TYPO3 requires a web server, PHP and a database system.
- TYPO3 requires a web server which can run PHP (e.g. Apache or IIS).
- TYPO3 7.6 requires PHP 5.5 - 7.0.
- TYPO3 can be used with a great many database systems. If you use MySQL, you will need to implement at least MySQL 5.5.
If you use the Apache web server, the module mod_rewrite must be activated. Certain PHP extensions are necessary, others recommended. You possibly want to adjust the memory limit; at least 128 MB is recommended.
If you want TYPO3 to automatically carry out image processing – for example scaling or cropping – you will need GraphicsMagick or ImageMagick (version 6 or newer) installed on the server.
A detailed list of these requirements is enclosed in the file
INSTALL.md inside the TYPO3 source package.
Should you encounter problems, the "Troubleshooting" section at the end of this document will help.
