安装环境：redhat8，安装选择的是自定义，没选数据库和ftp部分（因为我们要自己编译，如果安装了也没问题，你可以rpm -qa|grep mysql ,然后rpm -e mysql*.rpm卸载掉
网上关于proftpd的安装文章实在是不少，我只是稍微整理了一下，并且使用了新的 quota磁盘限额模块,mysql选择3.23.56版。
首先下载源码
proftpd1.2.8:
ftp://ftp.proftpd.org/上下载吧
ftp://ftp.proftpd.org/distrib/source/proftpd-1.2.8.tar.gz
mod_quotatab-1.2.7
http://www.castaglia.org/proftpd/modules/proftpd-mod-quotatab-1.2.7.tar.gz（对应proftpd1.2.8版本的）
mysql3.23.56:
http://www.mysql.com/downloads/mysql-3.23.html#Source
注意是下载源代码包（我一般喜欢自己编译）
全部下载到/root目录。
1，安装mysql3.23.56
#groupadd mysql
#useradd -g mysql mysql
#cd /root
#tar -zxvf mysql-3.23.56.tar.gz
#cd mysql-3.23.56
#./configure --prefix=/usr/local/mysql
#make
#make install
#scripts/mysql_install_db
#chown -R root /usr/local/mysql
#chown -R mysql /usr/local/mysql/var
#chgrp -R mysql /usr/local/mysql
#cp support-files/my-medium.cnf /etc/my.cnf
#/usr/local/mysql/bin/safe_mysqld --user=mysql &
2，安装proftpd
将proftpd的源码包解压缩到某临时目录下：
localhost# tar -zxvf proftpd-1.2.8.tar.gz
解压缩 mod_quotatab-1.2.7
localhost# tar -zxvf proftpd-mod-quotatab-1.2.7.tar.gz
进入 mod_quotatab 目录
localhost proftpd# cd mod_quotatab
把mod_quotatab中的文件拷贝到 proftpd 中的modules 目录中
localhost mod_quotatab# cp * ../proftpd-1.2.8/modules
在开始运行configure之前，我们要先改动一个文件
进入 proftpd-1.2.8/contrib 目录
localhost mod_quotatab # cd ../proftpd-1.2.8/contrib
修改 mod_sql_mysql.c
localhost contrib# vi mod_sql_mysql.c
找到#include 把他该为你实际路径
如果你的mysql 安装在/usr/local/mysql 下，就像我前面一样，就把它修改为#include
然后
localhost contrib# cd ..
localhostproftpd-1.2.7#./configure --prefix=DIR --with-modules=mod_sql:mod_sql_mysql:mod_quotatab:mod_quotatab_sql --with-includes=DIR --with-libraries=DIR
需要修改的三个地方
--prefix=DIR 你要安装到哪里
--with-includes=DIR mysql 的includes 目录
--with-libraries=DIR mysql 的lib 目录
然后
make
make install 完成安装
3.配置proftpd.conf
接下来，进入你安装好的proftpd目录 ，修改etc/proftpd.conf 文件开始配置
基本配置讲解：
示例：proftpd.conf
ServerName "HRBEU's ftp server" #服务名
ServerType standalone #f服务器启动方式
DefaultServer on
# Port 21 is the standard FTP port.
Port 21 ＃使用端口
# Umask 022 is a good standard umask to prevent new dirs and files
# from being group and world writable.
Umask 022
#limit the user in his owner directory
DefaultRoot ~ ＃限制用户只能在自己的目录里，不能上去进入其他目录
#put the proftpd log files in /var/log/ftp.syslog
SystemLog /data/logs/ftp.syslog ＃proftpd的系统日志存放地
#TransferLog log files
TransferLog /data/logs/ftp.transferlog ＃传输日志存放地
#set The maxtimes user Attempts times
MaxLoginAttempts 30 ＃当登陆失败后，可以尝试登陆的次数
#setup the Restart
AllowRetrieveRestart on
#setup the download and upload speed
#TransferRate [kilobytes-per-sec[:100]] ＃1.2.8版本的速率限制
#setup the disk quota
QuotaDirectoryTally on
#quota b"|"Kb"|"Mb"|"Gb"
#setup the disk quota
#QuotaDirectoryTally on
#quota b"|"Kb"|"Mb"|"Gb"
QuotaDisplayUnits Kb
QuotaEngine on
QuotaLog /data/logs/Quota.log
QuotaShowQuotas on
# We put our mod_sql directives in a block so they'll be
# inherited by the block below, and any other
# blocks we may want to add. For a simple server these don't need to
# be in a block but it won't hurt anything.
# Specify our connection information. Both mod_sql_mysql and
# mod_sql_postgres use the same format, other backends may specify a
# different format for the first argument to SQLConnectInfo. By not
# specifying a fourth argument, we're defaulting to 'PERSESSION'
# connections -- a connection is made to the database at the start of
# the session and closed at the end. This should be fine for most
# situations.
# SQLConnectInfo dbname@host:port username password
SQLConnectInfo ftp@localhost:3306 wgh 58648217
# Specify our authentication schemes. Assuming we're using
# mod_sql_mysql, here we're saying 'first try to authenticate using
# mysql's password scheme, then try to authenticate the user's
# password as plaintext'. Note that 'Plaintext' isn't a smart way to
# store passwords unless you've got your database well secured.
SQLAuthTypes Backend Plaintext
# Specify the table and fields for user information. If you've
# created the database as it specifies in 'README.mod_sql', you don't
# need to have this directive at all UNLESS you've elected not to
# create some fields. In this case we're telling mod_sql to look in
# table 'users' for the fields 'username','password','uid', and
# 'gid'. The 'homedir' and 'shell' fields are specified as 'NULL' --
# this will be explained below.
# SQLUserInfo users username password uid gid NULL NULL
SQLUserInfo FTPUSERS userid passwd uid gid home shell
SQLGroupInfo FTPGRPS groupname gid members
# Here we tell mod_sql that every user it authenticates should have
# the same home directory. A much more common option would be to
# specify a homedir in the database and leave this directive out. Note
# that this directive is necessary in this case because we specified
# the homedir field as 'NULL', above. mod_sql needs to get homedir
# information from *somewhere*, otherwise it will not allow access.
# SQLDefaultHomedir "/tmp"
# This is not a mod_sql specific directive, but it's here because of
# the way we specified 'SQLUserInfo', above. By setting this to
# 'off', we're telling ProFTPD to allow users to connect even if we
# have no (or bad) shell information for them. Since we specified the
# shell field as 'NULL', above, we need to tell ProFTPD to allow the
# users in even though their shell doesn't exist.
RequireValidShell off
# Here we tell mod_sql how to get out group information. By leaving
# this commented out, we're telling mod_sql to go ahead and use the
# defaults for the tablename and all the field names.
# SQLGroupInfo groups groupname gid members
# For small sites, the following directive will speed up queries at
# the cost of some memory. Larger sites should read the complete
# description of the 'SQLAuthenticate' directive; there are options
# here that control the use of potentially expensive database
# queries. NOTE: these arguments to 'SQLAuthoritative' limit the way
# you can structure your group table. Check the README for more
# information.
SQLAuthenticate users
# Finally, some example logging directives. If you have an integer
# field named 'count' in your users table, these directives will
# automatically update the field each time a user logs in and display
# their current login count to them.
# SQLNamedQuery getcount SELECT "count, userid from users where userid='%u'"
# SQLNamedQuery updatecount UPDATE "count=count+1 WHERE userid='%u'" users
# SQLShowInfo PASS "230" "You've logged on %{getcount} times, %u"
# SQLLog PASS updatecount
SQLHomedirOnDemand on
#...SQL...............
SQLNamedQuery get-quota-limit SELECT "name, quota_type, per_session, limit_type, bytes_in_avail, bytes_out_avail, bytes_xfer_avail, files_in_avail, files_out_avail, files_xfer_avail FROM quotalimits 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 WHERE name = '%{0}' AND quota_type = '%{1}'"

SQLNamedQuery insert-quota-tally INSERT "%{0}, %{1}, %{2}, %{3}, %{4}, %{5}, %{6}, %{7}" quotatallies

# close our block.

# to 30. If you need to allow more than 30 concurrent connections
# at once, simply increase this value. Note that this ONLY works
# in standalone mode, in inetd mode you should use an inetd server
# that allows you to limit maximum number of processes per service
# (such as xinetd)
MaxInstances 30
# Set the normal user and group permissions for the server.
User FTPUSR
Group FTPGRP
# Normally, we want files to be overwriteable.
AllowOverwrite on
# A basic anonymous configuration, no upload directories. If you
# don't want to support anonymous access, simply remove this
# ... block.

Group ftp
# We want clients to be able to login with "anonymous" as well as "ftp"
UserAlias anonymous ftp
# Limit the maximum number of anonymous logins

# We want 'welcome.msg' displayed at login, and '.message' displayed
# in each newly chdired directory.
DisplayLogin welcome.msg
DisplayFirstChdir .message
# Limit WRITE everywhere in the anonymous chroot
DenyAll
4,mysql 用户认证部分
在proftpd.conf中加入以下内容
#设置MySQL认证：
#数据库联接的信息，DatabaseName是数据库名， HostName是主机名，
#Port是端口号，UserName是连接数据库的用户名，Password是密码。
SQLConnectInfo ftp@localhost:3306 ftpuser ftppasswd
#数据库认证的类型：
SQLAuthTypes Backend Plaintext
#指定用来做用户认证的表的有关信息。("FTPUSERS"和"FTPGRPS"是数据表名字，等一会而在下面建立)
SQLUserInfo FTPUSERS userid passwd uid gid homedir shell
SQLGroupInfo FTPGRPS groupname gid members
#设置如果shell为空时允许用户登录：
RequireValidShell off
#数据库的鉴别
SQLAuthenticate users groups usersetfast groupsetfast
#如果home目录不存在，则系统会为根据它的home项新建一个目录：
SQLHomedirOnDemand on
然后在这个数据库中建立一个用户表FTPUSERS，这个表是必须的：
use ftp;
create table FTPUSERS (
userid TEXT NOT NULL,
passwd TEXT NOT NULL,
uid INT NOT NULL,
gid INT NOT NULL,
home TEXT,
shell TEXT
);
此表格是为了用户认证所需要的，其中userid、passwd是必不可少的，userid是用做FTP服务的用户名；passwd是指此用户的密码；uid是系统用户的ID，也就是所映射的系统用户；gid是所属系统组的ID；home是该用户所在的HOME目录；shell可以为该用户指定相应的shell。当然你可以建立更多的字段，例如：用来记录用户登录次数的count，或者是日期的date，如果你对配置熟悉了之后，你可以根据自己的喜欢添加更多的功能。在此就不多讲。
3、如果你想需要所有的功能，你还可以添加另外一个需要的表：FTPGRPS，也就是确定组的表格，当然也可以不用，这里讲一个它的格式：
create table FTPGRPS (
grpname TEXT NOT NULL,
gid SMALLINT NOT NULL,
members TEXT NOT NULL,
);
其中grpname是组的名称，gid是系统组的ID，members是组的成员。注意：多成员，他们之间要用逗号隔开，不能使用空格。
4、为空表格插入记录：
INSERT INTO FTPUSERS (userid, passwd, uid, gid, home, shell)
valueS ('user1', '999999', '1000', '1000', '/home/FTP/user1', '' );
按此格式你可以插入这每一个用户添加一个记录。
如果你要想应用到更多的功能，且建立了组的表格，你也要为此添加记录，不过一定要注意在members的字段多个成员一定要用逗号隔开。
INSERT INTO FTPGRPS VALUES ('FTPGRPS', 1000, 'FTPUSR');
四、为FTP用户建立相应的系统用户。
在本例中，只整个FTP服务只提供一个有效的系统用户FTPUSR和组FTPGRP，当然你也可以设置多个系统用户。但出于安全的考虑，我只设一个，用他来启动FTP daemon，并把所有的FTP用户映射过这个用户。
先建立FTPGRP组：
groupadd -g 1000 -r FTPGRP
建立FTPUSR用户：
adduser -u 1000 -g 1000 -d /home/FTP -s /bin/bash -r FTPUSR
为FTPUSR建立HOME，把所有的FTP user 活动空间全放在此目录下：
mkdir /home/FTP
chown FTPUSR /home/FTP
chgrp FTPGRP /home/FTP
到这里MYSQL认证部分就算基本配置好了，接下来是磁盘限额部分
首先，还是编辑proftpd文件
#磁盘限额部分
QuotaDirectoryTally on
#磁盘限额单位 b"|"Kb"|"Mb"|"Gb"
QuotaDisplayUnits "Kb"
QuotaEngine on
#磁盘限额日志记录
QuotaLog "你的LOG路径"
# 打开磁盘限额信息，当登陆FTP帐户后，使用命令 "quote SITE QUOTA" 后可显示当前用户的磁盘限额
QuotaShowQuotas on
#以下是SQL调用语句，不用修改直接拷贝过去
SQLNamedQuery get-quota-limit SELECT "name, quota_type, per_session, limit_type, bytes_in_avail, \
bytes_out_avail, bytes_xfer_avail, files_in_avail, files_out_avail, files_xfer_avail FROM quotalimits \
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 \
WHERE name = '%{0}' AND quota_type = '%{1}'"
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
QuotaTallyTable sql:/get-quota-tally/update-quota-tally/insert-quota-tally
然后建立mysql 数据表
CREATE TABLE quotalimits (
name VARCHAR(30),
quota_type ENUM("user", "group", "class", "all") NOT NULL,
per_session ENUM("false", "true") NOT NULL,
limit_type ENUM("soft", "hard") NOT NULL,
bytes_in_avail FLOAT NOT NULL,
bytes_out_avail FLOAT NOT NULL,
bytes_xfer_avail FLOAT NOT NULL,
files_in_avail INT UNSIGNED NOT NULL,
files_out_avail INT UNSIGNED NOT NULL,
files_xfer_avail INT UNSIGNED NOT NULL
);
CREATE TABLE quotatallies (
name VARCHAR(30) NOT NULL,
quota_type ENUM("user", "group", "class", "all") NOT NULL,
bytes_in_used FLOAT NOT NULL,
bytes_out_used FLOAT NOT NULL,
bytes_xfer_used FLOAT NOT NULL,
files_in_used INT UNSIGNED NOT NULL,
files_out_used INT UNSIGNED NOT NULL,
files_xfer_used INT UNSIGNED NOT NULL
);
quotatallies表不需要作修改，它记录了用户当前的磁盘使用情况，由程序自动记录
quotalimits 表中一些字段的含意
quota_type 磁盘限额的鉴别
bytes_in_avail 上传最大字节数，就是FTP用户空间容量
bytes_out_avail 下载最大字节数
bytes_xfer_avail 总共可传输的文件的最大字节数(上传和下载流量)
files_in_avail 总共能上传文件的数目
files_out_avail 能从服务器上下载文件的总数目
files_xfer_avail 总共可传输文件的数目(上传和下载)
开始使用磁盘限额，我们要将上面建立的user1帐号给予10M空间，最多能上传500个文件到服务器上，文件传输流量为20M，只能传输10个文件。只要在MYSQL中插入
INSERT INTO `quotalimits` ( `name` , `quota_type` , `per_session` , `limit_type` , `bytes_in_avail` , `bytes_out_avail` , `bytes_xfer_avail` , `files_in_avail` , `files_out_avail` , `files_xfer_avail` )
VALUES ('user1', 'user', 'false', 'soft', '10240000', '0', '2048000', '500', '0', '10');
就可以了，不需要设置的部分用0代替就可以了
现在运行proftpd，登陆到user1 ，使用quote SITE QUOTA 就会显示user1用户的磁盘使用情况
ftp> quote SITE QUOTA
200-The current quota for this session are [current/limit]:

OK,安装完毕

至于你现在想写什么样的php程序来控制数据库，然后让一切web化，就不在本文讨论范围了。其实大家只要稍微修改一下，就可以作为虚拟主机提供给大家。因为你可以修改数据表！
