Rebuild your the default CentOS yum.repo.d folder

On a dev machine, somehow, I managed to erase my yum.repo.d contents. I wanted to rebuild the repo files back to their default. First you need to figure out what version you are using:

• cat /etc/redhat-release

Then visit the correct release at : http://vault.centos.org/

• navigate to the correct os/x86_64/CentOS/ directory (could be os/x86_64/CentOS/ i386/)
• Download the following files to the server:
• wget http://vault.centos.org/5.x/os/x86_64/CentOS/centos-release-notes-5.x-0.x86_64.rpm
• wget http://vault.centos.org/5.x/os/x86_64/CentOS/centos-release-5-x.el5.centos.x86_64.rpm
• Then install the two rpms:
• rpm -Uivh *.rpm

Should be back to the original shipping repo files.
