PDO connection error when using symfony and MAMP

Question

Getting an PDO error when trying to do php symfony doctrine:insert-sql
The error I get:

Warning: PDO::__construct(): [2002] Connection refused         


        

Answer 1

Looks right. Here would be the exact equivalent from a working databases.yml I'm using, in case it's of any use:

dsn: 'mysql:host=localhost;dbname=jobeet'

Answer 2

I had the same error when attempting to build my tables in Symfony and using MAMP. I fixed the issue by changing my dsn line, in the databases.yml file, to the following:

dsn: 'mysql:host=localhost;dbname=jobeet;unix_socket=/Applications/MAMP/tmp/mysql/mysql.sock'

Answer 3

MAMP by default doesn't allow TCP connections. You can either turn it on or use sockets.

Changing your dsn as @Tom suggests should fix your issues. Weird as it is but using localhost instead of 127.0.0.1 makes that mysql connects through sockets.

http://dev.mysql.com/doc/refman/5.0/en/connecting.html :

On Unix, MySQL programs treat the host name localhost specially, in a way that is likely different from what you expect compared to other network-based programs. For connections to localhost, MySQL programs attempt to connect to the local server by using a Unix socket file. This occurs even if a --port or -P option is given to specify a port number. To ensure that the client makes a TCP/IP connection to the local server, use --host or -h to specify a host name value of 127.0.0.1, or the IP address or name of the local server. You can also specify the connection protocol explicitly, even for localhost, by using the --protocol=TCP option.

MAMP PRO 2.x
I was able to solve this and many similar issues by simply unchecking "Allow local access only" in the MySQL prefs on the MAMP control panel.

MAMP PRO 3.x
