# 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?

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## The target log file can be vsftpd_log_file or xferlog_file.# This depends on setting xferlog_std_format parameterxferlog_enable=YESxferlog_file=/main/var/log/vsftpd.log## 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.

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=YESascii_download_enable=YES## You may fully customise the login banner string:#ftpd_banner=Welcome to blah FTP service.## You may specify a file of disallowed anonymous e-mail addresses.

This directive cannot be used in conjunction# with the listen_ipv6 directive.listen=YES## This directive enables listening on IPv6 sockets.

anonymous_enable=NO   设定不允许匿名访问local_enable=YES   设定本地用户可以访问。注：如使用虚拟宿主用户，在该项目设定为NO的情况下所有虚拟用户将无法访问。chroot_list_enable=YESxferlog_file=/var/log/vsftpd.log 设定vsftpd的服务日志保存路径。注意，该文件默认不存在。必须要手动touch出来ascii_upload_enable=YESascii_download_enable=YES  设定支持ASCII模式的上传和下载功能。pam_service_name=vsftpd   PAM认证文件名。PAM将根据/etc/pam.d/vsftpd进行认证以下这些是关于Vsftpd虚拟用户支持的重要配置项目。默认vsftpd.conf中不包含这些设定项目，需要自己手动添加配置。guest_enable=YES   设定启用虚拟用户功能。guest_username=ftp   指定虚拟用户的宿主用户。-CentOS中已经有内置的ftp用户了user_config_dir=/etc/vsftpd/vuser_conf 设定虚拟用户个人vsftp的配置文件存放路径。存放虚拟用户个性的配置文件(配置文件名=虚拟用户名)
