进入IP配置目录 cd /etc/sysconfig/network-scripts使用vi工具，修改ifcfg-eth0 的ONBOOT选项为yes ONBOOT=yes使用命令，重启网络 service network restart使用ifconfig 命令，即可查看ip，如下： [root@centos67 network-scripts]# ifconfig 查看结果

5.记下HWaddr，然后修改ifcfg-eth0文件，内如如下：
DEVICE=eth0
HWADDR=00:0C:29:F4:03:D0
TYPE=Ethernet
UUID=359cd620-b257-482f-931d-59d618e8064c
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=192.168.0.128
NETWORK=255.255.255.0
GATEWAY=192.168.0.2
DNS1=192.168.0.2
6.修改/etc/hosts （一个主节点和三个子节点） 192.168.128.130 master master.centos.com 192.168.128.131 slave1 slave1.centos.com 192.168.128.132 slave2 slave2.centos.com 192.168.128.133 slave3 slave3.centos.com
