SciLinux6（RHEL6）如何指定networking设置和路由的redhat方式？

我有一个SciLinux 6盒子，里面有5个nic。我没有得到我想要的networkingconfiguration（特别是路由）。虽然我可以肯定的是在rc.local的末尾添加了一些路由语句，但我宁愿使用“redhat”的方式。

我想要的是一些指导如何：

如下所示更正路由。
如下所示更正默认路线。
我很乐意让169.254的愚蠢消失，所以如何做到这一点的方向是值得赞赏的。

所以有5个nics，eth0-eth4。请注意，eth4插入思科交换机上的RSPAN端口，仅作为完整内容包含在内。

这是当前路由：

您需要在/etc/sysconfig/network-scripts目录中创build一个名为route-ethX的文件（其中X是要连接路由的接口）。

例如，我需要将我们的公共办公室路由到互联网上，而不是由于聊天方式检查您是谁的vpn。所以我在我们的办公室路由器中有一个名为route-eth0的文件，如下所示：

 64.34.119.10 via 74.101.14.1 dev eth0

您可以在这里阅读RHELnetworkingconfiguration

169.254 / 16个地址来自零configuration。您应该能够通过以下方式禁用它们：

去169.254.0.0的路线从哪里来？

基本上，将NOZEROCONF = yes添加到/ etc / sysconfig / network文件。
