ProFTPd+MySQL howto

Proftpd with Mysql backend -command list

This is a quick and dirty proftpd+mysql setup Howto. It lets you setup a ProFTPd server with a MySQL backend so you can manage ftp users on a server from a database.

• wget ftp://ftp.proftpd.org/distrib/source/proftpd-1.3.0a.tar.gz
• tar -zxf proftpd-1.3.0a.tar.gz
• cd proftpd-1.3.0a
• make dist clean
• ./configure –with-modules=mod_sql:mod_sql_mysql:mod_quotatab:mod_quotatab_sql –with-includes=/usr/include/mysql –with-libraries=/usr/lib/mysql
• make
• make install
• ln -s /usr/local/sbin/proftpd /usr/sbin/proftpd
• groupadd nogroup
• groupadd -g 5500 ftpgroup
• adduser -u 5500 -s /bin/false -d /bin/null -c “proftpd user” -g ftpgroup ftpuser
• mysql -u root -p

create database ftpdb;
grant select, insert, update on ftpdb.* to proftpd@localhost identified by ‘password’;

proftpd -td5 —-config check

proftpd -nd6 —– debug mode

/etc/init.d/proftpd restart

Now if you add users to the ftpusers table you should be able to login with those credentials without having to do anything else.

Please feel free to contact me if you run into a problem while setting this up.
