尝试连接时出现“ SQLSTATE [HY000] [2006] MySQL服务器已消失”

Question

I am attempting to connect to MySQL server on my personal computer (Ubuntu 18.04.1 LTS) from a web browser, using url: http://localhost/Test.php

In Test.php I have the following code:

$pdo = new \\PDO("mysql:host=localhost;dbname=mydatabase", "root", "password");

I can connect successfully using command line mysql -u root -p (and use USE , SELECT , UPDATE ...). Mysql service is running.

Any idea of what's wrong?

Answer 1

Solved. I just created a new user, example:

CREATE USER 'select_user'@'localhost' IDENTIFIED BY 'password';

GRANT SELECT ON *.* TO 'select_user'@'localhost';

And changed user "root" to "select_user" in my php code. Using user "root" was the problem.
