1、修改配置文件/etc/network/interfacesroot@ubuntu:~#sudogedit/etc/network/interfaces添加以下内容：autoeth0#设置自动启动eth0接口ifaceeth0inetstatic#配置静态IPaddress192.168.11.88#IP地址netmask255.255.255.
0#子网掩码gateway192.168.11.
1#默认网关2、修改DNSsudogedit/etc/resolve.confnameserver127.0.0.
1#记得加上nameserver8.8.8.8#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/networkingrestart4、查看ip是否配置成功root@ubuntu:~#ifconfigeth0Linkencap:EthernetHWaddr00:0c:29:2d:89:40inetaddr:192.168.11.88Bcast:192.168.11.255Mask:255.255.255.0inet6addr:fe80::20c:29ff:fe2d:8940/64Scope:LinkUPBROADCASTRUNNINGMULTICASTMTU:1500Metric:1RXpackets:223errors:0dropped:0overruns:0frame:0TXpackets:253errors:0dropped:0overruns:0carrier:0collisions:0txqueuelen:1000RXbytes:24219(24.2KB)TXbytes:22960(22.9KB)Interrupt:19Baseaddress:0×2024loLinkencap:LocalLoopbackinetaddr:127.0.0.1Mask:255.0.0.0inet6addr:::1/128Scope:HostUPLOOPBACKRUNNINGMTU:16436Metric:1RXpackets:48errors:0dropped:0overruns:0frame:0TXpackets:48errors:0dropped:0overruns:0carrier:0collisions:0txqueuelen:0RXbytes:3964(3.9KB)TXbytes:3964(3.9KB)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
