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 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:
{{{
$HTTP["host"] == "<DOMAIN_FROM_DATABASE>" {
<CONFIG_FROM_DATABASE>
}
}}}
mine looks like this:
{{{
#!/usr/bin/env python
import sys
import MySQLdb
# load configuration data from the database
db=MySQLdb.connect(host='localhost', db=sys.argv[1], user=sys.argv[2], passwd=sys.argv[3])
cur = db.cursor()
cur.execute("SELECT * FROM domains")
rs=cur.fetchall()
db.close()
for domain in rs:
print "$HTTP[\"host\"] == \"%s\" {\nserver.document-root = \"%s\"\n%s\n}" {\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.
