本文介绍如何将CentOS系统的默认yum源更改为阿里云镜像源，并完成相关配置及验证安装过程。首先备份原始yum源文件，然后修改CentOS-Base.repo等文件中的源地址为阿里云地址，导入新的GPG密钥并生成缓存，最后验证安装gcc-c++成功。

一、进入yum.repo.d

[root@node-01 ~]# cd /etc/yum.repos.d/
 
[root@node-01 yum.repos.d]# ls
Centos-altarch-7.repo  CentOS-Base.repo  CentOS-Huawei.repo  epel.repo

二、备份原yum源

[root@node-01 yum.repos.d]# mkdir yum-back
 
[root@node-01 yum.repos.d]# mv CentOS-* yum-back/
 
[root@node-01 yum.repos.d]# ls
yum-back

三、替换yum源为阿里源

[root@localhost yum.repos.d]# cat Centos-altarch-7.repo 
# 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.
