Install And Configure Spacewalk In CentOS 7

About Spacewalk

Spacewalk is a free, open source Linux management system. It is upstream community project for Red Hat Satellite server. Using Spacewalk, we can deploy, manage and update packages to Red Hat derived distributions like CentOS, Fedora, and Scientific Linux etc. It has a cool web interface that will help us to view the status of software updates in the clients and initiate update actions. Spacewalk provides provisioning capabilities that enables you to kickstart provision systems and manage and deploy configuration files. It also has virtualization capabilities to enable you to provision, control, manage, and monitor virtual KVM and Xen guests.

Spacewalk Proxy, the upstream version of Red Hat Satellite Proxy product, connects to your central Sapcewalk server and caches the contents from the Central server. Then, it distributes the contents to various geographical locations and reduces the load of the Central Spacewalk server. So, eventually, it reduces the downtime and increases the download speed for the client systems.

In this tutorial let us see how to install spacewalk and how to configure it in CentOS 7 64bit server. The same steps will work on Fedora and Scientific Linux distributions.


Using Spacewalk, you can:

  • 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 ;
  • Provision and start/stop/configure virtual guests ;
  • Distribute content across multiple geographical sites in an efficient manner ;
  • And many.

Install Spacewalk in CentOS 7

My testing machine details are given below:

  • Operating System : CentOS 7 minimal installation ;
  • Hostname : server1.unixmen.local ;
  • IP Address :

Before installing Spacewalk, we need to add some additional repositories that will help us to get some important dependencies which are not available in the Spacewalk official repository.

First, add EPEL repository:

Run the following command from your terminal to add and enable EPEL repository:

yum install epel-release

Add JPackage repository:

Run the following command from your Terminal to add JPackage repository:

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

Add Spacewalk repository:

Add Spacewalk official repository as shown below depending upon the distribution you use. As of writing this tutorial, the latest Spacewalk version was 2.3.

On RHEL/CentOS/Scientific Linux 6:

rpm -Uvh

On RHEL/CentOS/Scientific Linux 7:

rpm -Uvh

Fedora 20:

rpm -Uvh

Fedora 21:

rpm -Uvh

Since, I am using CentOS 7, I added the Spacewalk repository for CentOS 7.

Now, update the repository lists using command:

yum repolist && yum update

Install database server:

Spacewalk needs a database server to store it’s primary data. By default, Spacewalk uses an embedded PostgreSQL database. Also, you can use Oracle RDBMS (version 10g or higher) if you want.

We will go with defaults. Install postgreSQL database for Spacewalk using command:

yum install spacewalk-setup-postgresql

Install Spacewalk:

Now, install Spacewalk server using command:

yum install spacewalk-postgresql

Configure Firewall:

After installing Spacewalk, you need to allow few ports via your Firewall and router.

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

Also, add port 5222 if you want to push actions to client machines and 5269 for push actions to a Spacewalk Proxy, 69 udp if you want to use tftp.

Finally, restart firewall service using command:

firewall-cmd --reload

The installation part is over. Let us go and configure Spacewalk server.

Configure Spacewalk server

Your Spacewalk server must have a valid FQDN like In case your server fails to resolve it’s hostname, edit /etc/hosts file and add Spacewalk server’s hostname and IP address manually.

Here is my /etc/hosts file output: localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 server1.unixmen.local server1

Also, during Spacewalk configuration, you’ll be asked to enter a password for the Spacewalk database user. Please don’t use ‘#’ (number sign/pound/hash) and ‘@’ in your database password otherwise installation will fail.

Well, run the following command to configure the Spacewalk server:

spacewalk-setup --disconnected

Spacewalk server has been configured now. Now, let us go ahead and set up the password for the Spacewalk administrator account.

Open up your web browser and navigate to https://hostname/ or https://ip-address/.

Enter the administrator account name, password, first name, last name and Email address etc. Then, click Create Login button.
