嵌入式开发环境搭建linux TFTP服务器

1.安装tftp服务器
   [root@vibexie vibe]# yum install tftp tftp-server
2.配置tftp服务器
    编辑/etc/xinetd.d/tftp文件
    [root@vibexie xinetd.d]# vi tftp
 

 # default: off
 # description: The tftp server serves files using the trivial file transfer \
 #       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.
 service tftp
 {
 socket_type = dgram
 protocol = udp
 wait = yes
 user = root
 server = /usr/sbin/in.tftpd
 server_args = -s /home/vibe/tftp -c  /*修改项server_args= -s         -c，其中处可以改为你的tftp-server的根目录，参数-s指定chroot，-c指定了可以创建文                                        件。*/
 disable = no   /*默认为yes,表示关闭tftp服务器,我们修改为no,表示开启*/
 per_source = 11
 cps = 100 2
 flags = IPv4
 }

修改上述注释的两项即可，其他想了解的话可以百度下。

3.创建tftp服务器的根目录，并且其他组增加w权限
    [root@vibexie ~]$ mkdir tftp
    [root@vibexie ~]$ chmod o+w tftp

4.启动tftp服务器
    [root@vibexie vibe]# systemctl start xinetd.service

5.测试
   将一个文件放入tftp根目录中，如我放入lcd.bin
    在目标板上下载linux tftp服务器中的lcd.bin

OK！
