编辑vsftpd配置文件

sudo vim /etc/vsftpd/vsftpd.conf

使用如下配置

# 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.#local_root=/ftpfile#anon_root=/ftpfileuse_localtime=YES# Allow anonymous FTP? (Beware - allowed by default if you comment this out).anonymous_enable=NO## 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## The target log file can be vsftpd_log_file or xferlog_file.# This depends on setting xferlog_std_format parameterxferlog_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.

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 blah FTP service.## You may specify a file of disallowed anonymous e-mail addresses.

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## 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## This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6# sockets, you must run two copies of vsftpd with two configuration files.# Make sure, that one of the listen options is commented !!#listen_ipv6=YESpam_service_name=vsftpduserlist_enable=YEStcp_wrappers=YESpasv_enable=YESpasv_min_port=61001pasv_max_port=62000

vsftpd常用命令

配置防火墙

编辑iptables

sudo vim /etc/sysconfig/iptables

添加如下规则

#vsftpd-A INPUT -p TCP --dport 61001:62000 -j ACCEPT-A OUTPUT -p TCP --sport 61001:62000 -j ACCEPT-A INPUT -p TCP --dport 20 -j ACCEPT-A OUTPUT -p TCP --sport 20 -j ACCEPT-A INPUT -p TCP --dport 21 -j ACCEPT-A OUTPUT -p TCP --sport 21 -j ACCEPT

保存退出后重启防火墙

sudo service iptables restart

编辑selinux

打开selinux配置文件

sudo vim /etc/selinux/config

编辑参数

SELINUX=disable#SELINUX=enforcing

使其成效

sudo setenforce 0
