【centos8】更换国内阿里源

1、国内各大yum源

阿里源

https://developer.aliyun.com/mirror/centos?spm=a2c6h.13651102.0.0.3e221b11G5ZGvj

 

 

2、备份本机yum源

 

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

 

3、替换源 

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo

 

 

4、清理并生成缓存

yum clean all && yum makecache

 

 

具体可以参考阿里源官方文档配置
