一、安装并检查

  1. sudo apt-get install vsftpd -y
  2. sudo vsftpd -v

二、修改服务器配置

sudo vim /etc/vsftpd.conf

配置内容如下：
# 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.
# 是否开启监听ipv4和ipv6数据
listen=NO
#
# This directive enables listening on IPv6 sockets. By default, listening
# on the IPv6 "any" address (::) will accept connections from both IPv6
# and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
# sockets. If you want that (perhaps because you want to listen on specific
# addresses) then you must run two copies of vsftpd with two configuration
# files.
# 是否开启监听ipv6数据
listen_ipv6=YES
#
# Allow anonymous FTP? (Disabled by default).
# 是否允许匿名登陆，无需密码
anonymous_enable=NO
#
# Uncomment this to allow local users to log in.
# 是否允许本地用户登录
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
# 是否允许登陆者上传文件, 如果需要上传文件可开启
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)
# 设置本地用户默认要减免的权限
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.
# 目录消息，能够给远程登陆的用户发送目录
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.
# 服务器所展示的目录将随着本地时间而改变
use_localtime=YES
#
# Activate logging of uploads/downloads.
# 开启上传下载的日志记录
xferlog_enable=YES
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
# 确认连接传输的端口号为20
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.
# 日志文件存放位置
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.
# 日志文件采用标准格式
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:
# 在使用shell时登陆那么会发送欢迎语
ftpd_banner=Welcome to blah 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().
# (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)
# 对本地用户是否实施限制
#chroot_local_user=YES
# 开启限制白名单
#chroot_list_enable=YES
# (default follows)
# 白名单路径，若无这个文件需要自己创建
#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.
# 此处ubuntu的系统需要改为ftp
pam_service_name=ftp
#
# 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
rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
ssl_enable=NO

# Uncomment this to indicate that vsftpd use a utf8 filesystem.
# 编码统一为utf8编码，可以识别中文，防止乱码
utf8_filesystem=YES

# 本地用户默认访问的目录
local_root=/home/ftpuser

# Ftp服务器的工作模式，此时为被动模式， 如果设置port_enable=YES,就表示主动模式
pasv_enable=YES
# 在PASV模式下，建立数据传输所可以使用port范围的下界
pasv_min_port=6000
# 在PASV模式下，建立数据传输所可以使用port范围的上界，把端口范围设在比较高的一段范围内，比如50000-60000，将有助于安全性的提高。
pasv_max_port=7000
# 解决500 OOPS: vsftpd: refusing to run with writable root inside chroot ()
allow_writeable_chroot=YES

三、新建FTP用户

sudo mkdir /home/ftpuser
sudo useradd ftpuser -d /home/ftpuser -m
sudo passwd ftpuser
sudo chmod 777 -R /home/ftpuser
sudo usermod -s /sbin/nologin ftpuser

四、重启FTP服务

sudo systemctl start vsftpd
sudo systemctl stop vsftpd
sudo systemctl restart vsftpd

五、开启端口
