【问题描述】：
这是我的问题：我的 WordPress 网站和 phpMyAdmin 无法访问 MySQL。
我正在使用 Centos 7 和 MySQK 8.0.18 for Linux on x86_64（MySQL 社区服务器 - GPL）。
我尝试了很多东西，但我不知道出了什么问题。
我已经尝试过的背景
-我有另一个由纯 php 制作的网站，它能够使用 mysqli 连接到我的数据库。
-我尝试重新安装了几次 MySQL、phpMyAdmin 和 PHP。
-禁用连接phpmyadmin的密码
-为testuser授予所有数据库的所有权限
-我能够正确连接到mysql：mysql -u root -p
-testuser 拥有所有数据库的所有权限（hes like root）
PHPMYADMIN 配置 (/etc/phpMyAdmin/config.inc.php)：
<?php

* configuration. For easier setup you can use "setup/".

The errors I get:
WordPress error : Error establishing a database connection
PhpMyAdmin error: Cannot log in to the MySQL server
I can access phpMyAdmin (mywebsite.com/phpMyadmin/index.php)
I can access my databases with another test website I made out of pure php.
