1、安装tftp服务

3、重启并验证服务
[root@cxishs-Nettest~]#/etc/init.d/xinetdrestart Stoppingxinetd:[OK] Startingxinetd:[OK] [root@cxishs-Nettest~]#netstat-au|greptftp udp00*:tftp*:* [root@cxishs-Nettest~]#
使用感想：
在使用过程中，发现tftp服务器有假死现象，从客户端推送文件失败，而服务器上观察服务处于正常状态。
此时重启tftp服务后再次生效。因此，博主在计划任务里周期自动重启tftp服务，以保证tftp服务的可用性。
