1. Change the source, sohu is quite easy to use.

1.1 backup centos-base.repo

Cd / etc/yum.repos.d/

Cp centos-base.repo centos-base.repo.bak

1.2 replace Source

Open centos-base.repo with vi and empty the content, then copy the following content in and save it.

# centos-base.repo

#

# this file uses a new mirrorlist system developed by lance davis for centos.

# the mirror system uses the connecting ip address of the client and the

# update status of each mirror to pick mirrors that are updated to and

# geographically close to the client. You should use this for centos updates

# unless you are manually picking other mirrors.

#

# if the mirrorlist= does not work for you, as a fall back you can try the

# remarked out baseurl= line instead.
