SciLinux6(RHEL6)如何以 redhat 方式指定网络设置和路由?

SciLinux6(RHEL6)如何以 redhat 方式指定网络设置和路由?

我有一个装有 5 个网卡的 SciLinux 6 盒子。我没有得到我想要的网络配置(特别是路由)。虽然我可以在 rc.local 的末尾放置一堆路由语句,但我宁愿采用“redhat”方式。

我想要的是一些关于如何做的指导:

  1. 按照如下所示更正路由。
  2. 按照如下所示更正默认路由。
  3. 我很想让 169.254 这个愚蠢的事情消失,因此,如果能得到一些关于如何做到这一点的指导,我将非常感激。

因此有 5 个网卡,eth0-eth4。请注意,eth4 插入思科交换机上的 RSPAN 端口,仅出于完整性考虑才包含。

答案1

您需要route-ethX在目录中创建一个名为(其中 X 是您想要附加路由的接口)的文件/etc/sysconfig/network-scripts

例如,我需要将我们的公共办公室路由到互联网而不是 VPN,因为聊天会检查您的身份。所以我有一个名为“route-eth0办公室路由器”的文件,如下所示:

64.34.119.10 via 74.101.14.1 dev eth0

您可以阅读 RHEL 网络配置这里

答案2

169.254/16 地址来自 zeroconf。您应该能够通过以下步骤禁用它们:

到 169.254.0.0 的路由来自哪里?

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