linux - CentOS 7.2服务器上/etc/sysconfig/network中设置的默认网关是 "ignored"

Question

我有一台带有两个网卡的 CentOS 7.2 服务器。我在/etc/sysconfig/network 中将默认网关设置为 192.168.0.1。但是，重新启动服务器后，该设置不会生效，我猜测是 eth1 使用的 DHCP 覆盖了它。

有办法解决这个问题吗？我尝试将“DEFROUTE=yes”添加到/etc/sysconfig/network-scripts/ifcfg-eth0 但没有成功。

我也愿意运行“sudo ip route replacement default via 192.168.0.1 dev eth0”，但是最好把它放在哪里？

下面提供了服务器的基本信息。如果您需要更多信息，请告诉我。

非常感谢!

在当前的 Red Hat 实现中，/etc/sysconfig/network 文件已被弃用。您可以使用特定于接口(interface)的配置文件中的 DEFROUTE 变量指定用户的默认连接。在 ifcfg-eth0 中设置 DEFROUTE=yes。
