proftp+mysql+quota的应用
1.首先我们建立相应的用户和用户组
groupadd -g 5500 ftpgroup
adduser -u 5500 -s /bin/false -d /bin/null -c "proftpd user" -g ftpgroup ftpuser
2.操作数据库
mysql mysql -uroot -ppassword
create database ftpdb
grant select, update on ftpdb.* to proftpd@localhost identified by 'password'
use ftpdb
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';
INSERT INTO `ftpgroup` VALUES ('ftpgroup', 5500, 'ftpuser');
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` 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'
) TYPE=MyISAM;
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;
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',
PRIMARY KEY (`id`)
) TYPE=MyISAM COMMENT='ProFTP user table' ;
注意这里大家根据实际情况填写自己数据库的用户名和密码,如果大家对数据库操作不熟悉的话,不妨可以用phpmyadmin来操作。
3.配置proftp文件
ServerName "Frank's FTP Server" ServerType standalone DefaultServer on
Port 21
Umask 022
MaxInstances 30
MaxLoginAttempts 3
User nobody
Group nobody
MaxHostsPerUser 1 "Sorry, you may not connect more than one time."
MaxClientsPerUser 2 "Only one such user at a time."
MaxClientsPerHost 3 "Sorry, you may not connect more than one time."
RootLogin off
RequireValidShell off
TimeoutStalled 10
MaxClients 10
AllowForeignAddress on
AllowStoreRestart on
ServerIdent off
DefaultRoot ~ ftpgroup
SQLAuthTypes Backend Plaintext
#Backend表示用户认证方式为MySQL数据库的认证方式
#Plaintext表示明文认证方式,排在最前面的为最先使用的方式
SQLAuthenticate users* groups*
# databasename@host database_user user_password
SQLConnectInfo ftpdb@localhost proftpd password
SQLUserInfo ftpuser userid passwd uid gid homedir shell
SQLGroupInfo ftpgroup groupname gid members
SQLHomedirOnDemand on
#如果用户主目录不存在,则系统会根据此用户在用户数据表中的homedir字段的值新建一个目录
# Update count every time user logs in
SQLLog PASS updatecount
SQLNamedQuery updatecount UPDATE "count=count+1,accessed=now() WHERE userid='%u'" ftpuser
# Update modified everytime user uploads or deletes a file
SQLLog STOR,DELE modified
SQLNamedQuery modified UPDATE "modified=now() WHERE userid='%u'" ftpuser
QuotaEngine on
QuotaDirectoryTally on
QuotaDisplayUnits Mb
QuotaShowQuotas on
QuotaLog "/var/log/quota"
SQLNamedQuery get-quota-limit SELECT "name, quota_type, per_session, limit_type, bytes_in_avail, bytes_out_avai
l, bytes_xfer_avail, files_in_avail, files_out_avail, files_xfer_avail FROM ftpquotalimits 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_i
n_used, files_out_used, files_xfer_used FROM ftpquotatallies 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}'" ftpquota
tallies
SQLNamedQuery insert-quota-tally INSERT "%{0}, %{1}, %{2}, %{3}, %{4}, %{5}, %{6}, %{7}" ftpquotatallies
QuotaLimitTable sql:/get-quota-limit
QuotaTallyTable sql:/get-quota-tally/update-quota-tally/insert-quota-tally
就这么简单,重启一下proftp服务就已经能使用proftp+mysql+quota的功能
我们可以在数据库ftpuser添加一个虚拟用户,
INSERT INTO `ftpuser` VALUES (1, 'test', 'ftppasswd', 5500, 5500, '/home/test', '/sbin/nologin');
大家可以在phpmyadmin里直接操作添加一个用户,相信不用我教大家怎么添加吧:)
如果你想设置quota,只要在ftpquotalimits表里设置一下就行了,这个表里的各个参数分别代表:
quotalimits表
name: - 用户帐号
quota type: - user, group, class, all (we use user)
per_session: - true or false (we use true)
limit_type: - 硬限制 or 软限制 (我们一般用硬限制)
bytes_in_avail: - 允许上传的字节数
bytes_out_avail: - 允许下载的字节数
bytes_xfer_avail: - 允许传输的字节数(包括上传/下载)
files_in_avail: - 允许上传的文件数
files_out_avail: - 允许下载的文件数
files_xfer_avail: - 允许传输的文件数(包括上传/下载)
mysql和quota模块来验证用户和设置磁盘限额,但我总觉得还是不够完善,因为在这个方法中,数据库表里还没有相应的权限的字段,所以说相应用户的权限还是得用实际得用户即mysql对应得uid和gid来控制权限。
