linux运维及配置工作中，常常会用到双网卡绑定，少数几台服务器的配置还好，如果是需要配置几十甚至上百台，难免会枯燥乏味，易于出错，我编写了这个双网卡绑定的辅助脚本，可傻瓜式地完成linux双网卡绑定工作，当然，该脚本主要还是用于小批量的系统配置，如需配置大量的服务器，可提取脚本中的bonding函数，稍作修改即可，你值得一试！

1.适用范围

该shell脚本可在以下linux系统创建多个绑定网卡，用于生产环境没问题的：

Redhat 5.x

CentOS 5.x

Kylin 3.x

KUX 2.x

2.脚本特点

----------------------------------------------

------ Network Configuration Assistant ------

----------------------------------------------

The information you have entered:

First NIC :eth0

Second NIC :eth1

bond name :bond1

IP address :192.168.56.11

netmask :255.255.255.0

bonding_mode :mode=1

primary NIC :none

----------------------------------------------

Pls make sure its OK[y/n]:y

如上，脚本在使用过程中，会依次提示输入需要绑定的子网卡名称、绑定网卡名称、IP地址和子网掩码、绑定模式、是否指定主网卡，并主动对系统中可用网卡进行识别并列出，供用户选择，同时会判断输入的各项信息的正确性，保障双网卡绑定顺利进行。

3.使用说明

首先将脚本上传至linux系统任意目录下，使用root用户执行：

[root@node1 tmp]# sh bonding_v2.0.sh

----------------------------------------------

------ Network Configuration Assistant ------

----------------------------------------------

4 network cards available:

eth0 eth1 eth2 eth3

----------------------------------------------

Please enter the First NIC:_

首先脚本会列出系统中有多少可用网卡，并提示输入需要绑定的第一块子网卡的名称，这里输入eth2。

无需担心输入错误，输入重复等问题，脚本会自动判断你的输入信息是否正确。

----------------------------------------------

------ Network Configuration Assistant ------

----------------------------------------------

4 network cards available:

eth0 eth1 eth2 eth3

The information you have entered:

First NIC : eth2

----------------------------------------------

Please select the second NIC:_

接着输入需要绑定的第二块网卡的名称eth3，如果输入错误会出现相应的提示，比如错输入为eth8，会提示需要重新输入：

----------------------------------------------

------ Network Configuration Assistant ------

----------------------------------------------

4 network cards available:

eth0 eth1 eth2 eth3

The information you have entered:

First NIC : eth2

----------------------------------------------

eth8 is not available,Please enter another one.

Please select the second NIC:_

正确输入需要绑定的第二块网卡eth3后，如果linux系统中之前不存在绑定网卡，则默认第一个绑定网卡的名称为bond0，如果系统中存在绑定网卡，脚本会提示输入bondN(N为数字)：

----------------------------------------------

------ Network Configuration Assistant ------

----------------------------------------------

The information you have entered:

First NIC : eth2

Second NIC : eth3

bond name : bond0

----------------------------------------------

The default first bond name is -- bond0.

Please enter an IP address:_

按照提示输入需要绑定的IP地址，比如10.1.1.1

脚本会自动判断输入的IP地址格式和范围是否正确，无需担心输入错误

----------------------------------------------

------ Network Configuration Assistant ------

----------------------------------------------

The information you have entered:

First NIC : eth2

Second NIC : eth3

bond name : bond0

IP address : 10.1.1.1

----------------------------------------------

Pls enter the NETMASK[255.255.255.0]:_

输入IP地址后，会提示输入子网掩码，默认为255.255.255.0，直接回车即可，也可以输入自定义的子网掩码。

----------------------------------------------

------ Network Configuration Assistant ------

----------------------------------------------

The information you have entered:

First NIC : eth2

Second NIC : eth3

bond name : bond0

IP address : 10.1.1.1

netmask : 255.255.255.0

----------------------------------------------

Pls enter the bonding_mode[default:mode=1,active-backup]:_

这一步是输入网卡绑定级别，默认使用主备模式：mode=1，直接回车即可，也可以输入自定义的绑定级别(如输入 mode=6)，格式为：

mode=｛0,1,2,3,4,5,6｝

----------------------------------------------

------ Network Configuration Assistant ------

----------------------------------------------

The information you have entered:

First NIC :eth2

Second NIC :eth3

bond name :bond0

IP address :10.1.1.1

netmask :255.255.255.0

bonding_mode :mode=1

----------------------------------------------

1-eth2

2-eth3

3-none

choose whether to set up the primary NIC or not[default:3-none]:_

此时脚本提示是否设置primary网卡，primary网卡的作用是在子网卡均正常时，primary网卡优先处于活动状态，这里默认为不设置primary网卡，也可以输入数字1或2选择一个网卡为primary网卡。

----------------------------------------------

------ Network Configuration Assistant ------

----------------------------------------------

The information you have entered:

First NIC :eth2

Second NIC :eth3

bond name :bond0

IP address :10.1.1.1

netmask :255.255.255.0

bonding_mode :mode=1

primary NIC :none

----------------------------------------------

Pls make sure its OK[y/n]:_

至此，所有信息输入完毕，脚本会让您判断输入的所有信息是否正确，正确则输入y，进行下一步操作，否则输入n，重新输入以上信息。

----------------------------------------------

------ Network Configuration Assistant ------

----------------------------------------------

Complete!

File backup directory: /etc/sysconfig/network-scripts/inspur_bak

you can check the file and then restart the network service.

1 ) service network restart

2 ) exit

----------------------------------------------

Please make your choice:_

看到这里时，所有绑定网卡的配置文件已经修改完毕了，输入1重启网络服务；输入2直接退出脚本。

建议选择重启网络服务，如果直接退出脚本而不重启网络服务，修改的配置文件是不会生效的，并且在使用该脚本创建下一个绑定网卡时显示信息会出现异常(因为脚本通过ifconfig命令获取当前网卡信息)。

you can check the file and then restart the network service.

1 ) service network restart

2 ) exit

----------------------------------------------

Please make your choice:1

正在关闭接口 eth0： [确定]

正在关闭接口 eth1： [确定]

正在关闭接口 eth2： [确定]

正在关闭接口 eth3： [确定]

关闭环回接口： [确定]

弹出环回接口： [确定]

弹出界面 bond0： RTNETLINK answers: File exists

在 bond0 添加地址 10.1.1.1 时出错。

[确定]

弹出界面 eth0： [确定]

弹出界面 eth1： [确定]

第一次重启网络服务时可能会出现以上类似报错，无需担心，其实配置已经完成，再次重启网络服务即恢复正常。

在绑定过程中修改的配置文件如下：
