本文详细介绍了在Linux环境下安装并配置TFTP服务的过程，包括安装TFTPD-HPA服务程序与客户端，修改配置文件以实现安全高效的数据传输，并提供了手动启动、停止、重启TFTP服务的方法。

1、安装软件包

sudo apt-get install tftpd-hpa tftp-hpa

其中tftpd-hpa是服务程序，tftp-hpa是客户端。

2、修改配置文件

vim /etc/default/tftpd-hpa

# /etc/default/tftpd-hpa

TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/home/xxx/tftpboot"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="-l -c -s"

前三条不解释，一看就明白，TFTP_OPTIONS的三个选项的解释如下：

-l, --listen
Run the server in standalone (listen) mode, rather than run from inetd. In listen mode, the --timeout option is ignored, and the --address option can be used to specify a specific local address or port to listen to.

--create, -c
Allow new files to be created. By default, tftpd will only allow upload of files that already exist. Files are created with default permissions allowing anyone to read or write them, unless the --permissive or --umask options are specified.

--secure, -s
Change root directory on startup. This means the remote host does not need to pass along the directory as part of the transfer, and may add security. When --secure is specified, exactly one directory should be specified on the command line. The use of this option is recommended for security as well as compatibility with some boot ROMs which cannot be easily made to include a directory name in its request.

3.系统默认tftp的服务是随机启动的，如需手动开启、关闭、重启tftp服务，分别执行以下命令即可：

sudo service tftpd-hpa start

sudo service tftpd-hpa stop

sudo service tftpd-hpa restart
