Earlier we have done node.js installation through source package , you can find here that post from below link. Node.js Installation from Source . Here we are going to install node.js through two method first one is from EPEL repository and other from Node Version Manager ( NVM ) .

Method 1 :  Install Node.js from EPEL Repository

I am going to configure node.js  on Centos 8 Server. first, we need to configure EPEL on CentOs 6 / 7 / 8 Version from the below link of the article.

EPEL Repository Installation on CentOS

After installation  run the below command for installation of node.js . I am assuming you have root previlage of server , otherwise if you have user sudo previlage , you need to use sudo before command.

# yum install nodejs

  npm-1:6.13.4-1.10.19.0.1.module_el8.1.0+277+2bccb1a9.x86_64

Check Version Installed

[root@localhost ~]# node --version
v10.19.0

Method 2 :  Install Nodejs from Node Version Manager ( NVM )

The second method we are using through nvm tool, that can manage node easily. To install nvm on centos 7, you can download and execute the script from the git hub repository. Below are two commands, which you can use to download and execute the script from curl and wget command. Follow the below commands.

# curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash

After run one of the command , the script output should be like below.

OUTPUT 

% Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 7750 100 7750 0 0 32751 0 --:--:-- --:--:-- --:--:-- 32838 => Downloading nvm as script to '/root/.nvm' => Appending source string to /root/.bashrc => Close and reopen your terminal to start using nvm

From nvm  list-remote command show which version of node its having in it. See the below output of below command.

# nvm list-remote

OUTPUT : 

....

....

        v12.12.0
       v12.13.0   (LTS: Erbium)
       v12.13.1   (LTS: Erbium)
       v12.14.0   (LTS: Erbium)
       v12.14.1   (LTS: Erbium)
       v12.15.0   (LTS: Erbium)
       v12.16.0   (LTS: Erbium)
       v12.16.1   (LTS: Erbium)
       v12.16.2   (Latest LTS: Erbium)
        v13.0.0
        v13.0.1
        v13.1.0
        v13.2.0
        v13.3.0
        v13.4.0
        v13.5.0
        v13.6.0
        v13.7.0
        v13.8.0
        v13.9.0
       v13.10.0
       v13.10.1
       v13.11.0
       v13.12.0

Now you can select a version of node , which you require from list and install from below command,Here I am going to install latest stable version of node from nvm command.

# nvm install v13.12.0

If you have install earlier also node any version on server , you can see the version on server installed by list parameter and current use version of node.

# nvm list

Here I have fresh install stable version , so there is not any difference. Check below image.

If you got different version on server of node install , you can switch between them from below command.

To set any version which you want use below command .

# nvm use  v13.12.0

For set default version , use alias parameter with nvm and node version.

To set this version as the default, type:

# nvm alias default [VERSSION]

Check Installed  Node.js Version 

Once the installation is done, you can check through the below command to check the node.js version.

# node --version
v13.12.0

Thanks
