Ubuntu更改國內源，設置固定IP和DNS

一 更改國內源

 

1 首先備份官方源，以避免設置錯誤可恢復。

$ sudo cp /etc/apt/sources.list /etc/apt/sources.list.back

 

2 用編輯器打開 /etc/apt/sources.list文件。

$ sudo nano /etc/apt/sources.list

 

3 刪除原有的源，在編輯器中添加新源（阿里源,14.04）。如圖所示：

deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

 

二 設置固定IP

 1 編輯 /etc/network/interfaces

$ sudo nano /etc/network/interfaces

 

2 註釋掉 iface eth0 inet dhcp這一行並添加以下內容，以設置爲固定IP 192.168.1.85爲例

iface eth0 inet static
address 192.168.1.85
netmask 255.255.255.0
gateway 192.168.1.1

 

3 重啓eth0，不是root的加sudo

$ ifconfig eth0 down
$ ifconfig eth0 up

 

4 重啓網卡

$ /etc/init.d/networking restart

 

三 設置靜態dns服務器

 

1 增長文件

$ sudo nano /etc/resolvconf/resolv.conf.d/tail

 

2 增長nameserver，以下：

nameserver 202.102.134.68
nameserver 8.8.8.8

 

3 重啓dns解析

$ sudo /etc/init.d/resolvconf restart
