h2. Configure yum-priorities

the configuration of yum-priorities happens by adding a @priority@ setting to each repo-section

<pre><code class="bash">

vim /etc/yum.repos.d/CentOS-Base.repo

</code></pre>

add to each enabled section a @priority@ setting equal to @10@

<pre>

[base]

name=CentOS-$releasever - Base

mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os

#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/

priority=10

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

#released updates 

[updates]

name=CentOS-$releasever - Updates

mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates

#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/

gpgcheck=1

priority=10

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

</pre>

^Repo                 ^Section        ^Priority ^

^iRedMail.repo        ^iRedMail       |5        |

^CentOS-Base.repo     ^base           |10       |

^CentOS-Base.repo     ^updates        |10       |

^pgdg-92-centos.repo  ^pgdg92         |20       |

^virtualbox.repo      ^virtualbox     |20       |

^zabbix.repo          ^zabbix         |20       |

^rpmforge.repo        ^rpmforge       |30       |

^epel.repo            ^epel           |40       |

^adobe-linux-*.repo   ^adobe-linux-*  |60       |

h2. Test

actually not a test, but this one-liner gives you a sorted output of repo's and their configured priority

<pre><code class="bash">

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

</code></pre>

should give you a output like

<pre><code class="bash">

priority = 10 [base]

priority = 10 [updates]

priority = 20 [virtualbox]

priority = 30 [rpmforge]

priority = 40 [epel]

priority = 100 [adobe-linux-x86_64]

</code></pre>
