Preparing setup

Unpack the TYPO3 source as usual, and unpack a dummy package. Set everything up as explained in the setup documentation, until you come to the point where you are asked to start the install tool – DON’T DO THIS YET!

Extensions DBAL and ADOdb are part of the system extensions shipped with TYPO3. As such, you only have to load them.

Edit the file typo3conf/localconf.php and append “adodb,dbal” to the comma-separated list of extensions found in $TYPO3_CONF_VARS['EXT'] . Another option is to add following code to the end of the file:

$TYPO3_CONF_VARS['EXT']['extList'] .= ',adodb,dbal';

Now add following code to the end of the same file typo3conf/localconf.php :

$TYPO3_CONF_VARS['EXTCONF']['dbal']['handlerCfg'] = array(
    '_DEFAULT' => array(
        'type' => 'adodb',
       'config' => array(
           'driver' => 'mysql',
       )
   ),
);

Of course you need to adjust the DBAL configuration as you need to, the example above does nothing but route everything through ADOdb inside the DBAL extension. See appendices for specific DBMS setup tutorials.
