Error #1251 - Cannot log in to the MySQL server

[seth5728]

I bought a VPS today to use as my new MySQL server. I installed MySQL, Apache, PHP, and phpMyAdmin. I set up my MySQL user as "admin". I am able to log into the user on the command-line, but not in phpMyAdmin. I get the error #1251 Cannot log in to the MySQL server.

The issue is on a new Linux VPS running CentOS 6, MySQL 8.0.16, and Apache 2.2.15. I have tried everything I came across in the past 6 hours of googling. I will create a list of everything I've tried since that will be easier to read.

• - setting bind-address to 127.0.0.1
  - putting my username and password into config.inc.php
  - setting the host to 127.0.0.1 in config.inc.php
  - trying sockets over TCP (and setting the host to localhost when using sockets)
  - creating a soft-link shortcut from `/usr/share/phpmyadmin` to `/var/www/html/phpmyadmin`
  - reinstalling and running mysql_secure_installation

and a lot more things that I can't quite recall at the moment.

After trying all of this, I have had no luck and I am still getting the same error #1251 Cannot log in to the MySQL server. Any help would be greatly appreciated at this point, as I am getting desperate.

I'd suggest trying to login as that user from the commandline as in:

mysql -u <username> -p<password> -h 127.0.0.1
NOTE: No space between -p and the password.

MySQL may differ between (say) a user logging in as <user>@127.0.0.1 and <user>@localhost for example.
If you can login as that user to MySQL, and you are really using the configuration parameters you've set in the PHP side of things, then the problem probably exists in the PHP/Apache side of things.
That's gotta be a better start than randomly throwing stuff in the dark, hoping you'll stumble upon something.
