Question

I have put PushChatServer dir in htdocs folder and create database puschat try to run @\"http://localhost/PushChatServer/api/test/database.php\"

Then I got following

Answer 1

Just ran into this same issue and the problem is the password. In the tutorial the author lists the password as:

"d]682\#%yl1nb3"

So as per the suggestion given by @Marki555, I looked in the config file - api_config.php. and the password listed there is:

"d]682\#%yI1nb3"

The upper case 'I' is what caused the issue because the password you set for user on the db has the password with the lowercase l but it really is looking for the uppercase I. After I changed the pushchat user's password to have an uppercase i, it worked!

Answer 2

I had the same error for Mysql PDO, this code works for me!

<?php
$dsn = 'mysql:host=127.0.0.1;dbname=testdb';
$username = 'username';
$password = 'password';
$options = array(
    PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8',
); 

$dbh = new PDO($dsn, $username, $password, $options);
?>

got this code from : http://php.net/manual/en/ref.pdo-mysql.connection.php

I'm not sure if this will work for you; but I use CakePHP, and I get this error whenever I forget to put the port number at the end of the 'host'.

Hope this helps!

Before

'test' => [
        'className' => 'Cake\Database\Connection',
        'driver' => 'Cake\Database\Driver\Mysql',
        'persistent' => false,
        'host' => 'localhost',
        'username' => 'root',
        'password' => 'root',
        'database' => 'mylogin',
        'encoding' => 'utf8',
        'timezone' => 'UTC',
        'cacheMetadata' => true,
        'quoteIdentifiers' => false,
        'log' => false,
        //'init' => ['SET GLOBAL innodb_stats_on_metadata = 0'],
        'url' => env('DATABASE_TEST_URL', null),
    ]

After

'test' => [
        'className' => 'Cake\Database\Connection',
        'driver' => 'Cake\Database\Driver\Mysql',
        'persistent' => false,
        'host' => 'localhost:8080',
        'username' => 'root',
        'password' => 'root',
        'database' => 'mylogin',
        'encoding' => 'utf8',
        'timezone' => 'UTC',
        'cacheMetadata' => true,
        'quoteIdentifiers' => false,
        'log' => false,
        //'init' => ['SET GLOBAL innodb_stats_on_metadata = 0'],
        'url' => env('DATABASE_TEST_URL', null),
    ]

Answer 4

Restart your database and local web server:

• sudo service mysqld restart
• sudo service mysqld restart

It should work!

Answer 5

On Mac OSX/MAMP you may find a mysql.sock.lock file in your /Applications/MAMP/tmp/mysql folder.

You can safely remove the file mysql.sock.lock and you should be in good shape.

Answer 6

You need to change host from localhost to 127.0.0.1

Laravel 4: In your app/config/database.php try changing host from localhost to 127.0.0.1

Laravel 5: In the .env file, change DB_HOST from localhost to 127.0.0.1
