第一步:配置网关 dns
第二步:打开CRT 安装bind
在Mnt下面创建文件夹cdrom。
[ root@localhost ~]# mkdir /mnt/cdrom
将光盘挂载到CD ROM的文件夹下。 [root@localhost ~]# mount /dev/cdrom /mnt/cdrom mount: /dev/sr0 写保护,将以只读方式挂载
进入源文件。 [root@localhost ~]# cd /etc/yum.repos.d/
删除所有文件。 [root@localhost yum.repos.d]# rm -rf * 编辑新文件。 [root@localhost yum.repos.d]# vim dvd.repo ### 这是本地源安装
编辑内容为。 [dvd] name=dvd baseurl=file:///mnt/cdrom enabled=1 gpgcheck=0 编辑完保存退出。 清除缓存。
[root@localhost yum.repos.d]# yum clean all 生成缓存。 [root@localhost yum.repos.d]# yum makecache 安装DNS服务 [root@localhost yum.repos.d]# yum -y install bind
