Doctrine cannot connect to database in Symfony2 using Mamp
<p>I'm trying to create database through doctrine.</p>

<pre><code>php app/console doctrine:database:create
</code></pre>

<p>When I run the command above, I receive the following errors:</p>

<pre><code>[Doctrine\DBAL\Exception\ConnectionException]                              
An exception occured in driver: SQLSTATE[HY000] [2002] Connection refused  



[Doctrine\DBAL\Driver\PDOException]        
SQLSTATE[HY000] [2002] Connection refused  



[PDOException]                             
SQLSTATE[HY000] [2002] Connection refused
</code></pre>

<h2>What I have tried</h2>

<p>This symbolic link creation did not work for me.</p>

<pre><code>sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock mysql.sock
</code></pre>

<p>I've tried with both
<code>database_host: localhost</code> and <code>database_host: 127.0.0.1</code> nothing changed.</p>

<p>I know that my MySQL port is <code>8889</code> as I can see on MAMP.</p>

<p>I could not check the option <strong>Allow network access to MySQL</strong> under MySQL tab on MAMP since I do not have <strong>MAMP Pro</strong></p>
