Install Spacewalk on CentOS 6

25 Comments

Spacewalk is an open source Linux systems management solution. Spacewalk is a community project and Red Hat Satellite has derived from Spacewalk. Spacewalk can manage all Red Hat derived Linux distributions like Fedora, CentOS, Scientific Linux, Oracle Linux,…

Spacewalk enables you to inventory your systems, manage configuration, act as central repository for your systems, monitor your systems and so on. You can choose to use PostgreSQL or Oracle Database XE (Express max 3GB database) database. I have been using Spacewalk with PostgreSQL for some time now and am quite happy with it. I currently have subscribed 40+ Linux systems in mixed distributions (CentOS 5, 6 and Oracle Linux 5, 6) and it works OK. I wonder how Spacewalk manages in environments with 100+, 200+ systems… In this post i will explain how to install Spacewalk with PostgreSQL on CentOS 6.

What Can Spacewalk Do?

Spacewalk is an open source (GPLv2) Linux systems management solution that allows you to:

  • Inventory your systems (hardware and software information)
  • Install and update software on your systems
  • Collect and distribute your custom software packages into manageable groups
  • Provision (kickstart) your systems
  • Manage and deploy configuration files to your systems
  • Monitor your systems
  • Provision and start/stop/configure virtual guests
  • Distribute content across multiple geographical sites in an efficient manner.

Pre-requisites – before you install Spacewalk:

  • 12GB or more free disk space on PostgreSQL partition
  • Working FQDN name resolution

Spacewalk configure script checks /usr/share/pgsql and /var/lib/pgsql locations (default PostgreSQL install location on CentOS) for disk space availability (< 12GB). You need to make sure more than 12GB of free space is available at these locations! You can solve this by creating a large root partition or to create new mount points with more that 12GB of free space.

Let’s Install Spacewalk on CentOS 6!

1. Disable SELinux and IPtables

For this guide SELinux and iptables were disabled and CentOS 6 was fully updated!

2. Install wget for Jpackage repo

[root@foo1 ~]# yum install wget -y

3. Set up necessary repositories

[root@foo1 ~]# rpm -Uvh http://yum.spacewalkproject.org/2.0/RHEL/6/x86_64/spacewalk-repo-2.0-3.el6.noarch.rpm
[root@foo1 ~]# rpm -Uvh http://mirror.muntinternet.net/pub/epel/6/i386/epel-release-6-8.noarch.rpm
[root@foo1 ~]# wget http://www.jpackage.org/jpackage50.repo
[root@foo1 ~]# mv jpackage50.repo /etc/yum.repos.d/

4. Install PostgreSQL database

In this guide we will be configuring Spacewalk to work with PostgreSQL database. Spacewalk has prepared automated install of PostgreSQL. It is simple, efficient and fast – the obvious choice.

[root@foo1 ~]# yum install spacewalk-setup-postgresql -y

5. Install Spacewalk

[root@foo1 ~]# yum install spacewalk-postgresql -y

6. Configure Spacewalk

Run spacewalk-setup in disconnected mode and enter the information it asks you for.

[root@foo1 share]# spacewalk-setup --disconnected

Click “Create Login” and voila! You are inside your Spacewalk instance. Now you need to add your systems in your Spacewalk Management, create Software Channels, Repositories, Configuration Channels and so on… We finished our “Install Spacewalk on CentOS 6” guide!

I will be covering all this in my next post on Spacewalk! Stay tuned! 🙂
