创建一个专用的FTP数据存储目录：
# mkdir /ftpserver

# vi /etc/vsftpd/vsftpd.conf
设置vsftpd为standalone工作模式
listen=YES
tcp_wrappers=YES

启用本地用户：
local_enable=YES

禁用匿名用户：
anonymous_enable=NO
#anon_upload_enable=YES
#anon_mkdir_write_enable=YES

更改FTP默认监听端口21：
添加
##Set the listen_port
Listen_port=5200

设置FTP的PASV模式传输端口，以配合防火墙通过PASV模式传输数据：
添加
##set the pasv ports
port_enable=NO
pasv_enable=YES
pasv_min_port=10021
pasv_max_port=10025

设置FTP服务器最大的并发连接数,默认值为0，表示不限最大连接数。
添加
max_clients=1000

设置每个IP地址最大的并发连接数目，默认值为0，表示不限制。
添加
max_per_ip=10

启用锁定主目录用户名单功能：
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd.chroot_list
# touch /etc/vsftpd.chroot_list

启用特定用户独立配置文件功能：
添加
##set the user's private config
user_config_dir=/etc/vsftpd/user_config/
# mkdir /etc/vsftpd/user_config/

创建一个FTP用户，将该用户的主目录指向到/ftpserver，并使其不能登陆shell：
# useradd jacky -d /ftpserver/jacky -s /sbin/nologin
# passwd jacky

锁定jacky用户的主目录
# vi /etc/vsftpd.chroot_list
添加
jacky

创建jacky用户的独立配置文件：
# cd /etc/vsftpd/user_config/
# vi jacky
##Allow this user download?
#download_enable=YES

##Uncomment this to enable any form of FTP write command,such as "STOR,DELE,RNFR,RNTO,MKD,RMD,APPE,SITE ..."
#write_enable=YES

##If you set the "write_enable=YES",but don't want to allow "rename or delete ..."
##You can open "cmds_allowed",and remove the command which you don't allow.
##"delete" = "DELE,RMD" ; "rename" = "RNFR,RNTO" ; "mkdir" = "MKD"
#cmds_allowed=ABOR,ACCT,ALLO,APPE,CDUP,CWD,DELE,EPRT,EPSV,FEAT,HELP,LIST,MDTM,MKD,MODE,NLST,NOOP,OPTS,PASS,PASV,PORT,PWD,QUIT,REIN,REST,RETR,RMD,RNFR,RNTO,SITE,SIZE,SMNT,STAT,STOR,STOU,STRU,SYST,TYPE,USER,XCUP,XCWD,XMKD,XPWD,XRMD,BYE

##Set the max rate for this user,"Bytes/s".
#local_max_rate=204800

##Set the root directory for this user.
#local_root=

使jacky用户仅具有下载、上传和创建目录的权限，而没有删除和重命名的权限：
download_enable=YES
write_enable=YES
cmds_allowed=ABOR,ACCT,ALLO,APPE,CDUP,CWD,EPRT,EPSV,FEAT,HELP,LIST,MDTM,MKD,MODE,NLST,NOOP,OPTS,PASS,PASV,PORT,PWD,QUIT,REIN,REST,RETR,SITE,SIZE,SMNT,STAT,STOR,STOU,STRU,SYST,TYPE,USER,XCUP,XCWD,XMKD,XPWD,XRMD,BYE
限制jacky用户的最大下载速度为200KB左右
local_max_rate=204800

重启vsftpd以使配置生效：
# /etc/init.d/vsftpd restart

修改防火墙以使FTP通过：
# vi /etc/sysconfig/iptables
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5200 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 10021 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 10022 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 10023 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 10024 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 10025 -j ACCEPT

重启防火墙以使策略生效：
# /etc/init.d/iptables restart

OK! The end.

PS（根据实际需要）:
开放root用户的FTP权限：
# vi /etc/vsftpd.ftpusers
#root
# vi /etc/vsftpd.user_list
#root

禁止jacky用户的FTP权限
# vi /etc/vsftpd.ftpusers
添加
jacky
# vi /etc/vsftpd.user_list
添加
jacky

====================================================================

# 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.
listen=YES
#
# 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).
anonymous_enable=YES
#
# 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
anon_root=/var/www/public/
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES
#
# Activate logging of uploads/downloads.
xferlog_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. 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
#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:
#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().
#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=/var/run/vsftpd
#
# 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/vsftpd.pem
