Yum Priorities - Clarkconnect 5.0 / Centos

HOWTO - Add yum priorities plugin to ClearOS5.1 / ClarkConnect 5.0 so that additional repositories and additional packages can be added without fear of breaking your existing install
INSTALL

Cribbed from this page
http://wiki.centos.org/AdditionalResources/Repositories?action=show&redi...

Grab the yum-priorities package from
http://mirror.centos.org/centos-5/5.5/extras/i386/RPMS/yum-priorities-1....

Check plugins=1 in /etc/yum.conf

Check it is enabled in /etc/yum/pluginconf.d/priorities.conf, add check_obsoletes=1 (to prevent high priority updates being overwritten by low priority packages)

Then edit /etc/yum.repos.d/base.repo and centos.repo to reflect your priorities. Default is 99 (i.e. lowest) 1 is highest. Set everything in base.repo and centos.repo to highest by adding priority=1 after each repo. Should look like this:-

Do the same for /etc/yum.repos.d/centos.repo, adding priority flag also (set to 1)

OPTIONAL - Add RPMForge / DAG, Dries, RPMFind

rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

Edit /etc/yum.repos.d/rpmforge.repo and add priority=70 (something low)

OPTIONAL - Add CentOSPlus. Create /etc/yum.repos.d/centos-plus-contrib.repo with:- (NOTE: Path fixed to 5.4 directory)

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
mirrorlist=http://mirrorlist.centos.org/?release=5.4&arch=$basearch&repo=centosplus
#baseurl=http://mirror.centos.org/centos/5.4/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5
priority=10

#contrib - packages by Centos Users
[contrib]
name=CentOS-$releasever - Contrib
mirrorlist=http://mirrorlist.centos.org/?release=5.4&arch=$basearch&repo=contrib
#baseurl=http://mirror.centos.org/centos/5.4/contrib/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5
priority=10

OPTIONAL - Add EPEL5 (Fedora EL5 compatible repo)

rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarc...

Edit /etc/yum.repos.d/epel.repo to enabled=0, priority=90

Some other useful commands:-

VIEW REPO'S:
I should add that ONLY the default CC Repo's are left enabled, all other extras are disabled, unless called by the --enablerepo flag as shown in the examples below. This is additional protection against inadvertent upgrades

yum repolist all

Loading "protect-packages" plugin
Loading "priorities" plugin
repo id              repo name                                 status

base-supplements     ClarkConnect 5.0 - Supplements            enabled
base-updates         ClarkConnect 5.0 - Updates                enabled
centos-os            CentOS 5.x - Operating System             enabled
centos-updates       CentOS 5.x - Updates                      enabled
centosplus           CentOS-$releasever - Plus                 disabled
contrib              CentOS-$releasever - Contrib              disabled
rpmforge             Red Hat Enterprise $releasever - RPMforg disabled

SHOW PRIORITIES:
You could add this command to /usr/local/bin/yum-priorities, and make it executable so that you don't have to remember it ;-)

sed -n -e "/^\[/h; /priority *=/{ G; s/\n/ /; s/ity=/ity = /; p }" /etc/yum.repos.d/*.repo | sort -k3n

priority = 1 [base-extras]
priority = 1 [base-kernels]
priority = 1 [base-os]
priority = 1 [base-supplements]
priority = 1 [base-updates]
priority = 1 [centos-os]
priority = 1 [centos-updates]
priority = 10 [centosplus]
priority = 10 [contrib]
priority = 70 [rpmforge]

TEMPORARILY ENABLE REPO:- e.g.

yum --enablerepo=* search php

yum --enablerepo=rpmforge list ntop

yum --enablerepo=epel list curl

yum --enablerepo=rpmforge install ntop
