Contao is an Open Source PHP Content Management System for people who want a professional website that is easy to maintain. Visit the project website for more information.

System Requirements

Web server
PHP 8.1+ with GDlib and DOM
MySQL 5.5.7+
InnoDB with innodb_large_prefix enabled

InnoDB Large Prefix

MySQL versions prior to 5.7.7 do not have the innodb_large_prefix option enabled by default. To enable it in one of these versions, add the following to your my.cnf file:

innodb_large_prefix = 1
innodb_file_format = Barracuda
innodb_file_per_table = 1

If the option cannot be enabled on your server, please configure a different database engine and character set in your config/config.yml file:

doctrine:
    dbal:
        connections:
            default:
                default_table_options:
                    charset: utf8
                    collate: utf8_unicode_ci
                    engine: MyISAM

MySQL Strict Mode

It is recommended to run MySQL in "strict mode" to prevent corrupt or truncated data and to guarantee data integrity. As of Contao 4.12, the install tool shows a warning if the database server is not running in strict mode. To enable it, add the following to your my.cnf file or make sure that the setting is adjusted accordingly:

[mysqld]
…
sql_mode="TRADITIONAL"
…

If the setting cannot be enabled on your server, please configure the connection options in your config/config.yml file:

doctrine:
    dbal:
        connections:
            default:
                options:
                    # Depending on the DB driver, the option key is either 1002 (pdo_mysql) or 3 (mysqli)
                    1002: "SET SESSION sql_mode=(SELECT CONCAT(@@sql_mode, ',TRADITIONAL'))"
