首先关闭网络图形界面

sudo service network-manager stop

然后

sudo vim /etc/network/interfaces

修改里面的内容

# interfaces(5) file used by ifup(8) and ifdown(8)
#auto lo
#iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.119.142
netmask 255.255.255.0
gateway 192.168.119.254


auto eth1
iface eth1 inet static
address 192.168.119.145
netmask 255.255.255.0
gateway 192.168.119.254

然后重启网络

sudo /etc/init.d/networking restart
