Ubuntu的网络参数保存在文件 /etc/network/interfaces中,默认设置使用dhcp,内容如下:

# The primary network interface

auto eth0

iface eth0 inet dhcp

设置静态ip的方法如下:

  1. 编辑 /etc/network/interfaces

    a. 将dhcp 一行屏蔽

    # The primary network interface

    auto eth0

    #iface eth0 inet dhcp

    b. 添加和静态ip有关的参数

    # The primary network interface

    iface eth0 inet static

    address 192.168.0.10

    netmask 255.255.255.0

    gateway 192.168.0.1

  2. 编辑 /etc/resolv.conf,设置dns

    nameserver 202.96.134.133

    nameserver 202.106.0.20

  3. 执行下面两个命令,启用新设置

    $ sudo ifdown eth0
    $ sudo ifup eth0
