Install Spacewalk Server on CentOS 7

Spacewalk server is a free and open source Linux systems management software for provisioning, patching and configuration management of Spacewalk clients. Spacewalk is an upstream fork of Red Hat Satellite, a commercial fork developed by Red Hat. Spacewalk is distributed under GNU GPL v2 license.

In this article, we are installing Spacewalk server on CentOS 7.

Most of the configurations in this tutorial are command line based. Therefore, if you are new to Linux CLI then you should read Linux Command Line and Shell Scripting Bible, 3rd Edition by Wiley.

This Article Provides:

Spacewalk Features:

Some of the popular features of Spacewalk are.

Systems Inventory (Hardware and Software)
System Software Installation and Updates
System provisioning (via Kickstart)
Management and deployment of configuration files
Provision of virtual Guests
OpenSCAP Auditing of client systems

Environment Specification:

We have configured a CentOS 7 based virtual machine for this tutorial.

CPU - 3.4 Ghz (2 cores)
Memory - 2 GB
Storage - 20 GB
Operating System - CentOS 7.7
Hostname - spacewalk-01.example.com
IP Address - 192.168.116.213 /24

Installing Spacewalk and EPEL yum repositories on CentOS 7:

Connect with spacewalk-01.example.com using ssh as root user.

Spacewalk yum repositories are available at Spacewalk project website.

Download and install Spacewalk yum repository on CentOS 7.

[root@spacewalk-01 ~]# curl -s https://copr.fedorainfracloud.org/coprs/g/spacewalkproject/spacewalk-2.9/repo/epel-7/group_spacewalkproject-spacewalk-2.9-epel-7.repo > /etc/yum.repos.d/spacewalk.repo

Spacewalk requires some packages from EPEL (Extra Packages for Enterprise Linux). Therefore, we are also required to install EPEL before installing Spacewalk.

[root@spacewalk-01 ~]# yum install -y epel-release.noarch

Spacewalk also requires latest version of some Java packages that are not available in EPEL yum repository. However, Spacewalk provides a yum repository of it's own for these packages. Therefore, we are installing it as well.

[root@spacewalk-01 ~]# curl -s https://copr.fedorainfracloud.org/coprs/g/spacewalkproject/java-packages/repo/epel-7/group_spacewalkproject-java-packages-epel-7.repo > /etc/yum.repos.d/spacewalk-java.repo

Install PostgreSQL Database for Spacewalk:

Spacewalk needs a backend database for storing it's data. Current versions of Spacewalk supports PostgreSQL (8.4 or later) and Oracle RDBMS (10g or later).

Being a FOSS (Fan of Open Source Software), we definitely prefer PostgreSQL for this tutorial.

Spacewalk yum repository provides an embedded version of PostgreSQL for Spacewalk software.

We are installing this PostgreSQL database backend as follows.
