一、网络安装yum 源软件

# CentOS-Base.repo

#

# The mirror system uses the connecting IP address of the client and the

# update status of each mirror to pick mirrors that are updated to and

# geographically close to the client.  You should use this for CentOS updates

# unless you are manually picking other mirrors.

#

# If the mirrorlist= does not work for you, as a fall back you can try the

# remarked out baseurl= line instead.

二、本地挂载光盘安装yum

1. 创建挂载光驱文件的目录

   mkdir  /root/zzx

2. 配置yum源文件

   vim  /etc/yum.repos.d/yum.repo

   添加如下内容

   [base]

   name=Server

   baseurl=file:///root/zzx/Server

   enabled=1

   [VT]

   name=VT

   baseurl=file:///root/zzx/VT

   enabled=1

   [Cluster]

   name=Server

   baseurl=file:///root/zzx/Cluster

   enabled=1

   [ClusterStorage]

   name=Server

   baseurl=file:///root/zzx/ClusterStorage

   enabled=1

3. 挂载光驱

   umount -a  清除挂载点

   mount /dev/cdrom /root/zzx

4. 常见的错误几点

   提示：

   Downloading Packages:

   warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 37017186

   解决方法：rpm --import /etc/pki/rpm-gpg/RPM*

5. 同过yum安装软件

   yum install httpd -y

   yum clean all //清理节点
