*简单粗暴方案*

更换源来解决 yum install xxx 报错或卡慢

1.删除源配置文件

rm -f /etc/yum.repos.d/CentOS-Base.repo

2.直接编辑源文件

vi /etc/yum.repos.d/CentOS-Base.repo

3.粘贴如下代码，使用的aliyun

# 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.
#
