SUSE Linux双网卡绑定设置详解.doc

suse linux双网卡绑定设置详解双网卡的绑定可以实现冗余和高可用性，在suse linux 10中和redhat linux 5中设置双网卡绑定是不太一样的，下面详解一下suse linux 下的双网卡绑定：步骤1：进入到网络配置目录# cd /etc/sysconfig/network步骤2：创建ifcfg-bond0配置文件Vi ifcfg-bond0 输入如下内容保存BOOTPROTO=staticBROADCAST=IPADDR=172.27.120.21 #要绑定的ip地址NETMASK=255.255.255.0 #网段的掩码NETWORK=STARTMODE=onbootBONDING_MASTER=yesBONDING_MODULE_OPTS=mode=1 miimon=100 # mode=1是主备模式(active-backup) mode=0是平衡模式(balance_rr)BONDING_SLAVE0=eth0 #第一块网卡的mac地址BONDING_SLAVE1=eth1 #第二块网卡的mac地址ETHTOOL_OPTIONS=MTU=NAME=REMOTE_IPADDR=USERCONTROL=no步骤3：使用yast进入网卡的配置界面，把原有的两块网卡设置为没有ip，网卡模式改为自动获取地址模式，删除/etc/sysconfig/network下的已经绑定的网卡的配置文件步骤4：注意默认网关的配置，使用yast管理工具进入路由设置界面，或者通过修改配置文件的方式并运行命令进行配置配置默认网关。 # vi routes 插入如下内容default 172.27.120.254 - -# route add default gw 172.27.120.254步骤5：重启网络服务，使配置生效# rcnetwork restart步骤6：验证(1) 输入ifconfig可以看到bond0已经运行了,bond0、eth1、eth0的MAC地址都是一样JSBC-SIHUA-DB02:/etc/sysconfig/network # ifconfigbond0 Link encap:Ethernet HWaddr 78:2B:CB:4B:54:D5 inet addr:172.27.120.11 Bcast:172.27.120.255 Mask:255.255.255.0 inet6 addr: fe80:7a2b:cbff:fe4b:54d5/64 Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1 RX packets:93264981 errors:0 dropped:0 overruns:0 frame:0 TX packets:367528 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:16176230924 (15426.8 Mb) TX bytes:50574642 (48.2 Mb)eth0 Link encap:Ethernet HWaddr 78:2B:CB:4B:54:D5 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:46546840 errors:0 dropped:0 overruns:0 frame:0 TX packets:367528 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:8093090502 (7718.1 Mb) TX bytes:50574642 (48.2 Mb) Interrupt:34 Memory:f2000000-f2012800 eth1 Link encap:Ethernet HWaddr 78:2B:CB:4B:54:D5 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:46718141 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:8083140422 (7708.6 Mb) TX bytes:0 (0.0 b) Interrupt:44 Memory:f4000000-f4012800 (2) cat /proc/net/bonding/bond0看网卡工作状态，看到bond0,eth0,eth1都是正常的就ok 了。如果绑定不成功/proc/net/bonding/不会有bond0这个文件# cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.0.1 (January 9, 2006)Bonding Mode: fault-tolerance (active-backup)Primary Slave: NoneCurrently Active Slave: eth0MII Status: upMII Polling Interval (ms): 100Up Delay (ms): 0Down Delay (ms): 0Slave Interface: eth0MII Status: upLink Failure Count: 1Permanent HW addr: 78:2b:cb:53:dd:caSlave Interface: eth1MII Status: upLink Failure Count: 1Permanent HW addr: 78:2b:cb:53
