Symfony 5 : SQLSTATE[HY000] [2002] refusing connection - mysql

Question

I aam trying to create a new doctrine database using Symfony 5.
Recently Symfony changed using mysql by default to using pstgreSQL.
As I want to use mysql I changed the comment in .env from :
# DATABASE_URL="mysql://db_user:db_password#127.0.0.1:3306/db_name?serverVersion=5.7"
DATABASE_URL="postgresql://db_user:db_password#127.0.0.1:5432/db_name?serverVersion=13&charset=utf8"
to
# DATABASE_URL="mysql://root:#127.0.0.1:3306/mywebsite?serverVersion=5.7"
DATABASE_URL="mysql://root:d#127.0.0.1:5432/mywebsite?serverVersion=13&charset=utf8"
in other words I just changed postgresql to mysql and commented what needs to be commented.
However when I run
php bin/console doctrine:database:create
I get the following error :
In AbstractMySQLDriver.php line 112:
An exception occurred in driver: SQLSTATE[HY000] [2002] No connection
has been established as the target computer rejected it (translated
from french)
I found the following posts :
An exception occurred in driver: SQLSTATE[HY000] [2002] Connection refused
and
In AbstractMySQLDriver.php line 112:
An exception occurred in driver: SQLSTATE[HY000] [2002] php_network_getaddr
esses: getaddrinfo failed: Hte inconnu.
in short both tells me to change "127.0.0.1" by "mysql"
but when running as such I get this error
In AbstractMySQLDriver.php line 112:
An exception occurred in driver: SQLSTATE[HY000] [2002]
php_network_getaddr esses: getaddrinfo failed: Hte inconnu.
What mistake did I do or what did I miss?
Thank you

Answer 1

I found a very simple solutionthat will seems obvious for experienced dev but not for beginners that is never talked about.
just change the # at the beginning of the first line
# DATABASE_URL="mysql://root:#127.0.0.1:3306/mywebsite?serverVersion=5.7"
DATABASE_URL="mysql://root:d#127.0.0.1:5432/mywebsite?serverVersion=13&charset=utf8"
to the second line
DATABASE_URL="mysql://root:#127.0.0.1:3306/mywebsite?serverVersion=5.7"
# DATABASE_URL="mysql://root:d#127.0.0.1:5432/mywebsite?serverVersion=13&charset=utf8"

You can found documentation here https://www.doctrine-project.org/projects/doctrine1/en/latest/manual/introduction-to-connections.html
In your config the port 5432 is not default port of Mysql
Try
DATABASE_URL="mysql://root:d#127.0.0.1:3306/mywebsite?serverVersion=13&charset=utf8"
