# RHEL7.0配置aliyun #

**1、创建一个目录，用于存放原来的yum信息。我这里没有yum，就不创建目录了。**

[root@master ~]# cd /etc/yum.repos.d/
    [root@master yum.repos.d]# ls
    [root@master yum.repos.d]#

**2、下载镜像源**  
阿里云官方镜像网站：`https://developer.aliyun.com/mirror/`

[root@master yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
    --2020-06-03 07:23:24--  https://mirrors.aliyun.com/repo/Centos-7.repo
    Resolving mirrors.aliyun.com (mirrors.aliyun.com)... 36.249.75.120, 116.153.35.248, 116.153.35.246, ...

    [root@master yum.repos.d]# ls
    CentOS-Base.repo
    [root@master yum.repos.d]#

**3、生成缓存**

[root@master yum.repos.d]# yum makecache
    已加载插件：langpacks, product-id, subscription-manager
    This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
    http://mirrors.aliyun.com/centos/7Server/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
    正在尝试其它镜像。

    正在尝试其它镜像。

报错！！！！就要解决报错！！！百度一波！！！  
最终`repo`文件如下：

# 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.
