1、切换到root用户

2、ifconfig 查看当前ip

\[root@node2 network-scripts\]\# ifconfig  
eth2      Link encap:Ethernet  HWaddr 00:0C:29:E8:43:86    
          inet addr:192.168.204.152  Bcast:192.168.204.255  Mask:255.255.255.0  
          inet6 addr: fe80::20c:29ff:fee8:4386/64 Scope:Link  
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1  
          RX packets:391628 errors:0 dropped:0 overruns:0 frame:0  
          TX packets:585359 errors:0 dropped:0 overruns:0 carrier:0  
          collisions:0 txqueuelen:1000   
          RX bytes:31849934 (30.3 MiB)  TX bytes:72930434 (69.5 MiB)

lo        Link encap:Local Loopback    
          inet addr:127.0.0.1  Mask:255.0.0.0  
          inet6 addr: ::1/128 Scope:Host  
          UP LOOPBACK RUNNING  MTU:65536  Metric:1  
          RX packets:12871 errors:0 dropped:0 overruns:0 frame:0  
          TX packets:12871 errors:0 dropped:0 overruns:0 carrier:0  
          collisions:0 txqueuelen:0   
          RX bytes:1331981 (1.2 MiB)  TX bytes:1331981 (1.2 MiB)

3、cd  /etc/sysconfig/network-scripts  
4、ls  
\[root@node2 network-scripts\]\# ls  
ifcfg-eth0   ifdown-ipv6    ifup          ifup-isdn    ifup-tunnel  
ifcfg-lo     ifdown-isdn    ifup-aliases  ifup-plip    ifup-wireless  
ifdown       ifdown-post    ifup-bnep     ifup-plusb   init.ipv6-global  
ifdown-bnep  ifdown-ppp     ifup-eth      ifup-post    net.hotplug  
ifdown-eth   ifdown-routes  ifup-ib       ifup-ppp     network-functions  
ifdown-ib    ifdown-sit     ifup-ippp     ifup-routes  network-functions-ipv6  
ifdown-ippp  ifdown-tunnel  ifup-ipv6     ifup-sit

5、如果没有对应的配置文件，可以cp ifcfg-eth0 ifcfg-eth2   
6、vi ifcfg-eth2    
主要内容：（HWADDR自己查看虚拟机分配的mac）  
DEVICE="eth2"  
HWADDR="00:0C:29:E8:43:86"  
IPADDR=192.168.204.148  
NETMASK=255.255.255.0  
BOOTPROTO="static"  
GATEWAY="192.168.204.2"      \#网关 ，个人没有配置  
DNS="192.168.204.1" \#DNS服务器 ，个人没有配置

7、service network restart
