以前使用的proftpd，但是没有和mysql结合起来。导致用户管理上不方便。
这2天研究了一下proftpd的配置，做到了使ProFTPD 支持MySQL数据库，添加虚拟用户认证及Quotas(磁盘限额)。具体的如下：
1、安装proftpd带mysql支持
apt-get install proftpd-mysql
2、创建proftpd使用的mysql数据库
[root@localhost ~]# mysql -uroot -p
mysql>create database proftpd;
mysql>Grant select,insert,update,delete,create,drop,index,alter,create temporary tables,lock tables on proftpd.* to proftpd@localhost Identified by "password";
mysql>quit
3、导入数据库。这一步，可以使用phpmyaqmin进行
-- 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=utf8;
-- --------------------------------------------------------
--
-- 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=utf8;
--
-- 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=utf8;
-- --------------------------------------------------------
--
-- 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=utf8;
4、修改proftpd的配置文件nano proftpd.conf
在其中增加下面几行（注意，下面的部分仅仅是mysql连接部分，关于proftpd的配置文件写法，参照我以前的文章把）
5、启动prfoftpd，测试#——– load sql.mod for mysql authoritative ——–#
SQLConnectInfo proftpd@localhost proftpd proftpd
#注：上面这行是MySQL连接服务器部份，自己根据情况来改一改；
SQLAuthTypes Plaintext

SQLAuthenticate users groups

SQLNamedQuery getlastlogin SELECT "lastlogin from ftpusers where userid=’%u’"
SQLNamedQuery updatelogininfo UPDATE "count=count+1,host=’%h’,lastlogin=current_timestamp() WHERE userid=’%u’" ftpusers
SQLShowInfo PASS "230" "You’ve logged on %{getcount} times, last login at %{getlastlogin}"

WHERE name = ‘%{0}’ AND quota_type = ‘%{1}’"
SQLNamedQuery get-quota-tally SELECT "name, quota_type, bytes_in_used, bytes_out_used,
bytes_xfer_used, files_in_used, files_out_used, files_xfer_used FROM quotatallies

SQLNamedQuery update-quota-tally UPDATE "bytes_in_used = bytes_in_used + %{0},
bytes_out_used = bytes_out_used + %{1}, bytes_xfer_used = bytes_xfer_used + %{2},
files_in_used = files_in_used + %{3}, files_out_used = files_out_used + %{4},
files_xfer_used = files_xfer_used + %{5}
WHERE name = ‘%{6}’ AND quota_type = ‘%{7}’" quotatallies
SQLNamedQuery insert-quota-tally INSERT "%{0}, %{1}, %{2}, %{3}, %{4}, %{5}, %{6}, %{7}" quotatallies
QuotaLimitTable sql:/get-quota-limit

需要注意的事情有：
注意检查添加的虚拟用户的主目录和shell设置是否正常，这2个是不能登陆的最常见的原因
另外，似乎proftpd启用了虚拟用户之后，和vsftpd一样，正常用户无法登陆。而且，虚拟用户的用户名，不能和系统用户的用户名相同，否则，不能正常登陆
