How To Install Spacewalk on CentOS 6

Install Spacewalk on CentOS 6

In this tutorial, we will show you how to install Spacewalk on CentOS 6. For those of you who didn’t know, Spacewalk is the package and system management solution for Redhat-derived Linux operating systems such as CentOS, Scientific Linux, and Fedora, by the spacewalk community. It is released under the GPLv2 license. It offers a more flexible way to do it. Spacewalk enables you to inventory your systems, manage configuration, act as a central repository for your systems, monitor your systems, and so on.

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. I will show you the step-by-step installation of Spacewalk on CentOS 6.


  • A server running one of the following operating systems: CentOS 6.
  • 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 Spacewalk on CentOS 6

Step 1. First, you need to enable a repository on your system.

rpm -Uvh http://yum.spacewalkproject.org/2.0/RHEL/6/x86_64/spacewalk-repo-2.0-3.el6.noarch.rpm
rpm -Uvh http://mirror.muntinternet.net/pub/epel/6/i386/epel-release-6-8.noarch.rpm
wget http://www.jpackage.org/jpackage50.repo
mv jpackage50.repo /etc/yum.repos.d/

Step 2. Install PostgreSQL database.

Spacewalk uses a database to store its primary data, it supports either  PostgreSQL or Oracle RDBMS. In our case we are using PostgreSQL:

yum install spacewalk-setup-postgresql -y

Step 3. Install Spacewalk.

yum install spacewalk-postgresql -y

Step 4. Configure Spacewalk.

If you have installed an embedded database, then use it. It will ask you to enter the admin mail and organization details to generate the self-signed certificate for secured access:

[root@idroot.us ~]# spacewalk-setup --disconnected
