简单文件传输TFTP服务器搭建 Linux RHEL6

Tftp 的应用场合

1、交换机或路由器升级或备份

2、无盘工作站 存放boot loader

3、嵌入式开发时装载系统

4、大规模的服务安装布署

 

安装

1、# yum install xinetd

      # yum install -y tftp-server

2、检查是否开机启动

# chkconfig --list | grep xinet

xinetd          0:off   1:off   2:off   3:on    4:on    5:on    6:off

xinetd based services:

        chargen-dgram:  off

        chargen-stream: off

        cvs:            off

        daytime-dgram:  off

        daytime-stream: off

        discard-dgram:  off

        discard-stream: off

        echo-dgram:     off

        echo-stream:    off

        rsync:          off

        tcpmux-server:  off

        time-dgram:     off

        time-stream:    off

3、配置

   # vim /etc/xinetd.d/tftp

service tftp

{

        socket_type             = dgram

        protocol                = udp

        wait                    = yes

        user                    = root

        server                  = /usr/sbin/in.tftpd

        server_args             = -s /var/lib/tftpboot    -c 

      文件存放目录 RHEL5的目录为 /tftp/boot  可自定义 -c 允许上传

        disable                 = no

        per_source              = 11

        cps                     = 100 2

        flags                   = IPv4

}

# chkconfig tftp on   

  也可已直接通过命令将服务改为开机启动

 

[root@rhel1 ~]# chkconfig --list | grep tftp

        tftp:           on

 

 

4、启动服务Xinetd

# /etc/init.d/xinetd start

 

5、验证tftp是否启动成功并监听本地69端口

[root@rhel1 ~]# netstat -anup | grep 69

udp        0      0 0.0.0.0:69                  0.0.0.0:*                               15763/xinetd       

 

6、测试上传和下载

tftp -i 192.168.1.201 put TFTPServ.CNT

tftp -i 192.168.1.201 get vm-tool.tar.gz
