Centos8 配置阿里云yum源

1 进入yum目录

[root@test-138 ~]# cd /etc/yum.repos.d/
[root@test-138 yum.repos.d]# ll
-rw-r--r-- 1 root root 810 Jan 9 21:26 CentOS-AppStream.repo
-rw-r--r-- 1 root root 788 Jan 9 21:24 CentOS-Base.repo
-rw-r--r-- 1 root root 832 Jan 9 21:26 CentOS-Extras.repo　

2 将mirrorlist注释掉,缓存阿里的,gpgcheck换成0(暂不知道原因) 

CentOS-AppStream.repo:

baseurl=https://mirrors.aliyun.com/centos/$releasever/AppStream/$basearch/os/
gpgcheck=0

CentOS-BaseOS.repo:

baseurl=https://mirrors.aliyun.com/centos/$releasever/BaseOS/$basearch/os/
gpgcheck=0

CentOS-Extras.repo:

baseurl=https://mirrors.aliyun.com/centos/$releasever/extras/$basearch/os/
gpgcheck=0

 3 清空,重新缓存

[root@test-138 yum.repos.d]# yum clean all
0 files removed
[root@test-138 yum.repos.d]# yum makecache 
CentOS-8 - AppStream
