1.编辑/etc/yum.repos.d/CentOS-Base.repo文件

[root@centos50 all_tarsync_installation]#vim /etc/yum.repos.d/CentOS-Base.repo

2.将其替换成以下内容

# CentOS-Base.repo
#
# 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.
#

3.清理缓存

# yum clean all  

4.更新缓存

 # yum makecache

小贴士：
清空一个文件内容的命令，例：清空etc/yum.repos.d/CentOS-Base.repo文件的内容

# cat /dev/null > /etc/yum.repos.d/CentOS-Base.repo
