实现私有 yum 仓库搭建

前提：必须是同一系统，可以是不同版本。

IP	角色
192.168.61.136	yum server
192.168.61.141	client

步骤：

        1. 在 yum server 机上搭建 web 服务，保证其它机器能能过web服务访问本机

        2. 在 yum server 机上搭建 yum 仓服务

        3. 在 client 机上将yum 的 repos 源指向 yum server 机

        4. 测试

服务端配置

#安装wed服务
[root@rocky-136 yum.repos.d]#systemctl status firewalld.service#关闭防火墙
[root@rocky-136 yum.repos.d]#systemctl disable --now firewalld.service
Removed "/etc/systemd/system/multi-user.target.wants/firewalld.service".
Removed "/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service".#开启web服务
[root@rocky-136 ~]#systemctl enable --now httpd
Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service → /usr/lib/systemd/system/httpd.service.
