How do I exclude a yum repository mirror?

Introduction

There may be times when yum cannot build the cache or search packages due to a bad repository mirror. You can exclude a specific repository mirror using the fastmirror.conf file in /etc/yum/

Procedure

Choose your favorite editor and modify the following file.

/etc/yum/pluginconf.d/fastestmirror.conf

Within the file, make sure that enabled= is set to 1 and under the #exclude, add a new line with exclude = name.of.mirror. Save the file and then rerun the yum clean all and yum makecache commands.

 yum clean all; yum makecache
