4。配制VSFTP，FVSFTP的运行有两种模式，一种是stardard "initd模式，另外一种是xinetd模式，上面我们所说的就是stardard initd运行模式。两种模式运行机制不是相同的，stardard initd模式，适合专业FTP，且FTP总是一直有人访问，占用资源也是比较大，如果您的FTP总是有人访问和登入。就要用这种模式。如果您的FTP访问人数比较小，建议您用xinetd模式。Xinetd模式，是当用户请求时，vsftpd才会启动。
不同的环境，当然得用不同的启动模式。
如果想了解更多的，请在本帖后面跟帖，我会慢慢补充xinetd模式，以及虚拟用户如何设置方面的问题。
1]我们主要把vsftp的配制文件改一下就行了。配制文件在/etc/vsftpd/vsftpd.conf，用您喜欢的编辑器打开。请参考下面的配制文件。

   # Example config file /etc/vsftpd.conf 
# 
# The default compiled in settings are very paranoid. This sample file 
# loosens things up a bit, to make the ftp daemon more usable. 
# 
# Allow anonymous FTP? 
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 
# 
# 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 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_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 
pam_service_name=vsftpd 
userlist_enable=YES 
#enable for standalone mode 
listen=YES 
tcp_wrappers=YES
2]更改完配制文件后，我们可以用下面的命令来重启VSFTPD服务器 
[root@linuxsir001 root]# /etc/init.d/vsftpd restart 
关闭 vsftpd： [ 确定 ] 
为 vsftpd 启动 vsftpd： [ 确定 ] 
[root@linuxsir001 root]#
