linux修改網路卡名字

ifconfig發現網路卡名字(eth1、eth2)與配置檔案中名字(eth0、eth1)不符，修改如下
一、檢視網路卡名字對應的HWADDR
[root@linnux ~]# ifconfig -a
eth1      Link encap:Ethernet  HWaddr 08:00:27:14:87:06
          inet addr:192.168.1.2  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::a00:27ff:fe14:8706/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:658 errors:0 dropped:0 overruns:0 frame:0
          TX packets:527 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:65027 (63.5 KiB)  TX bytes:78666 (76.8 KiB)


eth2      Link encap:Ethernet  HWaddr 08:00:27:3E:94:DC
          inet addr:172.168.1.2  Bcast:172.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::a00:27ff:fe3e:94dc/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:35 errors:0 dropped:0 overruns:0 frame:0
          TX packets:37 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:5599 (5.4 KiB)  TX bytes:7155 (6.9 KiB)


二、編輯ifcfg-eth0檔案和ifcfg-eth1檔案，把MAC改為正確的，把UUID刪掉
[root@node1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.1.2
PREFIX=24
GATEWAY=192.168.1.1
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="eth0"
#UUID=1976d3c7-b6fa-4002-8738-f370de6eddd6
ONBOOT=yes
HWADDR=08:00:27:14:87:06
LAST_CONNECT=1498051708


三、檢視檔案70-persistent-net.rules進行修改，網路卡名字要和MAC地址對應
[root@node1 ~]# cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.


# PCI device 0x8086:0x100e (e1000)
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:41:05:c4", ATTR{type}=="1"                                   , KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x100e (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:14:87:06", ATTR{type}=="1",                                    KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x100e (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:3e:94:dc", ATTR{type}=="1",                                    KERNEL=="eth*", NAME="eth1"

四、檢視hostname是否正確
[root@node1 ~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=node1
