Requirements

TYPO3 needs:

• a web server - usually Apache is used
• a database server, for which most often MySQL is used but with the dbal? system extension PostgreSQL? or Oracle? can also be used
• the PHP scripting language, for TYPO3 versions up to 4.5? PHP 5.2? is required, for TYPO3 4.6? at least PHP 5.3? is required.

Default admin account

Upon installation TYPO3 creates a default admin user for the backend. This user has the username: admin and the password: password

One should immediately change the password of the admin user as leaving it with the default value could create a very high security risk.

Install Tool

The TYPO3 Install Tool is used to configure the TYPO3 instance according to the users needs. The Install Tool is also protected with a default password which is joh316 (This comes from a bible verse: The Gospel of John, Chapter 3, Verse 16).

This password should also be changed immediately in order to prevent unauthorized access to this tool!

A few conventions in the TYPO3 tables

• In every TYPO3 table the field uid denotes the unique identifier of a record.
• Similarly the pid field contains the parent page of the current database element.
• When a record is deleted from the backend it will be actually kept in the database but the field deleted will be set to 1

Making a backup

There are several ways for creating a backup of a TYPO3 website

• By making a backup of the database dump and an archive of the document root directory (this is the safest way of making a backup)
• By right-clicking on the globe in the page tree and using the More Options -> Export to ((.t3d))
• By using a custom built extension either obtained from the TER? or created by a third party
