Linux搭建下VSFTP服务器步骤

1。boris@borisPC:~$ sudo apt-get install vsftpd
2。boris@borisPC:~$ sudo gedit /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.
#服务器以standalong模式运行,这样可以进行下面的控制
listen=YES

#匿名用户的传输比率(b/s)
anon_max_rate=51200

#本地用户的传输比率(b/s)
local_max_rate=512000

#可接受的最大client数目
max_clients=100

#每个ip的最大client数目
max_per_ip=5

#
# 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).
#接受匿名用户
anonymous_enable=YES

#匿名用户login时不询问口令
no_anon_password=YES

#
# Uncomment this to allow local users to log in.
#接受本地用户
local_enable=YES
#本地用户login後所在目录
local_root=/home/ftp

#可以上传(全局控制).若想要匿名用户也可上传则需要设置anon_upload_enable=YES,若想要匿名用户可以建立目录则需要anon_mkdir_write_enable=YES.这里禁止匿名用户上传,所以不设置这两项.
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)

#本地用户上传文件的umask
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.
#使用上传/下载日志,日志文件默认为/var/log/vsftpd.log,可以通过xferlog_file选项修改
xferlog_enable=YES

#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES
tcp_wrappers=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
#日志使用标准xferlog格式
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:
#login时的欢迎信息
ftpd_banner=Welcome to newfield 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.
#用户将被chroot在登录後所在目录中
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().
#设置为YES则下面的控制有效
#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
#
#
# 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=/home/ftp

#
# 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/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

3。boris@borisPC:~$ sudo gedit /etc/vsftpd.user_list
boris
anonymous
4.sudo chmod 777 /home/ftp/
sudo chown -R boris:root /home/ftp
5.boris@borisPC:~$ sudo /etc/init.d/vsftpd restart

Vsftpd虚拟路径设置
要解决的问题
假定我们的ftp的默认目录是/home/ftp，我们想把/media/hda5/download文件夹，映射到/home/ftp目录中

解决方法
首先在/home/ftp目录中建一个目录

sudo mkdir /home/ftp/virtual
然後执行mount命令

sudo mount --bind /media/hda5/download /home/ftp/virtual
这样就OK了。
