MariaDB deny default root@localhost FIX / Allow all IPs / Recreate user
Can login as root using mysql -u root but not from PHP on the same host
First, login to MySQL
sudo mysql -u rootCheck your accounts present in your db
SELECT User,Host FROM mysql.user;
+------------------+-----------+
| User | Host |
+------------------+-----------+
| admin | localhost |
| debian-sys-maint | localhost |
| root | localhost |
+------------------+-----------+Delete current 'root'@'localhost' account
DROP USER 'root'@'localhost';
Query OK, 0 rows affected (0,00 sec)Recreate your user
CREATE USER 'root'@'localhost' IDENTIFIED BY '';
Query OK, 0 rows affected (0,00 sec)Add password for better security using IDENTIFIED BY 'Passw0rd' instead of IDENTIFIED BY ''
Give permissions to your user (don't forget to flush privileges)
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION;
Query OK, 0 rows affected (0,00 sec)
FLUSH PRIVILEGES;
Query OK, 0 rows affected (0,01 sec)quit for exit
'root'@'%' instead of 'root'@'localhost' for access from everywhere. VERY DANGEROUS
If you want the server to be accessible from everywhere you'll need to comment bind-address = 127.0.0.1 from /etc/mysql/mariadb.conf.d/50-server.cnf using a # or set it to 0.0.0.0. remember to restart the service to apply the config
