Linux更换yum源

Posted 2023-05-03

参考技术A 有时候CentOS默认的yum源不一定是国内镜像，导致yum在线安装及更新速度不是很理想。这时候需要将yum源设置为国内镜像站点。国内主要开源的开源镜像站点应该是网易和阿里云了。

linux 更换yum源

1.备份原来的源

　　sudo mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bk

2.下载阿里的源

　　cd /etc/yum.repos.d

　　sudo wget -nc http://mirrors.aliyun.com/repo/Centos-7.repo

3.更改阿里的源为默认的源

　　sudo mv CentOS-7.repo CentOS-Base.repo

4.更新本地的源缓存

　　全部清除 

　　sudo yum clean all 

　　更新列表 

　　sudo yum list

　　缓存yum包信息到本机，提高搜索速度 

　　 sudo yum makecache
