Ubuntu安装vsftp软件
1.更新软件源
首先须要更新系统的软件源，便捷工具下载地址：http://help.aliyun.com/manual?spm=0.0.0.0.zJ3dBU&helpId=1692
2.安装vsftp
使用apt-get命令安装vsftp
#apt-get install vsftpd -y
3.加入�ftp帐号和文件夹
先检查一下nologin的位置，通常在/usr/sbin/nologin或者/sbin/nologin下。
使用以下的命令创建帐户，该命令指定了/alidata/www/wwwroot为用户pwftp的家文件夹，您能够自定义帐户名和文件夹：
#useradd -d /ftpdata -s /sbin/nologin pwftp
改动该帐户password:
#passwd pwftp
改动指定文件夹的权限
#chown -R pwftp.pwftp /ftpdata
4.配置vsftp
编辑vsftp配置文件，命令例如以下：
#vi /etc/vsftpd.conf
将配置文件里”anonymous_enable=YES “改为 “anonymous_enable=NO”
取消例如以下配置前的凝视符号：
local_enable=YES
write_enable=YES
chroot_local_user=YES
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd.chroot_list
保存退出
编辑/etc/vsftpd.chroot_list文件，将ftp的帐户名加入�进去，保存退出
5.改动shell配置
vi编辑/etc/shells，假设该文件中没有/usr/sbin/nologin或者/sbin/nologin（详细看当前系统配置）则追加进去
6.重新启动vsftp服务并測试登录
使用命令启动vsftp服务：
#service vsftpd restart
然后用帐号pwftp測试下能否够登陆ftp。文件夹是/alidata/www/wwwroot。

另外给大家贴出vsftpd.conf配置文件供大家參考，測试能够使用的哦
# 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=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 #pam__service_name=vsftpd userlist_enable=NO # 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 szlady.com FTP service. # # You may specify a file of disallowed anonymous e-mail addresses.

See the FAQ for # the possible risks in this before using chroot_local_user or # chroot_list_enable below. chroot_local_user=NO # # 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 # # Debian customization # # Some of vsftpd's settings don't fit the Debian filesystem layout by # default. These settings are more Debian-friendly. # # This option should be the name of a directory which is empty. Also, the # directory should not be writable by the ftp user.
