pxe-e32:tftp open timeout

linuxcai

pxe server为rhel
其中dhcp以及tftp服务都已开启，disable设置成no，防火墙也已关闭
为什么客户端报拿到ip后，报这个错误呢？

检查下tftp的目录下pxe启动所需要的文件是否都齐全了

检查下dhcpd.conf里面allow booting;
allow bootp;
next-server 1.2.3.4;(用你的ip替换1.2.3.4)
是否配置了?

楼主在服务器上执行setenforce 0,暂时关闭下selinux,看看客户机是否能够正常pxe启动

    确实是用nfs，不过我的nfs服务已经开启了啊

楼主检查下nfs共享正常不?
