用pxe安装linnux！！

lydongkill

我做了一个pxe服务器，安装linux系统，我走的是http方式，客户端在安装的时候，进入到安装界面后，到获取IP地址了时候，系统就获取不到，手工设置也连接不上http服务器，请问哪位遇到过这样的事情。

注意你的你的dhcp，http服务的搭建

我记得图形化安装，只支持nfs（没有确定，也没验证，我只是用ftp和nfs的方式来网络安装）

具体的配置文件？

dhcpd  tftpd ks文件 httpd

没有人帮忙分析一下，什么原因

我用笔记到哪个网络中，能DHCP获取到IP地址，就是不明白到了安装界面的时候怎么就获取不到IP地址

jerryjzm

给你一个法子来验证，
我可以让笔记本和服务器直连来安装试试（我一般这样做），碰到过使用交换机无法安装的情况
