4 Configure Proftpd
Open /etc/proftpd.conf and add the following lines to it:
DefaultRoot ~ # The passwords in MySQL are encrypted using CRYPT SQLAuthTypes Plaintext Crypt SQLAuthenticate users* groups* # used to connect to the database # databasename@host database_user user_password SQLConnectInfo ftp@localhost proftpd password # Here we tell ProFTPd the names of the database columns in the "usertable" # we want it to interact with. Match the names with those in the db SQLUserInfo ftpuser userid passwd uid gid homedir shell # Here we tell ProFTPd the names of the database columns in the "grouptable" # we want it to interact with.

Make sure that you replace the string password with the real password for the MySQL user proftpd in the line SQLConnectInfo!
Restart Proftpd:
/etc/init.d/proftpd restart
Martin Mrajca has sent me these lines that you can add to /etc/proftpd.conf so that Proftpd sends you a banner with used / available space after LIST:
SQLNamedQuery gettally SELECT "ROUND((bytes_in_used/1048576),2) FROM ftpquotatallies WHERE name='%u'" SQLNamedQuery getlimit SELECT "ROUND((bytes_in_avail/1048576),2) FROM ftpquotalimits WHERE name='%u'" SQLNamedQuery getfree SELECT "ROUND(((ftpquotalimits.bytes_in_avail-ftpquotatallies.bytes_in_used)/1048576),2) FROM ftpquotalimits,ftpquotatallies WHERE ftpquotalimits.name = '%u' AND ftpquotatallies.name = '%u'" SQLShowInfo LIST "226" "Used %{gettally}MB from %{getlimit}MB. You have %{getfree}MB available space." |
Don't forget to restart Proftpd afterwards if you add these lines!
5 Populate The Database And Test
To populate the database you can use the MySQL shell:
mysql -u root -p
USE ftp;
First we create an entry in the table ftpgroup. It contains the groupname, the groupid and the username of the ftp group/user we created at the end of step two (replace the groupid appropriately if you use another one than 2001):
INSERT INTO `ftpgroup` (`groupname`, `gid`, `members`) VALUES ('ftpgroup', 2001, 'ftpuser');
Now we are done with the table ftpgroup. We do not have to create further entries here. Whenever you create a new virtual ftp user, you do this in the tables ftpquotalimits and ftpuser. So let us create our first user (we are still on the MySQL shell):
INSERT INTO `ftpquotalimits` (`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 ('exampleuser', 'user', 'true', 'hard', 15728640, 0, 0, 0, 0, 0);
INSERT INTO `ftpuser` (`id`, `userid`, `passwd`, `uid`, `gid`, `homedir`, `shell`, `count`, `accessed`, `modified`) VALUES (1, 'exampleuser', 'secret', 2001, 2001, '/home/www.example.com', '/sbin/nologin', 0, '', '');
quit;
(Do not forget to replace the groud- and userid 2001 appropriately in the last INSERT statement if you are using other values than in this tutorial!)
Now open your FTP client program on your work station (something like WS_FTP or SmartFTP if you are on a Windows system) and try to connect. As hostname you use server1.example.com (or the IP address of the system), the username is exampleuser, and the password is secret.
If you are able to connect - congratulations! If not, something went wrong.
Now, if you run
ls -l /home
you should see that the directory /home/www.example.com (exampleuser's home directory) has been automatically created, and it belongs to ftpuser and ftpgroup (the user/group we created at the end of step two).
To leave the MySQL shell, type
quit;
