linux —仓库搭建 yum实验
一：安装httpd安装包
[root@localhost ~]# yum -y install httpd ###安装httpd

二：离线状态下安装rpm软件包
2.1：模拟无网络
把虚拟机网络切换到仅主机模式，这样虚拟机只能跟宿主机通信，无法访问外网

总结：名称中不能有空格
yum仓库搭建四要素
[]
name = 仓库名称 名称
baseurl =file://+路径 仓库软件源
enabled=1 1 开启yum仓库 0是关闭
gpgback=0 关闭密钥检查

四：测试yum仓库安装
先卸载之前安装的httpd软件，重新用搭建的本地yum仓安装
[root@localhost Packages]# yum remove httpd
[root@localhost yum.repos.d]# yum -y install httpd

用搭建的本地yum仓安装
[root@localhost Packages]# yum remove httpd
[root@localhost yum.repos.d]# yum -y install httpd
