I want to access a Mysql data the first step is to create a new table for "vanvlymen" and I typed mysql> USE vanvlymen; the database changed. and type SHOW tables; showing the available of the tables that the database contains.
mysql -u root -p
enter password: ****
mysql> show databases;
-databases-
information_schema
mysql
performance_schema
phpmyadmin
vanvlymen
5 rows...
everything is looking good...
I have decide to tell mysql to specify the database I am working on before executing the query as "vanvlymen"
app/config/database.php
'mysql' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'vanvlymen',
'username' => 'foobar',
'password' => 'foobar',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
save as file go to FileZilla using FTP find a file drag and drop into my live server overwrite the database.php file.
I have tried to clear the cache like that
php artisan cache:clear
php artisan migrate
it errors:
SQLSTATE[42000] [1049] unknown database 'forge'.
Why keeping it said unknown database 'forge' I am excepting to change to vanvlymen database. Should I remove mysql and reinstall?
I am using windows 8.1 with laravel 4.2
Using phpmyadmin, I know what is the password and username to log in.
remove two files config.php and services.php in /bootstrap/cache. And try again.
Do you have something like app/config/yourEnvironment/database.php ?
For example local or production. 'forge' is default name of DB in this config file, so it looks like your app is loading wrong config file.
Hopefully this will help someone else. I suddenly had an issue where my dev site I was building stopped connecting to the DB, and just as the OP it was saying:
PDOException SQLSTATE[HY000] [1049] Unknown database 'forge' failed
After much head scratching (!) I found that my hostname value set inside the /bootstrap/start.php was wrong, because my hostname had changed on my macbook pro!? I have no idea how but it changed from something like RobMacbookPro2.local to RobMacbookPro.local. This meant it fell back to production thus loading the incorrect database.php file with the standard DB=forge (which was wrong)
Check this guide:
http://laravel.com/docs/4.2/configuration
Pay particular attention to the code:
<?php
$env = $app->detectEnvironment(array(
'local' => array('your-machine-name'),
));
On a mac and probably linux? you can determine your hostname by typing # hostname in terminal.
Hope that saves someone some time!
If you are running both Xampp and MySQL Workbench, or if You are Running Xampp on the port other than the default port, there may be chances of confusion, you may have created the database using PHPMyAdmin and you are trying to connect it to localhost:cusotmport (e.g. localhost:8080).
what I suggest is to create the database you want using MySQL workbench and then you would get your task done...

As you can already see in the title I want to connect to a PostgreSQL Database I created on a server using PHP and Yii2. Unfortunately I am a total novice when it comes to this kind of job and I have never done it before so I have several questions that I hope some of you can answer.
I am using Yii2 basic and in the config directory there is a db.php file containing the following code:
return [
'class' => 'yii\db\Connection',
'dsn' => 'pgsql:host=localhost;dbname=my1DB',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
];
Is the code actually OK? Instead of localhost I will be using the host IP of course. The db my1DB is actually created and already contains a relation named countries.
I have Yii2 basic installed on my client. Now my question is, do I need to install it on the server as well? It may be a dumb question and I am truly sorry if it is, but I am not sure if I am understanding it all correctly. So, does the db.php file need to be on the server? Or is it OK if it is simply installed on my client?
The db.php would need to be on server side where the PHP is running at, in case the PostgreSQL server is running on the same server that PHP is, you can leave it as localhost and it should work fine, just make sure the credentials and db name exist.
I follow this tutorial to create my user online list.
In my local MAMP server on Mac OSX it work fine, but if I tried to put in Ubuntu server, I got this error (at the index, without logged in):
Fatal error: Uncaught exception 'CDbException' with message 'CDbCommand failed to execute the SQL statement: SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'session' already exists.
I can catch the exception but I would to know because in OSX it works fine but in Ubuntu it's not works.
I think it may be something in Apache or other config: is it possible ?
Is session created before login ? The component need a user_id (not null) in the session table so I think there is anything I don't understand.
In both php.ini I set session.auto_start = 0.
Probably the problem is that in those 2 servers you have slight differences, and among them the table 'session' which is already available in the Ubuntu server, and is probably handled for a total different reason against what you need, while in your MAC env there is no such thing as 'session' table.
The easy and clean way I can think of to solve the collision of names is to rename your table name from 'session' to 'mysession' changing the config setting this way:
'session' => array (
'class' => 'application.components.DbHttpSession',
'connectionID' => 'db',
'sessionTableName' => 'mysession',
'userTableName' => 'user'
),
And update every occurrence of the table name (like in queries) in your code.
This way the collision should be gone and everything should work fine.
I hope it helps.
This is what I did:
I downloaded the yii2 advanced template.
Ran php init.
Configured each of main-local.php files in
environments/dev/common/config
environments/prod/common/config
common/config
I added the following to the 'components'
'db' => [
'class' => 'yii\db\Connection',
'dsn' => 'sqlite:/path/to/sqlitedbs/yayr.sq3',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
],
I configured the apache vhosts as explained in the readme.
Running yii migrate created the sqlite database file in the configured location with no errors.
What breaks is when I go to the frontend app and try to submit the sign up form, it gives me this error:
Exception
Database Exception – yii\db\Exception
SQLSTATE[28000] [1045] Access denied for user 'root'#'localhost' (using password: NO)
↵
Caused by: PDOException
SQLSTATE[28000] [1045] Access denied for user 'root'#'localhost' (using password: NO)
in /home/johnsmith/dev/test/yayr/vendor/yiisoft/yii2/db/Connection.php at line 579
The full stack trace can be seen: http://pastebin.com/KEKH1zbM
I have used my IDE to search for every location that a mysql dsn exists. The only place is in /tests/codeception/config/config.php which should not be called by submitting a form. To double check, I commented out the config, and it didn't help.
I also tried setting 'driverName' => 'sqlite', in the config, but that did not make any difference. Neither did commenting out the username, password, or charset parameters.
None of the functions referenced by the stack trace appear to manually call MySQL. They all look for the configured dsn.
So, why does Yii think it can even try to connect to MySQL? Doesn't ActiveRecord abstract out all the SQL so that it won't matter if I'm using MySQL or sqlite?
How do I get past this issue? Using sqlite would make initial development a lot easier.
Thanks!
Basics of the Yii2 advanced template
You have the environments-folder containing you actual config files
The frontend- and backend-folders hold copies of those "local"-files, depending on which environment you selected, they get copied from dev or prod
Now what does that mean? If you perform changes on ANY file within the envirnments folder, you have to re-init your application. You simply do this by opening a console, navigate to the base folder of your application and call the init-command. You will then be asked which envirnment you want and what files to overwrite.
After that you should see your changes beeing reflected in the frontend- and backend-folder. The idea behind this is to prevent if/else-structures within the config files and have a clean application. By the way: the index.php within the web-folders gets copied the same way. That way you could even customize this...and therefore the way the application gets loaded initially.
Back to your problem
For me it looks like you changed the settings within the environments/.../local-...-configfile, which is right...but then didn't re-init the application. That way the config file within the front- and backend still contain your old settings.
Documantation of the advanced template
Everything is very well documented here:
https://github.com/yiisoft/yii2-app-advanced/blob/master/docs/guide/README.md
After init command
Create a new database and add it in common/config/main-local.php
'components' => [
'db' => [
'class' => 'yii\db\Connection',
'dsn' => 'mysql:host=localhost;dbname=your-db',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
],
Apply yii migrate in console command!
It'll create the tables for the application to work
I am using Laravel to connect to MySQL database and got this exception:
PDOException
SQLSTATE[HY000] [1049] Unknown database 'forge'
and this is my config.database.php
'mysql' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'laravel',
'username' => 'Anastasie',
'password' => 'A#Laurent',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
why is the error referring to PDO database? and why the forge database name? I have already changed it.
Should I do anything to tell Laravel that I am using MySQL database?
Update 1
I found this line
`protected $table = 'users';`
in my user.php file and I have changed it to
`protected $table = 'user';` because the table in my database is `user` not `users`
Update 2
I wrote this in my Route
Route::resource('users', 'UsersController');
and I added UsersController.php in my controllers folder
and inside UsersController.php I have this:
class UsersController extends BaseController {
/**
* Display a listing of the resource.
*
* #return Response
*/
public function index()
{
$users = User::all();
return View::make('users.index', compact('users'));
}
and I call this url http://localhost:8082/laravel/public/users/
I am using Windows 7 with Laravel 4.2
You have to clear the cache like that (because your old configuration is in you cache file) :
php artisan cache:clear
The pdo error comes from the fact Laravel use the pdo driver to connect to mysql
First you have to Create your related Database.
Then:php artisan cache:clear
Now run php artisan migrate:install
Hope your problem will get resolved.
Using phpMyAdmin (or whatever you prefer), I just created a database called "forge" and re-ran the php artisan migrate command and it all worked.
write
php artisan config:cache
in your terminal and it will be fixed
Sounds like you have an environment-specific config file somewhere that overrides the default database settings. Possibly app/config/local/database.php.
Note: Once it happened that I accidentally had a space before my database name such as mydatabase instead of mydatabase, phpmyadmin won't show the space, but if you run it from the command line interface of mysql, such as mysql -u the_user -p then show databases, you'll be able to see the space.
I had the same problem...
If you have set your DB name and username and pass correctly in .env file and its still not working run the blow code in terminal:(this will clean the caches that left from previous apps)
php artisan cache:clear
and then run the command php artisan serve again (if you are running it stop and run it again)
Stop the server then run php artisan cache:clear.
Start the server and should work now
Stop the server then run php artisan cache:clear.
Change .env file DB_PORT=3308 (3308 For me)
mysql port
I did all of them but didn't work, I find out should stop php artisan serve(Ctrl + C) and start php artisan serve again.
If you've used Homestead, make sure the database name in your .env file below
DB_DATABASE=homestead
Is the same as the value in your Homestead.yaml file.
databases:
- homestead
first clear your cache using this command
php artisan cache:clear
Then restart the server using this command
php artisan serve
In my case the error was due to incorrect port number (the error is definitely due to incorrect credentials i.e. host/port/dbname/username/password).
Solution:
right click on WAMP tray;
click (drag your cursor) on MySQL;
see the port number used by MySQL;
add same in your Laravel configuration:
.env file;
config/database.php.
Clear cache
php artisan config:cache
Run migration
php artisan migrate
Check your port in WAMP (it places on top of the phpMyAdmin) match with DB_port in the .env file.
My DB_port in .env is 3306. My server port in WAMP (phpMyAdmin) is 3308 - you should match them.
you need just create database or import your data by localhost phpMyAdmin and don't forget the name should be same named
Encountered this issue quite a few times, note that I'm running laravel via Vagrant. So here are the fixes that work for me:
Try again several times (refresh page)
Reload vagrant (vagrant reload)
You may try reloading your server instead of vagrant (ie MAMP)
OK, found solution.
In the file database.php, by default, it comes the "mysql" part:
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
all you need to do is change the values :
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
by your database name (you must create one if you dont have any) and by that database username
like this
'database' => env('DB_DATABASE', 'MyDatabase'),
'username' => env('DB_USERNAME', 'MyUsername'),
Make sure you do not have a duplicated .env file in the laravel folder. If it exists, delete it. Only keep the .env file.
You need to modify the name of the DB in the file .env (and if need in .env.example)
I solved my problem with this little correction.
In my particular case, I finally realised that my phpMyAdmin was using port 3308 while Laravel was attempting to connect through 3306. so my advice would be to ensure you have the correct connection string!
Here is my response to the problem described in the question.
in cmd write:
php artisan cache:clear
then try to do this code in your terminal
php artisan serve
note:
this will start again the server
I had this problem for several days, it turns out if I created the db inside phpMyAdmin it wouldn't appear to Laravel,
so, I created the db through MySqlWorkbench, and it worked :)
clear your Cache php artisan cache:clear and then restart your server php artisan serve 127.0.0.1:8000
My APP_NAME variables in .env.example and .env and app.php were with space e.g. The App . Surounding that by ' and php artisan cache:clear and setting new generated app key to APP_KEY variable through env files and relaunching the server by php artisan serve solved this issue
In the fourth solution this question was answered but I prefer to answer again to explain this differently .
I make my database in phpmyadmin that is http://localhost/phpmyadmin and the problem was solved .this is my code :
<?php
$servername = "127.0.0.1";
$username = "root";
$password = "";
$dbname = "myDbn2";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "Database created successfully<br>";
$sql = 'create table if not exists fruits (id integer , name text , color text
, price float) ;';
$conn->exec($sql);
echo 'the table created successfully </br>';
$sql2 = 'insert into fruits values (1 , "apple", "red" , 23.2);';
$conn->exec($sql2);
echo 'insert was successfully';
} catch (PDOException $e) {
echo $e->getMessage();
}
$conn = null;
?>
The code make a database then make a table and insert a record in it .
if you don't make your data base in phpmyadmin site you get the exception
also you don't need to use sql statement CREATE DATABASE name ; and it works without it .
php artisan config:cache
that command fix my 1049 database not found.
Every body have mentioned to php artisan cache:clear. Sometimes it doesn't work.
But in my experience after clearing the cache simply delete the database and create it again.Then run this again
php artisan migrate
Surely it will work.
I got this error because MySQL could not access the database configured in the environment file.
To resolve, I simply created the database that MySQL and the app needs and all works fine.
in my experience I had like this message error ,and i tray all of this solution but nothing to become good ,whay because my fault is i unstall Xampp and i read install again and i forget to create new Database with table that's way in the message say : "Unknown database" it's not exist simply ,now what i do is:
install Xampp (if you have problem in it ofcaurse)
i create now database + table
short you don't see the error message again .
NB ( I'm new in Programation )

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 error:
Cake is NOT able to connect to the database. Database connection
"Mysql" is missing, or could not be created.
When I run this helpful code in my home.ctp, I get the following response:
Error!: SQLSTATE[42000] [1049] Unknown database 'test'
However, my Users/Ben/Sites/myapp/app/Config/database.php looks like this (I set MAMP to look for the document root in Users/Ben/Sites):
<?php
class DATABASE_CONFIG {
public $default = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => 'Ben',
'password' => 'mypass',
'database' => 'CV',
);
}
I have created a mysql user called Ben with password mypass and created a database called CV under that. Moreover, I can't find mention of a test database anywhere. Help?
Try adding the socket:
'unix_socket' => '/Applications/MAMP/tmp/mysql/mysql.sock',
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',
);
Edit php.ini and add:
extension=php_pdo_mysql.dll
Then restart your web server
On Mac, using MAMP as a development platform, for cake the correct solution is using Domingo Casarrubio solution.
Add the unix_socket parameter to your database configurations.
'unix_socket' => '/Applications/MAMP/tmp/mysql/mysql.sock',
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.
I noticed that you've had asked this an year ago, and most probably would've solved this by now. However, for those facing the same issues when attempting to install CakePHP on XAMPP, all you have to do is change the 'login' to 'root', i.e. the default login of XAMPP, and leave the 'password' as '', i.e. blank. The complete code in your database.php file should look like this:
public $default = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => 'root',
'password' => '',
'database' => 'ckblog',//replace with your own database name
'prefix' => '',
//'encoding' => 'utf8',
);
That's it.
I had the same problem and found out eventually that it was caused by CakePhp not accepting that I used a user with a password, even if that user was created in PHPMyAdmin. I had to use the user 'root' with no password.
I found this out after making the following change to the file /lib/Cake/Error/exceptions.php.
The original line:
protected $_messageTemplate = 'Database connection "%s" is missing, or could not be created.';
is changed into this instead (note the change from single to double quotes):
protected $_messageTemplate = "Database connection \"%s\" is missing, or could not be created:\n %s";
This will give you the reason for the problem so that you may change the cause properly.
I have had this problem since upgrading to OSX Yosemite and inserting following line did the trick for me:
'unix_socket' => '/tmp/mysql.sock'
It can be that mysql PDO support is missing.
as root (or using sudo):
apt-get install php5-mysql
Just to help Ubuntu users out:
I had the same error in my ubuntu 13.10 machine with the newest xampp downlaoded directly from apachefriends. Tried most of the stuff in every post I could find about this error, but not the mac-specific stuff.
In the end, the fix happened to be the same as the elected answer here:
Find the socket that mysqld creates for programs to connect to:
user#host /opt$ 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.".
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!
What did it for me in the end was that I had created a table in my database, but there was no data in it.
In order for CakePHP to recognize the MySql connection, there has to be a table with data in it.
You might need to create the table in your php file... Open up phpMyAdmin and check to ensure that they database CV exists.
It's your model. Open that up and there must be the following line
public $useDbConfig = 'local';
This overwrites global config & set it back to local
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
In my case it was because the database didn't exist. I expected running ./app/Console/cake schema create would create it but it did not. Creating it with create database <database name> in mysql did the trick (although I had already assigned privileges).
I've been struggling with this the whole weekend and finally solved it. Turns out that the php.ini is pointing to a non-existing "extensions dir". Create a phpinfo() file and look at the value of this field:
I noticed that in the mamp php installed folder there is a no-debug-non-zts-20131226 folder, which is different from the value shown in the phpinfo(). What I did was to clone this folder and changed the name to the value of the phpinfo(). Probably you could modify the php.ini file but I didn't want to.
I don't know if you solved your problem, but I'm posting this because my problem was different and google took me here, so I hope to help future googlers having a similiar issue.
Hope this helps.
