linux 添加163源,CentOS yum 源设置为163的源操作步骤及配置文件参考

CentOS下可以通过yum很方便快捷的安装所需的软件和库，如果yum的源不好，安装速度会非常慢，CentOS默认官方源似乎都是国外的，所以速度无法保证，我一直使用163的源，感觉速度不错。下面就说说如何修改yum的源。

1、进入存放源配置的文件夹

cd /etc/yum.repos.d

2、备份默认源

mv ./CentOS-Base.repo ./CentOS-Base.repo.backup

3、使用wget下载163的源

wget http://mirrors.163.com/.help/CentOS-Base-163.repo

4、把下载下来的文件CentOS-Base-163.repo设置为默认源

mv CentOS-Base-163.repo CentOS-Base.repo

通过上述操作就把默认源修改为163的了。当然上述的操作可以合并为如下：mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

wget http://mirrors.163.com/.help/CentOS-Base-163.repo -O /etc/yum.repos.d/CentOS-Base.repo

5. 配置文件参考

[root@localhost yum.repos.d]# vi CentOS-Base.repo
