服务器评测
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。
