ubuntu设置IP地址、网关的方法

打开terminal（用Ctrl+Alt+T打开）

1. 输入ifconfig 

打印如下：

enp1s0    Link encap:Ethernet  HWaddr 6c:4b:90:0b:53:be  
          inet addr:192.168.1.101  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::1fbf:55e3:1c4c:c79d/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:144897 errors:0 dropped:630 overruns:0 frame:0
          TX packets:13548 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:13441598 (13.4 MB)  TX bytes:1943215 (1.9 MB)
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:7441 errors:0 dropped:0 overruns:0 frame:0
          TX packets:7441 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1
          RX bytes:727906 (727.9 KB)  TX bytes:727906 (727.9 KB)

wlp2s0    Link encap:Ethernet  HWaddr 34:f6:4b:8e:8e:83  
          inet addr:192.168.17.208  Bcast:192.168.17.255  Mask:255.255.255.0
          inet6 addr: fe80::7b1:7fd6:cdbc:29a0/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:39311 errors:0 dropped:0 overruns:0 frame:0
          TX packets:34360 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:19874047 (19.8 MB)  TX bytes:6833538 (6.8 MB)

2.开始设置IP，网关等

sudo vi /etc/network/interfaces

#静态设置IP地址

auto lo 

iface lo inet loopback 

 

auto enp1s0


iface enp1s0 inet static

        address 192.168.12.89（换成你的IP地址）

        netmask 255.255.255.0

        gateway 192.168.12.1（换成你的网关）

#自动获得IP地址

auto lo

iface lo inet loopback

auto eth0

iface eth0 inet dhcp

 

3.重新启动网卡

sudo /etc/init.d/networking restart

 

完成
