Spacewalk Installation Steps on CentOS 6.X/RHEL 6.X

Step 1: Setup Spacewalk Repo.

# rpm -Uvh

Step 2: Setup Additional Repositories.

For Spacewalk on CentOS, RHEL 6 and Fedora, We nee additional dependencies that are needed from jpackage. Create a file using below command:

cat > /etc/yum.repos.d/jpackage-generic.repo 

Enable EPEL Repository: Spacewalk requires a Java Virtual Machine with version 1.6.0 or greater. EPEL – Extra Packages for Enterprise Linux contains a version of the openjdk that works with Spacewalk.

# rpm -Uvh

Step 3: Spacewalk Database Server Installation.

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

# yum install spacewalk-setup-embedded-postgresql

Step 4: Installing Spacewalk.

# yum install spacewalk-postgresql

Create a file under /root called ‘answer’ with below contents:

# vi /root/answers
admin-email = [email protected]
ssl-set-org = Nextstep4it
ssl-set-org-unit = IT
ssl-set-city = Delhi
ssl-set-state = Delhi
ssl-set-country = IN
ssl-password = spacewalkpasswd
ssl-set-email = [email protected]
ssl-config-sslvhost = Y

Now Install Spacewalk with an Answer File.

# spacewalk-setup --disconnected –answer-file=/root/answers

After spacewalk-setup is complete, the application is ready to use. The above command will create the PostgreSQL database environment for spacewalk and will create ssl certificates and will start the services like tomcat.

Step 5: Access the Spacewalk using the below URL and set an administrative account.

Open Web browser and type ‘https://[Hostname/IP]’, replace host-name or ip address according to your setup. After Setting the Administrative account, we can login to spacewalk admin GUI:
