centos配置yum源

1、登录mirrors.163.com

2、点击centos后面的“centos使用帮助”

3、下载CentOS7-Base-163.repo

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

5、把CentOS7-Base-163.repo放到/etc/yum.repos.d/目录

6、验证163的repo是否正确配置。

指令如下： yum repolist all

7、使用yum时报错：http://mirrors.163.com/centos/6.5/os/i386/Packages/mlocate-0.22.2-4.el6.i686.rpm: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'mirrors.163.com'"Trying other mirror.

解决方法

在/etc/resolv.conf 添加nameserver 8.8.8.8
