1背景
由于客户环境只有局域网，没法使用网上的各种YUM源，来回拷贝rpm包安装麻烦，还得解决依赖问题。想着在CentOS7.2搭建个本地/局域网YUM源，方便自己跟同事安装软件。
2环境
[root@linuxidc.com ~]# cat /etc/RedHat-release CentOS Linux release 7.2.1511 (Core)
3安装
3.1本地YUM源
3.1.1 ISO源
@H_403_18@ 准备rpm包 @H_403_18@ 挂载CentOS-7-x86_64-Everything-1511.iso，把里面所有文件都拷贝到本地目录/yum/yum-isomkdir /mnt/yum-iso
[root@linuxidc.com ~]# mount /dev/cdrom /mnt/yum-iso/
mount: /dev/sr0 is write-protected,mounting read-only
[root@linuxidc.com ~]# mkdir /yum/
[root@linuxidc.com ~]# cp -a /mnt/yum-iso/ /
[root@linuxidc.com ~]# ll /
