APP_ENV=local
APP_KEY=my app key
APP_DEBUG=true
APP_LOG_LEVEL=debug
APP_URL=http://localhost

DB_CONNECTION=mysql
DB_HOST=my ip
DB_PORT=3306
DB_DATABASE=form
DB_USERNAME=root
DB_PASSWORD=my pass

Answer 1

在.env文件中，将DB_HOST从127.0.0.1更改为localhost

Answer 2

Put string:

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

after DB_PASSWORD=

It works for MAMP. Set your path to mysql.sock

Answer 3

There are a few possibilities why your getting this error.

• database server isn't started, check if you can still use your phpmyadmin. If you can still use it then nothing is wrong with your database server.
• wrong config; check username, password and server settings in both your .env file and your config/database.php
• no privileges to the server and or database with given credentials Looking at the steps you already took I think it's the last.

Check to see if this user has access to the database from the remote location. By default the root user has access to the server locally (localhost,127.0.0.1 and ::1).

So check to see if the user has access from either your remote ip or from anywhere.

As you are using digitalocean I would suggest to check if they have a specific configuration to connect to mysql database.

Answer 4

In your .env file, change DB_HOST from 127.0.0.1 to localhost

and then

1. php artisan cache:clear
2. php artisan route:clear
3. php artisan config:clear

4. php artisan view:clear

   This worked for me.

Answer 5

SELinux might be the cause.

Set this rule and try again:

sudo setsebool -P httpd_can_network_connect_db=1

Answer 6

After long hours this worked for me:

Changing the port in php My Admin previously 8889

APP_NAME=laravel
APP_ENV=local
APP_KEY= YOUR KEY
APP_DEBUG=true
APP_URL=127.0.0.1

LOG_CHANNEL=stack

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock

and then

php artisan cache:clear
php artisan route:clear
php artisan config:clear
php artisan view:clear

Answer 7

My composer was installed globally, i run php artisan serve without starting xampp & getting this error. After running my xampp server, it's working fine from my side.

Answer 8

In attempt to provide a solution for those of you that have not found success in any of the already mentioned answers, I will share my solution.

Coming from Windows 10 I was of the understanding that the password for the root user was always blank thus my .env file looked as follows:

DB_USERNAME=root
DB_PASSWORD=

On Mac, the password is defaulted to "root" also. Changing my .env file to look as follows fixed my issue:

DB_USERNAME=root
DB_PASSWORD=root

Answer 9

in your .env file

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=ur_db_name
DB_USERNAME=ur_db_username
DB_PASSWORD=ur_dbuser_password

Answer 10

Before you do changes as per instructed above,

1. check if your database server running or not. If you are using command prompt , running mysql.server status or mysqld status shall show the database status.
2. If the database is running, check if the dbuser is allow to connect from '%' or 'localhost' or '127.0.0.1' . If not, just grant the user access from '%'
3. If you have done 1 and 2 and still can't connect, see if the db user is allow to access the schema. If not, grant access to the schema
4. If you reach here and still got the same error, try to restart you web server.

Answer 11

If you are using XAMPP on Mac, Just use the embedded Ip Address from your XAMPP Dashboard as DB_HOST instead of 127.0.0.1 or localhost...
