设置阿里云镜像
参考centos6 yum源失效的最新操作方式，解决：[Errno 14] PYCURL ERROR 22
1、备份

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

在这里插入图片描述
2、下载新文件

wget --no-check-certificate -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-6.repo

在这里插入图片描述

文件内容如下：

# 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.

3、替换源文件配置, 使用https://mirrors.aliyun.com/centos-vault/

sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo

sed -i  's/http/https/g' /etc/yum.repos.d/CentOS-Base.repo

我CenOS版本6.2

sed -i  's/$releasever/6.2/g' /etc/yum.repos.d/CentOS-Base.repo

sed -i  's/centos/centos-vault/g' /etc/yum.repos.d/CentOS-Base.repo

修改完后，内容如下

# CentOS-Base.repo
#
