前言

07 下载配置很完善的yum软件源

上面一个文章，我们说到，下载一个完善的Centos 7的软件源。那么本期文章就反过来，修改自己的Centos软件源，使其变成完善的软件源。

打开自己的Centos

觉得慢或卡的朋友，可以点击Enter，最多点两次就可以了，上面不用Enter也会默认选择第一个。

Centos展示界面

上面就懒得登录了，毕竟又不是不知道ip地址。

可能哪里配置不对，没有分配到ip地址，哈哈，打脸了。有知道的大佬可以说哈，小趴菜感激不尽。

软件源 CentOS-Base.repo

bash 复制代码

# 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.
