SUSE Linux 10 下重命名网卡名字

前阵子碰到suse linux下网卡重命名的问题，是在虚拟机上安装RAC，通过复制虚拟机后需要完成的。与redhat linux，以及oralce linux不同的处理方式，下面将其记录下来，供参考。1、新节点的网络配置#启动节点之后没有任何IP配置信息bo2dbp:~ # ifconfigloLink encap:Local Loopback

前阵子碰到suse linux下网卡重命名的问题，是在虚拟机上安装RAC，通过复制虚拟机后需要完成的。与redhat linux，以及oralce linux不同的处理方式，下面将其记录下来，供参考。

1、新节点的网络配置 
#启动节点之后没有任何IP配置信息   
 bo2dbp:~ # ifconfig
 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:16436  Metric:1
           RX packets:174 errors:0 dropped:0 overruns:0 frame:0
           TX packets:174 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:0
           RX bytes:11471 (11.2 Kb)  TX bytes:11471 (11.2 Kb)

2、使用yast2/newcard删除之前的网卡，并为新网卡添加IP地址，路由，机器名   
    #下面是删除后并配置ip,route之后的信息   
 bo2dbp:~ # ifconfig
 eth3      Link encap:Ethernet  HWaddr 00:0C:29:99:DF:0F
           inet addr:192.168.7.71  Bcast:192.168.7.255  Mask:255.255.255.0
           inet6 addr: fe80::20c:29ff:fe99:df0f/64 Scope:Link
           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
           RX packets:10 errors:0 dropped:0 overruns:0 frame:0
           TX packets:4 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:1000
           RX bytes:2387 (2.3 Kb)  TX bytes:328 (328.0 b)
 
 eth4      Link encap:Ethernet  HWaddr 00:0C:29:99:DF:19
           inet addr:10.10.7.71  Bcast:10.10.7.255  Mask:255.255.255.0
           inet6 addr: fe80::20c:29ff:fe99:df19/64 Scope:Link
           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
           RX packets:7 errors:0 dropped:0 overruns:0 frame:0
           TX packets:3 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:1000
           RX bytes:1607 (1.5 Kb)  TX bytes:238 (238.0 b)
 
 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:16436  Metric:1
           RX packets:206 errors:0 dropped:0 overruns:0 frame:0
           TX packets:206 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:0
           RX bytes:13803 (13.4 Kb)  TX bytes:13803 (13.4 Kb)

3、停用网路
 bo2dbp:~ # rcnetwork stop
 Shutting down network interfaces:
     eth3      device: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01)
     eth3      configuration: eth-bus-pci-0000:02:00.0
     eth3                                                              done
     eth4      device: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01)
     eth4      configuration: eth-bus-pci-0000:02:02.0
     eth4                                                              done
 Shutting down service network  .  .  .  .  .  .  .  .  .  .  .  .  .  done

4、编辑配置文件
 #将原来的eth0 与 eth1注释掉
 #并将新的mac地址条目改为eth0与eth1
 bo2dbp:~ # vi /etc/udev/rules.d/30-net_persistent_names.rules
 
 #SUBSYSTEM=="net", ACTION=="add", SYSFS{address}=="00:0c:29:8a:6c:c8", IMPORT="/lib/udev/rename_netiface %k eth0"
 #SUBSYSTEM=="net", ACTION=="add", SYSFS{address}=="00:0c:29:8a:6c:d2", IMPORT="/lib/udev/rename_netiface %k eth1"
 SUBSYSTEM=="net", ACTION=="add", SYSFS{address}=="00:0c:29:99:df:0f", IMPORT="/lib/udev/rename_netiface %k eth0"
 SUBSYSTEM=="net", ACTION=="add", SYSFS{address}=="00:0c:29:99:df:19", IMPORT="/lib/udev/rename_netiface %k eth1"

5、使用rename_netiface命令重命名网络接口
 bo2dbp:~ # cd /lib/udev
 bo2dbp:/lib/udev # ./rename_netiface eth3 eth0
 INTERFACE=eth0
 DEVPATH=/eth0
 RENAMED=yes
 bo2dbp:/lib/udev # ./rename_netiface eth4 eth1
 INTERFACE=eth1
 DEVPATH=/eth1
 RENAMED=yes

6、重启网络
 bo2dbp:/lib/udev # rcnetwork start
 Hint: you may set mandatory devices in /etc/sysconfig/network/config
 Setting up network interfaces:
     lo
     lo        IP address: 127.0.0.1/8
               IP address: 127.0.0.2/8
 Checking for network time protocol daemon (NTPD):                     unused
     lo                                                                done
     eth0      device: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01)
     eth0      configuration: eth-bus-pci-0000:02:00.0
     eth0      IP address: 192.168.7.71/24
 Checking for network time protocol daemon (NTPD):                     unused
     eth0                                                              done
     eth1      device: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01)
     eth1      configuration: eth-bus-pci-0000:02:02.0
     eth1      IP address: 10.10.7.71/24
 Checking for network time protocol daemon (NTPD):                     unused
     eth1                                                              done
 Setting up service network  .  .  .  .  .  .  .  .  .  .  .  .  .  .  done

7、检查结果
 bo2dbp:/lib/udev # ifconfig
 eth0      Link encap:Ethernet  HWaddr 00:0C:29:99:DF:0F
           inet addr:192.168.7.71  Bcast:192.168.7.255  Mask:255.255.255.0
           inet6 addr: fe80::20c:29ff:fe99:df0f/64 Scope:Link
           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
           RX packets:754 errors:0 dropped:0 overruns:0 frame:0
           TX packets:12 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:1000
           RX bytes:136187 (132.9 Kb)  TX bytes:936 (936.0 b)
 
 eth1      Link encap:Ethernet  HWaddr 00:0C:29:99:DF:19
           inet addr:10.10.7.71  Bcast:10.10.7.255  Mask:255.255.255.0
           inet6 addr: fe80::20c:29ff:fe99:df19/64 Scope:Link
           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
           RX packets:752 errors:0 dropped:0 overruns:0 frame:0
           TX packets:12 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:1000
           RX bytes:136065 (132.8 Kb)  TX bytes:936 (936.0 b)
 
 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:16436  Metric:1
           RX packets:206 errors:0 dropped:0 overruns:0 frame:0
           TX packets:206 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:0
           RX bytes:13803 (13.4 Kb)  TX bytes:13803 (13.4 Kb)

  事实上，我们可以根据上述方法来将网卡设定为有意义的接口名字，如lan0,lan1,public0,public1。
