While creating site , asked for password mysql . after that i got error

are sure you enter the password correctly?

I have not entered any password before !!!

just creating site, I entered password like 123.

be sure via enter db first by this command and check if it success or not

mysql -u root -p

and check if it’s active

systemctl status mariadb

While setup mariadb and mysql, you set your mysql root password. Enter that password while creating site
