centos pxe tftp kickstart httpd

首先安装httpd dhcp tftp
ddns-update-style interim;
ignore client-updates;

subnet 10.10.10.0 netmask 255.255.255.0 {

# --- default gateway
        option routers                  10.10.10.1;
        option subnet-mask              255.255.255.0;

        option nis-domain               "domain.org";
        option domain-name              "domain.org";
        option domain-name-servers      10.10.10.1;
        filename "pxelinux.0";
        next-server 10.10.10.200;
        option time-offset              -18000; # Eastern Standard Time

#       option netbios-name-servers     192.168.1.1;

#       option netbios-node-type 2;

        range dynamic-bootp 10.10.10.50 10.10.10.60;
        default-lease-time 21600;
        default-lease-time 21600;
        max-lease-time 43200;
        # we want the nameserver to appear at a fixed address
#       host ns {
#               next-server marvin.redhat.com;
#               hardware ethernet 12:34:56:78:AB:CD;
#               fixed-address 207.175.42.254;
#       }
}

vi /etc/xinetd.d/tftp

disable = no 将disable项改为NO。

复制内核启动文件到tftp目录：

cp /usr/lib/syslinux/pxelinux.0   /tftpboot/

将centos5.4光盘拷贝进入httpd目录

#cp /var/www/html/image/pxeboot/initr.img  /tftpboot/

#cp /var/www/html/image/pxeboot/vmlinuz    /tftpboot/

#cp /mvar/www/html/isolinux/*.msg       /tftpboot/

#mkdir /tftpboot/pxelinux.cfg

#cp /var/www/html/isolinux/isolinux.cfg /tftpboot/pxelinux.cfg/default
修改default
在最后添加

label autoinstall

kernel vmlinuz

append ks= initrd=initrd.img devfs=nomount ramdisk_size=9216 nofb

vi /tftpboot/boot.msg
- To Auto Install ^O0bCentOS5.2 Linux^O07, type:^O0blinux autoinstall ^O07.

复制一份anaconda-install.cfg 为auto.cfg放在httpd目录下。加入权限，chmod 755


设置系统从pxe启动
