redhat 5.9做RAC前的双网卡绑定

      最近这几天忙着装上了服务器，redhat 5.9，华为的存储，并装上多路径软件。在施工的过程中自己配置的双网卡bonding .完后自己整理以便于日后有所忘记。

      环境介绍：

 root@wtrac1[/root]#uname -aLinux wtrac1 2.6.18-348.el5 #1 SMP Wed Nov 28 21:22:00 EST 2012 x86_64 x86_64 x86_64 GNU/Linuxroot@wtrac2[/root]#uname -aLinux wtrac2 2.6.18-348.el5 #1 SMP Wed Nov 28 21:22:00 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

          步骤：
