MySQL-based vhosting ====================

-----------------------
Module: mod_mysql_vhost
-----------------------

.. meta::
:keywords: lighttpd, mysql, vhost

.. contents:: Table of Contents

Description ===========

With MySQL-based vhosting you can store the path to a given host's
document root in a MySQL database.

.. note:: Keep in mind that only one vhost module should be active at a time.
Don't mix mod_simple_vhost with mod_mysql_vhost.

Options =======

Example: ::

mysql-vhost.db             = "lighttpd" 
  mysql-vhost.user           = "lighttpd" 
  mysql-vhost.pass           = "secret" 
  mysql-vhost.sock           = "/var/run/mysqld/mysqld.sock" 
  mysql-vhost.sql            = "SELECT docroot FROM domains WHERE domain='?';" 
  mysql-vhost.hostname           = "localhost" 
  mysql-vhost.port           = 3306

If specified, mysql-vhost.host overrides mysql-vhost.sock.

MySQL setup: ::

GRANT SELECT ON lighttpd.* TO lighttpd@localhost IDENTIFIED BY 'secret';

CREATE DATABASE lighttpd;

USE lighttpd;

CREATE TABLE domains (
    domain varchar(64) not null primary key,
    docroot varchar(128) not null
  );

INSERT INTO domains VALUES ('host.dom.ain','/http/host.dom.ain/');

}}}

Per-vhost configuration

I wanted to be able to add configuration directives per vhost. This is how I did it.

{{{
CREATE TABLE IF NOT EXISTS domains (
domain varchar(64) NOT NULL PRIMARY KEY,
docroot varchar(128) NOT NULL,
config text
);
}}}

then I added this line to my mysql-vhost.conf (but you can use lighttpd.conf)

{{{
include_shell "/usr/share/lighttpd/mysql_vhost.py lighttpd lighttpd secret"
}}}

the parameters are just the info above. I didn't know how to pass the actual variables (maybe someone else does?) so I just repeated their values.

I then made a script called /usr/share/lighttpd/mysql_vhost.py, which just prints the info. You could write this in perl, php, or bash, if you want.

it should output this format:

{{{
$HTTP["host"] == "<DOMAIN_FROM_DATABASE>" {
<CONFIG_FROM_DATABASE>
}
}}}

mine looks like this:

{{{
#!/usr/bin/env python
import sys
import MySQLdb

1. load configuration data from the database
   db=MySQLdb.connect(host='localhost', db=sys.argv¹, user=sys.argv², passwd=sys.argv³)
   cur = db.cursor()
   cur.execute("SELECT * FROM domains")
   rs=cur.fetchall()
   db.close()

for domain in rs:

print "$HTTP[\"host\"] == \"%s\" {\nserver.document-root = \"%s\"\n%s\n}" % (domain[0], domain[1], domain[2])
}}}

Now, you can put whatever directives you want in the config field.
Make sure to restart your server to enable the settings, if you change them in the database.
