Install Erlang on Ubuntu 16.04 LTS

In this tutorial, we will show you how to install Erlang on your Ubuntu 16.04 LTS server. For those of you who didn’t know, Erlang is a programming language used to build massively scalable soft real-time systems with requirements for high availability. The Erlang runtime system has built-in support for concurrency, distribution, and fault tolerance.

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 of Erlang in Ubuntu 16.04 LTS Xenial Xerus.

Install Erlang on Ubuntu 16.04 LTS

Step 1. First, make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.

First, download the Erlang repository package from its official website and install on your system:

wget https://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb 
dpkg -i erlang-solutions_1.0_all.deb

Now, you can install the erlang package on your system using the following command:

Step 3. Erlang Hello World Program.
