NodeJS on CentOS 8, RHEL 8 and Oracle Linux 8

As is well known, NodeJS is an open-source technology that allows you to expand the functionality of web applications. Basically, it is a Javascript implementation on the server-side. Mainly used in applications where constant and asynchronous communication between client and server is required.

If you use CentOS 8, RHEL 8 or Oracle Linux 8 it is likely that you are either an application developer or sysadmin. In both cases, it is likely that you will have to serve web applications and it is better than the system has NodeJS installed for easy deployment.

1) Using the EPEL repository

We have two ways to install NodeJS on CentOS 8, RHEL 8 and Oracle Linux 8. The first is to enable the EPEL repository.

EPEL is a pretty reliable repository that allows you to install a lot of packages in the distribution. All this without any problems.

It opens a terminal and runs the following:

:~$ su
:~#  dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

Then, install NodeJS by running the following command:

:~# dnf install nodejs

Finally, check the installed version.

:~# node -v
v10.14.1

2) Install NodeJS on CentOS 8, RHEL 8 and Oracle Linux 8 using the NVM

The first method is quite reliable and we even get an LTS version. However, it is likely that we need to have the latest version available. Using NVM this is possible.

NVM (Node Version Manager) is a utility that allows you to install and manage different versions of NodeJS.

First, you have to install curl to download NVM.

:~# dnf install curl

Then, download and install NVM.

:~# :~# curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash

Now, refresh the bash profile to use NVM.

:~# source ~/.bash_profile

Now you can list all versions of NodeJS available for download.

:~# nvm list-remote

For example, I will install the latest version.

:~# nvm install 12.7.0

Once the process is finished, check the installed version.

:~# node -v

And that is it.

Conclusion

As you can see Installing NodeJS is a simple process, especially for a technology quite powerful and used by many developers worldwide. We even have two ways to do it and it’s up to you to choose the best one.
