How to Resolve the \'CakePHP Database Connection \'Mysql\' Missing\' Error: Missing Socket Configuration?

Solving "CakePHP Database Connection "Mysql" Missing" Error

Despite reviewing existing discussions, some users still encounter the error "CakePHP is NOT able to connect to the database. Database connection "Mysql" is missing, or could not be created."

Error Investigation

To investigate, the error message "Error!: SQLSTATE[42000] [1049] Unknown database 'test'" indicates that CakePHP is unable to find the specified database.

Reviewing Database Configuration

Examining the database connection configuration in Users/Ben/Sites/myapp/app/Config/database.php reveals the following settings:

<code class="php">$default = array(
        'datasource' => 'Database/Mysql',
        'persistent' => false,
        'host' => 'localhost',
        'login' => 'Ben',
        'password' => 'mypass',
        'database' => 'CV',
    );</code>

These settings seem to be correct, and a MySQL user named Ben with the password mypass and a database named CV have been created.

Solution

In some cases, the issue may lie with the socket configuration. Try adding the following line to the database configuration:

<code class="php">'unix_socket' => '/Applications/MAMP/tmp/mysql/mysql.sock',</code>

This line specifies the path to the MySQL socket. The path may vary depending on your specific setup and operating system.

With this change, CakePHP should be able to successfully establish a connection to the MySQL database.
