Next let’s install PM2, a process manager for Node.js applications. PM2 makes it possible to daemonize applications so that they will run in the background as a service.
Use npm to install the latest version of PM2 on your server:
· sudo npm install pm2@latest -g·
Copy
The -g option tells npm to install the module globally, so that it’s available system-wide.
Let’s first use the pm2 start command to run your application, hello.js, in the background:
· pm2 start hello.js
