What is CentOS?

CentOS is 100% compatible rebuild of the Red Hat Enterprise Linux, in full compliance with Red Hat’s redistribution requirements. CentOS is for people who need an enterprise class operating system stability without the cost of certification and support.

Following the release of RHEL 5.4, CentOS 5.4 has just hit the CentOS mirrors. Time to update the Local CentOS YUM repository script.

Adding CentOS 5.4 to the YUM repository script

Create the following additional Directories for CentOS 5.4:

# mkdir -p /var/www/html/centos/5.4/os/i386
# mkdir -p /var/www/html/centos/5.4/updates/i386
# mkdir -p /var/www/html/centos/5.4/os/x86_64
# mkdir -p /var/www/html/centos/5.4/updates/x86_64

Add the CentOS 5.4 repository to the bash script which will rsync your local YUM repository server with a CentOS 5.4 YUM mirror.
