Overview

Node.js™ is an open-source server environment that runs JavaScript. It does not use threads and does not block processes. Because of this, it provides efficient resource management.
For more information about Node.js, visit the  Node.js website .

Requirements

Before you can install Node.js, your system must meet the following requirements:
  • You must possess root-level access to the server.
  • Your server’s package manager must function properly. For more information about package managers, read our  Package Manager Basics  documentation.

Install Node.js

Installing Node.js on servers running RHEL-derived operating systems

You can install Node.js on all  supported Red Hat® Enterprise License® (RHEL)-based operating systems  with one of the following methods:
  • In the interface, install the Node.js package in the Additional Packages section of WHM’s  EasyApache 4  interface (WHM » Home » Software » EasyApache 4).
  • On the command line, use your  package manager  to install one of the following packages:
  • ea-nodejs16
Note:If your system runs CentOS 7, you can only install the ea-nodejs16 package.
  • ea-nodejs18
  • ea-nodejs20
  • ea-nodejs22

Installing Node.js on servers running Ubuntu

To install Node.js on Ubuntu® operating systems run the following commands, where 20.x represents the Node.js version that you want to install:
curl -s https://deb.nodesource.com/setup_20.x | sudo bash
apt install nodejs npm
apt install ea-apache24-mod-passenger
ls -al /etc/cpanel/ea4/passenger*.system-default

Install a Node.js application

cPanel users can install Node.js web applications in one of the following ways:
  • Clone an existing application in cPanel’s  Git Version Control  interface (cPanel » Home » Files » Git Version Control).
  • Create a new application.
  • For information on how to do this for a RHEL-based server, read our  How to Install a Node.js Application  documentation.
  • For information on how to do this for a server that runs Ubuntu, AlmaLinux OS 9, or Rocky Linux™ 9, read our  Using Passenger Applications  documentation.
The  Node.js Foundation  provides a list of  Node.js applications . This list is not comprehensive.

Uninstall Node.js

You can uninstall Node.js from a server running an RHEL-derived operating system with one of the following methods:
  • In the interface, uninstall the Node.js package in the Additional Packages section of WHM’s  EasyApache 4  interface (WHM » Home » Software » EasyApache 4).
  • On the command line, use your  package manager  to uninstall your NodeJS package.
To uninstall Node.js from an Ubuntu server, run the following command:
apt-get purge --auto-remove nodejs


Troubleshoot Node.js

If you experience issues with your Node.js installation, use Phusion Passenger’s™  Troubleshooting Passenger Standalone and Node.js  documentation to troubleshoot the issue.
If you experience issues with the port on which your Node.js applications listens, use Phusion Passenger’s™  Reverse port binding in Node.js  documentation to troubleshoot the issue.

When you install Node.js, the package includes the following applications:
  •  Node.js 
  •  NPM  — A Node process manager.
  •  NPX  — A Node process runner.
The system stores these applications in the /opt/cpanel/ea-nodejs16/bin/ directory.
