[zt]proftpd+mysql用户认证+quota磁盘限额

shihao

将proftpd的源码包解压缩到某临时目录下：
# bunzip2 proftpd-1.2.7.tar.bz2
# tar -xvf proftpd-1.2.7.tar
# gunzip proftpd-mod-quotatab-1.2.4.tar.gz
# tar -xvf proftpd-mod-quotatab-1.2.4.tar
# cd mod_quotatab
# cp * ../proftpd-1.2.7/modules //把这个目录中的文件拷proftpd中的modules 目录中
# cd ../proftpd-1.2.7/contrib
#vi mod_sql_mysql.c
修改#include <mysql/mysql.h>根据你的mysql 安装在哪里来决定：
#include </usr/local/mysql/include/mysql/mysql.h>
# cd ~/porftpd-1.2.7]
#./configure --prefix=/usr/local/proftpd \
--with-modules=mod_sql:mod_sql_mysql:mod_quotatab:mod_quotatab_sql \
--with-includes=/usr/local/mysql/include/mysql \ // mysql 的includes 目录
--with-libraries=/usr/local/mysql/lib/mysql // mysql 的lib 目录
# make
# make install
将/etc/passwd 和group 拷贝到/usr/local/proftpd/etc下
并修成如下样子：
proftpd/etc/passwd
root:x:0:1:Super-User:/:/sbin/sh
daemon:x:1:1::/:
uucp:x:5:5:uucp Admin:/usr/lib/uucp:
FTPUSR:x:1000:1000::/ftp:/bin/sh

proftpd/etc/group
root::0:root
other::1:
uucp::5:root,uucp
FTPGRP::1000:

修改proftpd/etc/proftpd.conf 文件配置 (我的配置文件，这是基本的功能)
# 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 "WELCOME TO JLNU.EDU.CN "
ServerType standalone
DefaultServer on

# Port 21 is the standard FTP port.
Port 21

# Umask 022 is a good standard umask to prevent new dirs and files
# from being group and world writable.
Umask 022

# To prevent DoS attacks, set the maximum number of child processes
# 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

#具体设置MySQL认证的一些解释：
#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 DatabaseName@localhost:port root Password

#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。(需要在数据库中建立两张表用户和组"FTPUSERS""FTPGRPS"是数据表)
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

#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，FTPGRPS：
#mysql –h localhost –u root –p 123
mysql>create database FTP;
mysql>use FTP;
create table FTPUSERS (
userid TEXT NOT NULL, // userid是用做FTP服务的用户名
passwd TEXT NOT NULL, // passwd是指此用户的密码
uid INT NOT NULL, // uid是系统用户的ID,(所映射的系统用户ID)
gid INT NOT NULL, // gid是所属系统组的ID
homedir TEXT, //用户的宿主目录
shell TEXT //指定用户所用的shell ，（在具体应用时为安全做的）
);

create table FTPGRPS (
grpname TEXT NOT NULL, //grpname是组的名称
gid SMALLINT NOT NULL, // gid是系统组的ID
members TEXT NOT NULL, // members是组的成员（多成员用逗号隔开）
);
插入记录：
INSERT INTO FTPUSERS (userid, passwd, uid, gid, home, shell)
values ('unixsr', '2219118', '1000', '1000', '/FTP/unixsr', '' );
增加用户时按此格式你可以插入。
INSERT INTO FTPGRPS VALUES ('FTPGRPS', 1000, 'FTPUSR');
每当增加用户后，一定要在mysql更新FTPGRPS这个表的成员值
做法：
mysql>update FTPGRPS set members=’unixsr’,unixsr1,unixsr2’;
为FTP用户建立相应的系统用户。
# groupadd -g 1000 FTPGRP
# adduser -g 1000 FTPUSR
修改一下/etc/passwd
主要是把uid 和 gid 都改成1000 并把用户目录改为/FTP （我是手工改的，因为我的系统是三个硬盘做了一个RAID，挂到了/FTP 下，有命令的）
为FTPUSR建立HOME，unixsr 在此目录下：
mkdir /FTP/unixsr
chown FTPUSR /FTP/unixsr
chgrp FTPGRP /FTP/unixsr
当然在这里我仅做了一个用户，多个用户也是一样的，要注意目录属于系统的映射用户和组，

磁盘限额部分的一些解释：

#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 /var/log/Quota.log

# 打开磁盘限额信息.
QuotaShowQuotas on

#以下是SQL调用语句，不用修改直接拷贝过去 (这一部分拷贝网友)

SQLNamedQuery get-quota-limit SELECT "name, quota_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, //磁盘限额的类型
bytes_in_avail FLOAT NOT NULL, //FTP用户空间容量
bytes_out_avail FLOAT NOT NULL, //从服务器上下载的限制
bytes_xfer_avail FLOAT NOT NULL, //传输的文件的流量控制
files_in_avail INT UNSIGNED NOT NULL, //总共能上传文件的数目
files_out_avail INT UNSIGNED NOT NULL, //能从服务器上下载文件的总数目
files_xfer_avail INT UNSIGNED NOT NULL //总共可传输文件的数目(上传和下载)
);

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
);

给 unixsr帐号给予1M空间，最多能上传10个文件到服务器上，文件传输流量为20M，只能传输1个文件。（我这样设置仅为了测试，要根据自己的情况设置）
mysql>INSERT INTO `quotalimits` ( `name` , `quota_type` , `bytes_in_avail` , `bytes_out_avail` , `bytes_xfer_avail` , `files_in_avail` , `files_out_avail` , `files_xfer_avail` )
VALUES ('user1', 'user', '1024', '0', '2048000', '10', '0', '1');
注：不需要设置的部分用0代替就可以了
测试：
现在运行proftpd，登陆到unixsr ，使用quote SITE QUOTA 就会显示unixsr用户的磁盘使用情况

ftp> quote SITE QUOTA
200-The current quota for this session are [current/limit]:
Name: unixsr
Quota Type: User
Uploaded Kb: 0.00/1.00
Downloaded Kb: unlimited
Transferred Kb: 0.00/2000.00
Uploaded files: 0/10
Downloaded files: unlimited
Transferred files: 0/1
200 Please contact root@localhost if these entries are inaccurate
这次实验，我还做一把apache+php同porftp一起用，效果还可以：
在apache中只需把目录指向ftp用户的宿主目录，并且在httpd.conf中一定要把user和guoup 指定为FTPUSR FTPGRP,否则没有权限。

顶！！！好文章！！！
这样就能直接用php+mysql注册，然后就能ftp登陆了！！

好象没有有关ip功能。
