Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. In this tutorial, we will learn to install Node.JS on Ubuntu & CentOS machines.
(Recommended Read: – )
We need to have some packages like ‘gcc, gcc-c++’ installed on our systems. Install them on CentOS using the following command,
$ sudo yum install gcc gcc-c++
For Ubuntu, install them using the following command,
$ sudo apt-get install build-essential
Install NodeJS on Ubuntu
We can install either of the two available Node.JS versions i.e. 6 (which has long term support) or 9 (which is the latest version available). For installing Node.JS, we will add the official repositories on our system, use the following command to add the repository,
For Node.JS 6,
$ curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash –
For Node.JS 9,
$ curl -sL https://deb.nodesource.com/setup_9.x | sudo -E bash –
Once added, install Node.JS using the following command,
$ sudo apt-get install nodejs
We can also install Node.JS using the source code, method has been discussed below.
Install NodeJS on CentOS
On CentOS, we can either install Node.JS from EPEL repository or from official Node.JS repositories. Both methods have been shared below.
Using EPEL repository
To use this method for Node.JS installation, we need to add the EPEL repositories on our system first. Execute one of the following mentioned command, based on the OS & architecture being used,
$ sudo rpm -Uvh https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
RHEL/CentOS 6 (64 Bit)
$ sudo rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
RHEL/CentOS 6 (32 Bit)
$ sudo rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
Once done install, Node.JS using yum,
$ sudo yum install nodejs
Using Official repository
To use the official repository to install Node.JS, execute the following command based on the version needed,
$ curl –silent –location https://rpm.nodesource.com/setup_6.x | sudo bash –
$ curl –silent –location https://rpm.nodesource.com/setup_9.x | sudo bash –
Then install Node.JS using yum,
$ sudo yum install nodejs
Install NodeJS from source
We can also install Node.JS on both Ubuntu & CentOS by building it from source. Use the following process to install latest version of Node.Js i.e. version 9 on Ubuntu as well CentOS,
Download the latest source code,
$ wget https://nodejs.org/dist/v9.1.0/node-v9.1.0.tar.gz
$ tar -xvzf node-v9.1.0.tar.gz
$ cd node-v9.1.0
Next compile the source code with the following commands,
& install it using the following command,
$ sudo make install
This will install the latest version of Node.JS on your system. To check the version number of Node.JS, run the following command,
$ node – -version
