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

最佳答案

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

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.

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.

小开

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

小开

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

小开

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...

小开

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

小开

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.

I had the same problem, try this works

DB_HOST=localhost

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

小开

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

php artisan config:cache

小开

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

小开

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

小开

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

小开

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

小开

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

小开

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

小开

terminate sqld from task manager
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

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

小开

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'

小开

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.

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.

PROBLEM SOLVED

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

JUST DO THIS AS GIVEN IN THE BELOW LINE

DB_HOST = localhost.

No need to change anything into config/database.php

Don't forget to run

php artisan config:clear

小开

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

小开

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.

小开

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

小开

If you are using Homestead like I do, do not forget to ssh into it before running artisan test for example.

小开

If you have your backend and database started on docker

Instead of putting localhost or 127.0.0.1 as DB_HOST put the name of the registered service that indicates your database service in the docker-compose file.

In my case for example I replaced 127.0.0.1 with db because in my docker-compose file I had defined the name of the service for the database as db

My docker-compose looks something like that

services:
db: <------ This is the name of the DB_HOST
container_name: admin_db
image:mysql:5.7.22
.
.
.

I don't think it even reads config/database.php. As soon as edited my entries into .env file it started working.

If you have any kind of proxy or vpn , turn them off and close them . it was my problem .

On ubuntu/linux you can try to restart mysql with this command: sudo service mysql restart

In case this helps someone in the future... I have to run artisan commands and so on using WSL but MySQL lives on my Windows environment. I struggle with the correct terminology but my brain says "I don't care if you think you're a virtual machine, you're quite literal and literally right in front of me so when I say connect to yourself I expect you to do so."

If I understand correctly, PHP is executing the commands in magical WSL-land so it needs the IP of the database in relation to WSL-land.

From a command prompt (Windows, not in WSL) I ran ipconfig to find my IPv4 and put that for my Laravel DB_HOST. Now, when I migrate in WSL it works.

I realize this was overly wordy but I personally get very confused with all of the virtual machine stuff, so I put the answer I wish I'd found weeks ago.

Wish I'd never gone back to Windows.
