Redhat安装见上一篇：VMware Workstation安装Redhat6.4全过程附图（一）
本篇主要讲虚拟机网络配置以及如何跳过yum收费问题。
虚拟机安装后，我们输入ping自己的宿主机IP172.168.43.41，会提示Network is unreachable。
输入ifconfig命令，发现并没有eth0网卡信息。
编辑网络配置文件：vi /etc/sysconfig/network-scripts/ifcfg-eth0，修改如下
配置项说明，例子而已。
DEVICE=eth0 #网卡设备名称 ONBOOT=yes #启动时是否激活 yes | no BOOTPROTO=static #协议类型 IPADDR=192.168.1.90 #网络IP地址 NETMASK=255.255.255.0 #网络子网地址 GATEWAY=192.168.1.1 #网关地址 BROADCAST=192.168.1.255 #广播地址 HWADDR=00:0C:29:FE:1A:09 #网卡MAC地址 TYPE=Ethernet #网卡类型为以太网
重启网卡：service network restart
再次输入ifconfig命令，可以看到eth0网卡信息了。
从虚拟机ping宿主机，从宿主机ping虚拟机，都通啦。
从虚拟机ping百度，也没有问题
现在尝试安装lrzsz命令，运行命令yum -y install lrzsz。
报错This system is not registered。要解决这个问题，只能把redhat自带yum卸载，然后用centos源的yum命令。
1、进入/usr/local目录，创建一个soft文件夹，将安装yum所需要的包下载到soft文件夹下。
wget https://vault.centos.org/6.5/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm wget https://vault.centos.org/6.5/os/x86_64/Packages/python-urlgrabber-3.9.1-9.el6.noarch.rpm wget https://vault.centos.org/6.5/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpm wget https://vault.centos.org/6.5/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm wget https://vault.centos.org/6.5/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
2、查看原来是否安装yum： rpm -qa |grep yum
3、直接卸载自带的yum： rpm -qa|grep yum|xargs rpm -e --nodeps
4、查看是否卸载干净： rpm -qa |grep yum
5、依次安装之前下载的5个rpm文件
rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm rpm -ivh python-urlgrabber-3.9.1-9.el6.noarch.rpm rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm --force --nodeps rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm rpm -ivh yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm --force --nodeps
6、更换yum源。使用163的源
进入/etc/yum.repos.d/目录，把rhel-source.repo文件备份一份
备份命令：cp rhel-source.repo rhel-source.repo.bak
执行vi rhel-source.repo命令，替换文件内容为：
# 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. # # [base] name=CentOS-6.7 - Base - 163.com baseurl=https://vault.centos.org/centos/6.7/os/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6.7&arch=$basearch&repo=os gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #released updates [updates] name=CentOS-6.7 - Updates - 163.com baseurl=https://vault.centos.org/centos/6.7/updates/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6.7&arch=$basearch&repo=updates gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #additional packages that may be useful [extras] name=CentOS-6.7 - Extras - 163.com baseurl=https://vault.centos.org/centos/6.7/extras/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6.7&arch=$basearch&repo=extras gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-6.7 - Plus - 163.com baseurl=https://vault.centos.org/centos/6.7/centosplus/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6.7&arch=$basearch&repo=centosplus gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #contrib - packages by Centos Users [contrib] name=CentOS-6.7 - Contrib - 163.com baseurl=https://vault.centos.org/centos/6.7/contrib/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6.7&arch=$basearch&repo=contrib gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
7、清除缓存： yum clean all
运行yum clean all时报如下错误：
这时我们只需要把subscription-manager命令卸载即可
查看subscription-manager版本： rpm -qa | grep subscription-manager
卸载subscription-manager：rpm -e subscription-manager-1.1.23-1.el6.x86_64
卸载之后再次执行yum clean all
8、测试，再次安装rzsz命令：yum -y install lrzsz，执行成功。
9、建立元数据缓存：yum makecache
到此RedHat安装结束。
