1、apt-get install vsftpd
；安装后会在/home/下产生名为ftp的文件夹，似乎vsftpd默认目录就是这个
2、/etc/vsftpd.conf
# 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? (Beware - allowed by default if you comment
this out).
anonymous_enable=NO
#这项要设置为NO，否则（本地）无法登录ftp#不知是否是文件夹权限问题！！！
anonymous_enable=YES(后来发现，直接安装完vsftpd后，不删除默认ftp用户，建立/home/ftp可以默认登录）
#
# 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
#
# 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
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 DDLCN 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 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().
chroot_list_enable=YES
# (default follows)
chroot_list_file=/etc/vsftpd.chroot_list
#文件名可能不同或没有此文件，要新建一个再向其中添加用户,如果不在这里添加用户，可能不能把用户目录锁定在特定位置#（又发现，建立新/bin
/false用户、新目录后，不一定需要在此题添加用户，也可访问，前提是要修改目录所属的用户、组，修改，即修改目录的chown和chmod，就可上
传下载）
#
# 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
#
#
# Debian customization
#
# Some of vsftpd's settings don't fit the Debian filesystem layout
by
# default. These settings are
more Debian-friendly.
#
# 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
#
# This string is the name of the PAM service vsftpd will
use.
pam_service_name=vsftpd
#
# This option specifies the location of the RSA certificate to use
for SSL
# encrypted connections.
rsa_cert_file=/etc/ssl/certs/vsftpd.pem
3、将/etc/pam.d/vsftpd 中的
#auth
required
pam_shells.so
注释掉
4、修改完配置重启vsftpd服务即可
/etc/init.d/vsftpd stop
/etc/init.d/vsftpd
start
5、添加系统用户（好像很重要，否则只能进入到匿名用户）
useradd -d {home目录} -s /bin/false {user}
passwd user (设密)
然后可以修改用户归属的组、目录、目录权限，就可以用特定用户登录ftp
6、在/etc/vsftpd.chroot_list 添加vsftpd用户名（没有此文件要新建一个）
7、用root向/home/ftp、各用户里添加文件
