Bonding技术
以下内容适用于：
MiracleLinux （2.4.21-9.38AXsmp）
TurboLinux Server（2.4.18-5smp和2.4.18-22smp）
Red Hat Enterprise Linux AS 3（Kernel 2.4.21-4）
/etc/modules.conf文件
alias bond0 bonding
alias bond1 bonding
options bond0 –o bond0 mode=0 miimon=100
options bond1 –o bond1 mode=1 miimon=200
/etc/sysconfig/network-scripts目录
Ifcfg-bond0 ifcfg-bond1两个文件
Ifcfg-eth0 ifcfg-eth1两个文件
# ifcfg-bond1文件内容

# ifcfg-eth1文件内容

[root@xxx root]# cat /proc/net/bond1/info

系统加载bonding模块后执行lsmod命令结果：
[root@xxx root]# lsmod | sort

以下内容适用于Suse 9 (Kernel 2.6) [特殊]
只需要创建文件/etc/sysconfig/network/ifcfg-bond0即可，内容如下：
# suse 9 kernel 2.6 ifcfg-bond0文件内容
BOOTPROTO='static'
IPADDR='192.168.0.1'
NETMASK='255.255.255.0'
STARTMODE='onboot'
BONDING_MASTER='yes'
BONDING_MODULE_OPTS='mode=1 miimon=200'
BONDING_SLAVE0='eth1'
BONDING_SLAVE1='eth2'
对于其它的Linux，内核版本2.6以上
[和标准2.4一样]
需要将alias和options从/etc/modules.conf转移到/etc/modprobe.conf即可。
另/proc/net/bond0/info文件变更为/proc/net/bonding/bond0文件中
以下内容适用于Turbolinux Enterprise Server 8 powered by UnitedLinux Kernel 2.4.21-241xxx，
Ifcfg-bond0等文件存放在/etc/sysconfig/network/目录下
例： [来源于HP技术支持网站]
United Linux 1.0/SuSE8
#vi /etc/modules.conf
alias bond0 bonding
options bond0 miimon=100 mode=1
#vi /etc/sysconfig/network/ifcfg-bond0
DEVICE=bond0
IPADDR=192.168.10.1
NETMASK=255.255.255.0
NETWORK=192.168.10.0
BROADCAST=192.168.10.255
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
#vi /etc/sysconfig/network/ifcfg-eth0
DEVICE=eth0
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none
#vi /etc/sysconfig/network/ifcfg-eth1
DEVICE=eth1
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none
做成以下启动脚本
#!/bin/sh
/sbin/ifconfig bond0 192.168.10.1 netmask 255.255.255.0 broadcast 192.168.10.255 up
/sbin/ifenslave bond0 eth0
/sbin/ifenslave bond0 eth1
#shutdown -r now
#ifconfig -a
#cat /proc/net/bond0/info
Bonding Mode: active-backup
Currently Active Slave: eth0
