This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Node.js on a Ubuntu 20.04 (Focal Fossa) server.
Install Node.js on Ubuntu 20.04 LTS Focal Fossa
Step 1. First make sure that all your system packages are up-to-date by running these following apt commands in the terminal.
Install Node.js and npm from Node Source
You simply need to add the PPA for the version you want to install:
curl-sLhttps://deb.nodesource.com/setup_14.x | sudo -E bash -
To install, run the commands below:
Once done, verify the installation by running:
Install Node.js and npm via Snap
Another way to install Node.js is via Snap package management:
Install Node.js and npm using NVM
NVM (Node Version Manager) is a bash script that allows you to manage multiple Node.js versions on a per-user basis.
So, first we’ll want to update our local repository index and then install libssl-dev and build-essential . That can be done by running the below commands in a terminal or shell:
Once those are installed you need to download the setup script for NVM. Typically you can grab this from their github page. Though at the time of this writing the newest version is in the command below:
curl-o-https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
Verify that the script is indeed the one you want and then run:
To begin the install of NVM. Once it finishes you will need to reload your profile to have your changes take effect without logging back in to your server again. Run the command:
Now as we have nvm installed, we can install isolated Node.js versions. To find out the versions of Node.js that are available for installation, we need to type:
[email@example.com~]# nvm ls-remote
Congratulation’s! You have successfully installed Node.js. Thanks for using this tutorial for installing Node.js on Ubuntu 20.04 LTS (Focal Fossa) system. For additional help or useful information, we recommend you to check the official Node.js website.
