2.install && configuration dhcpserver
[root@PXES CentOS]# cd /tmp/cdrom/CentOS/
[root@PXES CentOS]# rpm -ivh dhcp-3.0.5-18.el5.i386.rpm
[root@PXES CentOS]# vi /etc/dhcpd.conf  ##add content   dhcpd.conf bk
ddns-update-style interim;
ignore client-updates;
allow booting;
allow bootp;
subnet 192.168.195.0 netmask 255.255.255.0 {
        range  192.168.195.100 192.168.195.200;
        option routers                  192.168.195.254;

[root@PXES CentOS]# cd /usr/lib/syslinux/
[root@PXES syslinux]# cp pxelinux.0 /tftpboot/

5.copy boot kerneal file
[root@PXES syslinux]# cd /tmp/cdrom/isolinux/
[root@PXES isolinux]# cp vmlinuz initrd.img /tftpboot/
[root@PXES isolinux]# mkdir /tftpboot/pxelinux.cfg
[root@PXES isolinux]# cp /tmp/cdrom/isolinux/isolinux.cfg /tftpboot/pxelinux.cfg/default

 

6.modify boot file
[root@PXES isolinux]# chmod 755 /tftpboot/pxelinux.cfg/default
[root@PXES isolinux]# vi /tftpboot/pxelinux.cfg/default   ##并修改如下
default linux
prompt 0
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 ks=nfs:192.168.195.1:/mnt/install/ks.cfg initrd=initrd.img
label text
  kernel vmlinuz
  append initrd=initrd.img text
label ks
  kernel vmlinuz
  append ks initrd=initrd.img
label local
  localboot 1
label memtest86
  kernel memtest
  append -

6.install nfs
[root@PXES isolinux]# mkdir /mnt/install
[root@PXES isolinux]# cd /tmp/cdrom/
[root@PXES CentOS]# cp -Rf * /mnt/install/

7.send nfs share dir
[root@PXES CentOS]# vi /etc/exports
/mnt/install/ *(ro,sync)
[root@PXES CentOS]# rpm -ivh portmap-4.0-65.2.2.1.i386.rpm
[root@PXES CentOS]# rpm -ivh libgssapi-0.10-2.i386.rpm libevent-1.1a-3.2.1.i386.rpm nfs-utils-lib-1.0.8-7.2.z2.i386.rpm nfs-utils-1.0.9-40.el5.i386.rpm

[root@PXES CentOS]# service portmap start
Starting portmap:                                          [  OK  ]
[root@PXES CentOS]# service nfs start
Starting NFS services:                                     [  OK  ]
Starting NFS daemon:                                       [  OK  ]

[root@PXES CentOS]# showmount -e localhost
Export list for localhost:
/mnt/install *

 

8.configure kickstart
[root@PXES install]# cp /root/anaconda-ks.cfg /mnt/install/ks.cfg   ##如果没有KS范本，可以从本地COPY
[root@PXES install]# chmod a+r /mnt/install/ks.cfg   ##如果从光盘COPY的记得加权限
[root@PXES install]# vi /mnt/install/ks.cfg  ##本例是直接创建KS.cfg内容如下

9.close iptables and start dhcpd
[root@PXES install]# service iptables stop
Flushing firewall rules:                                   [  OK  ]
Setting chains to policy ACCEPT: filter                    [  OK  ]
Unloading iptables modules:                                [  OK  ]
[root@PXES install]# service dhcpd start
Starting dhcpd:                                            [  OK  ]

10.other config
[root@PXES install]# chkconfig nfs on
[root@PXES install]# chkconfig portmap on
[root@PXES install]# chkconfig dhcpd on
[root@PXES install]# chkconfig xinetd on
[root@PXES install]# chkconfig iptables off

11.troubleshooting
Q:引导到boot位置时，停止，不会自动往下执行。
A：请确保default文件prompt 有设为0

Q:发现没法mount ks.cfg文件？
A：确保是手工执建一个ks.cfg文件，并非直接COPY过来的。
