Foreword:
Since most of the company's business runs in an intranet environment, the intranet environment cannot directly use yum to install, upgrade and update software, so it is necessary to build a self-built Yum source to meet the current daily work needs.
Download all installation packages in the entire Yum source to the local specified directory
1. Prepare to download to the local Yum source (Alibaba source, Tsinghua source)
2. Check Yum source status
[root@centos ~]# yum repolist
已加载插件：fastestmirror
Loading mirror speeds from cached hostfile
仓库标识 仓库名称 状态
extras Qcloud centos extras - x86_64 47
os Qcloud centos os - x86_64 6,713
updates Qcloud centos updates - x86_64 1,169
repolist: 7,929
You can see that there are three warehouses in the Yum source we prepared, with a total of 7929 installation packages.
3. Download all installation packages in the entire Yum source to the local server
reposync：This command is very powerful and can download all installation packages in the remote Yum repository to the local directory.该命令是来自于 yum-utils 软件包里面的。
Description of common parameters:
-r: Specify the name of the repo source of the locally configured yum warehouse
-p: Specify the download path
[root@centos ~]# yum -y install yum-utils #执行安装软件包
[root@centos ~]# mkdir centos6 #创建本地Yum包存放目录
[root@centos ~]# yum repolist #查看Yum源的仓库标识名称

You can see that there are three folders in the local centos6 directory. These three folders represent the three warehouses in the Yum source we downloaded. Each warehouse has different installation packages. With all the installation packages of the entire Yum source, follow Next we can use them to build our own Yum source.
