h1. Docs:ModDbiVhost
*Module: mod_dbi_vhost*
{{>toc}}
h2. Description
mod_dbi_vhost is a modified version of [[mod_mysql_vhost]] which instead uses "libDBI":http://libdbi.sf.net/ to read vhost to document root associations.
h2. Installation
This module is a 3rd party module and is not included in the official distribution. You can download the patch from here:
* For lighttpd 1.4.28: http://riverroadcable.com/~doneill/lighttpd-1.4.28-dbi.patch
Once applied, run autogen.sh and pass the option @--with-dbi@ to let the GNU tools find it, or @--with-dbi=/path/to/dbi@ to specify the location.
h2. Options
*vhost.dbi => ( "dbname" => "..." )* - Required
The name of the database for network database connections, or a database filename for local database implementations (Sqlite).
*vhost.dbi => ( "dbtype" => "..." )* - Required
Set this to your database type. This is usually included in the DBD file name. Eg., libdbdmysql.so is "mysql", and libdbdpgsql.so is "pgsql".
Some options include: _mysql_, _pgsql_, _sqlite3_, _freetds_, _sqlite_
*vhost.dbi => ( "sql" => "..." )* - Required
The actual query used to get the document root for a vhost. Use '?' in place of the hostname, for example:
<pre>
vhost.dbi += ( "sql" => "SELECT docroot FROM vhosts WHERE host='?'" )
</pre>
h2. Common Options
*vhost.dbi += ( "user" => "..." )* - Optional
The username to use for opening a typical network-based database connection.
*vhost.dbi += ( "pass" => "..." )* - Optional
A password used to authenticate to a database connection.
*vhost.dbi += ( "hostname" => "..." )* - Optional
A hostname used in establishing a database connection.
*vhost.dbi += ( "port" => _i_ i )* - Optional
A port number used to authenticate to a database connection. If not specified, the default for the specified database type will be used.
h2. MySQL-Specific Options
*vhost.dbi += ( "encoding" => "..." )* - Optional
For example, "@UTF-8@". This parameter compatibility and available options depend on the driver. I use it to tell the MySQL DBD to use UTF-8.
h2. Sqlite3-Specific Options
*vhost.dbi += ( "sqlite3_dbdir" => "..." )* - Required
The directory on the filesystem where the database file (specified in "dbname") is located.
h3. Examples
<pre># Sqlite3
vhost.dbi += (
"dbtype" => "sqlite3",
"dbname" => "lighttpd.db",
"sqlite3_dbdir" => "/etc/lighttpd",
"encoding" => "UTF-8",
"sql" => "SELECT docroot FROM vhosts WHERE host='?'"
)
# PostgreSQL
vhost.dbi += (
"dbtype" => "pgsql",
"dbname" => "lighttpd",
"user" => "postgres",
"hostname" => "localhost",
"encoding" => "UTF-8",
"sql" => "SELECT docroot FROM vhosts WHERE host='?'"
)
# MySQL
vhost.dbi += (
"dbtype" => "mysql",
"dbname" => "lighttpd",
"user" => "root",
"password" => "somepassword",
"hostname" => "localhost",
"encoding" => "UTF-8",
"sql" => "SELECT docroot FROM vhosts WHERE host='?'"
)
server.modules += ( "mod_dbi_vhost" )
</pre>
