以下为默认主配置文件的解释
# Example config file /etc/vsftpd/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
//允许使用匿名账户
#
# Uncomment this to allow local users to log in.
local_enable=YES
//允许使用本地系统账户
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
//允许本地账户写入
#
# 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
//默认的创建目录的反掩码
#
# 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
//是否允许匿名用户的上传
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES
//是否允许匿名账户创建，写入，修改文件
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES
//是否允许进入ftp目录的欢迎信息
#
# Activate logging of uploads/downloads.
xferlog_enable=YES
//启用上传和下载日志
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES
//从20端口传输数据
#
# 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
//更改上传文件的用户
#chown_username=whoever
//要更改的拥有者，（不可以是root）
#
# You may override where the log file goes if you like. The default is shown
# below.
#xferlog_file=/var/log/vsftpd.log
//日志的存储位置
#
# If you want, you can have your log file in standard ftpd xferlog format
xferlog_std_format=YES
//使用标准日志格式
#
# You may change the default value for timing out an idle session.
#idle_session_timeout=600
//控制会话连接超时时间
#
# You may change the default value for timing out a data connection.
#data_connection_timeout=120
//数据连接超时时间
#
# 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
//
切换到无权限状态时, 使用此用户
#
# 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
//是否启用
async ABOR
命令
#
# 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 格式上传
#ascii_download_enable=YES
//ascii 格式下载
#
# You may fully customise the login banner string:
#ftpd_banner=Welcome to blah FTP service.
//登录欢迎词
#
# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
//禁止Email作为密码
# (default follows)
#banned_email_file=/etc/vsftpd/banned_emails
//禁止Email作为密码的文件
#
# 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
//列表中的用户不能更改根目录
# (default follows)
#chroot_list_file=/etc/vsftpd/chroot_list
//不能更改根目录的用户的列表
#
# 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
//是否允许使用命令 ls -R
#
# 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
//以独立进程启动ftp服务
#
# This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6
# sockets, you must run two copies of vsftpd whith two configuration files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=YES
//
对 IPv6 接口进行监听
pam_service_name=vsftpd
//
用于指定 PAM 服务的名称
userlist_enable=YES
//是否启用userlist用户列表
tcp_wrappers=YES
//使用tcp_wrappers作为主机访问控制方式。
