CakePHP 2.0 : Database connection “Mysql” is missing, or could not be created

问题:

following the installation of CakePHP 2.0 (modified, I said that I get the same problem on a clean install of cakephp 2.0) I found myself facing an error I have not been able to solve.

configuration:

server : debian weezy 7

user : test

structure : /wwwjail/siteroot/test/htdocs/[app/...]

nginx configuration

cat /etc/nginx/sites-available/test

server {     listen IP:80 default;     server_name domain.fr;     access_log /var/log/nginx/test.access.log;     error_log  /var/log/nginx/test.error.log;      autoindex off;     index index.php index.html;     root /wwwjail/siteroot/test/htdocs/;      location ~ \.php$ {                         try_files $uri =404;                          fastcgi_intercept_errors on;                         fastcgi_pass unix:/wwwjail/siteroot/test/php-fpm.sock;                          include /etc/nginx/fastcgi_params;                         fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;     } } 

php5-fpm configuration

cat /etc/php5/fpm/pool.d/test.conf

On the mysql database credentials are correct, the user mysql user-test exist and full access to test.*

cat /wwwjail/siteroot/test/htdocs/app/Config/database.php

class DATABASE_CONFIG {      public $default = array(         'datasource' => 'Database/Mysql',         'persistent' => false,         'host' => '127.0.0.1',         'login' => 'user-test',         'password' => 'mypassword',         'database' => 'test',         'prefix' => '',         'encoding' => 'utf8'     ); } 

Checking the connection with the config file of CakePHP (script found on stackoverflow)

<?php include("app/Config/database.php"); $config= new DATABASE_CONFIG();  $name = 'default';  $settings=$config->{$name}; $dsn = 'mysql:dbname='.$settings['database'].';host='.$settings['host']; $user = $settings['login']; $password = $settings['password'];  try {     $dbh = new PDO($dsn, $user, $password);     echo "Connection succeeded with dsn: ". $dsn . "\n";     $sql = 'SELECT id, title FROM posts';     echo "Here is the contents of the table `posts:";     foreach ($dbh->query($sql) as $row) {         print $row['id'] . "\t" . $row['title'] . "\n";     } } catch (PDOException $e) {     echo 'PDO error: ' . $e->getMessage(); }  ?> 

====> return: Connection succeeded with dsn: mysql:dbname=test;host=127.0.0.1 Here is the contents of the tableposts:`

Checking socket with php.ini

*grep -i 'default_socket' /etc/php5/fpm/php.ini*

default_socket_timeout = 60 pdo_mysql.default_socket= /wwwjail/var/run/mysqld/mysqld.sock mysql.default_socket = /wwwjail/var/run/mysqld/mysqld.sock  mysqli.default_socket = /wwwjail/var/run/mysqld/mysqld.sock 

Verification of the existence of the PDO extension.

var_dump( extension_loaded('pdo_mysql') ); 

return => bool(true)

I hope I have provided much information about my problem. I am willing to perform various manipulations to test. (I think a problem server side configuration necessarily, although this configuration works for other basic applications connecting to mysql also).

Sincerely.

回答1:

In your /app/Config/database.php file, change the following line:

'host' => 'localhost', 

to:

'host' => '127.0.0.1', 

回答2:

In case you haven't solved this yet: I had the same error in my ubuntu 13.10 machine with the newest xampp downloaded directly from apachefriends. Try this:

Find your mysql.sock:

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.".

回答3:

In database.php you need to create a variable array for test database like so:

public $test = array(     'datasource' => 'Database/Mysql',     'persistent' => false,     'host' => 'localhost',     'login' => 'root', // what ever you have as user      'password' => '', // what ever you have as pass     'database' => 'test',     'prefix' => '',     'encoding' => 'utf8', ); 

Then crucially make sure you have an empty database called:

test 

That error message is quite deceiving should really say "Missing database test" :) well in my case this was the issue.

回答4:

Try this and make sure you are using correct username and password

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

回答5:

Create connection credentials to mysql via phpmyadmin if its set to be empty. That worked for me
