I updated my Linux 14.04 LTS to 18.04 and had to downgrade the PHP 7.2 to 7.0 as I need to run some software which is not capable of the preinstalled PHP 7.2. I used PHP 5 so far.
After I got everything runnning now, MySQL, Apache and PHP I created a new database and now I get a Notification that the control user can't be connected and that 'pmp'@localhost has denied access.
This appears when I log into server @ localhost.
If I choose localhost:3306 everything works fine. But I do not know why I have two server logins?
I'm somehow confused, that I get two servers to choose from (localhost and localhost:3066) which I would not have expected. Can I somehow delete the localhost-access for PHPmyAdmin and only enable localhost:3306?
Any idea what I have to do? I'm a database newbie. Best
There are two ways to connect to the mysql on the localhost. One is the connection via network @localhost:3306 and another is the connection through the filesocket like /tmp/mysql.sock. Filesocket connection is preferred due to the lower overhead and mysql library choose it if available when connection to the localhost requested. I have no clue why they are separated now.
mysql
@localhost:3306
/tmp/mysql.sock
If you want to connect to the mysql only locally then networking can be disabled completely in the my.cnf so all connections are forced to be filesocket-based. That is also a bit more secure as far as no one can connect to the mysql over the network.
my.cnf
