一、安装
[list:93f3c4a2db]1.下载最新的稳定版vsftpd-1.2.1.tar.gz
2.卸载原有的rpm的vsftpd
rpm -e vsftpd
3.tar xvzf vsftpd-1.2.1.tar.gz
4.cd vsftpd-1.2.1
5.make
6.useradd nobody
7.mkdir /usr/share/empty
8.mkdir /var/ftp
9.useradd -d /var/ftp ftp
10.chown root.root /var/ftp
11.chmod og-w /var/ftp
说明：如果你象我一样原来有rpm的vsftp，只是卸载了，可以省略6-11步，如果原来没有安装vsftp，请按部就班。
12.make install
13.vi /etc/xinetd.d/vsftpd
把disable=yes改成no，保存退出。然后service xinetd restart，OK！新装的vsftp已经可以工作了！
说明：默认安装的vsftpd是以xinetd的方式启动的。你需要上述操作，一会儿，我们再来讲把它改成独立启动的服务。
14.ftp 127.0.0.1
输入用户名ftp，密码直接回车，OK！已经可以连接了！输入quit退出。然后重新ftp 127.0.0.1，输入本地用户和密码，却提示login faild！why?原来少一个本地用户认证的pam文件。
15.cp RedHat/vsftpd.pam /etc/pam.d/ftp（注意，没有这一步将不能使用本地用户登录！）
16.cp vsftpd.conf /etc/vsftpd.conf（现在，默认还是只能匿名用户登录）
17.vi /etc/vsftpd.conf
把anonmous_enable=YES改成NO(禁掉匿名链接，不安全）
把local_enable=YES前的注释去掉（打开本地用户连接的权限）
把write_enable=YES前的注释去掉（打开本地用户的写权限）
把local_umask=022前的注释去掉
service xinetd restart
18.再次测试
ftp 127.0.0.1
使用ftp用户空密码登录，将出现login faild
使用本地用户登录，OK！已经成功了！上传文件，也OK！[/list:u:93f3c4a2db]
这样是不是就完事儿了？不是，做一个FTP，我们通常还需要一些特殊要求：比如一个用户我只允许他下载，不允许他上传另一个用户可以下载也可以上传，但是他不能删除文件，不能给文件改名另外，我还需要我的FTP使用非常规的端口，限制下载的速度，还需要一个管理员用户。那怎么办？请看下面的部分！

三、附目
1.我的/etc/vsftpd.conf文件的内容
[quote:93f3c4a2db]# 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.
#
# 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=NO
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
anon_mkdir_write_enable=NO
#
# 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 turning on ascii_download_enable enables malicious remote parties
# to consume your I/O resources, by issuing the command "SIZE /big/file" in
# ASCII mode.
# These ASCII options are split into upload and download because you may wish
# to enable ASCII uploads (to prevent uploaded scripts etc. from breaking),
# without the DoS risk of SIZE and ASCII downloads. ASCII mangling should be
# on the client anyway..
ascii_upload_enable=YES
ascii_download_enable=YES

# You may fully customise the login banner string:
ftpd_banner=Welcome to Serv-U FTP serser. #(一个真实的慌言:em02:)

# 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_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.
