1. dmesg | grep eth查看網(wǎng)卡信息，有時eth0會被改成eth1，如果改成eth1，則下面的配置中有eth0的地方要做相應(yīng)調(diào)整

2. sudo vim /etc/network/interfaces

auto eth0
iface eth0 inet static #dhcp或static
address 192.168.7.2 #IP
netmask 255.255.255.0 #子網(wǎng)掩碼
gateway 192.168.7.1#網(wǎng)關(guān)

3. sudo vim /etc/resolvconf/resolv.conf.d/base

nameserver 192.168.7.1 #網(wǎng)關(guān)

nameserver 114.114.114.114 #DNS

然后重啟服務(wù)器即可。
