安装好一台suse11SP2，将iso，autoinst.xml 和susepxe.sh 上传到/root目录，修改脚本中开头的参数，再sh susepxe.sh 就建立PXE服务器，可以批量安装SUSE

susepxe

#!/bin/bash
# prepare: 
#        a  server installed suse 11 sp2 
#        ISO of suse 
#        autoinst.xml
#        this script
# usage:
#        modify this script's line between 18 ~ 26
#        make this parameter correct
# description:
#        this server is a dhcp(PXE) server and tftp server and vsftp srever
#        dhcp use local_eth as dhcp enthernet interface 
#        other machines in the broadcast  using pxe boot  will use the autoinstfile and install suse paralel
#        if you want paralel and automation ,you can modify the xml .
#        
#
