使用163开源镜像升级Centos

由于我的yum升级速度一直不太理想，今天发现一个牛人的blog上讲到使用163提供了centos的开源镜像，于是就抱着试试的态度，用过后果然不同凡响，哈哈！

操作过程如下，很简单的，做个笔记。



#cd /etc/yum.repos.d/
#cp -a CentOS-Base.repo CentOS-Base.repo.bak
#vim CentOS-Base.repo


CentOS-Base.repo内容如下

# 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.
