2、下载新的 CentOS-Base.repo 到 /etc/yum.repos.d/CentOS 7版本：
或者

[root@centos yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo --2021-11-22 11:07:13--https://mirrors.aliyun.com/repo/Centos-7.repo Resolving mirrors.aliyun.com (mirrors.aliyun.com)... 61.162.46.214, 61.162.46.210, 61.162.46.208, ...

3、运行 yum makecache 生成缓存

[root@centos yum.repos.d]# yum makecache Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com base| 3.6 kB00:00:00 extras| 2.9 kB00:00:00 updates| 2.9 kB00:00:00 (1/6): extras/7/x86_64/filelists_db| 259 kB00:00:01 (2/6): extras/7/x86_64/other_db| 145 kB00:00:02 (3/6): base/7/x86_64/other_db| 2.6 MB00:00:02 (4/6): updates/7/x86_64/other_db| 829 kB00:00:01 (5/6): base/7/x86_64/filelists_db| 7.2 MB00:00:06 (6/6): updates/7/x86_64/filelists_db| 6.6 MB00:00:08 Metadata Cache Created [root@centos yum.repos.d]#

4、查看更换的阿里云镜像的仓库是否生效。

[root@centos yum.repos.d]# yum clean all Loaded plugins: fastestmirror Cleaning repos: base extras updates Cleaning up list of fastest mirrors Other repos take up 41 M of disk space (use --verbose for details) [root@centos yum.repos.d]# yum repolist Loaded plugins: fastestmirror Determining fastest mirrors * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com base| 3.6 kB00:00:00 extras| 2.9 kB00:00:00 updates| 2.9 kB00:00:00 (1/4): base/7/x86_64/group_gz| 153 kB00:00:00 (2/4): extras/7/x86_64/primary_db| 243 kB00:00:00 (3/4): updates/7/x86_64/primary_db|12 MB00:00:02 (4/4): base/7/x86_64/primary_db| 6.1 MB00:00:03 repo idrepo namestatus base/7/x86_64CentOS-7 - Base - mirrors.aliyun.com10,072 extras/7/x86_64CentOS-7 - Extras - mirrors.aliyun.com500 updates/7/x86_64CentOS-7 - Updates - mirrors.aliyun.com2,963 repolist: 13,535 [root@centos yum.repos.d]#
