CentOS6系统yum源修改

CentOS6系统的yum源如果修改不对是无法在线更新的，各大镜像站包括原始安装包的配置已经不能更新成功了，同时也建议使用CentOS7或以上版本。

修改CentOS-Base.repo文件为以下内容即可，注意：6.10为目前的CentOS6的最后的版本，也可以修改为使用的对应版本。文章源自新逸网络-https://www.xinac.net/9216.html

修改原因：原始文件中使用$releasever标记版本号，在CentOS6系统中此值为6，但各大镜像站和官方镜像站已经没有名称为6的目录了，而是对应的详细的版本号，如6.10；所以原来的默认配置是无法更新的，必须修改才可以。文章源自新逸网络-https://www.xinac.net/9216.html

# 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.
