概述

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！

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.xCentOS 5.xKylin 3.xKUX 2.x脚本特点

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。

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：

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。

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：

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)：

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

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。

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：

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。

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。

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)。

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：
