[Resolved] Mysqli

Hello !
I want to connect to my database, but that doesn't work... :'(
With the same code on my webserver, that works, but with PocketMine-MP, that said an error

Code:

Warning: mysqli::__construct(): (HY000/2002): No such file or directory

Here is my code:

PHP:

<?php
namespace be\minesylv\Database;

use pocketmine\plugin\PluginBase;

class Main extends PluginBase {
    private $db;
 
    public function onLoad(){
        $this->saveDefaultConfig();
        $host = $this->getConfig()->get('host');
        $user = $this->getConfig()->get('user');
        $pswd = $this->getConfig()->get('password');
        $database = $this->getConfig()->get('database');
        if($host == "127.0.0.1"){
            $host = "localhost";
        }
        $this->db = new \mysqli('localhost','user','password','database_name');
        //$this->db = new \mysqli($host,$user,$pswd,$database);
        if(!empty($this->db->connect_errno)){
         $this->getLogger()->error('Can\'t connect to database : ' .$this->db->connect_errno . ' | ' .$this->db->connect_error);
        } else {
         $this->getLogger()->info('Successfully connected to the Database');
        }
        $this->getLogger()->info(php_ini_loaded_file());
    }
    public function getDB(){
     return $this->db;
    }
}

Thank you in advance for your answer !
Whaxion

 

Use 127.0.0.1 instead of localhost when connecting.

 

Thanks for your answer, but with 127.0.0.1 I have another error

Code:

Warning: mysqli::__construct(): (HY000/2002): Connection refused

 

This means that there is no MYSQL server running on port 3306 on your local machine. Try restarting it or make sure you have your port correct.

 

The server is started and on port 3306...
I already try to restart it but that didn't change anything

 

Did you already do mysql_secure_installation? (If your on linux ubuntu) Otherwise I recommend taking a look at your MYSQL configuration

 

I don't know what is mysql_secure_installation... :/
My server is on Debian 8 and this is my mysql configuration

Code:

#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.

Thanks you to try to help me

 

Better comment out the bind address part.

Code:

#bind-address        = 188.165.160.96

 

That's resolve my problem !
Thanks !

 

Glad you fixed it
