环境mint17.2

1.安装

dpkg -l|grep ftp

sudo apt-get install vsftpd

2.去根目录创建一个文件上传的文件夹

sudo mkdir /ftpfile

3.创建一个用户，他只对上传文件有权限，对系统登录无权限

sudo useradd ftpuser -d /ftpfile/ -s /bin/bash

4.用chown修改ftpfile的用户和组

sudo chown -R ftpuser.ftpuser /ftpfile/

5.重置用户的密码

sudo passwd ftpuser

6.去ftpfile文件夹中创建一个html文件

sudo gedit /ftpfile/index.html

7.配置ftp服务器

先找到ftp的安装位置： whereis vsftpd

修改配置文件：sudo gedit /etc/vsftpd.conf

ftpd_banner=Welcome to vsftp service.(用户登录ftp服务器时候的欢迎信息)

local_root=/ftpfile(本地目录)

use_localtime=yes

重要的是增加这几句：

userlist_deny=NO

userlist_enable=YES

userlist_file=/etc/allowed_users

write_enable=YES

seccomp_sandbox=NO

在/etc/allowed_users增加ftpuser，这个文件表示可以登录ftp服务器的账户

设置端口范围

pam_service_name=vsftpd(采用被动模式)

pasv_min_port=61001

pasv_max_port=62000

配置防火墙iptables

sudo apt-getinstall iptables-persistent(安装配置iptables的文件)

添加防火墙规则

-A INPUT -p TCP --dport 61001:62000 -j ACCEPT

-A OUTPUT -p TCP --sport 61001:62000 -j ACCEPT

-A INPUT -p TCP --dport 20 -j ACCEPT

-A OUTPUT -p TCP --sport 20 -j ACCEPT

-A INPUT -p TCP --dport 21 -j ACCEPT

-A OUTPUT -p TCP --sport 21 -j ACCEPT

查看修改这个文件/etc/ftpusers，这个文件里面记录的是不能登录ftp服务器的用户

sudo gedit /etc/ftpusers

重新启动防火墙

重启ftp服务器

sudo service vsftpd restart

8.ftp服务器的验证

附上/etc/vsftpd.conf整个配置文件：# 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.

#

#

# Run standalone?  vsftpd can run either from an inetd or as a standalone

# daemon started from an initscript.

listen=YES

#

# Run standalone with IPv6?

# Like the listen parameter, except vsftpd will listen on an IPv6 socket

# instead of an IPv4 one. This parameter and the listen parameter are mutually

# exclusive.

#listen_ipv6=YES

#

# Allow anonymous FTP? (Disabled by default)

anonymous_enable=NO

#

# 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

#

# 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

#

# If enabled, vsftpd will display directory listings with the time

# in  your  local  time  zone.  The default is to display GMT. The

# times returned by the MDTM FTP command are also affected by this

# option.

use_localtime=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 blah FTP service.

local_root=/ftpfile

#

# 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 restrict local users to their home directories.  See the FAQ for

# the possible risks in this before using chroot_local_user or

# chroot_list_enable below.

#chroot_local_user=YES

#

# 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

#

# Customization

#

# Some of vsftpd's settings don't fit the filesystem layout by

# default.

#

# This option should be the name of a directory which is empty.  Also, the

# directory should not be writable by the ftp user. This directory is used

# as a secure chroot() jail at times vsftpd does not require filesystem

# access.

secure_chroot_dir=/var/run/vsftpd/empty

#

# This string is the name of the PAM service vsftpd will use.

pam_service_name=vsftpd

pasv_min_port=61001

pasv_max_port=62000

#

# This option specifies the location of the RSA certificate to use for SSL

# encrypted connections.

rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem

# This option specifies the location of the RSA key to use for SSL

# encrypted connections.

rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key

userlist_deny=NO

userlist_enable=YES

userlist_file=/etc/allowed_users

write_enable=YES

seccomp_sandbox=NO
