How to configure TYPO3

Local configuration is done by overriding default values in the included file, typo3conf/LocalConfiguration.php. In this file you enter the database information along with values in the global array TYPO3_CONF_VARS.
The options in the TYPO3_CONF_VARS array and how to use it for your own purposes is discussed in the base configuration file, EXT:core/Configuration/DefaultConfiguration.php. This file sets up the default values and subsequently includes the LocalConfiguration.php file in which you can then override values.
See this page for more information about system requirements.


Using this script

There are three primary steps for you to take:

1: Basic Configuration
In this step your PHP-configuration is checked. If there are any settings that will prevent TYPO3 from running correctly you'll get warnings and errors with a description of the problem.
You'll have to enter a database username, password and hostname. Then you can choose to create a new database or select an existing one.
Finally the image processing settings are entered and verified and you can choose to let the script update the configuration with the suggested settings.

2: Database Analyser
In this step you can either install a new database or update the database from any previous TYPO3 version.
You can also get an overview of extra/missing fields/tables in the database compared to a raw sql-file.
The database is also verified against your configuration ($TCA) and you can even see suggestions for entries in $TCA or new fields in the database.

3: Upgrade Wizard
Here you will find update methods taking care of changes to the TYPO3 core which are not backwards compatible.
It is recommended to run this wizard after every update to make sure everything will still work flawlessly.

4: Image Processing
This step is a visual guide to verify your configuration of the image processing software.
You'll be presented to a list of images that should all match in pairs. If some irregularity appears, you'll get a warning. Thus you're able to track an error before you'll discover it on your website.

5: All Configuration
This gives you access to any of the configuration options in the TYPO3_CONF_VARS array. Every option is also presented with a comment explaining what it does.

6: Cleanup
Here you can clean up the temporary files in typo3temp/ folder and the tables used for caching of data in your database.
