前言
本文是根据实践而来，最主要是帮助新手知道怎么自架FTP服务器，本文也可以说是一个简单的使用例子；但不会把ProFTPD的所有文档都详细说明；也就是说简单的安装和配置，以及最简单的使用。让不懂ProFTPD的弟兄，比着“瓢”也能画出“葫芦”。至于哪个FTP服务器程序更好，我想都是好的，只要会用就行；vsftpd 现在很流行；但ProFTPD也是一种选择... ...
1、什么是ProFTPD；
ProFTPD 是一个FTP服务器程序，和vsftpd、wuftp 类似的FTP服务器，他们最终实现功能和目的都是一样的，都是为了传输文件；
2、ProFTPD的编译和安装；
2.1、ProFTPD的下载；
ProFTPD的主页： http://www.proftpd.org 本教程选用版本： proftpd-1.3.0rc3.tar.gz 下载地址：
ftp://ftp.proftpd.org/distrib/source/ http://www.proftpd.org/download.html
2.2、编译安装；
编译安装时得用编译环境，比如需要gcc，如果少什么包，您可以在系统安装盘中找到；或者在线升级也行；现在大多的发行版都有支持在线升级的软件包管理工具；比如RPM的系统有yum和apt可用，debian有apt可用 ... ... 另外Proftpd 的用户认证是通过MySQL(和PHP搭配之最佳组合)数据库来实现的，我们也得把MySQL(和PHP搭配之最佳组合)数据库服务器也得安装上吧；这个不详细说了，您自己看着办吧；
我们想把ProFTPD 安装在 /opt/proftpd 目录中，我们把软件下载到 root用户的家目录中，因为安装软件需要 root权限，如果您在普通用户下执行编译是，到make install 这步，得通过su命令切换到root用户，然后执行 make install ； [root@localhost ~]# pwd /root [root@localhost ~]# ls proftpd-1.3.0rc3.tar.gz 解压、编译、安装
[root@localhost ~]# tar zxvf proftpd-1.3.0rc3.tar.gz [root@localhost ~]# cd proftpd-1.3.0rc3 [root@localhost proftpd-1.3.0rc3]#./configure --with-modules=mod_sql:mod_sql_MySQL(和PHP搭配之最佳组合):mod_quotatab:mod_quotatab_sql \ --with-includes=/usr/include/MySQL(和PHP搭配之最佳组合) \ --with-libraries=/usr/lib/MySQL(和PHP搭配之最佳组合) \ --prefix=/opt/proftpd
说明：
--with-modules=mod_sql:mod_sql_MySQL(和PHP搭配之最佳组合):mod_quotatab:mod_quotatab_sql
这句是让编译ProFTPD 支持MySQL(和PHP搭配之最佳组合)的模块，并有磁盘限额支持；
--with-includes=
这是来指定MySQL(和PHP搭配之最佳组合)服务器includes所在的位置；在这里我设置的是/usr/include/MySQL(和PHP搭配之最佳组合)，因为我的MySQL(和PHP搭配之最佳组合)服务器的includes的确在这个目录；你可以根据自己的机器环境来调整；
--with-libraries= 这是来指定MySQL(和PHP搭配之最佳组合)服务器libraries所在的位置；在这里我设置的是/usr/lib/MySQL(和PHP搭配之最佳组合)，因为我的MySQL(和PHP搭配之最佳组合)服务器的libraries的确在这个目录；你可以根据自己的机器环境来调整；
--prefix=
这是用来指定要把ProFTPD安装在哪个位置，在这里我把ProFTPD安装在了 /opt/proftpd 目录下，您不必自己建目录 /opt/proftpd ，在安装的时候这个目录会自动生成；当然您也可以自己来指定ProFTPD的安装位置；当我们不需要proftpd的时候，就可以直接删除proftpd目录；这样做好象是有点方便；
在configure过程中的错误排查：
如果在configure过程中，也就是上面的./configure 一长串指令执行后，有错误发生，无非是编译工具缺少或者MySQL(和PHP搭配之最佳组合)的includes和libraries的目录指定的不对；自己想想看？
编译和安装：
[root@localhost proftpd-1.3.0rc3]# make [root@localhost proftpd-1.3.0rc3]# make install
如果没有错误发生，这样就安装好了，您可以在 /opt/目录下看到一个/opt/proftpd 的目录；
[root@localhost proftpd-1.3.0rc3]# ls -ld /opt/proftpd/ drwxr-xr-x 8 root root 4096 1月 2 09:37 /opt/proftpd
3、ProFTPD认证中的MySQL(和PHP搭配之最佳组合)数据库
3.1、创建一个ProFTPD的数据库proftpd；
首先您应该会把MySQL(和PHP搭配之最佳组合)数据库服务器打开，以MySQL(和PHP搭配之最佳组合)的超级管理员root进入创建名为proftpd的数据库； [root@localhost ~]# MySQL(和PHP搭配之最佳组合) -uroot -p Enter password: 注：在这里请您输入MySQL(和PHP搭配之最佳组合)的管理密码； Welcome to the MySQL(和PHP搭配之最佳组合) monitor. Commands end with ; or \g. Your MySQL(和PHP搭配之最佳组合) connection id is 41 to server version: 4.1.11 Type 'help;' or '\h' for help. Type '\c' to clear the buffer. MySQL(和PHP搭配之最佳组合)>create database proftpd; MySQL(和PHP搭配之最佳组合)>Grant select,insert,update,delete,create,drop,index,alter,create temporary tables,lock tables on proftpd.* to proftpd@localhost Identified by "123456"; MySQL(和PHP搭配之最佳组合)>quit
说明：
create database proftpd; 这行是创建名为proftpd的数据库； Grant 这行是为proftpd 数据库授权，让用户名为proftpd，密码为123456（这只是一个例子，密码自己定义），这个用来管理proftpd这个数据库； quit 这行是退出MySQL(和PHP搭配之最佳组合)界面；
3.2、导入proftpd数据库；
下面是一个现成的数据库，你只需要导入就行了，比较简单；把下面的代码拷贝下来，然后另存为 proftpd.sql；然后通过下面的命令来导入；
[root@localhost ~]# MySQL(和PHP搭配之最佳组合) -uproftpd -p proftpd -- 数据库: `proftpd` -- -- -------------------------------------------------------- -- -- 表的结构 `ftpgroups` -- CREATE TABLE `ftpgroups` ( `groupname` varchar(30) NOT NULL default '', `gid` int(11) NOT NULL default '1000', `members` varchar(255) NOT NULL default '' ) ENGINE=MyISAM DEFAULT CHARSET=latin1; -- -------------------------------------------------------- -- -- 表的结构 `ftpusers` -- CREATE TABLE `ftpusers` ( `userid` varchar(30) NOT NULL default '', `passwd` varchar(80) NOT NULL default '', `uid` int(10) unsigned NOT NULL default '1000', `gid` int(10) unsigned NOT NULL default '1000', `homedir` varchar(255) NOT NULL default '', `shell` varchar(255) NOT NULL default '/sbin/nologin', `count` int(10) unsigned NOT NULL default '0', `host` varchar(30) NOT NULL default '', `lastlogin` varchar(30) NOT NULL default '', UNIQUE KEY `userid` (`userid`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1; -- -- 导出表中的数据 `ftpusers` -- INSERT INTO `ftpusers` VALUES ('test', 'test', 1000, 1000, '/home/test', '/sbin/nologin',0,'',''); -- -------------------------------------------------------- -- -- 表的结构 `quotalimits` -- CREATE TABLE `quotalimits` ( `name` varchar(30) default NULL, `quota_type` enum('user','group','class','all') NOT NULL default 'user', `per_session` enum('false','true') NOT NULL default 'false', `limit_type` enum('soft','hard') NOT NULL default 'soft', `bytes_in_avail` float NOT NULL default '0', `bytes_out_avail` float NOT NULL default '0', `bytes_xfer_avail` float NOT NULL default '0', `files_in_avail` int(10) unsigned NOT NULL default '0', `files_out_avail` int(10) unsigned NOT NULL default '0', `files_xfer_avail` int(10) unsigned NOT NULL default '0' ) ENGINE=MyISAM DEFAULT CHARSET=latin1; -- -------------------------------------------------------- -- -- 表的结构 `quotatallies` -- CREATE TABLE `quotatallies` ( `name` varchar(30) NOT NULL default '', `quota_type` enum('user','group','class','all') NOT NULL default 'user', `bytes_in_used` float NOT NULL default '0', `bytes_out_used` float NOT NULL default '0', `bytes_xfer_used` float NOT NULL default '0', `files_in_used` int(10) unsigned NOT NULL default '0', `files_out_used` int(10) unsigned NOT NULL default '0', `files_xfer_used` int(10) unsigned NOT NULL default '0' ) ENGINE=MyISAM DEFAULT CHARSET=latin1; 4、ProFTPD的配置文件proftpd.conf 在我们这个例子中，ProFTPD的配置文件在/opt/proftpd/etc目录中，就是proftpd.conf文件；您可以把它改名备份； [root@localhost ~]# cd /opt/proftpd/etc/ [root@localhost etc]# mv proftpd.conf proftpd.confBAK 然后再新建一个 proftpd.conf 文件，内容如下；您可以对这个文件进行相应的调整；其中#号部份就是注掉的，不会生效；注意一下MySQL(和PHP搭配之最佳组合)连接数据库部份；另外如果您不是把ProFTPD安装在了/opt/proftpd目录下，一些东西也是需要调整的；自己看着办吧； # This is a basic ProFTPD configuration file (rename it to # 'proftpd.conf' for actual use. It establishes a single server # and a single anonymous login. It assumes that you have a user/group # "nobody" and "ftp" for normal operation and anon. ServerName "My TestFTP" #这是您的FTP服务器的名字，自己写定 ServerType standalone ServerAdmin xxxxx@xxxxxxxxxxx.com #这是管理员信箱，自己来写； DefaultServer On # Display message DisplayLogin /opt/proftpd/etc/ftplogin.msg #DisplayConnect /net/messages/ftp.pre #DisplayFirstChdir index.txt # Port 21 is the standard FTP port. Port 21 # Limit users to login by username 由于我们在配置文件中，把ftp的用户和用户组的UID和GID都设置为了1000；所以我们得调整一下/etc/passwd 和/etc/group中有关ftp用户和用户组的行；把UID和GID都改为1000； 您可以在/etc/passwd 中找到 ftp用户一行，比如类似下面这行 ftp:x:14:50:FTP User:/var/ftp:/sbin/nologin 在这行中，14是ftp用户的UID,我们要改为1000，50为ftp用户组的GID，也改为1000,其它的可以不变；也就是 ftp:x:1000:1000:FTP User:/var/ftp:/sbin/nologin 接着我们再找到 /etc/group ；在这个文件中找到一行，类似如下的； ftp:x:50: 把这行中的50改为1000；也就是这样的； ftp:x:1000: 6、启动ProFTPD，并测试； [root@localhost ~]# /opt/proftpd/sbin/proftpd [root@localhost ~]# pgrep proftpd 17965 说明：上面就把proftpd 启动起来了；我们通过pgrep 来查看是否有ProFTPD的进程，查看得知已经有了；证明服务器已经启动。我们进入测试阶段； 测试：测试帐号是test，密码是test；您可以用ftp命令来测试，也可以用lftp来测试，也可以用gftp来测试；找一个FTP客户端就行；这个test帐号是怎么来的呢。回头看一下proftpd.sql那段代码中，是否有下面这行； INSERT INTO `ftpusers` VALUES ('test', 'test', 1000, 1000, '/home/test', '/sbin/nologin',0,'',''); 这是我在写文档时，添加的一个测试帐号；只要您把proftpd.sql文件导入了，就有这个帐号；您当然也可以删除它；上面这行说的是在ftpusers的表中，添加一个录；也就是ftp用户的记录；在本文的最下面有说明如何通过MySQL(和PHP搭配之最佳组合)来管理帐号；在这里我们只是测试是不是FTP能用了； 在默认的情况下，test用户的家目录是在/home/test，密码是test；而/home/test是当您第一次以用户test登录时，系统自动建立的；这些都自动的； 如果您用ftp命令连接 [root@localhost home]# ftp localhost Connected to localhost.localdomain. 220 ProFTPD 1.3.0rc3 Server (My TestFTP) [127.0.0.1] 500 AUTH not understood 500 AUTH not understood KERBEROS_V4 rejected as an authentication type Name (localhost:beinan): test 注：用户名 331 Password required for test. 注：密码 Password: 230-You've logged on 5 times, last login at 2006-01-02 12:50:27 230 User test logged in.

注；我们在执行use proftpd;后，我们再查看proftpd中所有的表； +-------------------+ | Tables_in_proftpd | +-------------------+ | ftpgroups | | ftpusers | | quotalimits | | quotatallies | +-------------------+ 4 rows in set (0.00 sec) 我们要查看ftpusers 这个表的结构，我们要用到 DESCRIBE 这个指令，后面接表的名称； MySQL(和PHP搭配之最佳组合)> DESCRIBE ftpusers; +-----------+------------------+------+-----+---------------+-------+ | Field | Type | Null | Key | Default | Extra | +-----------+------------------+------+-----+---------------+-------+ | userid | varchar(30) | | PRI | | | | passwd | varchar(80) | | | | | | uid | int(10) unsigned | | | 1000 | | | gid | int(10) unsigned | | | 1000 | | | homedir | varchar(255) | | | | | | shell | varchar(255) | | | /sbin/nologin | | | count | int(10) unsigned | | | 0 | | | host | varchar(30) | | | | | | lastlogin | varchar(30) | | | | | +-----------+------------------+------+-----+---------------+-------+ 9 rows in set (0.00 sec) 说明： userid 就是FTP的用户名，这个是必填写字段； passwd 是FTP用户的密码，这个是必填写字段； uid和gid字段默认是1000； homedir 是FTP用户的家目录放在哪里，要自己指定； shell 这个是用来指定用户是否能登录系统，这里默认的是不能登录，因为是虚拟用户，所以不能让虚拟用户来登录系统；所以默认是/sbin/nologin； count 是访问次数，默认是0； host 是登录FTP服务器的IP地址记录，可以不设置；服务器会自己纪录； lastlogin 是最后登录时间，这个也是自动生成，可以不必理会； 如何添加用户呢？ 其实添加用户的过程，也就是向proftpd 数据库中的表ftpusers插入纪录的过程；我们上面分析了表的结构；那我们就按其要求来插入用户纪录； 我们看看ftpusers的表中，有哪些纪录； MySQL(和PHP搭配之最佳组合)> select * from ftpusers; +--------+--------+------+------+------------+-----------+-------+-----------+---------------------+ | userid | passwd | uid | gid | homedir | shell | count | host | lastlogin | +--------+--------+------+------+------------+-----------+-------+-----------+---------------------+ | test | test | 1000 | 1000 | /home/test | /bin/bash | 8 | 127.0.0.1 | 2006-01-02 13:03:10 | +--------+--------+------+------+------------+-----------+-------+-----------+---------------------+ 1 row in set (0.01 sec) 尝试插入一条纪录 比如我们想加一个用户，用户名为test2，密码为test2，UID和GID为都为1000,家目录位于/home/test2；值得注意的是UID和GID的只能是1000,因为我们在系统用户设置中做了改动；前面有提到；我们添加所有的FTP用户UID和GID都是 1000； 所以如果您添加用户时，只是改一下userid、passwd和homedir字段处就行了。其它不必改动，当然您非常性MySQL(和PHP搭配之最佳组合)也没有什么不可； INSERT INTO `ftpusers` VALUES ('test2', 'test2', 1000, 1000, '/home/test2', '/sbin/nologin',0,'',''); 查看是否插入成功 MySQL(和PHP搭配之最佳组合)> select * from ftpusers; +--------+--------+------+------+-------------+---------------+-------+-----------+---------------------+ | userid | passwd | uid | gid | homedir | shell | count | host | lastlogin | +--------+--------+------+------+-------------+---------------+-------+-----------+---------------------+ | test | test | 1000 | 1000 | /home/test | /bin/bash | 8 | 127.0.0.1 | 2006-01-02 13:03:10 | | test2 | test2 | 1000 | 1000 | /home/test2 | /sbin/nologin | 0 | | | +--------+--------+------+------+-------------+---------------+-------+-----------+---------------------+ 2 rows in set (0.00 sec) 再举一例；添加一个用户名为test3，密码为test3 ，并且把test3的家目录放在/opt/test3中； MySQL(和PHP搭配之最佳组合)> INSERT INTO `ftpusers` VALUES ('test3', 'test3', 1000, 1000, '/opt/test3', '/sbin/nologin',0,'',''); 添加好后，测试一下用户test3是否能登录，并且上传文件；下面的例子证明是成功的； [root@localhost ~]# lftp test3:test3@localhost lftp test3@localhost:~> ls lftp test3@localhost:/> put /home/beinan/fcitx-3.2-051108.tar.bz2 4164490 bytes transferred lftp test3@localhost:/> ls -rw-r--r-- 1 test3 ftp 4164490 Jan 2 06:08 fcitx-3.2-051108.tar.bz2 lftp test3@localhost:/> 如果你想删除一个用户，您可以用 MySQL(和PHP搭配之最佳组合)的delete 指令；比如我想删除test2这个用户；可以用..... MySQL(和PHP搭配之最佳组合)> DELETE FROM ftpusers WHERE userid="test2"; 如果想更新一条用户纪录，比如test用户密码字段； MySQL(和PHP搭配之最佳组合)> update ftpusers set passwd="aaasss" where userid="test"; 也就是说，你想更新用户纪录的那个字段就更新什么，下面公式； MySQL(和PHP搭配之最佳组合)>update 数据表 set 字段="赋值" where 关健字段="字段值"; 在这里关健字段是唯一的，这样才能找到你所要更新的纪录，表达不太好；如果不太熟悉，慢慢理解吧；我也不会MySQL(和PHP搭配之最佳组合)；呵，难为人师...... 在这里，我们还是把userid 做为关健字段，因为只有这个字段才是唯一的； 再比如，我们想更新用户的家目录，比如我想把test用户的家目录改到 /opt/test； MySQL(和PHP搭配之最佳组合)> select userid,homedir from ftpusers where userid="test"; +--------+-----------+ | userid | homedir | +--------+-----------+ | test | /home/test | +--------+-----------+ 通过上面的，我们得知test目前的家目录在/home/test，下面我们来更改到/opt/test； MySQL(和PHP搭配之最佳组合)> update ftpusers set homedir="/opt/test" where userid="test"; Query OK, 1 row affected (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 0 MySQL(和PHP搭配之最佳组合)> select userid,homedir from ftpusers where userid="test"; +--------+-----------+ | userid | homedir | +--------+-----------+ | test | /opt/test | +--------+-----------+ 7.3 ProFTPD 用户磁盘限额管理； 我们在前面所导入的proftpd 数据库中，有这样一段； CREATE TABLE `quotalimits` ( `name` varchar(30) default NULL, `quota_type` enum('user','group','class','all') NOT NULL default 'user', `per_session` enum('false','true') NOT NULL default 'false', `limit_type` enum('soft','hard') NOT NULL default 'soft', `bytes_in_avail` float NOT NULL default '0', `bytes_out_avail` float NOT NULL default '0', `bytes_xfer_avail` float NOT NULL default '0', `files_in_avail` int(10) unsigned NOT NULL default '0', `files_out_avail` int(10) unsigned NOT NULL default '0', `files_xfer_avail` int(10) unsigned NOT NULL default '0' ) ENGINE=MyISAM DEFAULT CHARSET=latin1; 说明： 上面其实就是在proftpd库中创建一个表quotalimits；我们在proftpd的数据库中，再来查看一下quotalimits表的结构，这样方便我们理解和使用磁盘限额； MySQL(和PHP搭配之最佳组合)> DESCRIBE quotalimits; +------------------+------------------------------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +------------------+------------------------------------+------+-----+---------+-------+ | name | varchar(30) | YES | | NULL | | | quota_type | enum('user','group','class','all') | | | user | | | per_session | enum('false','true') | | | false | | | limit_type | enum('soft','hard') | | | soft | | | bytes_in_avail | float | | | 0 | | | bytes_out_avail | float | | | 0 | | | bytes_xfer_avail | float | | | 0 | | | files_in_avail | int(10) unsigned | | | 0 | | | files_out_avail | int(10) unsigned | | | 0 | | | files_xfer_avail | int(10) unsigned | | | 0 | | +------------------+------------------------------------+------+-----+---------+-------+ 说明； quotalimits name - username quota_type - user, group, class, all (we use user) per_session - true or false (we use false) limit_type - quota limit type - hard or soft (we use soft) bytes_in_avail - upload limit in bytes - allowed bytes on disk (eg diskquota) bytes_out_avail - download limit in bytes - allowed bytes a user can download bytes_xfer_avail - allowed bytes a user can transfer in/out files_in_avail - upload limit in files - allowed number of uploaded files files_out_avail - allowed number of downloaded files files_xfer_avail - allowed number of files a user can transfer in/out name 应该这样理解，既能表示单个用户，也能表示用户组名；如果我们在quota_type（限额类型）中使用group来认证的话，那就得在这里设置组名，这样整组都具有统一的磁盘限额的特性；当然您要在ftpgroups表中插入组纪录；并且在member字段中得把用户一个一个的列进去，这是后话了；先自己研究一下，只是插入纪录的事；我们只说最简单的单个用户的磁盘限额；默认值可以为空NULL，如果为空则针对所在有quota_type中设置的类型，比如在quota_type中设置为user ，就是针对所有ftpusers 中的用户起作用；如果是group名，也是对ftpgroups 所有组作用； quota_type 磁盘限额类型，可以设置为用户，也可以设置为用户组group ；如果您的name写的是用户组，那在这里就得设置为group来认定；默认为user认证； per_session 默认为false； limit_type 默认为soft； bytes_in_avail 用户占用空间大小，也就是家目录的空间最大可以让用户占用多少，单位是byte；默认为0，0是不受限制，以下同理； bytes_out_avail 注；所有下载文件的总和，默认为0； bytes_xfer_avail 注；一个用户上传下载流量总和，默认为0 files_in_avail 注：限制上传文件总数，默认为0； files_out_avail 注；限制下载文件个数总计，默认为0 files_xfer_avail 注：允许下载和上传的文件总和我，默认为0； 由此看来，我们比如想让test用户，约束空间大小为100M，其它不受限制；则可用下面的MySQL(和PHP搭配之最佳组合)命令添加； 先让我们对照quotalimits表的结构，然后根据表的结构来添加； MySQL(和PHP搭配之最佳组合)> describe quotalimits;

Please see our earlier Howto guide: Installation The easiest is to install proftpd from the Mandrake rpms and overwrite /usr/sbin/proftpd with a symlink to the one you create here in /usr/local/sbin. You can't use the rpm version of proftpd as it doesn't have MySQL(和PHP搭配之最佳组合) support built in. Log in as your user account to do the installation. Instructions in bold should be done as root. You should be able to copy and paste the text in the yellow boxes straight into your Mandrake PC. We have tested this on a clean server and it all seems to work fine. If you have any problems use the Discussion Forum on this site to let us know. You can always let us know if this is useful anyway! Get the sources # as user cd mkdir src cd src # Proftpd source - note that this contains mod_sql and mod_quotatab wget ftp://ftp.proftpd.org/distrib/source/proftpd-1.2.10.tar.gz Note: make sure that your path to the installation directory does not contain spaces in any of the directory names as this confuses the ./configure script totally! Unpack sources # as user cd mkdir proftpd cd proftpd # Unpack sources tar -xzf ../src/proftpd-1.2.10.tar.gz Compile and install This assumes that the MySQL(和PHP搭配之最佳组合) libraries and headers are placed where Mandrake puts them (i.e. /usr/lib and /usr/include/MySQL(和PHP搭配之最佳组合) respectively). If you have used a different MySQL(和PHP搭配之最佳组合) installation you just need to check that you get the path to these MySQL(和PHP搭配之最佳组合) files correct. cd proftpd-1.2.10 ./configure --with-modules=mod_sql:mod_sql_MySQL(和PHP搭配之最佳组合):mod_quotatab:mod_quotatab_sql \ --with-includes=/usr/include/MySQL(和PHP搭配之最佳组合) \ --with-libraries=/usr/lib make su make install # make a symbolic link to the installed binary in /usr/sbin - overwriting the one from the rpm if installed # so that the startup script works OK mv /usr/sbin/proftpd /usr/sbin/proftpd.rpmsave ln -s /usr/local/sbin/proftpd /usr/sbin/proftpd Unix Configuration As far as UNIX is concerned we use one real group account ftpgroup (id 5500) as every user will be jailed to their home directory using the 'DefaultRoot ~/' directive. We set up one main ftpuser account (id: 5500) with this group and a guest account ftpguest (id 5501). groupadd -g 5500 ftpgroup adduser -u 5500 -s /bin/false -d /bin/null -c "proftpd user" -g ftpgroup ftpuser Note: I also add a guest user so that your client sites can have a place for their guest users to transfer files. Just run: adduser -u 5501 -s /bin/false -d /bin/null -c "proftpd guest" -g ftpgroup ftpguest add a password and then remember to add them to your database as members of the ftpgroup by adding a new record there. To add a guest user, add a record for a user with userid of 5501 and set the permissions on the folders you want to share like this: chmod 755 From_folder chmod 731 To_folder leaving the user and group as ftpuser.ftpgroup Their clients will now only be able to download from the From_folder and drop files, but not list files in the To_folder. MySQL(和PHP搭配之最佳组合) Configuration Create the database tables in MySQL(和PHP搭配之最佳组合) for authentication and logging. We use a database called ftpdb which we access using a MySQL(和PHP搭配之最佳组合) user proftpd with password 'password'. (Clearly substitute your own password in here). You need to log into MySQL(和PHP搭配之最佳组合) using your root account and password. MySQL(和PHP搭配之最佳组合) -u root -p create database ftpdb; grant select, insert, update on ftpdb.* to proftpd@localhost identified by 'password'; use ftpdb; # # Table structure for table `ftpgroup` # CREATE TABLE ftpgroup ( groupname varchar(16) NOT NULL default '', gid smallint(6) NOT NULL default '5500', members varchar(16) NOT NULL default '', KEY groupname (groupname) ) TYPE=MyISAM COMMENT='ProFTP group table'; # # Dumping data for table `ftpgroup` # INSERT INTO `ftpgroup` VALUES ('ftpgroup', 5500, 'ftpuser'); INSERT INTO `ftpgroup` VALUES ('ftpgroup', 5500, 'ftpguest'); # -------------------------------------------------------- # # Table structure for table `ftpquotalimits` # CREATE TABLE ftpquotalimits ( name varchar(30) default NULL, quota_type enum('user','group','class','all') NOT NULL default 'user', per_session enum('false','true') NOT NULL default 'false', limit_type enum('soft','hard') NOT NULL default 'soft', bytes_in_avail int(10) unsigned NOT NULL default '0', bytes_out_avail int(10) unsigned NOT NULL default '0', bytes_xfer_avail int(10) unsigned NOT NULL default '0', files_in_avail int(10) unsigned NOT NULL default '0', files_out_avail int(10) unsigned NOT NULL default '0', files_xfer_avail int(10) unsigned NOT NULL default '0' ) TYPE=MyISAM; # -------------------------------------------------------- # # Table structure for table `ftpquotatallies` # CREATE TABLE ftpquotatallies ( name varchar(30) NOT NULL default '', quota_type enum('user','group','class','all') NOT NULL default 'user', bytes_in_used int(10) unsigned NOT NULL default '0', bytes_out_used int(10) unsigned NOT NULL default '0', bytes_xfer_used int(10) unsigned NOT NULL default '0', files_in_used int(10) unsigned NOT NULL default '0', files_out_used int(10) unsigned NOT NULL default '0', files_xfer_used int(10) unsigned NOT NULL default '0' ) TYPE=MyISAM; # # Table structure for table `ftpquotatallies` # CREATE TABLE `ftpquotatallies` ( `name` varchar(30) NOT NULL default '', `quota_type` enum('user','group','class','all') NOT NULL default 'user', `bytes_in_used` float NOT NULL default '0', `bytes_out_used` float NOT NULL default '0', `bytes_xfer_used` float NOT NULL default '0', `files_in_used` int(10) unsigned NOT NULL default '0', `files_out_used` int(10) unsigned NOT NULL default '0', `files_xfer_used` int(10) unsigned NOT NULL default '0' ) TYPE=MyISAM; # -------------------------------------------------------- # # Table structure for table `ftpuser` # CREATE TABLE ftpuser ( id int(10) unsigned NOT NULL auto_increment, userid varchar(32) NOT NULL default '', passwd varchar(32) NOT NULL default '', uid smallint(6) NOT NULL default '5500', gid smallint(6) NOT NULL default '5500', homedir varchar(255) NOT NULL default '', shell varchar(16) NOT NULL default '/sbin/nologin', count int(11) NOT NULL default '0', accessed datetime NOT NULL default '0000-00-00 00:00:00', modified datetime NOT NULL default '0000-00-00 00:00:00', Prima(最完善的虚拟主机管理系统)RY KEY (id), UNIQUE KEY userid (userid) ) TYPE=MyISAM COMMENT='ProFTP user table'; INSERT INTO `ftpuser` VALUES (1, 'testaccount', 'ftppasswd', 5500, 5500, '/home/testdomain.com', '/sbin/nologin',0,'',''); exit; Notes: * The group table lists the members of each group. This does not need any records for a simple setup. * The user table lists each of your ftp users and records their stats and is used for authentication and pointing proftpd to the correct home directory. Using the directive 'asdfasf' we make proftpd create the home directory if one does not already exist. * The quotalimits table is used to se the current quota for the user matching its entry. * The quotatallies table is used by proftpd to keep track of the user's quotas and will be filled if there is a matching userfield 'name' when a user logs in. * We have added a user test account just called "testaccount" to check things are working ok. Field Explanations: quotalimits name - username quota_type - user, group, class, all (we use user) per_session - true or false (we use true) limit_type - quota limit type - hard or soft (we use hard) bytes_in_avail - upload limit in bytes - allowed bytes on disk (eg diskquota) bytes_out_avail - download limit in bytes - allowed bytes a user can download bytes_xfer_avail - allowed bytes a user can transfer in/out files_in_avail - upload limit in files - allowed number of uploaded files files_out_avail - allowed number of downloaded files files_xfer_avail - allowed number of files a user can transfer in/out quotatallies name quota_type bytes_in_used - upload tally in bytes bytes_out_used - download tally in bytes bytes_xfer_used - transfer tally in bytes files_in_used - upload tally in files files_out_used - download tally in files files_xfer_used - transfer tally in files If a value of any limit field is set to '0' it is unlimited. You can read the documentation that comes with mod_quotatab for MySQL(和PHP搭配之最佳组合) here. Author's Note: You can test a 15MB quota limit on 'testaccount' by inserting this record into 'quotalimits': INSERT INTO quotalimits VALUES('testaccount','user','true','hard','15728640','0','0','0','0','0'); I think you have to log in with this record in place before it works. It also will allow you to upload, but then deletes the file if you are over the limit. This is a bit irritating because on normal user disk quotas, you get a message as you try to upload, not after. So you might get some unhappy users who don't know why they can't upload. Also the message that you have exceeded the limit appears in the ftp client transcript and your users will miss this if they don't show transcripts. On a related note, I can seem to get any joy out of the quotatallies stuff. When I get more time, I may investigate this. In the meantime, if any of you find out what is going on there, it would be cool if you leave a note in the forum here - then everyone can benefit. Proftpd Config File Here is our complete configuration file setup with MySQL(和PHP搭配之最佳组合) and quota support.

We use the proftpd startup script provided by the rpm distribution. You can download it here. Testing Start the service using /etc/rc.d/init.d/proftpd and login to the ftp server using 'testaccount' and 'ftppasswd'. If the home directory '/home/testdomain.com' does not already exist it will be created. Have fun!! A few useful tips If you want to check that queries are coming through to MySQL(和PHP搭配之最佳组合), turn on logging by adding a line to your MySQL(和PHP搭配之最佳组合) configuration file such as: log=/var/lib/MySQL(和PHP搭配之最佳组合)/MySQL(和PHP搭配之最佳组合).log Remember to turn off logging when you are done as it will slow things down with it on! (Note that the MySQL(和PHP搭配之最佳组合) config file is usually '/etc/my.cnf'. If you don't have one MySQL(和PHP搭配之最佳组合) usually provides a set which you can copy according to the size of server you want to run. For example, a huge server can use : '/usr/share/MySQL(和PHP搭配之最佳组合)/my-huge.cnf')
