yum更改国内源

Posted 2020-10-26

centos 默认的源是国外的，访问下载的时候有点慢，用国内的源比较方便

需要先把原来的源的配置文件删了
rm -f CentOS-Base.repo
用如下两个命令下载yum源，只需要用到一个就可以
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
curl -O http://mirrors.163.com/.help/CentOS7-Base-163.repo

[[email protected] yum.repos.d]# ls
CentOS-CR.repo CentOS7-Base-163.repo
CentOS-Debuginfo.repo dvd.repo
CentOS-Media.repo epel-testing.repo
CentOS-Sources.repo epel.repo
CentOS-Vault.repo wget
CentOS-fasttrack.repo yum.repos.d.bak

用yum list可以查看yum的源
可以试着安装一个包试一下

验证是否是刚才下载的yum源生效
把下载的centos7的名字换成其他的名字在安装包就安装不了。恢复名字就可以安装
