createrepo

A local yum repository server can be setup to allow caching of packages locally for various clients. To configure local repository server following steps can be used:

• Install rpmfusion, rpmforge and epel repositories
• Install createrepo package using 'yum -y install createrepo'
• Configure yum to keepcache for current server by making 'keepcache="1"' in /etc/yum.conf
• Rsync /var/cache/yum to /var/www/html (or appropriate document root folder for web server)
• For each folder in /var/cache/yum/x86_64/6 such as base, epel, etc. do following:
  • Go to /var/cache/yum/x86_64/6/<folder_name>/packages
  • Run 'createrepo -c cache_dir --update .'
• Create repository configuration file '<organization>.repo' with following contents:

[<organization>-base]
name=RHEL  - repo.<organization>.com - base
baseurl = http://repo.<organization>.com/x86_64/6/base/packages/
enabled = 1
protect = 0
gpgcheck = 0
keepcache = 0

[<organization>-epel]
name=RHEL  - repo.<organization>.com - epel
baseurl = http://repo.<organization>.com/x86_64/6/epel/packages/
enabled = 1
protect = 0
gpgcheck = 0
keepcache = 0

[<organization>-extras]
name=RHEL  - repo.<organization>.com - extras
baseurl = http://repo.<organization>.com/x86_64/6/extras/packages/
enabled = 0
protect = 0
gpgcheck = 0
keepcache = 0

[<organization>-rpmforge]
name=RHEL  - repo.<organization>.com - rpmforge
baseurl = http://repo.<organization>.com/x86_64/6/rpmforge/packages/
enabled = 1
protect = 0
gpgcheck = 0
keepcache = 0

[<organization>-rpmfusion-free-updates]
name=RHEL  - repo.<organization>.com - rpmfusion-free-updates
baseurl = http://repo.<organization>.com/x86_64/6/rpmfusion-free-updates/packages/
enabled = 1
protect = 0
gpgcheck = 0
keepcache = 0

[<organization>-rpmfusion-nonfree-updates]
name=RHEL  - repo.<organization>.com - rpmfusion-nonfree-updates
baseurl = http://repo.<organization>.com/x86_64/6/rpmfusion-nonfree-updates/packages/
enabled = 1
protect = 0
gpgcheck = 0
keepcache = 0

[<organization>-updates]
name=RHEL  - repo.<organization>.com - updates
baseurl = http://repo.<organization>.com/x86_64/6/updates/packages/
enabled = 1
protect = 0
gpgcheck = 0
keepcache = 0

• Replace <organization> with organization name everywhere. Ensure that repo.<organization>.com points to repository server being configured using /etc/hosts or DNS
• Copy this <organization>.repo file to some other machine at /etc/yum.repos.d/ Do not use the repository on same machine else /var/cache/yum of this machine would have additional folders for the same machines repository.
• Try to use yum and verify that local repository is visible

Updating repository with new packages

For all new packages following steps can be used:

• yum -y install <package> on repository server
• rsync /var/cache/yum/ to /var/www/html/
• For each folder in /var/cache/yum/x86_64/6 such as base, epel, etc. do following:
  • Go to /var/cache/yum/x86_64/6/<folder_name>/packages
  • Run 'createrepo -c cache_dir --update .'

Securing setup using HTTPS

The setup can be secured by using HTTPS certificates and by change baseurl to https://. For self-signed certificates refer to easy-rsa to learn how to create certificates and also to learn how to add certificate to host so that yum can use it.
