1、yum install vsftpd ,输入y确认安装

安装vsftpd

2.安装完成后配置vi /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).

#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 lightnear 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

userlist_deny=NO

local_root=/var/public_root

tcp_wrappers=YES

use_localtime=YES

 

3.增加账户

增加账户

这里设置的账户名为“cent”,密码为“cent”

1

 

2

[[email protected] ~]# useradd cent -s /sbin/nologin

 

[[email protected] ~]# passwd cent

4.编辑user_list文件,允许cent用户访问FTP

编辑user_list文件

5. 建立我们的根目录,并设置访问权限

[[email protected] ~]# mkdir /var/public_root

[[email protected] ~]# chown -R cent /var/public_root

[[email protected] ~]# chmod -R 755 /var/public_root

设置访问权限

6.开启vsftpd服务

[[email protected] ~]# service vsftpd start

开启服务

7.默认开启vsftp服务

[[email protected] var]# chkconfig vsftpd on

设置开机启动

8.在ftp目录下建立文件,打开ftp软件,测试,连接成功。

测试连接

测试连接2

如果服务器上安装了vsftpd,配置出错需要卸载vsftpd

1 [[email protected] ~]# rpm -aq vsftpd

vsftpd-2.0.5-16.el5_5.1 #此处是查找vsftpd的返回结果

1 [[email protected] ~]# rpm -e vsftpd-2.0.5-16.el5_5.1

#用rpm -e 查找结果 进行删除就ok了。 warning: /etc/vsftpd/user_list saved as /etc/vsftpd/user_list.rpmsave warning: /etc/vsftpd/ftpusers saved as /etc/vsftpd/ftpusers.rpmsave #删除时将备份vsftp的用户列表文件。

看下是否卸载了vsftpd,进行stop及start操作:

1 [[email protected] ~]# /sbin/service vsftpd stop

vsftpd: unrecognized service #找不到vsftpd

1 [[email protected] ~]# /sbin/service vsftpd start

vsftpd: unrecognized service #找不到vsftpd记住,在卸载vsftpd之前,先停止vsftpd。
