码头-堆肥LEMP :错误:找不到司机

Question

我正试图在Linux中用docker-组合创建LEMP，我设法让PHP、NGINX和MySQL为我工作，但是当从php文件连接到DB时，它会返回异常：could not find driver。

这是我的docker-复合. file文件

web:
    build: .
nginx:
  image: tutum/nginx
  ports:
    - "80:80"
  volumes:
    - ./sites-available/default:/etc/nginx/sites-available/default
    - ./sites-available/default:/etc/nginx/sites-enabled/default

    - ./logs/nginx-error.log:/var/log/nginx/error.log
    - ./logs/nginx-access.log:/var/log/nginx/access.log

phpfpm:
  image: php:fpm
  ports:
    - "9000:9000"
  volumes:
    - ./public_html:/usr/share/nginx/html

mysql:
  image: mysql:5.7
  command: --default-authentication-plugin=mysql_native_password
  restart: always
  ports:
    - "33061:3306"
  volumes:
    - ./public_html/Model:/docker-entrypoint-initdb.d
  environment:
    MYSQL_DATABASE: tienda
    MYSQL_USER: user
    MYSQL_PASSWORD: user
    MYSQL_ROOT_PASSWORD: root

这是我的DockerFile

FROM php:7.2.19-apache-stretch

# PHP extensions
RUN docker-php-ext-install mysqli pdo pdo_mysql

这是连接到DB的PHP文件

<?php
abstract class TiendaDB {
private static $server = 'localhost';
private static $db = 'tienda';
private static $user = 'root';
private static $password = 'root';
public static function connectDB() {
try {
$connection = new PDO("mysql:host=".self::$server.";dbname=".self::$db.";charset=utf8", self::$user, self::$pass>} catch (PDOException $e) {
echo "No se ha podido establecer conexión con el servidor de bases de datos.<br>";
die ("Error: " . $e->getMessage());
}
return $connection;
}
}

我设法解决了这个问题，我添加了@β.εηοιτ.βε的Dockerfile文件，它给了我另一个错误，所以我又做了一次，它对我起了作用：

文件夹结构：

DOCKER_LEMP
├── app                 # All of your php file should be placed here, treat it like /var/www directory
│   └── index.php       # Default index file
├── database            # The database is saved here
├── nginx               # This folder contains nginx specified configuration
│   └── default.conf    # Default configuration file
├── php                 # Contains custom PHP7-fpm docker configuration
│   └── Dockerfile      # Docker configuration file for PHP container
├── docker-compose.yml  # Docker configuration for this project
└── readme.md           # Description for this project

Nginx：

server {
    listen 80;
    index index.php index.html;
    server_name localhost;
    error_log  /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;
    root /app;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

Dockerfile配置：
