Suse Linux系统的网卡冗余bonding新方法

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

卡时，优先使用模式的配置文件

。ifcfg-bond0文件名是Suse启动网

2，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

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-log

config ifcfg-eth-bus-pci-0000:0b:00.0 ifcfgeth0 update-log.debug dhcp ifcfg-eth-id-00:1e:0b:be:95:98 ifroute-lo wireless

if-down.d ifcfg-eth-id-00:1e:0b:be:95:9a providers

4，两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\:98

BOOTPROTO='dhcp'

MTU=''

REMOTE_IPADDR=''

STARTMODE='onboot'

UNIQUE='Ddhb.sWQdX4kVaYC'

_nm_name='bus-pci-0000:05:00.0'

5，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

意： 注

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）
