I am currently reading ‘Beginning CakePHP:From Novice to Professional’ by David Golding. At one point I have to use the CLI-command ‘cake bake’, I get the welcome-screen but when I try to bake e.g. a Controller I get the following error messages:

Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2) in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 117  Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 122  Warning: mysql_get_server_info(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 130  Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 154 Error: Your database does not have any tables.

I suspect that the error-messages has to do with php trying to access the wrong mysql-socket, namely the default osx mysql-socket – instead of the one that MAMP uses. Hence I change my database configurations to connect to the UNIX mysql-socket (:/Applications/MAMP/tmp/mysql/mysql.sock):

class DATABASE_CONFIG {      var $default = array(         'driver' => 'mysql',         'connect' => 'mysql_connect',         'persistent' => false,         'host' =>':/Applications/MAMP/tmp/mysql/mysql.sock', // UNIX MySQL-socket         'login' => 'my_user',         'password' => 'my_pass',         'database' => 'blog',         'prefix' => '',     );  }

But I get the same error-messages with the new socket:

Warning: mysql_connect(): Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock:3306' (2) in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 117  Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 122  Warning: mysql_get_server_info(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 130  Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/blog/cake/libs/model/datasources/dbo/dbo_mysql.php on line 154 Error: Your database does not have any tables.

Also, even though I use the UNIX-socket that MAMP show on it’s welcome-screen, CakePHP loses the database-connection, when using this socket instead of localhost.

Any ideas on how I can get bake to work?

— Edit 1 —

Thank you guys for helping me out! 🙂

I have a problem figuring out where in my.cnf to edit to get MySQL to listen to TCP/IP request. The only paragraph I can find where TCP/IP is mentioned is the following: 

# Don't listen on a TCP/IP port at all. This can be a security enhancement, # if all processes that need to connect to mysqld run on the same host. # All interaction with mysqld must be made via Unix sockets or named pipes. # Note that using this option without enabling named pipes on Windows # (via the 'enable-named-pipe' option) will render mysqld useless! #  #skip-networking

That allows me to turn off TCP/IP completely, which is the opposite of my intention. I don’t know how to go about what you suggest, if you could be more elaborate it would be great. I am a total n00b on these matters :S

Reg. connecting to a local socket: I removed the leading colon in the host-parameter, same result.

  1. From the error, it looks like it’s trying to connect to an actual IP address and not a UNIX socket, look:

      '/Applications/MAMP/tmp/mysql/mysql.sock:3306'

    It’s appending a port to the socket, which is wrong.

    So, I’d first try to configure MySQL to listen to TCP/IP requests (edit the proper section in my.cnf) and try providing 127.0.0.1 instead of the socket.

    In case you won’t scroll down:

    To fix it at CakePHP level, change host on database.php to ‘localhost’ and add a port directive with its value set to the socket name ‘/Applications/MAMP/tmp/mysql/mysql.sock’
