CakePHP Database connection “Mysql” is missing, or could not be created

Question

There have been several other posts about this, but none of the answers seemed to work for me.

When I navigate to the CakePHP page on my local machine, there is one

Answer 1

An alternative to unix_socket (especially for OS X people) is to replace localhost with 127.0.0.1

Would be as Follows :

public $default = array(
                'datasource' => 'Database/Mysql',
                'persistent' => false,
                'host' => '127.0.0.1',
                'login' => 'user',
                'password' => 'password',
                'database' => 'database-name',
                'prefix' => '',
                'encoding' => 'utf8',
        );

Answer 2

I tried splicing the code from Example 2 of http://php.net/manual/en/pdo.connections.php into /app/View/Pages/home.ctp. I had to fix the arguments the PDO constructor and change the name of the table in the query. The example 2 code returned the error "Error!: could not find driver". Based on King Jk's answer I was attempting to modify the php.ini when I started to wonder where a php_pdo_mysql.so might live. http://php.net/pdo_mysql showed how it was compiled as part of PHP via the --with-pdo-mysql option to configure. Recompiling fixed my problem. Note I'm working on a Ubuntu 12.10 system with PHP 5.5.9 and Apache Webserver 2.4.6

Answer 3

Because, cake bake use unix socket for connecting to database
so that you need add unix_socket for connection string.
You have to confirm location that store mysql.sock in WAS
Example: in my case i'm using xampp on MACOS 10.11
(edit file Config/database.php)

public $default = array(
  ‘datasource’ => ‘Database/Mysql’,
  ‘persistent’ => false,
  ‘host’ => ‘localhost’,
  ‘login’ => ‘root’,
  ‘password’ => ‘root’,
  ‘database’ => ‘cakephp’,
  ‘encoding’ => ‘utf8’,
  ‘unix_socket’ => ‘/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock’
);

Finally, It's work for me!

Answer 4

Edit php.ini and add:

extension=php_pdo_mysql.dll 

Then restart your web server

Answer 5

This error can also be caused if your connecting database user doesn't have the proper privileges. I believe you only need a minimum of INSERT, SELECT, UPDATE, and DELETE.

Always check username/password and the user privileges first since CakePHP will most likely give a vague database connection error for either.

Answer 6

Just to help Ubuntu users out: I had the same error in my ubuntu 13.10 machine with the newest xampp downlaoded directly from apachefriends. Tried most of the stuff in every post I could find about this error, but not the mac-specific stuff. In the end, the fix happened to be the same as the elected answer here:

Find the socket that mysqld creates for programs to connect to:

user@host /opt$ find . -name mysql.sock
/opt/lampp/var/mysql/mysql.sock

add it to your cakePHP database configuration file (cakePHP)/app/Config/database.php

'unix_socket' => '/opt/lampp/var/mysql/mysql.sock'

To me, this finally resulted in my cake commands being able to be executed without the "Error: Database connection "Mysql" is missing, or could not be created.".
