如何移植ftp服務器到arm板子？

很多廠家提供的sdk，一般都不自帶ftp服務器功能，

需要要發人員自己移植ftp服務器程序。

本文手把手教大家如何移植ftp server到arm板子。

環境

sdk：復旦微
Buildroot 2018.02.3

1. 解壓

$ mkdir ~/vsftpd 
$ cp vsftpd-3.0.2.tar.gz ~/vsftpd 
$ cd ~/vsftpd $ tar xzf vsftpd-3.0.2.tar.gz 
$ cd vsftpd-3.0.2/

軟件包獲取方法：件文末。

2. 配置工具鏈

修改Makefile文件：

CC = arm-linux-gnueabihf-gcc

根據自己的平臺的工具鏈

3. 設置交叉編譯環境&編譯

make 后，當前目錄下會生成兩個文件：vsftpd 和 vsftpd.conf，這兩個文件是我們要用的。

4. 復制文件

將生成的 vsftpd 復制到目標板 /usr/sbin 目錄，vsftpd.conf 復制到目標板 /etc 目錄，并添加 vsftpd 為可執行：

復制執行文件到目標板

vsftpd拷貝到板子usr/sbin

添加可執行權限

chmod +x /usr/sbin/vsftpd

復制配置文件到目標板

 vsftpd.conf 拷貝到板子/etc/

5. 配置

在目標板上創建一個本地用戶ftp，并設置密碼123456：

$ adduser ftp 
Changing password for root 
New password:  
Retype password:  
Password for ftpadmin changed by root

使用 vi 打開 vsftpd.conf 文件，并進行配置，如下配置可實現正常上傳下載功能,（這段可以隨便改)

用戶：ftp

# Example config file /etc/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=YES
#
# Uncomment this to allow local users to log in.
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
#
# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
local_umask=022
file_open_mode=0777
#
# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will
# obviously need to create a directory writable by the FTP user.
anon_upload_enable=YES
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
anon_mkdir_write_enable=YES
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES
#
# Activate logging of uploads/downloads.
xferlog_enable=YES
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES
#
# If you want, you can arrange for uploaded anonymous files to be owned by
# a different user. Note! Using "root" for uploaded files is not
# recommended!
#chown_uploads=YES
#chown_username=whoever
#
# You may override where the log file goes if you like. The default is shown
# below.
xferlog_file=/var/log/vsftpd.log
#
# If you want, you can have your log file in standard ftpd xferlog format.
# Note that the default log file location is /var/log/xferlog in this case.
#xferlog_std_format=YES
#
# You may change the default value for timing out an idle session.
#idle_session_timeout=600
#
# You may change the default value for timing out a data connection.
#data_connection_timeout=120
#
# It is recommended that you define on your system a unique user which the
# ftp server can use as a totally isolated and unprivileged user.
#nopriv_user=ftpsecure
#
# Enable this and the server will recognise asynchronous ABOR requests. Not
# recommended for security (the code is non-trivial). Not enabling it,
# however, may confuse older FTP clients.
#async_abor_enable=YES
#
# By default the server will pretend to allow ASCII mode but in fact ignore
# the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode.
# Beware that on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.
#ascii_upload_enable=YES
#ascii_download_enable=YES
#
# You may fully customise the login banner string:
ftpd_banner=Welcome to 6902 FTP service.
#
# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd.banned_emails
#
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
# (Warning! chroot'ing can be very dangerous. If using chroot, make sure that
# the user does not have write access to the top level directory within the
# chroot)
#chroot_local_user=YES
#chroot_list_enable=YES
# (default follows)
#chroot_list_file=/etc/vsftpd.chroot_list
#
# You may activate the "-R" option to the builtin ls. This is disabled by
# default to avoid remote users being able to cause excessive I/O on large
# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
# the presence of the "-R" option, so there is a strong case for enabling it.
#ls_recurse_enable=YES
#
# When "listen" directive is enabled, vsftpd runs in standalone mode and
# listens on IPv4 sockets. This directive cannot be used in conjunction
# with the listen_ipv6 directive.
listen=YES
#
# This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6
# sockets, you must run two copies of vsftpd with two configuration files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=YES

ftp_username=ftp            #登錄用戶
secure_chroot_dir=/mnt/     #

6. 打開vsftp

配置完之后，在目標板上打開vsftp，命令：

# /usr/sbin/vsftpd &

注意，后面還有一個 &，表示該服務放到后臺運行。

7. 設置開機自啟動

如果要讓 vsftpd 開機啟動，可以創建下面文件S70vsftpd，

然后將該文件添加到/etc/init.d/目錄下。

#! /bin/sh

set -e

DESC="vsftpd"
NAME=vsftpd
DAEMON=/usr/sbin/$NAME

case "$1" in
  start)
	printf "Starting $DESC: "
	start-stop-daemon -S -b -x $NAME
	echo "OK"
	;;
  stop)
	printf "Stopping $DESC: "
	start-stop-daemon -K -x $NAME
	echo "OK"
	;;
  restart|force-reload)
	echo "Restarting $DESC: "
	$0 stop
	sleep 1
	$0 start
	echo ""
	;;
  *)
	echo "Usage: $0 {start|stop|restart|force-reload}" >&2
	exit 1
	;;
esac

exit 0

開啟vsftpd：

 /etc/init.d/S70vsftpd restart

重啟vsftpd:

 /etc/init.d/S70vsftpd restart

8. 客戶端測試

下面以pc為例：

C:\Users\ricks>ftp
ftp> open 192.168.31.45
連接到 192.168.31.45。
220 Welcome to EC20 FTP service.
