I want to connect to an external Database on another Host (not localhost) on Drupal because i want to migrate Content with the Migrate Module.
thats in my settings.php
$databases['for_migration']['default'] = array(
'driver' => 'mysql',
'database' => 'dbname',
'username' => 'username',
'password' => 'password',
'host' => 'other-host.com',
'prefix' => '',
'port' => '',
);
And in another method im calling the database via:
$query = Database::getConnection('default', 'for_migration')
thats the error which appears:
PDOException: SQLSTATE[HY000] [2003] Can't connect to MySQL server on 'host.com' (13) in MigrateMigration->__construct() (Zeile 16 von /var/www/html/x/sites/all/modules/migrate_x/x.inc).
So if i call a database on localhost, there are no errors and all migrates perfectly. But i cant connect to a database on an external host.
That could be due to:
1) connection limitation (firewall block, for example).
2) the account you are using does not allows logins outside of "localhost". In this case, you will have to edit your account hostname mask on the 'user' table inside the 'mysql' database for '%' (which means, any address) or the machine IP address you are accessing from.
It was my fault. I have set httpd_can_network_connect on the remote server to on.
But the solution was to set it on my local machine. After that i can connect to an external Host. So it was a SELinux Problem.
Thanks to #fobia

I can`t find too much documentation about connecting Drupal7 website with SQL Google database. Does anybody have experience with it? I trying to split Drupal website on VM instance and mysql database on SQL Google storage. After that, change settings.php in Drupal:
$databases['default']['default'] = array(
'database' => 'DATABASE',
'username' => 'USERNAME',
'password' => 'PASSWORD',
'host' => 'Public_IP_of_Google_SQL',
'driver' => 'mysql',
'port' => 3306 (I try 1433 also),
'prefix' => '',
);
}
On SQL instance I have enabled firewall for tcp ports:3306,1433
However, I always get error
PDOException: SQLSTATE[HY000] [2002] Connection refused in lock_may_be_available() (line 167 of /home/public_html/includes/lock.inc).
Can anybody help? What can I do on Drupal side to connect website with external database?
I need my Laravel project to use a database that is on a virtual machine on another network.
I know there's two database configuration on
app/config
app/config/local
I'm using MySql, how should I configure the database.php file?
Right now is configured to my local:
'mysql' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'db_name',
'username' => 'root',
'password' => 'the_password',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
You should specify remote MySQL server host IP address in database.php configuration.
Also you need to make sure you have enable remote connection to your MySQL database (normaly most MySQL servers are restricted to connections only from localhost). For this purpose you will need to create new database user with the following command
GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'#'IP' IDENTIFIED BY 'PASSWORD';
Where you put IP of the server where you laravel installation is located.
Also after that you must execute
FLUSH PRIVILEGES;
And the you can connect to remote database.
I'm getting this error when trying to connect to an SQL Server DB from Laravel 4.2.
Here's my DB config:
'connections' => array(
'sqlsrv' => array(
'driver' => 'sqlsrv',
'host' => 'example.noip.me',
'database' => 'db',
'username' => 'sa',
'password' => 'pass',
'prefix' => '',
),
),
//...
It works perfectly in my home computer, but not in production. This project is in a hosting service, so I can't change much of the config (can still use ini_set though).
I tried adding the port to the server address but it didn't work.
Edit: I forgot to mention that the hosting and the database server are on different computers, so it could be a security configuration problem.
I contacted tech support and it turned out to be a matter of configuration in the hosting server (Remote Database Access Hosts, which I thought was for MySQL only).
Okay so i am trying to connect to my remote SQL database.
i am using the following settings:
public $default = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => '10.246.16.153:3306',
'login' => '*******',
'password' => '*******',
'database' => 'udlejnings_pris',
'prefix' => '',
//'encoding' => 'utf8',
);
My Database settings are the following:
Database server
Server: 10.246.16.153 via TCP/IP
Software: MySQL
Software version: 5.1.66-0+squeeze1 - (Debian)
Protocol version: 10
Server charset: UTF-8 Unicode (utf8)
Now when im trying to access this server i get the following error:
2013-10-12 16:27:28 Error: [MissingConnectionException] Database connection "Mysql" is missing, or could not be created.
Exception Attributes: array (
'class' => 'Mysql',
'message' => 'SQLSTATE[HY000] [2002]
',
'enabled' => true,
)
So what am i doing wrong?
Many hosted MySQL instances don't allow clients to connect remotely by default. You may need to add your IP address into some form of Remote MySQL option if your database host provides it. For example, if the server with the database on it uses cPanel, there is a 'Remote MySQL' option on there which may resolve your issue. Alternatively, you could execute the 'GRANT' SQL command to allow your user account access remotely as described in this answer.
If you still have issues, a firewall may be blocking the connection locally too.
Maybe you need to enable mysql remote access on the server that you are connecting to. By default it is disabled.

I understand this problem has been a recurring problem on this site, but my issue is a little different than the previous ones.
PROBLEM
Some pages use the correct socket directory, while other pages try and connect through an incorrect socket directory or this is what I believe the problem is based on the error i am receiving.
DETAILS
HOST: example.com
cakePHP version: 1.3.2 (Not my choice).
Page's content comes from database.
URL: http://example.com
My website has 2 sections:
anonymous section
login section for members or admin
The anonymous section works. It accesses the database, adds the content, and funcitons as it should.
ERROR
The error occurs when I click a link "view more.." under "Job Links" on the home page. A login form should pop up, instead i receive the error "cannot connect to local MySql server through socket '/var/run/mysqld/mysqld.sock' (2)".
In addition, after I login via the "Members login" button, also on the home page, with the correct credentials, it also produces the same error.
QUESTION
Why would different sections on my webpage try to access the sockets through different directories?
ADDITIONAL STUFF
I signed up today and this is my first post, so feedback on my post regarding enough information would be helpful for future posts.
Thanks for your time.
UPDATE
Upon further research, MySql has been using the socket directory /var/run/mysqld/mysqld.sock from the start. Not sure what this means yet, but continuing research..
database.php file
class DATABASE_CONFIG {
var $default = array(
'driver' => 'mysqli',
'persistent' => true,
'host' => 'redlabelcom.netfirmsmysql.com',
'login' => 'bcp',
'password' => '********',
'database' => 'bcp',
'prefix' => '',
'encoding' => 'UTF8',
//'socket' => '/var/run/mysqld/mysqld.sock', // I've tried commenting out all variations of socket and port
//'port' => '/var/run/mysqld/mysqld.sock', // nothing works.
);
var $test = array(
'driver' => 'mysqli',
'persistent' => false,
'host' => 'redlabelcom.netfirmsmysql.com',
'login' => 'bcp',
'password' => '********',
'database' => 'bcp',
'prefix' => '',
'encoding' => 'UTF8',
//'port' => '/var/run/mysqld/mysqld.sock',
);
}
?>
This problem is really strange. I guess this has something to do with mysql connection. MySQL is a daemon, usually configured in /etc/mysql/my.cnf. There you define how the client will connect the MySQL server:
[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock
If your socket is wrong (there's no such socket on the server), you are probably connecting different mysql host/port from anonymous/secured parts of application. This is possible (I mean different db connections from different application parts). Check your configuration (host, port, etc.) and try to connect from MySQL console:
$ mysql -h hostname -u username -p dbname # enter password
and check if you can connect. If you can connect from console, you'll surely connect from any server-side application (php, python, whatever).
It's an application that someone else was developing, right, and now you have to maintain it?
PROBLEM SOLVED!
Thanks everyone for your support!
This was an interesting issue that initially looked more complicated than the actual problem.
cakephp version 1.3.2 is set up to make a new connection to the database if you need to access the phpbb data fields. The new connection uses a different configuration than what is set up in the database.php file.
Below is a detailed description with file locations.
the 'app/webroot/discussion/common.php' file makes a NEW connection to the database using a different set of MySql parameters than the database.php file. Again, it does NOT use database.php's MySql configuration.
Instead, cakephp defines new connection variables located at:
'app/webroot/discussion/config.php'
To solve the problem, simply change the
$dbhost => localhost -> $dbhost => yourservername
$dbname => wrongname -> $dbname => rightname
etc..
Keep in mind that it is possible the previous developer changed these values, so if this doesn't help you then good luck.
BTW, the error message above was the result of trying to connect to localhost.
To resolve this issue, I ran the following commands:
mysqld --tc-heuristic-recover=ROLLBACK
systemctl start mariadb.service
