How To Install Spacewalk on CentOS 7

Install Spacewalk on CentOS 7

In this tutorial, we will show you how to install and configuration of Spacewalk on your CentOS 7. 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. 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 through the step-by-step installation of Spacewalk on the CentOS 7 server.

Install Spacewalk on CentOS 7

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

yum install epel-release

Add JPackage repository:

cat > /etc/yum.repos.d/jpackage-generic.repo << EOF
name=JPackage generic

Add Spacewalk repository:

rpm -Uvh

Step 2. Install the PostgreSQL database for Spacewalk.

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

Step 3. Install Spacewalk.

Now, install the Spacewalk server using the command:

yum install spacewalk-postgresql

Step 4. Firewall configuration.

Before we will be able to connect to our newly configured Spacewalk-server, we need to make sure that the firewall doesn’t block access:

sudo firewall-cmd --add-service=https --permanent
sudo firewall-cmd --add-service=http --permanent
sudo firewall-cmd --reload

Step 5. 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:

[ ~]# spacewalk-setup --disconnected
