CentOS部署TFTP服务

前端之家收集整理的这篇文章主要介绍了CentOS部署TFTP服务前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

1、安装tftp服务

[root@cxishs-Nettest~]#


2、修改TFTP配置文件

[root@cxishs-Nettest~]#vi/etc/xinetd.d/tftp

#default:off
#description:Thetftpserverservesfilesusingthetrivialfiletransfer\
#protocol.Thetftpprotocolisoftenusedtobootdiskless\
#workstations,downloadconfigurationfilestonetwork-awareprinters,\
#andtostarttheinstallationprocessforsomeoperatingsystems.
servicetftp
{
socket_type=dgram
protocol=udp
wait=yes
user=root
server=/usr/sbin/in.tftpd
server_args=-s/tmp/tftp/data-c##TFTP文件目录,-c表示支持上传
disable=no##开启服务,默认TFTP服务关闭
per_source=11
cps=1002
flags=IPv4
}

"/etc/xinetd.d/tftp"18L,514Cwritten
[root@cxishs-Nettest~]#
[root@cxishs-Nettest~]#mkdir/tmp/tftp
[root@cxishs-Nettest~]#mkdir/tmp/tftp/data
[root@cxishs-Nettest~]#chmod777/tmp/tftp
[root@cxishs-Nettest~]#chmod777/tmp/tftp/data


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。
