篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了ftp搭建记录相关的知识，希望对你有一定的参考价值。

1.安装vsftpd的rpm包

rpm -ivh vsftpd-2.0.5-16.el5_4.1.i386.rp

2.ftp命令

service vsftpd start

service vsftpd stop

service vsftpd restar

rpm -qa |grep vsftp -----查看版本

rpm -e 版本名称 ----卸载命令

3.ftp配置

/etc/vsftpd/vsftpd.conf

/etc/vsftpd/user_list

/etc/vsftpd/ftpusers

ftpusers 该文件用来指定那些用户不能访问ftp服务器。

user_list 该文件用来指示的默认账户在默认情况下也不能访问ftp

vsftpd.conf vsftpd的主配置文件

4.ftp相关配置参数

内容（根据自身情况使用）:

anonymous_enable=NO #不允许匿名用户登陆

local_enable=YES #vsftpd所在系统的用户可以登录

vsftpd

write_enable=YES #允许使用任何可以修改文件系统的FTP的指令

local_umask=002 #匿名用户新增文件的umask数值

anon_upload_enable=NO #匿名用户不可以上传文件

anon_mkdir_write_enable=NO #匿名用户不可以修改文件

xferlog_enable=YES #启用一个日志文件，用于详细记录上传和下载。

use_localtime=YES #使用本地时间而不是

GMT

vsftpd_log_file=/var/log/vsftpd.log #vsftpd日志存放位置

dual_log_enable=YES #用户登陆日志

connect_from_port_20=YES #开启20端口

xferlog_file=/var/log/xferlog #记录上传下载文件的日志

xferlog_std_format=YES #记录日志使用标准格式

idle_session_timeout=600 #登陆之后超时时间60秒，登陆之后，一分钟不操作，就会断开连接。

chroot_local_user=YES #用于指定用户列表文件中的用户,是否允许切换到上级目录

listen=YES #开启监听

pam_service_name=vsftpd.vu #验证文件的名字

userlist_enable=YES #允许由userlist_file指定文件中的用户登录FTP服务器

tcp_wrappers=YES #支持tcp_wrappers,限制访问(/etc/hosts.allow,/etc/hosts.deny)

guest_enable=YES #起用虚拟用户

guest_username=taokey #虚拟用户名

#user_config_dir=/etc/vsftpd/vsftpuser #虚拟用户配置文件路径

local_root=/usr/local/ftpFiles #自定义ftp上传路径（注意文件夹权限）

pasv_min_port=35000

pasv_max_port=45000

pasv_enable=YES

pasv_promiscuous=YES

anon_other_write_enable=YES

更具需要修改对应的值关闭并保存配置文件，重启vsftpd服务。

5.vsftpd.conf文件

# 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).
anonymous_enable=NO
#
# Uncomment this to allow local users to log in.
# When SELinux is enforcing check for SE bool ftp_home_dir
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.
# When SELinux is enforcing check for SE bool allow_ftpd_anon_write, allow_ftpd_full_access
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=hf
#
# You may override where the log file goes if you like. The default is shown
# below.
#xferlog_file=/var/log/xferlog
#
# If you want, you can have your log file in standard ftpd xferlog format.
# Note that the default log file location is /var/log/xferlog in this case.
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. The vsftpd.conf(5) man page explains
# the behaviour when these options are disabled.
# 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. Ifroot_list_enablechroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
# (Warning! chroot‘ing can be very dangerous. If using chroot, make sure that
# the user does not have write access to the top level directory within the
# 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=NO
#
# This directive enables listening on IPv6 sockets. By default, listening
# on the IPv6 "any" address (::) will accept connections from both IPv6
# and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
# sockets. If you want that (perhaps because you want to listen on specific
# addresses) then 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
local_root=/home/hf1/
chroot_local_user=YES
anon_root=/home/hf2/
