急问：关于网络安装linux

小谦

整了2天都没弄出来……晕死了……

用pxe + dhcp + tftp + nfs安装。

nfs弄好了，把安装光盘里的文件放进nfs里面；客户端用光盘启动，然后选择nfs安装能装上。
但选网络启动的时候，总是装不上。估计是tftp文件夹下少了什么东西，或这pxelinux.cfg里面的文件设置错了。

服务器端ip是192.168.133.130，客户端ip是192.168.133.120。

服务器端tftp文件夹下目录：
[root@localhost linux-install]# dir
boot.msg     initrd.img   param.msg   pxelinux.cfg  vmlinuz
general.msg  options.msg  pxelinux.0  rescue.msg

服务器端tftp目录下/tftpboot/linux-install/pxelinux.cfg/default
default linux
prompt 1
timeout 600
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg
F4 param.msg
F5 rescue.msg
label linux
  kernel vmlinuz
  append initrd=initrd.img

  kernel vmlinuz
  append initrd=initrd.img text

  append ks initrd=initrd.img

选的资料不对啊~555
/etc/dhcp.conf中next-server没填……
似乎有些linux中dhcp和tftp同一个服务器的话这项不用填，而有些版本是一律要填……
