Deploying TYPO3

This guide outlines the steps required to manually deploy TYPO3 and ensure the installation is secure and ready to be used in a production context. This guide also highlights a number of automation tools that can help automate the deployment process.

There are several different ways to deploy TYPO3. One of the more simple options is to manually copy its files and database from a local machine to the live server, adjusting the configuration where necessary.

General Deployment Steps

Build the local environment (installing everything necessary for the website)
Run composer install --no-dev to install without development dependencies
Copy files to the production server
Copy the database to the production server
Clearing the caches

Note

The composer install command should not be run on the live environment. Ideally, Composer should only run locally or on a dedicated deployment machine, to allow testing before going live.

To avoid conflicts between the local and the server's PHP version, the server's PHP version can be defined in the composer.json file (e.g. {"platform": {"php": "8.1"}}), so Composer will always check the correct dependencies.
