英文:

MariaDB Connection refused (NGINX , MariaDB, php-fpm) SQLSTATE[HY000] [2002] Connection refused

问题

这是你的文档中的一部分内容:

"Getting SQLSTATE[HY000] [2002] Connection refused when sending query to MariaDB"
在发送查询到MariaDB时出现SQLSTATE[HY000] [2002]连接被拒绝的错误。

以下是你的docker-compose构建的链接:
https://github.com/bocasoftware/docker-compose

这是data.sql文件的链接(不在GitHub存储库中,因为文件太大,但它在我的构建中存在):
https://gitlab.com/x-team-blog/docker-compose-php/blob/master/docker/database/data.sql

这是你的文档树/布局:

这是你的index.php文件中的查询部分的代码:

<?php

$value = "World";

try {
    $db = new PDO('mysql:host=db;dbname=mydb;charset=utf8mb4', 'myuser', 'secret');

    $databaseTest = ($db->query('SELECT * FROM dockerSample'))->fetchAll(PDO::FETCH_OBJ);
} catch (Exception $e) {
    print $e->getMessage() . "\n";
}
print "OK\n";
?>

这是你的docker-compose.yml文件的一部分:

    build:

    volumes:

这是你的Docker容器的状态,使用docker ps命令查看:

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                                NAMES

Below is the link to my docker-compose build

--- IMPORTANT This is the data.sql file (NOT in the github repository file was too large but it is on my build):

https://gitlab.com/x-team-blog/docker-compose-php/blob/master/docker/database/data.sql

This is my document tree/layout:

myapp

Here is my index.php which has the query:

&lt;?php

$value = &quot;World&quot;;

try {
$db = new PDO(&#39;mysql:host=db;dbname=mydb;charset=utf8mb4&#39;, &#39;myuser&#39;, &#39;secret&#39;);

$databaseTest = ($db-&gt;query(&#39;SELECT * FROM dockerSample&#39;))- 
&gt;fetchAll(PDO::FETCH_OBJ);
} catch (Exception $e) {
print $e-&gt;getMessage() . &quot;\n&quot;;
}
print &quot;OK\n&quot;;
?&gt;

&lt;html&gt;
    &lt;body&gt;
        &lt;h1&gt;Hello, &lt;?= $value ?&gt;!&lt;/h1&gt;

        &lt;?php foreach($databaseTest as $row): ?&gt;
            &lt;p&gt;Hello, &lt;?= $row-&gt;name ?&gt;&lt;/p&gt;
        &lt;?php endforeach; ?&gt;
    &lt;/body&gt;
&lt;/html&gt;

Here is my docker-compose.yml:

version: '3'

services:

  app:
   build:
     context: ./app
   volumes:

      - MYSQL_ROOT_PASSWORD=docker
   volumes:

I do not understand what is going on. It seems I am reaching MariaDB but it's refusing my connection despite checking ports, user and password and pruning volumes, removing containers, deleting images and building them again from scratch.

docker ps:
