本次实验环境：

RedHat Linux 9.0
Kernel: 2.4.20-8
eth0/eth1

        我的Linux上两块网卡分别配了公有地址：eth0-xxx.xxx.180.59和eth1-10.4.2.3，这台机器是一台没有显示器和键盘鼠标的主机，所以我首先选择远程登录的那个接口为主（就是说即使绑定不成功我也希望还能远程登录成功）。整个操作如下：

1. 编写bond0接口配置文件：
   #cd /etc/sysconfig/network-scripts/
   #ls ifcfg-*
   ifcfg-eth0  ifcfg-eth1  ifcfg-lo
   #cp ifcfg-eth0 ifcfg-bond0
   #
2. 编辑/etc/sysconfig/network-scripts/ifcfg-bond0，其DEVICE=eth0改为DEVICE=bond0。
3. 编辑/etc/modules.conf，在文件末尾加入以下内容：
   alias  bond0 bonding
   options bond0  miimon=100  mode=1
4. 编辑/etc/rc.d/rc.local，在文件末尾加上以下内容：（需要注意的是xxx为你实际地址的部分）
   ifenslave bond0 eth0 eth1
   route add -net xxx.xxx.180.0 netmask 255.255.255.0 bond0
5. 重新启动网卡：
   #/etc/rc.d/init.d/network restart
   Shutting down interface eth0:  [  OK  ]
   Shutting down interface eth1:  [  OK ]
   Shutting down loopback interface:  [ OK ]
   Setting network parameters:  [ OK ]
   Bringing up loopback interface:  [  OK  ]
   Bringing up interface bond0:  [  OK  ]
   Bringing up interface eth0:  [  OK  ]
   Bringing up interface eth1:  [  OK  ]
   #
6. 检查是否成功：
   #netstat -r
   Kernel IP routing table
   Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
   xxx.xxx.180.0     *               255.255.255.0   U         0 0          0 bond0
   xxx.xxx.180.0     *               255.255.255.0   U         0 0          0 eth0
   xxx.xxx.180.0     *               255.255.255.0   U         0 0          0 eth1
   127.0.0.0       *               255.0.0.0       U         0 0          0 lo
   #

绑定成功后用ifconfig查看接口信息，显示如下：（其中inet6的项是IPv6的信息，这台机器支持IPv6）

使用cat命令查看/etc/sysconfig/network-scripts/ifcfg-eth1文件，结果如下：
# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
BOOTPROTO=static
ONBOOT=yes
IPADDR=10.4.2.3
NETMASK=255.255.255.192
GATEWAY=10.4.2.1
NETWORK=10.4.2.0
BROADCAST=10.4.2.255
#

可以看出eth1接口的配置信息并没有改变，但是已经无效。
