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.hostname overrides mysql-vhost.sock.

MySQL setup: ::

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


Wildcard subdomains simple
I had a problem, i have webhosts with wildcard subdomains like *, and i have the files in the same directory. I wanted to have the same functionality like spamassassin has in the SQL config, so a domain name in the SQL like '' works. Here's the query that solves this problem: {{{
mysql-vhost.sql = "SELECT docroot FROM domains WHERE '?' like domain;"
}}} Per-vhost configuration

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

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/ 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/, which just prints the info. You could write this in perl, php, or bash, if you want.

it should output this format:


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")

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.
