VSFTP是一个基于GPL发布的类Unix系统上使用的FTP服务器软件，它的全称是Very Secure FTP 从此名称可以看出来，编制者的初衷是代码的安全。
下面说说在CentOS 6.5_64位系统下安装VSFTP步骤
1.查看linux系统版本和内核信息
[root@vmware1 ~]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
[root@vmware1 ~]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
2.关闭防火墙和selinux。
[root@vmware1 ~]# /etc/init.d/iptables stop
[root@vmware1 ~]# chkconfig iptables off
[root@vmware1 ~]# setenforce 0
3.安装vsftp软件包。
[root@vmware1 ~]# yum install -y vsftpd
先备份vsftpd的默认配置文件；
[root@vmware1 ~]# cd /etc/vsftpd/
[root@vmware1 vsftpd]# cp vsftpd.conf vsftpd.conf.bak
4.清空vsftpd.cong默认的内容。
root@vmware1 vsftpd]# >vsftpd.conf
5.修改后的内容为：
[root@vmware1 vsftpd]# cat 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
#
# 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 parameter
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
#
# The name of log file when xferlog_enable=YES and xferlog_std_format=YES
# WARNING - changing this filename affects /etc/logrotate.d/vsftpd.log
#xferlog_file=/var/log/xferlog
#
# Switches between logging into vsftpd_log_file and xferlog_file files.
# NO writes to vsftpd_log_file,YES to xferlog_file
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 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_local_user=YES
#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
#
# 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=YES
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES
11.重启vsftpd，然后查看端口是否开启。
[root@vmware1 ~]# service vsftpd restart
关闭 vsftpd： [确定]
为 vsftpd 启动 vsftpd： [确定]
这样就可以用系统原有用户进行登陆了
[root@vmware1 ~]# netstat -anpt | grep vsftpd
tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN 2191/vsftpd
12.在本地ftp服务器登陆测试。
[root@vmware1 ~]# ftp 127.0.0.1
Connected to 127.0.0.1 (127.0.0.1).
220 (vsFTPd 2.2.2)
Name (127.0.0.1:root): lhc
331 Please specify the password.

230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> dir
227 Entering Passive Mode (127,1,149,179).
150 Here comes the directory listing.
226 Directory send OK.
ftp> mkdir hello
257 "/hello" created
ftp> dir

150 Here comes the directory listing.

到此为止，VSFTP搭建完成，实验结束。
