搭建本地yum服务器
在内网环境下，服务器通常不联网，这时候如果要下载什么软件，搭建本地yum服务器的话就很方便了。
创建挂载目录：
[root@Herry ~]# mkdir -p /local/yum
2.挂载你的光盘或者U盘到指定目录下，这里的/dev/cdrom可以是你的U盘，具体看你用什么了[root@Herry ~]# mount /dev/cdrom /local/yum
3.copy源yum的目录文件，我做实验需要还原的，这个不是必须
[root@Herry ~]# cp -r /etc/yum.repos.d /etc/yum.repos.d.aak
4.删除源Yum目录下的所有文件，这个不是必须
[root@Herry ~]# rm -f /etc/yum.repos.d/*
5.修改配置文件，你也可以直接在/etc/yum.repos.d/CentOS-Base.repo下增加以下配置，不过在使用yum的时候，它会从上往下匹配，比较耗时，所以这里我就直接删除源yum文件了，新增了以下local_yum.repo：
[root@Herry ~]# vim /etc/yum.repos.d/local_yum.repo
[local_yum]
name=this is local yum
baseurl=file:///local/yum
enabled=1 （是否启用该yum源，0为禁用）
gpgcheck=0 （是否检查gpgkey，0为不检查）
#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6（gpgcheck=0时无需配置）
6.测试：卸载vim
[root@Herry ~]# yum remove -y vim
Loaded plugins: fastestmirror

There are unfinished transactions remaining. You might consider running yum-complete-transaction first to finish them.
The program yum-complete-transaction is found in the yum-utils package.

7.命令vim无法使用了：
[root@Herry ~]# !v
vim /etc/yum.repos.d/local_yum.repo
-bash: /usr/bin/vim: 没有那个文件或目录
8.安装回来vim:
[root@Herry ~]# yum install -y vim
Loaded plugins: fastestmirror

9.可以使用vim了 ：
[root@Herry ~]# !v
vim /etc/yum.repos.d/local_yum.repo
[local_yum]
name=this is local yum
baseurl=file:///local/yum
enabled=1
gpgcheck=0
至此本地yum搭建完成。
