1、安装Centos后默认的Yum源如下

**ll /etc/yum.repos.d/**

**\[root@localhost ~\]\# ll /etc/yum.repos.d/**

**total 32**

**-rw-r--r--. 1 root root 1664 Nov 23 21:16 CentOS-Base.repo**

**-rw-r--r--. 1 root root 1309 Nov 23 21:16 CentOS-CR.repo**

**-rw-r--r--. 1 root root 649 Nov 23 21:16 CentOS-Debuginfo.repo**

**-rw-r--r--. 1 root root 314 Nov 23 21:16 CentOS-fasttrack.repo**

**-rw-r--r--. 1 root root 630 Nov 23 21:16 CentOS-Media.repo**

**-rw-r--r--. 1 root root 1331 Nov 23 21:16 CentOS-Sources.repo**

**-rw-r--r--. 1 root root 5701 Nov 23 21:16 CentOS-Vault.repo**

2、把默认Yum源备份(可选)

**\[root@localhost ~\]\# mkdir /opt/centos-yum.bak**

**\[root@localhost ~\]\# mv /etc/yum.repos.d/\* /opt/centos-yum.bak/**

**\#各系统版本repo文件对应的下载操作**

**CentOS 6**

**wget -O /etc/yum.repos.d/CentOS6-Base-163.repo http://mirrors.163.com/.help/CentOS6-Base-163.repo**

**CentOS 7**

**wget -O /etc/yum.repos.d/CentOS7-Base-163.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo**

**阿里云的源：（[https://opsx.alibaba.com/mirror][https_opsx.alibaba.com_mirror]）--官方地址**

**CentOS 6**

**wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo**

**wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo**

**或者**

**curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo**

查看系统对应版本

**\[root@localhost ~\]\# cat /etc/redhat-release**
