1. 搭建本地光盘YUM源
[[email protected] ~]# mkdir /mnt/cdrom/ ------》创建光盘挂载目录
[[email protected] ~]# mount /dev/cdrom /mnt/cdrom/ --------》挂在光盘
[[email protected] ~]# cd /etc/yum.repos.d/ --------》切换到YUM配置目录
[[email protected] yum.repos.d]# tar czf repo.tar.gz ./* --------》将原来所有的文件进行打包备份
[[email protected]yum yum.repos.d]# rm -f CentOS* --------》删除原文件
[[email protected] yum.repos.d]# vim CentOS-Media.repo --------》配置光盘源文件
[c6-media]
name=CentOS-$releasever - Media
baseurl=file:///mnt/cdrom --------》这里为你光盘的挂载目录
gpgcheck=1 --------》是否启动检查GPG-KEY
enabled=1 --------》是否启用YUM源
gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-CentOS-6 --》指定挂载目录下的GPG-KEY文件
验证：
2. 如果要让公司所有的Linux主机可用内部源服务，可以用FTP/HTTP搭建一个YUM服务器，由于Http较为简便，我这里就以HTTP的方式搭建一个YUM服务了。
继上面的操作，我借用本地光盘源搭建一个HTTP的YUM服务！
2.1
HTTP我在上面已经通过YUM的方式安装了，如果大家没有安装可以通过光盘里面的安装包进行安装，联网也可以通过网络的YUM进行安装。启动http服务！关闭防火墙和SELinux！
[[email protected] ~]# service httpd start
Starting httpd: httpd: apr_sockaddr_info_get() failed for yum.server [ OK ]
[[email protected] ~]# chkconfig httpd on
[[email protected] ~]# service iptables stop
[[email protected] ~]# chkconfig iptables off
[[email protected] ~]# setenforce 0
2.2
在Apache根目录下建立子文件夹，如果想让本YUM服务器为不同版本的Linux服务，可根据情况创建目录，然后将光盘内所有的文件CP至该目录！
注：一般使用DVD1即可，当然也可以合并DVD1和DVD2来作为源。
[[email protected] ~]# mkdir -p /var/www/html/yum
[[email protected] ~]# mkdir -p /var/www/html/yum/CentOS-6
[[email protected] ~]# cp -prf /mnt/cdrom/* /var/www/html/yum/CentOS-6/
2.3
客户端修改CentOS-Base.repo，建议先备份一个副本哦，这样以后要从外网更新的话，可以再用。
[[email protected] yum.repos.d]# cp CentOS-Base.repo CentOS-Base.repo.bak1
[[email protected] yum.repos.d]# vim CentOS-Base.repo
###################CentOS-Base.repo内容修改后，如下#####################

centosplus][contrib]的内容不需要修改，它们的enabled值默认值是0，即模块不启用。

客户端测试！
附加：
DVD1和DVD2文件合并的步骤：
1.将DVD2光盘中Packages目录下所有的rpm文件CP到DVD1的目录下。
Cp /mnt/dvd2/Packages/*.rpm /var/www/html/yum/CentOS-6/Packages/
2.合并TRANS.TBL，将DVD2中TRANS.TBL的信息追加到DVD1中TRANS.TBL后面, 并排序保存。
cat mnt/dvd2/Packages/TRANS.TBL >> /var/www/html/yum/centos-6/Packages/TRANS.TBL
Mv /var/www/html/yum/centos-6/Packages/{TRANS.TBL,TRANS.TBL.BAK}
Sort /var/www/html/yum/centos-6/Packages/TRANS.TBL.BAK/var/www/html/yum/centos-6/Packages/TRANS.TBL
