Can't get going with MySQL in CakePHP

问题

This is my first time installing a framework, and I am pretty clueless.

I am on OSX 10.7 and I have the cakephp framework loaded into /Library/WebServer/Documents/cakephp and I have been able to load the test page and get rid of some of the errors and warnings. Right now I am trying to resolve this

  Warning (2): PDO::__construct() [pdo.--construct]: [2002] No such file or directory (trying to connect via unix:///var/mysql/mysql.sock) [CORE/Cake/Model/Datasource/Database/Mysql.php, line 160]
  Cake is NOT able to connect to the database.
  Database connection "SQLSTATE[HY000] [2002] No such file or directory" is missing, or could not be created.

I don't really know what to do here. I have installed MySQL. Does the MySQL PDO come installed on OSX by default? or do I need to install that? How can I check if that is installed if that seems to be the problem.

UPDATE:

The PDO Mysql driver is enabled. Also the phpinfo() for pro_mysql looks like this:

 Directive                     Local Value               Master Value
 pdo_mysql.default_socket   /var/mysql/mysql.sock   /var/mysql/mysql.sock

However the mysql directory doesn't appear in my filesystem. should I create it? or do I nee to change this path somewhere?

UPDATE: I think the problem is that I haven't actually set up a database. kindof dumb of me not to set up the database.

I guess I will try to figure that out now.

UPDATE:

The thing that finally solved this was that cake was looking for the Unix socket to the database in /var/mysql/mysql.sock but mysql was using the socket in /tmp/mysql.sock I fixed this by creating a symbolic link from the /var/mysql/mysql.sock to /tmp/mysql.sock.

It looks more like MySQL itself is not installed, but the PDO libraries are compiled with your webserver. I am not sure how to check this in OSX, but you can try checkign this link out: http://www.sequelpro.com/docs/Install_MySQL_on_Mac_OS_X

EDIT

Log into MySQL (mysql -u root -p) and create the databas:

create database cakephp

Then create a new username/password and grant them access to this database. Let's say you want to create the username cakephp and the password cakepass:

GRANT ALL ON cakephp.* TO cakephp@localhost IDENTIFIED BY 'cakepass';
FLUSH PRIVILEGES;

And now your database.php config file should look like this:

<?php
class DATABASE_CONFIG {
    public $default = array(
        'datasource'  => 'Database/Mysql',
        'persistent'  => false,
        'host'        => 'localhost',
        'login'       => 'cakephp',
        'password'    => 'cakepass',
        'database'    => 'cakephp',
        'prefix'      => ''
    );
}

回答2:

No, MySQL does not come with OSX, you'll have to install it.

The easiest solution is to use XAMPP instead of compiling/installing MySQL yourself. It will also come with a separate Apache and PHP, if you don't want to mess with the native OSX versions.
