How To Configure Yum To Exclude A Mirror

Many of us have suffered from failing package repository mirrors. Some are slow, some won't have updated content, etc. You might want to remove/blacklist a particular mirror in your yum configuration.

Before trying to remove a mirror, install the fastest mirror plugin.

yum install yum-fastestmirror -y

The fastest mirror plugin is capable of determining mirror speeds and cache it. If that works for you well and good.

If not, manually exclude a mirror in /etc/yum/pluginconf.d/fastestmirror.conf. Use the exclude variable and set its value to the URL to be blacklisted.

Example

exclude = fedora.iitm.ac.in
