Installing TYPO3

Pre-installation Checklist

• Command line (CLI) access with the ability to create directories and symbolic links.
• Access to Composer via the CLI (for local development)
• Access to the web server's root directory
• Database with appropriate credentials

Execute Composer Create-Project

Execute this Composer command in the web server's root directory.

composer create-project typo3/cms-base-distribution example-project-directory "^11"

composer create-project "typo3/cms-base-distribution:^11" example-project-directory

# Create a directory for your project
mkdir example-project-directory

# Go into that directory
cd example-project-directory

# Tell DDEV to create a new project of type "typo3"
# 'docroot' MUST be 'public'
ddev config  --project-type=typo3 --docroot=public

# Start the ddev instance
ddev start

# Fetch a basic TYPO3 installation composer.json
ddev composer create "typo3/cms-base-distribution:^11" --no-install -y

# And do the installation
ddev composer install

This command pulls down the latest release of TYPO3 and places it in the example-project-directory.

After this command has finished running, example-project-directory will contain the following structure:

.
├── .gitignore
├── composer.json
├── composer.lock
├── LICENSE
├── public
├── README.md
├── var
└── vendor

Verify Installation

Create an empty file called FIRST_INSTALL in the /public directory:

touch example-project-directory/public/FIRST_INSTALL

echo $null >> public/FIRST_INSTALL

ddev exec touch public/FIRST_INSTALL

.
├── .gitignore
├── composer.json
├── composer.lock
├── LICENSE
├── public
    ├── FIRST_INSTALL
├── README.md
├── var
└── vendor

Access TYPO3 via a web browser

After you have configured your web server to point at the public directory of your project, TYPO3 can be accessed via a web browser. When accessing a new site for the first time, TYPO3 automatically redirects all requests to /typo3/install.php to complete the installation process.

Scan Environment

TYPO3 will now scan the host environment. During the scan TYPO3 will check the host system for the following:

• Minimum required version of PHP is installed.
• Required PHP extensions are loaded.
• php.ini is configured.
• TYPO3 is able to create and delete files and directories within the installation's root directory.

If no issues are detected, the installation process can continue.

In the event that certain criteria are not met, TYPO3 will display a list of issues it has detected accompanied by a resolution for each issue.

Once changes have been made, TYPO3 can re-scan the host environment by reloading the page https://example.org/typo3/install.php.

Select A Database

Select a database connection driver and enter the credentials for the database.

TYPO3 can either connect to an existing empty database or create a new one.

The list of databases available is dependent on which database drivers are installed on the host.

For example, if an instance of TYPO3 is intended to be used with a MySQL database then the PHP extension 'pdo_mysql' is required. Once it's installed, 'MySQL Database' will be available as an option.(Review)

Create Administrative User & Set Site Name

An administrator account needs to be created to gain access to TYPO3's backend.

An email address for this user can also be specified and a name can be given.

Initialise

TYPO3 offers two options for initialisation: creating an empty starting page or it can go directly to the backend administrative interface. Beginners should select the first option and allow TYPO3 to create an empty starting page. This will also generate a site configuration file.

Next Steps

Now that installation is complete, TYPO3 can be configured.

Using DDEV

We also provide a step-by-step tutorial on how to Install TYPO3 using DDEV. The tutorial also includes a video.
