1、修改配置文件/etc/network/interfacesroot@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IPaddress 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DNSsudo gedit /etc/resolve.confnameserver 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 restart4、查看ip是否配置成功 root@ubuntu:~# ifconfigeth0 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:0×2024lo 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.confmanaged=false设置成managed=true
