1、dmesg |grep -i eth
ethtool -i eth1
[root@centos6 ~]# dmesg |grep -i eth e1000 0000:02:01.0: eth0: (PCI:66MHz:32-bit) 00:50:56:3f:3f:87 e1000 0000:02:01.0: eth0: Intel(R) PRO/1000 Network Connection e1000 0000:02:05.0: eth1: (PCI:66MHz:32-bit) 00:50:56:25:24:c8 e1000 0000:02:05.0: eth1: Intel(R) PRO/1000 Network Connection
卸載網卡驅動：modprobe -r e1000
裝載網卡驅動：modprobe e1000
2、編輯 /etc/udev/rules.d/70-persistent-net.rules #注意mac 地址
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:25:24:c8", ATTR{type}=
="1", KERNEL=="eth*", NAME="eth1"
# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:3f:3f:87", ATTR{type}=
="1", KERNEL=="eth*", NAME="eth0"
3、編輯靜態網卡：/etc/sysconfig/network-scripts
[root@centos6 network-scripts]# vim ifcfg-eth0 TYPE=Ethernet BOOTPROTO=static DEFROUTE=yes PEERDNS=yes PEERROUTES=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no NAME=eth0 DEVICE=eth0 ONBOOT=yes IPADDR=192.168.30.104 GATEWAY=192.168.30.1 DNS1=192.168.30.1
4、編輯動態網卡：/etc/sysconfig/network-scripts
[root@centos6 network-scripts]# vim ifcfg-eth1 TYPE=Ethernet #BOOTPROTO=static BOOTPROTO=dhcp DEFROUTE=yes PEERDNS=yes PEERROUTES=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no NAME=eth1 DEVICE=eth1 ONBOOT=yes
5、reboot/init 6
6、驗證結果：
7、腳本轉載：
