要搭建一个tftp server只需要简单的三步：
1.将以下内容放到/etc/xinetd.d/tftp
2.创建/tftpboot目录，并修改权限：chmod 777 /tftpboot
3.启动tftp server：xinetd -f /etc/xinetd.d/tftp

# protocol. The tftp protocol is often used to boot diskless \
# workstations, download configuration files to network-aware printers, \
# and to start the installation process for some operating systems.
#file exist :
# this file conten must include by /etc/xinetd.d/tftp
#how to start tftp server:
# xinetd -f /etc/xinetd.d/tftp
service tftp
