Pxe自动安装脚本配置方法：
yum安装system-config-kickstart
[root@localhost ~]# yum -y install system-config-kickstart
修改/var/lib/tftpboot/pxelinux.cfg/default文件：
在append initrd 的最后添加ks路径，用空格隔开： ks=ftp://192.168.140/ks.cfg
[root@localhost ~]# system-config-kickstart
出现图形化界面，进行配置：
保存后的脚本内容如下:
[root@localhost ~]# more ks.cfg
#platform=x86, AMD64, 或 Intel EM64T
#version=DEVEL
# Install OS instead of upgrade
