遇到 PHP 错误（HY000/2002）：连接被拒绝

Question

Severity: Warning Message: mysqli::real_connect(): (HY000/2002): Connection refused Filename: mysqli/mysqli_driver.php Line Number: 201

Code:

    if ($this->_mysqli->real_connect($hostname, $this->username, $this->password, $this->database, $port, $socket, $client_flags))

Answer 1

This error happens before your username and password are checked.

Make sure your $hostname is correct. If your database is running locally, make sure it's also bound to an IP address, not just a socket (alternatively, set $hostname to the socket path).
