Centos6 克隆后简单的网络配置
第一步：修改主机名
$ vi /etc/sysconfig/network
第二步：
$ vi /etc/udev/rules.d/70-persistent-net.rules
注：
①注释掉第一网卡驱动红色标注地方
②修改第二个网卡驱动name=“eth0”
# PCI device 0x1022:0x2000 (pcnet32)
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:ac:0c:#39", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:95:4a:d3", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" 第三步： $ vi /etc/sysconfig/network-scripts/ifcfg-eth0 删除UUID,HWADRR 修改
