> centos替换源的时候，今天才知道，老版本的源华为和阿里云，已经不做维护了，需要把源修改为http://vault.centos.org 的，才可以正常的访问。

下图可以看到centos的各个版本源信息。

## 查看系统信息 ##

#查看版本信息
    rpm -qi centos-release 
    
    #查看系统信息
    uname -a 
    
    #查看redhat版本
    cat /etc/redhat-release
    
    #查看linux版本信息
     cat /proc/version

## 替换源 ##

#这个是阿里云的源
    #wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
    #目测现在6版本已经不维护了
    wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.huaweicloud.com/repository/conf/CentOS-6-anon.repo
    
    #需要替换为 http://vault.centos.org
    sed -i "s#https://mirrors.huaweicloud.com#http://vault.centos.org#g" CentOS-Base.repo
    #清空缓存
    yum clean all
    
    #生成缓存信息
    yum makecache

下图可以看到，华为云，已经不维护老版本的centos了

配置信息  
$releasever 这个变量，就是命令`rpm -qi centos-release` 的变量信息。 我们使用下面的配置就可以正确的更新源了。

# 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.
    #
    #

## 常见问题 ##

https://mirrors.huaweicloud.com/centos/6/os/x86\_64/repodata/repomd.xml: \[Errno 14\] PYCURL ERROR 22 - “The requested URL returned error: 404 Not Found”

出现这个问题，是由于华为已经不维护centos6版本的源了。
