服务器ip配置 & 策略路由配置

添加路由命令：（临时）

ip route add 172.17.0.0/20 via 172.17.0.1 dev em2

ip route add 192.168.13.0/24 via 192.168.1.254 dev eth0

删除路由：

ip route del 192.168.13.0/24

---

#!/system/bin/sh

echo "################ sleep to wait net done! 10 seconds！"

sleep 10

echo "start add route"

busybox route add -net 192.168.12.0/24 gw 192.168.1.254

---

#!/system/bin/sh

sleep 10

busybox route add -net default gw 192.168.1.254

---

永久静态路由需要写到 /etc/sysconfig/network-scripts/route-interface 文件中，比如添加两条静态路由：

[root@centos7 ~]# vi /etc/sysconfig/network-scripts/route-enp0s3

10.15.150.0/24 via 192.168.150.253 dev enp0s3

10.25.250.0/24 via 192.168.150.253 dev enp0s3

添加完毕后重启网络服务生效

service  network restart

centos7配置服务器网络：

/etc/sysconfig/network-scirpts/ifcfg-em1
