###########在server主机中配置yum仓库，并安装gcc编辑器
利用真实主机共享yum源给server主机，以节省server主机空间
1.####在真实主机中配置yum源共享
[root@foundation37 Desktop]# cd /mnt
[root@foundation37 mnt]# ls
guazai rhel-server-7.1-x86_64-dvd.iso
LENOVO_GhostXP_SP3_2014.04.iso wps-office-8.1.0.3724-0.1.b1p2.i686.rpm
[root@foundation37 mnt]# mount /mnt/rhel-server-7.1-x86_64-dvd.iso /mnt/guazai ###把镜像挂载到/mnt/guazai目录下
mount: /dev/loop0 is write-protected, mounting read-only
[root@foundation37 mnt]# vim /etc/yum.repos.d/yum.repo ####编辑yum指向文件
[root@foundation37 mnt]# yum clean all ####更新yum指向

[root@foundation37 mnt]# umount /mnt/rhel-server-7.1-x86_64-dvd.iso ####解除镜像挂载
[root@foundation37 mnt]# mount /mnt/rhel-server-7.1-x86_64-dvd.iso /var/www/html/rhel7.1/ ###挂载镜像到httpd服务共享目录
mount: /dev/loop0 is write-protected, mounting read-only
在yum源存放主机中用浏览器输入http://本机ip/rhel7.1 ######测试共享是否成功
已共享成功
2.########server主机中
[root@server Desktop]# rm -fr /etc/yum.repos.d/yum.repo ####清除以前yum指向文件
[root@server Desktop]# vim /etc/yum.repos.d/yum.repo #####配置主机yum指向
[root@server Desktop]# yum clean all ###更新yum指向
