Making local yum rpm repositorie

Install createrepo

yum install  createrepo

Preparing

Make directory structure

• A directory called base which holds local copy of RPM's
• A directory called updates which holds the updates.

On this server which is a PXE install server the RPM's are already resident on the ftp server /var/ftp/install/centos52/CentOS/RPMS which I just link to the repositorie

mkdir -p /var/www/html/Centos/52/yum/updates
ln -s /var/ftp/install/centos52/CentOS/RPMS /var/www/html/Centos/52/yum/base

Creating repository headers

Now create the base repository headers: (Takes a couple of minuttes)
createrepo creates some files in a new repodata directory.

[root@ks ~]# createrepo /var/www/html/Centos/52/yum
[root@ks ~]# ls /var/www/html/Centos/52/yum/repodata
filelists.xml.gz  other.xml.gz  primary.xml.gz  repomd.xml

Updating the repository

Now update the repositorie
NOTE: rsync uses TCP port 873 which need to be open to the internet. Choose update sources from CentOS European Mirrors

/usr/bin/rsync -avrt rsync://mirrors.se.kernel.org/centos/5.2/updates/i386 --exclude=debug/ /var/www/html/Centos/52/yum/updates
