【Linux开发环境搭建】TFTP服务开启与使用
一、Ubuntu端TFTP服务器配置：
-
Ubuntu下使用以下命令安装TFTP服务：（安装 tftp-hpa 和 tftpd-hpa）
sudo apt-get install tftp-hpa tftpd-hpa- 创建一个TFTP文件夹
mkdir /home/pjw/linux/tftpboot- 给予TFTP目录可读可写可执行权限（文件或文件夹给权限后变为绿色）
chmod 777 /home/pjw/linux/tftpboot
- 安装xinetd
sudo apt-get install xinetd- 配置xinetd
新建并编辑文件/etc/xinetd.d/tftp
sudo vi /etc/xinetd.d/tftp输入如下内容：
server tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /home/pjw/linux/tftpboot/
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}-
启动 tftp 服务
sudo service tftpd-hpa start- 编辑/etc/default/tftpd-hpa 文件
sudo vi /etc/default/tftpd-hpa修改为以下内容：
# /etc/default/tftpd-hpa
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/home/pjw/linux/tftpboot"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="-l -c -s"- 重启TFTP服务器
sudo service tftpd-hpa restart
二、TFTP服务使用：
- 将 zImage 镜像文件拷贝到 tftpboot 文件夹 中，并且给予 zImage 相应的权限
cp zImage /home/pjw/linux/tftpboot/
cd /home/pjw/linux/tftpboot/
chmod 777 zImageuboot 中的 tftp 命令格式如下：
#tftpboot DRAM中的存放地址 要从Ubuntu中下载的文件
