Posted on by Mohammed Noufal | Updated:
Reading Time: 7 minutes

Node.js is a robust runtime environment for running JavaScript on your web server, making it a popular choice for developing scalable and high-performance applications. Node.js was not available in the AlmaLinux official repositories. However, you may still install Node.js using the NodeSource repository with up-to-date Node.js packages. Node.js is a versatile and well-supported platform that may help you reach your goals while developing web applications, APIs, or server-side applications.

This article will guide you through installing Node.js on AlmaLinux, allowing you to use the runtime environment's capabilities in your applications. To install Node.js on Linux (AlmaLinux), follow the steps below.

Prerequisites

  • The operating system (OS) for the purposes of this article is AlmaLinux OS 8.
  • Use the root or sudo command to acquire administrative access to your AlmaLinux system.

Step #1. Keeping the AlmaLinux server up to date

It's a good idea to ensure your system is up to date before installing Node.js. Run the following command to update your AlmaLinux system:

sudo dnf update

This command will update your system's package list and bring installed packages up to their most recent versions.

Step #2. Installing the necessary packages

To install the necessary packages required for Node.js installation, run the following command:

sudo dnf install curl dnf-plugins-core

Step #3. Listing available Node.js streams

To list the available Node.js streams, you can run the following command:

dnf module list nodejs

This command will provide you with a list of Node.js streams from which to choose.

Here is the output:

]# dnf module list nodejs

Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled

Note that according to the output shown above, the available Node.js version in AlmaLinux 8 for installation via DNF is Node.js 18. If you want to install one of the most recent Node.js versions, follow the instructions provided below in the section Step 4b regarding the use of of Node Version Manager (NVM) for installing Node.js.

Step #4. Using DNF or NVM to install Node.js on Linux (AlmaLinux)

Step #4a. Using DNF to install Node.js on Linux (AlmaLinux)

First, select the Node.js version you wish to install on your AlmaLinux system, then run the following command to complete the installation:

sudo dnf module install nodejs:18

Enter y when prompted to import the repository's GPG key, then press the Enter key.

Here is the output:

]# sudo dnf module install nodejs:18

Complete!

Run any of the following commands to check if Node.js is installed correctly:

node --version
node -v

Here is the output:

]# node --version
V18.18.2
]# node -v 
v18.18.2 

NPM (Node Package Manager) is included with Node.js and must not be installed separately. Use any of the commands below to show the current NPM version:

npm --version
npm -v

Here is the output:

]# npm --version 
9.8.1 
]# npm -v 
9.8.1 

Step #4b. Using Node Version Manager (NVM) to install Node.js on Linux (AlmaLinux)

Follow the installation instructions and source the appropriate configuration file based on your shell. To install NVM (Node Version Manager), download the installation script from GitHub with the following command.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/master/install.sh | bash

The command adds the NVM path to bash and tells the system to clone the NVM repository.

It's recommended to follow the official installation instructions provided on the NVM GitHub repository. By using this URL, you are ensuring that you are fetching the NVM installation script directly from a trusted source, which reduces the risk of potential security issues associated with running unknown scripts from the internet. However, it's still a good practice to review the script and understand what it does before executing it, and make sure you are using secure connections.

Here is the output:

=> Downloading nvm as script to '/root/.nvm'

=> Appending nvm source string to /root/.bashrc
=> Appending bash_completion source string to /root/.bashrc
=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

For the Z shell, run the following command to install NVM:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/master/install.sh | zsh

Then, source the bash configuration file to make NVM available in the current shell session:

source ~/.bashrc

For the Z shell, run the following command:

Installing multiple Node.js versions using Node Version Manager (NVM)

You can use Node Version Manager (NVM) to install and manage multiple Node.js versions on your system quickly. Keep reading to see how to install various Node.js versions using NVM.

Step #1. Installing NVM

If you haven’t already installed NVM, run the following command to install NVM:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash

Step #2. Listing available Node.js versions

To see the available Node.js versions that you can install, run the following command:

nvm ls-remote 

This command will display a list of Node.js versions you can install using NVM.

Step #3. Installing a specific Node.js version

To install a specific version of Node.js using NVM, run the following command:

nvm install <Node.js version>

Replace with the Node.js version you want to install. For example, to install Node.js 18 on Linux, run the following command:

nvm install 18

Here is the output:

]# nvm install 18
Downloading and installing node v18.18.2...
Downloading https://nodejs.org/dist/v18.18.2/node-v18.18.2-linux-x64.tar.xz...
####################################################################################################################################################################################################################################### 100.0%
Computing checksum with sha256sum
Checksums matched!
Now using node v18.18.2 (npm v9.8.1)

Step #4. Switching between Node.js versions

You can easily switch between installed Node.js versions. To switch to a Node.js version, run the following command:

nvm use <Node.js version>

This command sets the currently active Node.js version for your current shell session. For example, to switch to Node.js version 21.1, run the following command:

nvm use 21.1

Here is the output:

]# nvm use 21.1 
Now using node v21.1.0 (npm v10.2.0) 
]# node -v 
v21.1.0  

Step #5. Setting a default Node.js version

If you want to set a default Node.js version that will be used in new shell sessions, run the following command:

nvm alias default 21.1

Here is the output:

]# nvm alias default 21.1
default -> 21.1 (-> v21.1.0)

Step #6. Listing installed Node.js versions

To list the Node.js versions you have installed, run the following command

nvm ls

This command will display a list of the Node.js versions you have installed and indicate which one is currently in use.

Here is the output:

]# nvm ls 
       v18.18.2
->      v21.1.0
         system
default -> 21.1 (-> v21.1.0)
iojs -> N/A (default)
unstable -> N/A (default)
node -> stable (-> v21.1.0) (default)
stable -> 21.1 (-> v21.1.0) (default)
lts/* -> lts/iron (-> N/A)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.24.1 (-> N/A)
lts/erbium -> v12.22.12 (-> N/A)
lts/fermium -> v14.21.3 (-> N/A)
lts/gallium -> v16.20.2 (-> N/A)
lts/hydrogen -> v18.18.2
