DockerでApache+PHP+MySQLの環境を構築してみる

Posted at

概要

Dockerを使ってApache+PHP+MySQLの環境を構築してみたので手順を記載して行く。

ディレクトリ構成

ディレクトリ
 |_docker-compose.yaml
 |_Dockerfile
 |_config
 |   |_mysql
 |   |   |_my.cnf
 |   |     |_my.conf
 |   |_php
 |       |_php.ini
 |_html
     |_index.php
     |_connect.php

手順

各種ファイルの作成をする。

docker-compose.yamlの作成

version: '3.7'
services:
    web:
        build: .
        container_name: "php74-1"
        volumes:
            - "./html/:/var/www/html"
        privileged: true
        ports:
            - "80:80"
        depends_on:
            - mysql
    mysql:
        image: mysql:8
        volumes:
            - ./mysql:/var/lib/mysql
            - ./config/mysql/my.cnf:/etc/mysql/conf.d/my.cnf
        environment:
            - MYSQL_ROOT_PASSWORD=root
            - MYSQL_DATABASE=test_db
            - MYSQL_USER=test_user
            - MYSQL_PASSWORD=test_password
        ports:
            - "4306:3306"
        container_name: mysql8-1

Dockerfileの作成

FROM php:7.4.8-apache

RUN apt-get update && apt-get install -y \
    libonig-dev \
  && docker-php-ext-install pdo_mysql mysqli


COPY ./config/php/php.ini /usr/local/etc/php/

configファイルの作成

my.confの作成

config/mysql/my.cnfフォルダ配下に作成

[mysqld]
default_autentication_plugin=mysql_native_password

php.iniの作成

[Date]
date.timezone = "Asia/Tokyo"

phpファイルの作成

index.phpの作成

phpinfoを表示するように記述する。

<?php
    phpinfo();

connect.phpの作成

DBとの接続確認用のコードを記述する。

<?php 
    try {
        $dsn = 'mysql:host=mysql;dbname=test_db;charset=utf8';
        $db = new PDO($dsn, 'test_user', 'test_password');

        $sql = 'SELECT version();';
        $contact = $db->prepare($sql);
        $contact->execute();
        $result = $contact->fetchAll(PDO::FETCH_ASSOC);
        var_dump($result);
    } catch (PDOException $e) {
        echo $e->getMessage();
        exit;
    }

実行

docker-compose up -dコマンドで起動する。
