这篇文章主要介绍了CentOS7配置阿里云yum源的方法代码，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧

打开centos的yum文件夹

输入命令cd /etc/yum.repos.d/

用wget下载repo文件

输入命令wget http://mirrors.aliyun.com/repo/Centos-7.repo

如果wget命令不生效，说明还没有安装wget工具，输入yum -y install wget 回车进行安装。

当前目录是/etc/yum.repos.d/，刚刚下载的Centos-7.repo也在这个目录上

备份

				?

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

									[root@bogon yum.repos.d]# mkdir repo_bak

									[root@bogon yum.repos.d]# mv *.repo repo_bak/

									[root@bogon yum.repos.d]# ls

									repo_bak

下载新的CentOS-Base.repo 到/etc/yum.repos.d/

				?

									wget -O /etc/yum.repos.d/CentOS-Base.repo

				?

									[root@bogon yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

									--2018-02-09 16:33:46-- http://mirrors.aliyun.com/repo/Centos-7.repo

									[root@bogon yum.repos.d]# ls

									CentOS-Base.repo repo_bak

之后运行yum clean all 清除缓存，运行 yum makecache 生成新的缓存

				?

									[root@bogon yum.repos.d]# yum clean all

									Loaded plugins: fastestmirror

									Cleaning repos: base extras updates

									Cleaning up everything

									Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos

									Cleaning up list of fastest mirrors

									[root@bogon yum.repos.d]# yum makecache

									Loaded plugins: fastestmirror
