ubuntu 16.04 pxe install system
https://www.aliyun.com/jiaocheng/122583.html根据上面的内容搭建，
遇到个问题
pxe安装的时候报错，network autoconfiguration failed
your network is probably not using the DHCP protocol.Alternatively,the DHCPserver may be slow or some network hardware is not working properly
网上找了一大圈没看到具体的解决办法！
后来发现是dhcpd.conf文件中的问题。

下面为正确的dhcpd.conf文件配置
root@ubuntu:~# vi /root/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
option domain-name "example.org";
option domain-name-servers 127.0.0.1;
default-lease-time 600;
max-lease-time 7200;
log-facility local7;
subnet 192.168.2.0 netmask 255.255.255.0 { #地址根据实际环境来
range 192.168.2.100 192.168.2.200;
option routers 192.168.2.1; #网关地址不可少
filename "pxelinux.0";
next-server 192.168.2.10; #服务器地址
allow booting;
allow bootp;
}
将dhcpd.conf配置文件改为上面的内容，问题就解决了，不是像网上其他帖子写的报了上图错误就手动输入ip地址，这个是全自动安装的
感谢楼主分享！
