FTP 是File Transfer Protocol（文件传输协议）的英文简称，而中文简称为“文本传输协议”。用于Internet上的控制文件的双向传输。

在FTP的使用当中，用户经常遇到两个概念："下载"（Download）和"上传"（Upload）。"下载"文件就是从远程主机拷贝文件至自己的计算机上；"上传"文件就是将文件从自己的计算机中拷贝至远程主机上。用Internet语言来说，用户可通过客户机程序向（从）远程主机上传（下载）文件。

### 1.安装vsftpd服务器 ###

sudo apt-get install vsftpd

### 2.配置vsftpd.conf文件 ###

sudo vi /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=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.
    listen_ipv6=YES
    #
    # Allow anonymous FTP? (Disabled by default).
    #这个是设置是否允许匿名登录ftp服务器，不允许。
    anonymous_enable=NO
    #
    # Uncomment this to allow local users to log in.
    #是否允许本机用户登录
    local_enable=YES
    #
    # Uncomment this to enable any form of FTP write command.
    #允许上传文件到ftp服务器
    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) 允许chroot_list文件中配置的用户登录此ftp服务器。
    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
    
    #
    # Uncomment this to indicate that vsftpd use a utf8 filesystem.
    #utf8_filesystem=YES
    #配置ftp服务器的上传下载文件所在的目录。
    local_root=/home/python/ftpfile
    #this directory is for ftp server to save  download or upload data

### 3。给ftp服务器配置使用用户等信息 ###

![70][]

将允许使用此ftp服务器的用户名称放到chroot\_list文件中。比如添加了python，robot用户。

### 4.给ftp服务器创建文件存放目录（要跟vsftpd.conf中配置路径一致） ###

![70 1][]

### 5.配置后重启ftp，并且测试 ###

![70 2][]

在ubuntu命令行模式下，登录ftp服务器

python@ubuntu:~$ ftp 192.168.1.100
    Connected to 192.168.1.100.
    220 (vsFTPd 3.0.3)
    Name (192.168.1.100:python): python
    331 Please specify the password.
    Password:
    230 Login successful.
    Remote system type is UNIX.
    Using binary mode to transfer files.
    ftp>

使用xftp5工具远程连接该ftp服务器进行 文件的上传下载。
