/etc/sysconfig/network 在 CENTOS7 上被忽略

我有一台有两个网卡的服务器。默认网关必须位于特定网关上，因此我通过 /etc/sysconfig/network 配置了网关。但显然，NetworkManager 完全忽略了这一点

[root@node1 ~]# cat /etc/sysconfig/network
GATEWAY="10.100.20.1"
[root@node1 ~]# systemctl restart network
[root@node1 ~]# ip r s
default via 10.100.7.1 dev ens160  proto static  metric 1024
10.100.7.0/24 dev ens160  proto kernel  scope link  src 10.100.7.31
10.100.20.0/22 dev ens192  proto kernel  scope link  src 10.100.20.204

有什么提示吗？

编辑：以下是接口配置：

[root@node1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens192
DEVICE="ens192"
ONBOOT=yes
NETBOOT=yes
UUID="e634ce78-f5ea-4b3c-b3ea-1e40ef0b11ac"
BOOTPROTO=none
IPADDR="10.100.20.204"
NETMASK="255.255.252.0"
GATEWAY="10.100.20.1"
HWADDR="XXX"
TYPE=Ethernet
NAME="ens192"
DNS1="193.12.103.2"

[root@node1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens160
DEVICE="ens160"
ONBOOT=yes
NETBOOT=yes
UUID="bee8e636-80b4-45f3-9b74-eb9eb0fed38d"
BOOTPROTO=none
IPADDR="10.100.7.31"
NETMASK="255.255.255.0"
GATEWAY="10.100.7.1"
HWADDR="XXX"
TYPE=Ethernet
NAME="ens160"
DNS1="193.12.103.2"

以下是可能导致该问题的部分消息：

[root@node1 ~]# cat /var/log/messages | grep NetworkManager | grep "Nov  9" | grep "as default for IPv4" -A5 -B5

知道那里提到的是什么样的“政策”吗？

答案1

这有效：

[root@node1 ~]# cat /usr/share/doc/initscripts-9.49.17/sysconfig.txt | grep DEFROUTE
DEFROUTE=yes|no (set this interface as default route? yes is default)

我仍然相信忽略/etc/sysconfig/network是一个错误CentOS Linux release 7.0.1406 (Core)

答案2

我做过的最好方法是添加一个静态路由文件，就像我有两个接口一样

eth0 = private on 10.10.11.10
eth1 = public on 1.2.3.4 (also the default route)

因此，如果我希望 10.0.0.0/8 子网上的所有内部流量都流出 eth0，我只需添加以下文件

/etc/sysconfig/network-scripts/route-eth0

内容如下

default 10.102.51.129 dev eth0
10.0.0.0/8 via 10.102.51.129 dev eth0

10.102.51.129 是我的 eth0 网关
