1、修改配置檔案/etc/network/interfaces
root@ubuntu:~# sudo gedit /etc/network/interfaces
新增以下內容:
auto eth0 #設定自動啟動eth0介面
iface eth0 inet static #配置靜態IP
address 192.168.11.88 #IP地址
netmask 255.255.255.0 #子網掩碼
gateway 192.168.11.1 #預設閘道器
2、修改DNS
sudo gedit /etc/resolve.conf
nameserver 127.0.0.1 #記得加上
nameserver 8.8.8.8 #當地dns伺服器(用ipconfig /all 檢視本地dns,第一個dns是預設的,共有2個dns)
注:#後面的註釋資訊不要加進去。
3、重啟網路,使配置生效
sudo /etc/init.d/networking restart
4、檢視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

root@ubuntu:~#
注:紅字加粗“192.168.11.88”跟上面配置的ip一樣,表示ip配置成功。
如果網路無法啟動或不穩定,可嘗試如下操作:
gedit /etc/NetworkManager/NetworkManager.conf
managed=false設定成managed=true
