Patch Management of Linux Servers Using Spacewalk


Overview :

In this tutorial I am assuming that Spacewalk  server is already installed & Configured. Click Here to go through the spacewalk installation steps. In my scenario I have more than 100 Linux Servers (Centos 6) , I will do the patching using spacewalk tool. For this i have to register all linux servers in spacewalk and will push all updates from the admin panel

Follow the Below Steps to Register CentOS 6.4  servers in Spacewalk.

Step:1 Login To admin Panel of Spacewalk and add a Channel.

Click on channel —> then click on Manage software Channel —>  Click on Create New Channel

spacewalk-channel

Also select option “Public and may be accessed by any of the trusted organizations trusted by this organization” which is under Channel Access Control . Leave all other  fields as it is and click on Create channel.

Step:2 Now Create & add repository to the Channel

Go To Channel —-> click on Manage Repository

Specify the Repository Label and Path of Repository and Click on Create Repository, in my I have put the repository on ftp server.

Add Repository to Channel:

Now Click on Manage Software channel —-> then click on the channel Name —> then click on Repository —-> then select the repository that we have created in above step and then click on update repository

Step:3 Now Upload the Packages / RPMS to Channel using below command

# spacewalk-repo-sync --channel centos6_x86_all  --type yum

 

Step:4 Now Generate Activation Key, which will be used for Client Registration with Spacewalk

From the Overview , click on the Activation Key —-> then click on Create Key

Step:5 Install Spacewalk client’s packages on CentOS 6 Servers.

# yum install -y rhn-client-tools rhn-check rhn-setup rhnsd m2crypto yum-rhn-plugin rhncfg rhncfg-actions rhncfg-client

Now Register Linux Server with Spacwalk

# rhnreg_ks --force --serverUrl=http://192.168.2.51/XMLRPC --activationkey=1-6f0183f8cb1815adeebe38f4ffd445d6
