CentOSyum不能用

修改/etc/yum.repos.d/Centos-Base.repo

# 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.

#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/

#其中url支持的协议有 http:// ftp:// file://三种。baseurl后可以跟多个url，你可以自己改为速度比较快的镜像站，但baseurl只能有一个
