Laravel Can't Connect to database - Migrations - Error 2002 - mysql

Question

I have searched for a couple of hours now, and still am unable to find this.
I get 2 errors, if I use the database host as 'localhost', I get this error:
[PDOException]
SQLSTATE[HY000] [2002] No such file or directory
and if I change the database host to '127.0.0.1' I get this error:
[PDOException]
SQLSTATE[HY000] [2002] Connection refused
Things I have tried:
changing where the apache / mysql server is run (either user or `josh (Apache) / josh (MySQL)
changing the port that MySQL runs on in MAMP, and putting that port in the mysql array in the database.php file
changing the host of the connection from localhost to 127.0.0.1 and back.
creating a new user in phpmyadmin
turning off the firewall
Any ideas how to fix this?

Answer 1

I figured it out, add this after the 'host' => '127.0.0.1':
'unix_socket' => '/Applications/MAMP/tmp/mysql/mysql.sock'
So the connection would look like this:
'mysql' => array(
'driver' => 'mysql',
'host' => '127.0.0.1',
'unix_socket' => '/Applications/MAMP/tmp/mysql/mysql.sock',
'database' => 'dbname',
'username' => 'josh',
'password' => 'pass',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
)

Answer 2

fist clear your config file by typing
php artisan config:clear
Then modify your .env file
APP_URL = 127.0.0.1
DB_HOST = 127.0.0.1
Hope this works for you.

IF you use lampp . You can try this:
Open file mysql config. (you can open lampp control panel in /opt/lampp/manager-linux-x64.run,after that open Configure of Mysql Database or open /opt/lampp/etc/my.cnf).
Find and see "socket =/opt/lampp/var/mysql/mysql.sock",
Add 'unix_socket' => '/opt/lampp/var/mysql/mysql.sock' to file database.php in laravel:
'mysql' => [
'driver' => 'mysql',
'unix_socket' => '/opt/lampp/var/mysql/mysql.sock',
'host' => env('DB_HOST', 'localhost'),
'database' => env('DB_DATABASE', 'luanvan'),
'username' => env('DB_USERNAME', 'huuthang'),
'password' => env('DB_PASSWORD', '123456'),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
File mysql.sock depend on your install location of lampp. I let you see if you can't find it. Good luck

Answer 4

I had to do the following in ubuntu 15.10
copy the file or file contents from /opt/lampp/etc/my.cnf to /etc/mysql/my.cnf
Then open database.php file in your app/config folder and add the following line below 'host' => env('DB_HOST', 'localhost')
'unix_socket' => '/opt/lampp/var/mysql/mysql.sock'
That solved my problem, could save someone else's. Please note that it is VERY IMPORTANT you first verify the directory which contains mysql.sock file before configuring the path.
