Suse Linux系统的网卡冗余bonding新方法.doc

Suse Linux系统的网卡冗余bonding新方法以下介绍的Suse Linux系统对网卡的绑定方式，是Suse厂家提供的一种官方方法。特点的简便、适用，在运行过程中不易导致IP地址的丢失。在今后的开局过程中推荐使用该方法来对网口进行绑定。对网卡绑定的步骤如下：1，上传ifcfg-bond0到/etc/sysconfig/network 。ifcfg-bond0文件名是Suse启动网卡时，优先使用模式的配置文件BOOTPROTO=staticBROADCAST=192.168.132.191 ；根据现场情况修改IPADDR=192.168.132.172 ；根据现场情况修改MTU=NETMASK=255.255.255.224 ；根据现场情况修改NETWORK=192.168.132.160 ；根据现场情况修改REMOTE_IPADDR=STARTMODE=onbootBONDING_MASTER=yesBONDING_MODULE_OPTS=miimon=100 mode=1BONDING_SLAVE0=eth0BONDING_SLAVE1=eth12，YaST-网络设备-网卡。把需要绑定的网卡进行设定操作，完成设定操作后在/etc/sysconfig/network里就可以看到相关的ifcfg-eth-id-【mac】文件。如：ifcfg-eth-id-00:1e:0b:be:95:98对要绑定的网卡进行设定操作3，查看网卡配置信息的目录：wxmrc14:/etc/sysconfig/network # ls. if-up.d ifcfg-lo scripts. ifcfg-bond0 ifcfg.template update-logconfig ifcfg-eth-bus-pci-0000:0b:00.0 ifcfgeth0 update-log.debugdhcp ifcfg-eth-id-00:1e:0b:be:95:98 ifroute-lo wirelessif-down.d ifcfg-eth-id-00:1e:0b:be:95:9a providers4，两块网卡的启动模式修改为：none，目的是网卡启动时不使用DHCP模式。wxmrc14:/etc/sysconfig/network # vi ifcfg-eth-id-00:1e:0b:be:95:98BOOTPROTO=dhcp两块网卡均需要修改为：none，目的是网卡启动时不使用DHCP模式MTU=REMOTE_IPADDR=STARTMODE=onbootUNIQUE=Ddhb.sWQdX4kVaYC_nm_name=bus-pci-0000:05:00.05，再在/etc/init.d/network的start段的后面加上网关（SP03的补丁系统大约在462行）：route add default gw *.*.*.*（网关IP） 6，重启，使网卡配置生效。执行命令：/etc/init.d/network restart注意：这种模式bond的网卡，只有bond网卡上具备IP地址，而成员网卡上是没有IP地址的（我们一般使用的bond.sh脚本生成的bond网卡和成员网卡都具有相同的IP和MAC）wxmsc2: # ifconfigbond0 Link encap:Ethernet HWaddr 00:1C:C4:97:F6:EE inet addr:192.168.132.139 Bcast:192.168.132.159 Mask:255.255.255.224 inet6 addr: fe80:200:ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1 RX packets:11646558 errors:0 dropped:0 overruns:0 frame:0 TX packets:7301783 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1307158118 (1246.6 Mb) TX bytes:976959137 (931.7 Mb)bond0:0 Link encap:Ethernet HWaddr 00:1C:C4:97:F6:EE inet addr:192.168.132.152 Bcast:192.168.132.128 Mask:255.255.255.224 UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1eth0 Link encap:Ethernet HWaddr 00:1C:C4:97:F6:EE inet6 addr: fe80:21c:c4ff:fe97:f6ee/64 Scope:Link UP BROADCAST NOTRAILERS RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:11535817 errors:0 dropped:0 overruns:0 frame:0 TX packets:7301780 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1298141436 (1238.0 Mb) TX bytes:976958899 (931.7 Mb) Interrupt:20 Memory:fa000000-fa011100 eth1 Link encap:Ethernet HWaddr 00:1C:C4:97:F6:EE inet6 addr: fe80:21c:c4ff:fe97:f6ee/64 Scope:Link UP BROADCAST RUNNING NOARP SLAVE MULTICAST MTU:1500 Metric:1 RX packets:110741 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:9016682 (8.5 Mb) TX bytes:238 (238.0 b) Interrupt:21 Memory:f8000000-f8011100 eth2 Link encap:Ethernet HWaddr 00:18:71:EB:28:1E inet addr:10.10.132.32 Bcast:10.10.132.255 Mask:255.255.255.0 inet6 addr: fe80:218:71ff:feeb:281e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2544505 errors:0 dropped:0 overruns:0 frame:0 TX packets:2544519 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:223815010 (213.4 Mb) TX bytes:223816685 (213.4 Mb) Base address:0x6000 Memory:fdfe0000-fe000000 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:3736 error
