php – SQLSTATE[HY000] [2002] Connection refused within Laravel homestead

Posted by: admin April 23, 2020 Leave a comment

Questions:

Using Mac OS X and Homestead 2.2.1 with Laravel 5.2.

In terminal (within homestead in my project folder) I can do php artisan to see all the available commands. When I try to run php artisan migrate I get a connection error:
SQLSTATE[HY000] [2002] Connection refused


I have setup a Laravel project with these .env settings

DB_HOST=127.0.0.1
DB_DATABASE=tcv
DB_USERNAME=homestead
DB_PASSWORD=secret

I have also tried localhost for DB_HOST and root for DB_USERNAME and DB_PASSWORD. And all possible variations of these put together!


In Sequel Pro (db management application) I CAN connect with these settings

Host       127.0.0.1
Username   homestead
Password   secret
Database   tcv
Port       33060

But this database is obviously empty, because I cant migrate to it from terminal …

As far as I can make out it is a configuration issue, since I can connect to it with Sequel Pro. But I have honestly no freaking idea what is setup wrong.

Thanks for the help !!

EDIT
For some reason I get the same SQLSTATE[HY000] [2002] Connection refused error when moving my project to MAMP and running php artisan migrate.
Now I am completely lost …

How to&Answers:

I just ran into this and found that changing this in the .env file from 127.0.0.1 to localhost fixed it.

DB_HOST=localhost

Answer:

Problem

In Laravel you have config/database.php where all the setup for the connection is located. You also have a .env file in the root directory in your project (which everyone uses for timesaving). This contains variables that you can use for the entire project.

On a standard L5 project the MySql section of config/database.php looks like this:

    'mysql' => [
        'driver'    => 'mysql',
        'host'      => env('DB_HOST', 'localhost'),
        'database'  => env('DB_DATABASE', 'forge'),
        'username'  => env('DB_USERNAME', 'forge'),
        'password'  => env('DB_PASSWORD', ''),
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
        'strict'    => false,
        'engine'    => null,
    ],

Notice there is no port set!

Although in my .env file I had set DB_PORT=33060. But that value (3306) was never read into the config/database.php.
So don’t be a dumbass like myself and forget to check the database.php file.


FIX
Simply add 'port' => env('DB_PORT', 3306), to your config/database.php and set that value in .env like this DB_PORT=3306

Answer:

If you are using MAMP on a mac OS add the following line to your mysql database config file

'unix_socket' => env('DB_SOCKET', ''),

and on your .env file add

DB_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock

Answer:

Use localhost instead of 127.0.0.1 (in your .env file), then run command:

php artisan config:cache

Answer:

Another solution for anyone else who has a problem. I had all the settings correct but for some reason my changes weren’t updated. Laravel actually caches the config file (which I find completely stupid).

Here was my solution after updating the configs:

php artisan config:clear

Answer:

I was having this problem. When connecting with Sequel Pro, I need to use 33060 as the port, but in the .env file it has to be 3306. I had 33060 in the .env file. Changed it to 3306 and it worked.

Answer:

I had the same problem and fixed just by converting DB_HOST constant in the .env File FROM 127.0.0.1 into localhost DB_HOST = localhost.

No need to change anything into config/database.php

enter image description here

Answer:

I had the same problem, try this works

DB_HOST=localhost

Answer:

This is a simple fix. Your mysql database has lost its connection to the server. If you are running a local server run this in your terminal:

mysqld

That will reconnect your database. Then (if you are using homebrew) run:

brew services start mysql

This will automatically connect your database on login.

Answer:

In my case this error appeared out of blue. While staring at that mysterious error I’ve realized, that I was trying to run the command outside of vm…

Answer:

It’s possible that your mysql hasn’t started or is not to the port 3306

Answer:

After you put all configuration on .env file, if you already run php artisan serve, RESTART IT.

Answer:

In my case, I was having the same error using docker and the trick was in setting in the .env file this DB_HOST=db where db is the name of the container running the database server.

Answer:

When Laravel connects to mysql on Homestad box and running commands on local environment:

DB_HOST=127.0.0.1
the app needs DB_PORT=3306
the migrations need DB_PORT=33060 otherwise gives Connection refused
phpunit needs DB_PORT=33060 otherwise gives Connection refused

DB_HOST=localhost
the app works with both DB_PORT=3306 or DB_PORT=33060
migrations cannot run
phpunit cannot run

Have in mind that phpunit takes its values from the .env.testing file, if exists, otherwise from the phpunit.xml file on the root folder of the app

Answer:

Me, Im using vagrant, yet im executing php artisan outside the box so basically it doesn’t have permission

Answer:

For me enclosing the credentials in quotes did the trick

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE='zzz'
DB_USERNAME='yyy'
DB_PASSWORD='XXX'

Answer:

If you are using Homestead then you should be running it with the default mysql port. So instead of using DB_PORT=33060, you should be using DB_PORT=3306 in your .env file. Also, remember to run your php artisan migrate commands in your homestead installation and everything should be ok.

Hope that helps.

Answer:

The only thing that solved it for me was to put the connection details in config/database.php instead of the .env file. Hope this helps

Answer:

I had a similar problem and no suggestions placed here helped me.
This what has fixed my problem was to set the application name and database hostname with the same value. In my case, 127.0.0.1 works correctly.

APP_URL=127.0.0.1

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=zzz
DB_USERNAME=yyy
DB_PASSWORD=XXX

Answer:

Okay update it seems the host is not the issue but actually the port.

So its actually the port 3306 for the browser testing and yet for terminal and Sequel Pro 33060. Could it have something to do with adding it in the Homestead.yaml and set it here?

On reading the setup in relation to Laravel it says:

MySQL: 33060 → Forwards To 3306

Answer:

I could be because you might have not restarted PHP artisan since long

So After making DB changes and config:clear Tinker works fine

But to make browser refect the new DB connection you need to re-run

php artisan serve

Answer:

  1. terminate sqld from task manager
  2. stop MySQL from xampp control panel and restart it

if it still throw the same problem, from root folder run

php artisan cache:clear
php artisan config:cache
php artisan serve
  1. if you still have the problem, check whether you are using multiple copies of sql server, for example through Ubuntu app, if so stop the MySQL server in ubuntu

    sudo service MySQL stop

Answer:

DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=8080
DB_DATABASE=flap_safety
DB_USERNAME=root
DB_PASSWORD=mysql

the above given is my .env

    'mysql' => [
        'driver' => 'mysql',
        'url' => env('DATABASE_URL'),
        'host' => env('DB_HOST', 'mysql'),
       // 'port' => env('DB_PORT', '8080'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', 'mysql'),
        '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'),
        ]) : [],
    ],

the above given is my database.php file. i just commented out port from database.php and it worked for me.

Answer:

I found that my server just needed to be restarted and “bam” it was fixed.

Answer:

I encountered

SQLSTATE[HY000] [2002] Connection refused (SQL: select * from
projects)

The cause was that I had not started the MySQL server.

It may help to check that the MySQL is running as the first step in troubleshooting the error.
