Yum encountered an error while starting the fastestmirror plug-in, which is a bug (http://yum.baseurl.org/ticket/70) of yum. If you stop mysqld,yum, everything works fine. The temporary workaround is to disable the launch of the fastestmirror plug-in when yum update.

The code is as follows:

Yum-disableplugin=fastestmirror update
