Cobbler installation on CentOS/RHEL

Pre-Requisits

For this installation, we will need to have the following services installed: dhcp, bind & apache.

Install with the following yum command:

yum install httpd dhcp bind

If necessary, the dhcpd service can be restricted to servicing dhcp requests on just one port. To do this, edit the /etc/sysconfig/dhcpd file and set the following line:

DHCPDARGS=eth1

Adding the EPEL Repo to get cobbler

Download http://mirrors.coreix.net/fedora-epel/5/i386/epel-release-5-4.noarch.rpm (or whatever is suitable for the installed OS):

wget http://mirrors.coreix.net/fedora-epel/5/i386/epel-release-5-4.noarch.rpm

And install:

rpm -ivh epel-release-5-4.noarch.rpm

Install cobbler

Install using yum:

yum install cobbler cobbler-web

Check apache is working

Restart httpd:

service httpd restart

The following error might occur:

Starting httpd: Syntax error on line 10 of /etc/httpd/conf.d/cobbler.conf:
Invalid command 'WSGIScriptAliasMatch', perhaps misspelled or defined by a module not included in the server configuration
                                                           [FAILED]

If this error occurs, firstly remove mod_python:

rpm -e mod_python

Then, create a mod_wsgi config file:

cat > /etc/httpd/conf.d/05-load-wsgi.conf
LoadModule wsgi_module modules/mod_wsgi.so

And finally restart apache:

service httpd restart
