6.4. 使​用 PXE 从​网​络​启​动​

To boot with PXE, you need a properly configured server, and a network interface in your computer that supports PXE. For information on how to configure a PXE server, refer to 第 11 章 配​置​一​个​安​装​服​务​器​.
配​置​计​算​机​为​从​网​络​接​口​启​动​。​这​个​选​项​在 BIOS 中​,可​能​被​标​记​为 Network BootBoot Services。​一​旦​您​正​确​地​配​置​了 PXE 启​动​,电​脑​将​不​需​要​其​他​介​质​启​动 Fedora 安​装​系​统​。​
要​通​过 PXE 服​务​器​启​动​计​算​机​:
  1. 确​认​网​络​电​缆​已​插​好​。​网​卡​的​连​接​指​示​灯​会​亮​起​,即​使​计​算​机​没​有​打​开​电​源​。​
  2. 打​开​计​算​机​电​源​。​
  3. 接​下​来​会​出​现​一​个​菜​单​屏​幕​。​按​下​相​应​于​所​需​要​的​选​项​的​数​字​键​。​

PXE 出​错​处​理​

如​果​您​的​计​算​机​没​有​从​网​络​服​务​器​启​动​,检​查 BIOS 是​否​配​置​为​从​正​确​的​网​络​接​口​启​动​。​一​些 BIOS 将​网​络​接​口​标​记​为​可​能​的​启​动​设​备​,但​是​并​不​支​持 PXE 标​准​。​查​看​您​的​硬​件​手​册​来​获​取​更​多​信​息​。​

多​重​NICs和​PXE安​装

Some servers with multiple network interfaces may not assign eth0 to the first network interface as BIOS knows it, which can cause the installer to try using a different network interface than was used by PXE. To change this behavior, use the following in pxelinux.cfg/* config files:
IPAPPEND 2
APPEND ksdevice=bootif
The configuration options above causes the installer to use the same network interface as BIOS and PXE use. You can also use the following option:
ksdevice=link
This option causes the installer to use the first network device it finds that is linked to a network switch.
