一、源列表

aliyun源

#各系统版本repo文件对应的下载操作
CentOS
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
CentOS
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
CentOS
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

163源

#各系统版本repo文件对应的下载操作
CentOS
wget -O /etc/yum.repos.d/CentOS5-Base-.repo http://mirrors.163.com/.help/CentOS5-Base-163.repo
CentOS
wget -O /etc/yum.repos.d/CentOS6-Base-.repo http://mirrors.163.com/.help/CentOS6-Base-163.repo
CentOS
wget -O /etc/yum.repos.d/CentOS7-Base-.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo

二、配置源

我用的是CentOS 7，以163源为例，操作如下：

[lz@mail lcap-0.0.]$ cat /etc/redhat-release
CentOS Linux release 7.3. (Core)
[lz@mail lcap-0.0.]$ sudo wget -O /etc/yum.repos.d/CentOS7-Base-.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo
[sudo] password for lz:
---- ::-- http://mirrors.163.com/.help/CentOS7-Base-163.repo
正在解析主机 mirrors..com (mirrors..com)... 59.111.0.251
正在连接 mirrors..com (mirrors..com)|59.111.0.251|:... 已连接。
已发出 HTTP 请求，正在等待回应... OK

正在保存至: “/etc/yum.repos.d/CentOS7-Base-.repo”%[=========================================================================================================================================================================>] , --.-K/s 用时 0s -- :: (89.9 MB/s) - 已保存 “/etc/yum.repos.d/CentOS7-Base-.repo” [/])

三、源缓存

Step 1 : 清除旧的源缓存：

[lz@mail lcap-0.0.]$ yum clean all
已加载插件：fastestmirror, langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration
Repodata is over weeks old. Install yum-cron? Or run: yum makecache fast
正在清理软件源： base epel extras mysql-connectors-community mysql-tools-community mysql56-community updates
Cleaning up everything

Step 2 : 构建新的源缓存：（只展示一部分）

[lz@mail lcap-0.0.]$ yum makecache
已加载插件：fastestmirror, langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration
Repodata is over weeks old. Install yum-cron? Or run: yum makecache fast
