Ubuntu配置和修改IP地址

1、修改配置文件/etc/network/interfaces
root@ubuntu:~# sudo gedit /etc/network/interfaces

添加以下内容:
auto eth0                  #设置自动启动eth0接口
iface eth0 inet static     #配置静态IP
address 192.168.11.88      #IP地址
netmask 255.255.255.0      #子网掩码
gateway 192.168.11.1        #默认网关

2、修改DNS
sudo gedit /etc/resolve.conf

nameserver 127.0.0.1 #记得加上
nameserver 8.8.8.8 #当地dns服务器(用ipconfig /all 查看本地dns,第一个dns是默认的,共有2个dns)

注:#后面的注释信息不要加进去。

3、重启网络,使配置生效
sudo /etc/init.d/networking restart

4、查看ip是否配置成功 root@ubuntu:~# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:0c:29:2d:89:40 
          inet addr:192.168.11.88  Bcast:192.168.11.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:fe2d:8940/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:223 errors:0 dropped:0 overruns:0 frame:0
          TX packets:253 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:24219 (24.2 KB)  TX bytes:22960 (22.9 KB)
          Interrupt:19 Base address:0×2024

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:16436  Metric:1
          RX packets:48 errors:0 dropped:0 overruns:0 frame:0
          TX packets:48 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:3964 (3.9 KB)  TX bytes:3964 (3.9 KB)

root@ubuntu:~#

注:红字加粗“192.168.11.88”跟上面配置的ip一样,表示ip配置成功。

如果网络无法启动或不稳定,可尝试如下操作:

gedit /etc/NetworkManager/NetworkManager.conf

managed=false设置成managed=true
