How To Install Slack on CentOS 7

Install Slack on CentOS 7

In this tutorial, we will show you how to install Slack on CentOS 7. For those of you who didn’t know, Slack is a cloud-based software that provides a team collaboration tool and services, founded by Stewart Butterfield. Slack offers a lot of IRC-like (Internet Relay Chat) features such as a persistent chat room channel organized by topic. Slack can be searchable including files, conversations, and people.

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 Slack 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).
  • An active internet connection.
  • 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 Slack on CentOS 7

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

yum clean all
yum install epel-release
yum -y update
yum install libappindicator

Step 2. Installing Slack on CentOS.

By default, the Slack package doesn’t come in the default repository of CentOS 7. Go to the Slack for Linux download page and download the latest Slack .rpm package:

wget https://downloads.slack-edge.com/linux_releases/slack-3.3.8-0.1.fc21.x86_64.rpm

After downloads are successful, now install Slack using the following command below:

sudo yum -y install slack-3.3.8-0.1.fc21.x86_64.rpm

Step 3. Accessing Slack on CentOS 7.

Now that you have Slack installed on your CentOS desktop, you can start it either from the command line by typing slack or by clicking on the Slack icon (Activities -> Slack).
