linux多网卡绑定

linux多网卡绑定 Linux多网卡绑定一个IP教程 例如:网卡1为eth0 网卡2为eth1 1.先修改eth0 和eht1这2个网卡配置文件.目录在(/etc/sysconfig/network-scripts/)如下: DEVICE=eth0 ONBOOT=yes MASTER=bond0 BOOTPROTO=none 2. eth1 也是同样的修改.如下: DEVICE=eth1 ONBOOT=yes MASTER=bond0 BOOTPROTO=none 3.新建一个虚拟网卡bond0,我们可以复制eth0的,复制后要修改. 复制 (cp /etc/sysconfig/network-scripts/ifcfg-eth0 ifcfg-bond0)修改内容为如下: DEVICE=bond0 ONBOOT=yes BOOTPROTO=static IPADDR=192.168.0.227 NETMASK=255.255.255.0 BROADCAST=192.168.0.255 TYPE=Ethernet 4.修改/etc/modprobe.conf,添加内容如下: alias bond0 bonding options bond0 miimon=100 mode=6 注意:mode可以为0, 1, 0为负载均衡,1为失效保护, 我们只用到0 关于:modprobe.conf文件在AS版本里面有，linux9.0的是这个modules.conf文件 5:修改/etc/rc.d/rc.local,添加内容如下: ifenslave bond0 eth0 eth1 route add -net 192.168.0.255 netmask 255.255.255.0 bond0 完成。。。。。。。。。。。 查看: [root@LMsev ~]# cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.0.3 (March 23, 2006) Bonding Mode: fault-tolerance (active-backup) Primary Slave: None Currently Active Slave: eth0 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eth0 MII Status: up Link Failure Count: 0 Permanent HW addr: 00:0c:29:ea:73:0f Slave Interface: eth1 MII Status: up Link Failure Count: 0 Permanent HW addr: 00:0c:29:ea:73:19
