Ubuntu18.04搭建ftp服务器

  1. 如果之前安装过vsftpd,请先卸载 sudo apt-get remove --purge vsftpd
  2. 更新源列表: sudo apt-get update
  3. 安装vsftpd: sudo apt-get install vsftpd
  4. 判断vsftpd是否安装成功: sudo service vsftpd restart
  5. 新建”/home/test” 目录作为用户主目录: 

    打开终端窗口,输入”sudo mkdir /home/test” 回车,在输入”sudo ls 

    /home” 回车,有一个test目录,则用户目录创建成功。

  6. 新建用户test并设置密码:打开终端,输入”sudo useradd –d /home/test –s /bin/bash test” 回车,新建用户成功,在输入”sudo passwd test” 设置test用户的密码(输入两次) 回车,密码设置成功。

  7. 配置文件/etc/vsftpd.conf,具体配置文件如下

    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=NO
    # (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.
    pasv_enable=YES
    allow_writeable_chroot=YES
    pasv_address=公网ip地址
    pasv_min_port=50000
    pasv_max_port=50010
    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
    
    #
    # Uncomment this to indicate that vsftpd use a utf8 filesystem.
    #utf8_filesystem=YES
    local_root=/home/test
    

     

  8. 开放阿里云21端口并配置限制可用于被动FTP的端口范围,以确保有足够的可用连接

  9. 关闭防火墙 ufw diable

  10. 查看防火墙状态 ufw status   如果显示inactive,表明防火墙关闭成功
  11. 使用vim查看/etc/ftpusers文件中的内容                打开"终端窗口",输入"sudo vim /etc/ftpusers" 回车-->打开这个文件后,检查是否有test这个用户名,若没有,就直接退出。若有就删除test用户名,因为这个文件中记录的是不能访问FTP服务器的用户清单。
  12. 使用FileZilla工具测试连接

配置普通用户访问对ftp服务的访问权限

 

  1. useradd -d /home/test yuanxun      //添加用户yuanxun,限定访问目录/home/test
  2. passwd yuanxun                    //设置密码
  3. vi /etc/passwd 文件里能看到刚刚创建的用户名和可访问目录信息
  4. 使用FileZilla测试该用户对此文件夹的读写权限
