Answer 1

Use "screen". "Screen is a console application that allows you to use multiple terminal sessions within one window. The program operates within a shell session and acts as a container and manager for other terminal sessions, similar to how a window manager manages windows." (ref: info )

apt-get install screen

# Create a session called "my_app"
screen -S my_app

# Now you are inside another shell
xvfb-run npm start

# After that, you can detach the screen or close the connection

When you want to connect again to the screen, you must use reattach option -r .

screen -r my_app

To list active screens:

screen -ls

Answer 2

Is kind off old but here my answer might be help someone.

1. Create a execution file for pm2 (process.json) with the next. Substituting for your specific case.

{
  "apps" : [{
    "name"        : "<your_app_name>",
    "script"      : "<your_main.js>",
    "env": {
      "DISPLAY": ":99"
    }
  },
    {
      "name"        : "Xvfb",
      "interpreter" : "none",
      "script"      : "Xvfb",
      "args"        : ":99"
    }]
}

2. Move this file to your dist folder or where your main files is stored.
3. Execute pm2 start process.json .

You should see both projects executing.
