Xdebug+VSCodeで再びハマったメモ。vagrant+virtualbox+ubuntu上のdocker上のphp+nginx

Last updated at Posted at 2018-09-05

概要

以前にxdebugを有効化したが、
バージョンを色々上げたら動かなくなった話。
動くようになったので、以下に動いた状態の設定を記す

動作環境

  • windows10
  • vagrant2.1.2
  • virtualbox5.2.18
  • ubuntu-18.04
  • Docker version 18.06.0-ce, build 0ffa825
  • docker-compose version 1.22.0, build f46880fe

設定

ホスト:Visual Studio Code の PHP DEBUGの設定

.vscode/launch.json
{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Listen for XDebug",
      "type": "php",
      "request": "launch",
      "port": 9001,
      "pathMappings": {
        "/var/www/html": "${workspaceRoot}/src"
      }
    }
  ]
}

ゲスト: nginxサーバの設定

server/nginx/server.conf
server {
    listen 80 default;
    server_name localhost;
    root /var/www/html;
    index index.php index.html index.htm;
    charset utf-8;
    access_log /var/log/nginx/access.log;
    error_log  /var/log/nginx/error.log;

    # access_log /data/access.log;
    # error_log  /data/error.log;

    location / {
        try_files $uri $uri/ /index.php$is_args$args;
    }
    location ~ \.php$ {
        # フォルダ名に合わせてphpfpmの部分を書き換える
        #fastcgi_pass phpfpm_php7_1:9000;

        # xdebugの初期ポートと競合する
        fastcgi_pass php7:9000;

        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include       fastcgi_params;
    }
}
server/php7/Dockerfile
FROM php:7-fpm
RUN apt-get update 
RUN docker-php-ext-install pdo_mysql

RUN pecl install xdebug
RUN echo "zend_extension=$(find /usr/local/lib/php/extensions/ -name xdebug.so)" > /usr/local/etc/php/conf.d/xdebug_settings.ini 

RUN echo '\
log_errors = On\n\
error_log =/dev/stderr\n\
error_reporting = E_ALL\n\
display_errors = On\n\
' >> /usr/local/etc/php/conf.d/docker.ini

環境変数でXdebugの設定を行うようにした。 remote_host=10.0.2.2の設定が必要になった。

docker-compose.yml
version: "3"
services:
  # サーバー
  nginx: 
    build: ./server/nginx
    ports: 
      - 80:80
    volumes:
      - ./server/nginx/server.conf:/etc/nginx/conf.d/server.conf
      - ./src:/var/www/html

  # php
  php7: 
    build: ./server/php7
    volumes:
      - ./src:/var/www/html
      - ./server/php7/php.ini:/usr/local/etc/php/php.ini
    environment:
      # 9000番はfast-cgiが使っているので1つずらす
      XDEBUG_CONFIG: "remote_enable=1 remote_autostart=1 remote_port=9001 remote_host=10.0.2.2"

  # データベースへアクセス
  adminer:
    image: adminer
    ports: 
      - "8081:8080"

  # データベース
  db:
    build: ./server/mysql
    volumes:
      - dbdata:/var/lib/mysql
      - /etc/localtime:/etc/localtime:ro # 時刻の同期
      - ./server/mysql/init:/docker-entrypoint-initdb.d # 初期実行
    ports:
      - 3306:3306
    environment:
      MYSQL_ROOT_PASSWORD: "password"
      TZ: "Asia/Tokyo"

volumes:
  dbdata: # 名前付きボリューム名
