn't being stopped properly.

Much better option:

ExecStart=/opt/nvm/nvm-exec yarn serve

@bryanlarsen this is awesome, works perfectly, even with screen:


ExecStart=/usr/bin/screen -dmL LOGFILE.log -S SCREEN-NAME /home/pi/.nvm/nvm-exec npm start --prefix /PATH-TO-YOUR-PROJECT

What does ". /home/myapp/.nvm/" do?
