There is some instruction how to make centralized repository for CentOS software.
As repository I have used my own Debian machine. Firstly, I have installed createrepo. This program generate some metadata which is necessary for RPM repository. Run
apt-get install createrepo
to install it from yum repository. Create two directories in the DocumentRoot environment. In my case its /var/www/html/ :
mkdir -pv /var/www/html/centos/5/{os,updates}/i386
Now copy packages from your CD/DVD installation disk to ./centos/5/os/i386 directory.
As I have an image file I should mount it first:
mount -o loop ~/CentOS-5.3-i386-bin-DVD.iso /mnt/dvd/
Only after you may start to copy:
cp /mnt/dvd/CentOS/* /var/www/html/centos/5/os/i386/
Its can take a while.
Also you need to get updates for your repository:
rsync -avrt rsync://mirror.web-ster.com/centos/5/updates/i386 --exclude=debug/
Take a look about more suitable rsync mirror for you here. It’s good idea to keep this directory updated all the time via cron.
Generate metadata for both directories.
cd /var/www/html/centos/5/os/i386/ && createrepo .
cd /var/www/html/centos/5/updates/i386/ && createrepo .
For server side is done. Please pay attention that your web-server should be run to keep the repository available.
Client side:
Backup your *.repo files in your /etc/yum.repos.d:
for i in *.repo; do mv $i $i.bak; done
And new one CentOS-Base.repo config with next context:
[base]
name=CentOS-$releasever - Base
baseurl=http://{IP address of your server}/centos/$releasever/os/$basearch/
gpgcheck=0
[update]
name=CentOS-$releasever - Updates
baseurl=http://{IP address of your server}/centos/$releasever/updates/$basearch/
gpgcheck=0
This steps should be repeated for each client machine.
