So first thing first i've created migration tables and it successfully migrated and seeded. i've change the .env file
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=jj
DB_USERNAME=root
DB_PASSWORD=
i've tried to change the database.php
'mysql' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'jj'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
but i'm still unable to login. the error says SQLSTATE[HY000] [1049] Unknown database 'laravel' (SQL: select * from `users` where `username` = admin limit 1) even though i've migrated and seeded the database
If the configuration looks okay and you are 100% certain that MySQL is running, you might want to clear the configs and caches.
php artisan config:clear
php artisan cache:clear
Try the config one and then the cache if the problem isn't resolved by the first command.
You can read more about the commands here

I am trying to connect laravel application to php myadmin.
When DB_HOST=127.0.0.1 in my .env file
SQLSTATE[HY000] [2002] Connection refused (SQL: select * from `sessions` where `id` = EO901DpTx4qUrgxMniyykEu84HrJGQESns0ySzlx limit 1)

changing the DB_HOST to localhost and 127.0.0.1 (most common
answer online, no succes)
making sure SQL is running

I want to create a second database to act as a backup. I've been following another SO question solution and other websites which leads to the same thing. I've added a new DB connection in .env and configured it in database.php, cleared out the cache using php artisan config:cache. When I try to migrate using php artisan migrate --database=backup_literature_review_management, it says InvalidArgumentException, Database connection [backup_literature_review_management] not configured.
.env

Cleared cache before migrating
php artisan config:cache
Trying to migrate to 2nd DB
php artisan migrate --database="backup_literature_review_management"
Error
InvalidArgumentException, Database connection [backup_literature_review_management] not configured.
You are calling the wrong connection. Use this:
php artisan migrate --database="mysql2"
You can also define the connection inside the migration file like:
Schema::connection('mysql2')->create('table', function (Blueprint $table) {...
With this last command, you can ommit --database="mysql2 in the migration command. I personally prefer to declare the connection inside the migration file.
Hope it helped!
I'm trying to publish my Laravel 5.8 app on production hosting. I've uploaded the files and have made the changes in .env file. But still while accessing my application., it throws error:
Access denied for user 'root'#'127.0.0.1' (using password: NO)
Below is my .env file:
DB_CONNECTION=mysql
DB_HOST= ip
DB_PORT=3306
DB_DATABASE=secret
DB_USERNAME='secret'
DB_PASSWORD='secret'
I have also made changes in database.php:
'users' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', 'secret'),
'port' => env('DB_PORT', '3306'),
'database' => env(‘DB_DATABASE', 'secret'),
'username' => env('DB_USERNAME', 'secret'),
'password' => env('DB_PASSNORD', 'secret'),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO: :I'IYSQL_ATTR_SSL_CA => env( 'MYSQL_ATTR_SS L_CA' ),
]) : [],
},
Try.
php artisan config:cache
then
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=secret //enter your right databse name
DB_USERNAME=secret //please check your username
DB_PASSWORD=secret //please check your password
or
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=secret //enter your right databse name
DB_USERNAME=root //please check your username
DB_PASSWORD=enter your correct password //please check your password
change your databse.php
'users' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'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_PASSNORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => false,
'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO: :I'IYSQL_ATTR_SSL_CA => env( 'MYSQL_ATTR_SS L_CA' ),
]) : [],
},
As a comment suggest, use localhost instead of 127.0.0.1, but also, same error occurs to me and the problem was the Laravel project cache: just use php artisan config:cache to re-cache the files, or just delete all the files inside the bootstrap/cache folder
How to change database name in Laravel?
I already made changes in config/database.php and .env file. I need database name as scoolmgmt
Config/database.php
'mysql' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'scoolmgmt'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
**Routes.php**
Route::get('/dbname', function(){
return DB::getDatabaseName();
});
Output is:- laravel
Caching stores the configured values from the config files.
You can clear the Cache with the following artisan command php artisan config:clear
After your change you can make a new cache file with the command php artisan config:cache
type in project terminal
php artisan config:cache
Your database will definitely get updated
