    系统信息 阿里云ubuntu14

    第一步:下载安装

    sudo apt-get install vsftpd

    启动sudo service vsftpd start

    第二步:修改配置文件

    cat /etc/vsftpd.conf
    # 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
    #
    # Run standalone with IPv6?
    # Like the listen parameter, except vsftpd will listen on an IPv6 socket
    # instead of an IPv4 one. This parameter and the listen parameter are mutually
    # exclusive.
    #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_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
    # This option specifies the location of the RSA key to use for SSL
    # encrypted connections.
    rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
    root@iZ94ytpcjuhZ:/mnt/yd.game.deetaa.com# 
    View Code

    #vi /etc/vsftpd.conf

    anonymous_enable=YES “改为 “anonymous_enable=NO

    local_enable=YES

    write_enable=YES

    chroot_local_user=YES

    chroot_list_enable=YES

    chroot_list_file=/etc/vsftpd.chroot_list

    第三步:

    修改 etc/shell

    检查下,我的是usr/sbin/nologin,加入进去;

    如下

    root@iZ94ytpcjuhZ:/# vi etc/shells

    # /etc/shells: valid login shells
    /bin/sh
    /bin/dash
    /bin/bash
    /bin/rbash
    /usr/bin/screen
    /usr/sbin/nologin

    第四步:

    增加组sudo groupadd ftpgroup

    增加用户:

        sudo useradd -g ftpgroup -d /mnt -s /usr/sbin/nologin -M comm

               记得加上-s 参数

    顺便:

          -c:加上备注文字,备注文字保存在passwd的备注栏中。  
          -d:指定用户登入时的启始目录。
          -D:变更预设值。
          -e:指定账号的有效期限,缺省表示永久有效。
          -f:指定在密码过期后多少天即关闭该账号。
          -g:指定用户所属的起始群组。 
          -G:指定用户所属的附加群组。
          -m:自动建立用户的登入目录。
          -M:不要自动建立用户的登入目录。
          -n:取消建立以用户名称为名的群组。
          -r:建立系统账号。
          -s:指定用户登入后所使用的shell。
          -u:指定用户ID号

          我这边测试,如果不加-s参数,登录会报错530,VI ect/shells 可以看到类似:

      zhonghua:x:1006:1006::/mnt:

      正常的话应该是zhonghua:x:1006:1006::/mnt:/usr/sbin/nologin

          密码 passwd comm

    第五步: 

        root@iZ94ytpcjuhZ:/# vi /etc/vsftpd.chroot_list

        hulei
        lzyong
        lsn
        zhonghua

        comm

    第六步: service vsftpd restart
