linux 下安装 vsftp 图解

VSFTPD的文件结构是很简洁的，主要包括：
/usr/sbin/local/vsftpd(tar方式) /usr/sbin/vsftpd(rpm方式)VSFTPD主程序
/etc/rc.d/init.d/vsftpd ---- 启动脚本(rpm安装方式才会有)
/etc/vsftpd.conf(tar方式)/etc/vsftpd/vsftpd.conf(rpm方式)主配置文件
/etc/pam.d/vsftpd(rpm安装方式)---- PAM认证文件(注：tar方式，需手动复制)
/etc/vsftpd.ftpusers(rpm安装方式才有)---- 禁止使用VSFTPD的用户列表文件
/etc/vsftpd.user_list(rpm方式才有)---- 禁止或允许使用VSFTPD的用户列表

1.安装
#rpm -ivh vsftpd-2.0.1-5.i386.rpm
2.配置/etc/vsftpd/vsftpd.conf

# 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.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
########是否允许匿名用户访问
anonymous_enable=NO
#
# Uncomment this to allow local users to log in.
########否允许本地用户登陆
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
########设置全局是否可写
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.
##########是否允许匿名用户上传文件
anon_upload_enable=NO
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
##########是否允许匿名用户创建目录
anon_mkdir_write_enable=NO
###########如果设为YES，匿名登入者会被允许更多于上传与建立目录之外的权限，譬如删除
anon_other_write_enable=NO
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
###########进入目录时显示此目录下由message_file选项指定的文本文件
dirmessage_enable=YES
#
# Activate logging of uploads/downloads.
#############使用上传/下载日志,日志文件默认为/var/log/vsftpd.log
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
########匿名用户上传所有者指定功能需要与下一参数配合使用
chown_uploads=YES
########指定匿名用户上传文件的所有者
chown_username=root
#
# You may override where the log file goes if you like. The default is shown
# below.
############保存日志文件
xferlog_file=/usr/app/log/vsftpd.log
#
# If you want, you can have your log file in standard ftpd xferlog format
#########日志使用标准xferlog格式
xferlog_std_format=NO
#
# 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.
##########管控是否可用ASCII 模式下载。默认值为NO
#ascii_upload_enable=YES
#ascii_download_enable=YES
#
# You may fully customise the login banner string:
########login时的欢迎信息
ftpd_banner= Welcome......
#
# 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().
###########决定vsftpd用户可以执行chroot操作，即改变其家目录操作
chroot_list_enable=NO
#########该文件中列举了可以执行chroot操作的用户名单
chroot_list_file=/etc/vsftpd/chroot_list
###########决定vsftpd的本地用户只能在其家目录
chroot_local_user=YES
##########设置用户登录后所在的目录
local_root=/usr/ftp_home
#
# 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 st
