问题

如果配置错误或者症状是已知问题，请提出建议。

查看其他文章并将 netcfg/choose_interface=eth0 设置为启动参数。

问题

预计静态网络和主机/域将根据以下预置文件中的设置在 /etc/network/interfaces 中配置。但是，已配置 DHCP。

cat /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp

预置文件中的其他配置（如用户、磁盘分区等）均按预期配置。安装程序日志显示预置。

解决方法

将网络配置放入 kickstart 中。

network --bootproto=static --device=eth0 --hostname=myhost --ip=xxx.96.102.139 --netmask=255.255.255.192 --gateway=xxx.96.102.129 --nameserver=xxx.96.102.141

环境

Static hostname: kickseed
     Icon name: computer-vm
       Chassis: vm
       Boot ID: 2e4cc092b21c429e9e0e0d1a3316cf5d
Operating System: Ubuntu 14.04.3 LTS
        Kernel: Linux 3.19.0-25-generic
  Architecture: x86_64

快速启动

使用kickstart设置安装菜单语言、键盘。

配置

isolinux/isolinux.cfg

# D-I config version 2.0
include menu.cfg
default vesamenu.c32
prompt 0
timeout 1
ui gfxboot bootlogo

isoinux/txt.cfg

default install
label install
  menu label ^Install Ubuntu Server
  kernel /install/vmlinuz
    append  initrd=/install/initrd.gz ks=http://xxx.96.102.150/ks.cfg preseed/url=http://xxx.96.102.150/preseed.txt netcfg/choose_interface=eth0
