It is time to register first client to your spacewalk server. In this example I will add machine jelena.setenforce.com as a client to my spacewalk server. For all packages I need I have to enable spacewalk client repository and EPEL repo. My client machine is CentOS 6.5.
Install certificate from spacewalk server:
You should ensure that spacewalk server is resolvable from client so put IP address and hostname in /etc/hosts file.
Also I would like to remote manage client form spacewalk and to upload some configuration files. For this purpose I choose osad. So install it and configure to start in boot time.
If you click on Systems tab in spacewalk Web console you will see that machine is register to Spacewalk.
