I have a nodejs to run on Ubuntu. However, i'm using Putty (i'm a windows user) to connect to the server.

The apps runs fine, the only problem that i have that as soon as i close Putty (Session), so does the nodejs stop running.

Is there any specific command should i run instead 'node server.js' ? Any help is appreciated

Thanks

You can handle this situation very efficiently by installing pm2.

PM2 is a daemon process manager that will help you manage and keep your application online 24/7

Installation

The latest PM2 version is installable with NPM or Yarn:

$ npm install pm2@latest -g
// or 
$ yarn global add pm2

Start an app in background

The simplest way to start, daemonize and monitor your application is by using this command line:

$ pm2 start app.js

Once you've done this, you can simply close your putty session and your NodeJS server will keep running as a daemon in the background.

Start your app as a service.

For that create a systemd unit file under /lib/systemd/system/my-app.service with the following content:

[Unit]
Description=my-app description
After=network-online.target

[Service]
ExecStart=/usr/bin/node /opt/.../index.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=/opt/.../

[Install]
WantedBy=multi-user.target

Then tell systemd to detect the new service systemctl daemon-reload. After that enable & start your service:

systemctl enable my-app
systemctl start my-app

Then it starts automatically after a reboot & keeps running if you logout.
