service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable = no #"yes"改为"no"
per_source = 11
cps = 100 2
flags = IPv4
}
# cp -rf /var/www/html/ubuntu1204/install/netboot/*/var/lib/tftpboot/
# service xinetd restart
4.修改配置
