How To Install Erlang on CentOS 7

Install Erlang on Ubuntu CentOS 7

In this tutorial, we will show you how to install Erlang on your CentOS 7. 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 the step-by-step installation of Erlang on a CentOS 7 server.


  • A server running one of the following operating systems: CentOS 7.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Erlang on CentOS 7

Step 1. First, let’s start by ensuring your system is up-to-date.

yum clean all
yum -y install epel-release

Step 3. Erlang Hello World Program.

nano helloworld.erl

Add the following content:

% hello world program
start() ->
io:fwrite("Hello World!\n").
