1、route 的常用的命令
- route -n
参考:Linux中的路由 route和traceroute - route add
route add -net 192.168.80.0 netmask 255.255.255.0 gw 192.168.80.254
route add -net 192.168.80.0 netmask 255.255.255.0 dev enp0s8 - route del
route del -net 192.168.80.0 netmask 255.255.255.0 gw 192.168.80.254
route del -net 192.168.80.0 netmask 255.255.255.0 dev enp0s8
2、创建虚拟网卡
方法一:临时生效 [root@www ~]# ifconfig [device] [ IP ] netmask [netmask ip] [up|down] [root@www ~]# ifconfig eth0:0 192.168.0.100 netmask 255.255.255.0 up 方法二:永久生效(推荐) [root@www ~]# cd /etc/sysconfig/network-scripts [root@www network-scripts]# vim ifcfg-eth0:0 DEVICE=eth0:0 <==相當重要!一定要與檔名相同的裝置代號! ONBOOT=yes BOOTPROTO=static IPADDR=192.168.0.100 NETMASK=255.255.255.
