1、修改主机名

#hostname lvs1

#vim /etc/sysconfig/network

    NETWORKING = yes    

    HOSTNAME = lvs1  

2、修改mac地址

#vim  /etc/udev/rules.d/70-persistent-net.rules

# PCI device 0x8086:0x100f (e1000)
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:02:b6:9b", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:03:4c:9e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

把上一行注销掉，然后把下面这个改为eth0

然后#vim /etc/sysconfig/network-scripts/ifcfg-eth0 
DEVICE=eth0
HWADDR=00:0c:29:03:4c:9e
TYPE=Ethernet
UUID=51a3aab4-42cc-4e9a-b5d6-e23bb16c2b54
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp

3、重新启动网卡 #service network restart

4、 #ifconfig
          eth0      Link encap:Ethernet  HWaddr 00:0c:29:03:4c:9e 
          inet addr:192.168.213.136  Bcast:192.168.213.255  Mask:255.255.255.0
