ubuntu 15.10 安装vsftpd

第一步：安装vsftpd

sudo apt-get install vsftpd

第二步：配置

sudo vi /etc/vsftpd.conf

注销掉，关闭匿名访问

#anonymous_enable=YES

去掉注销，#让本地账号可以访问，比如root，等系统登录账号

local_enable=YES 

write_enable=YES

第三步：如果你需要让root可以访问需要执行第三步

sudo vi /etc/ftpusers

把root去掉

第四步：增加一个访问账号

增加一个ftpgroup用户组

sudo groupadd ftpgroup

增加用户ftpuser并设置其目录为/ftp/ftpuser(可以修改，但是必须创建该文件夹)

sudo useradd -g ftpgroup -d /ftp/ftpuser -M ftpuser

如果上面的/ftp/ftpuser没有被创建，即需要创建该文件夹

sudo mkdir /ftp

sudo mkdir /ftp/ftpuser

用户必须拥有权限才可以访问，赋予访问/ftp/ftpuser的权限

sudo chmod 777 /ftp/ftpuser

第五步：设置ftpuser密码

sudo passwd ftpuser
第六步： 删除/etc/pam.d/vsftpd  文件。
这是因为ubuntu启用了PAM,所在用到vsftp时需要用到 /etc/pam.d/vsftpd 这个文件（默认源码安装的不会有这个文件），因此除了匿名用户外本地用户无法登录。所以只要删除了就可以了，否则 530 login incorrect 错误。

第七步：重启vsftpd

sudo restart vsftpd

第二种安装：
###############################################################################################################################

1，更新源列表
      打开"终端窗口"，输入"sudo apt-get update"-->回车-->"输入当前登录用户的管理员密码"-->回车,就可以了。如果不运行该命令，直接安装vsftpd,会出现"有 几个软件包无法下载，您可以运行apt-get update------"的错误提示，导致无法安装。

2，安装vsftpd
     打开"终端窗口"，输入"sudo apt-get install vsftpd"-->回车-->安装完成。

3，判断vsftpd是否安装成功
     打开"终端窗口"，输入"sudo service vsftpd restart"重启vsftpd服务-->回车-->vsftpd处于运行状态，说明安装成功。

4，新建"/home/uftp"目录作为用户主目录

      打开"终端窗口"，输入"sudo mkdir /home/uftp"-->回车-->输入"sudo ls /home"-->回车-->有一个uftp目录，目录新建成功。

5，新建用户uftp并设置密码
      打开"终端窗口"，输入"sudo useradd -d /home/uftp -s /bin/bash uftp"-->回车-->用户新建成功-->输入"sudo passwd uftp"设置uftp用户的密码-->回车-->输入两次密码-->回车-->密码设置成功。

6，使用gedit修改配置文件/etc/vsftpd.conf

      打开"终端窗口"，输入"sudo gedit /etc/vsftpd.conf"-->回车-->打开了vsftpd.conf文件，向文件中添加"userlist_deny=NO

userlist_enable=YES userlist_file=/etc/allowed_users"和"seccomp_sandbox=NO"-->使文件中的"local_enable=YES"-->保存

7，使用gedit新建/etc/allowed_users文件

      打开"终端窗口"，输入"sudo gedit /etc/allowed_users"-->回车-->输入uftp-->保存， 文件创建成功。

 
8，使用gedit查看/etc/ftpusers文件中的内容

      打开"终端窗口"，输入"sudo gedit /etc/ftpusers"-->回车-->打开这个文件后，看一看有没有uftp这个用户名，如果没有，就直接退出。如果有就删除uftp,因为这个文件中记录的是不能访问FTP服务器的用户清单。

9，使用winscp登录FTP服务器

       下载安装WinSCP，运行WinSCP-->输入IP、用户名、密码-->保存-->勾选"保存密码"-->确定-->登录-->登录成功。

10，附vsftpd.conf 配置文件

     # 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.
#
#
# Run standalone?  vsftpd can run either from an inetd or as a standalone
# daemon started from an initscript.
listen=YES
#
# 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.
#listen_ipv6=YES
#
# Allow anonymous FTP? (Disabled by default).
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=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
#
# If enabled, vsftpd will display directory listings with the time
# in  your  local  time  zone.  The default is to display GMT. The
# times returned by the MDTM FTP command are also affected by this
# option.
use_localtime=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.
# 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.
# 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 restrict local users to their home directories.  See the FAQ for
# the possible risks in this before using chroot_local_user or
# chroot_list_enable below.
#chroot_local_user=YES
#
# 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().
# (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
#
# Customization
#
# Some of vsftpd's settings don't fit the filesystem layout by
# default.
#
# This option should be the name of a directory which is empty.  Also, the
# directory should not be writable by the ftp user. This directory is used
# as a secure chroot() jail at times vsftpd does not require filesystem
# access.
secure_chroot_dir=/var/run/vsftpd/empty
#
# This string is the name of the PAM service vsftpd will use.
pam_service_name=vsftpd
#
# This option specifies the location of the RSA certificate to use for SSL
# encrypted connections.
rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
ssl_enable=NO


userlist_deny=NO
userlist_enable=YES
userlist_file=/etc/allow_users
seccomp_sandbox=NO
