docker-composeを利用して古いphpシステムを動作させる、conoha vpsで

mocotech

あんまりやりたくないけど…ここではMoodle 1.9.19+としましょうか。

Moodle 1.9.19+

ここにしぶとく残っていたりする。

path

pathはさまざまな議論があると思うけど
/opt/moodle-deployment

にしまーす

$ sudo mkdir /opt/moodle-deployment
$ cd /opt/moodle-deployment/
$ sudo chown <ユーザー> .

とかしといたらいいんじゃないでしょうか

最低限のdocker-compose.yml

とりあえずtests/index.phpを表示するapacheを起動するとする

まず/opt/moodle-deployment/tests/index.phpを作成

$ mkdir tests
$ echo '<?php phpinfo();' > tests/index.php

でdocker-compose.yamlを作成

version: '3'

services:
  web:
    image: php:5.6-apache
    ports:
      - "80:80"
    volumes:
      - ./tests:/var/www/html

up

php5.6.40…

phpの設定をチューニングするための設定

これはカスタムイメージphp:5.6-apacheを使う最低限の設定ではあるが、mysql拡張が有効になっていないなど諸々の問題がある。

以下はchatgpt提案の構造だ

/opt/moodle-deployment
├── docker-compose.yml
├── php
│   └── Dockerfile
├── moodle
│   └── ... (Moodle source files)
└── moodledata
    └── ... (Moodle data files)

この php/Dockerfileで基本的なビルドを行う

# 基本イメージを選択
FROM php:5.6-apache

# 必要なパッケージとPHP拡張機能をインストール
RUN apt-get update && \
    apt-get install -y libpng-dev libjpeg-dev libxml2-dev && \
    docker-php-ext-configure gd --with-jpeg-dir=/usr/include/ && \
    docker-php-ext-install gd xmlrpc mysqli

これにより、gd、xmlrpc、mysqliが有効になる、はず

debianのphp5-gdパッケージとかは使えないから注意してほしい

ここで問題が生じる

古いのを動かすのはテクが要るンだよ…

このapt-lineはもう使えねえの。だからarchive.debian.orgに書き換えにゃならん。

まあ、問題だけわかってればchatgptに全部聞いたらいい。このようにsources.listを新しい値で強制上書きする

# 基本イメージを選択
FROM php:5.6-apache

# aptのリポジトリ設定を更新
RUN echo "deb http://archive.debian.org/debian/ stretch main contrib non-free" > /etc/apt/sources.list && \
    echo "deb-src http://archive.debian.org/debian/ stretch main contrib non-free" >> /etc/apt/sources.list && \
    echo "Acquire::Check-Valid-Until false;" > /etc/apt/apt.conf


# 必要なパッケージとPHP拡張機能をインストール
RUN apt-get update && \
    apt-get install -y libpng-dev libjpeg-dev libxml2-dev && \
    docker-php-ext-configure gd --with-jpeg-dir=/usr/include/ && \

ビルドする

docker-compose build --no-cache

--no-cacheは何となく付けといてもこれくらいの規模なら大丈夫、か？。

enableして

# systemctl enable docker
Synchronizing state of docker.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable docker

restart always
を付けつつ

docker-compose up -d

すると

$ docker ps
CONTAINER ID   IMAGE                   COMMAND                  CREATED         STATUS         PORTS                               NAMES

など上がってくる

自動起動完了後の設定

mysqlの設定も書き加える。やはりrestart: alwaysする

version: '3'

services:
  web:
    build: ./php/
    ports:
      - "80:80"
    volumes:
      - ./tests:/var/www/html
    restart: always
  db:
    image: mysql:5.6
    environment:
      - MYSQL_DATABASE=moodle
      - MYSQL_USER=moodle
      - MYSQL_PASSWORD=password
      - MYSQL_ROOT_PASSWORD=root_password
    volumes:
      - ./db_data:/var/lib/mysql
    restart: always

down からの upとかしてmysqlがpullされればokっちゃok。これもシステムの再起動テストをしておいてもよいだろう。

$ docker ps
CONTAINER ID   IMAGE                   COMMAND                  CREATED         STATUS          PORTS                               NAMES

mysql5.6が上がっとる

moodle

  web:
    build: ./php/
    ports:
      - "80:80"
    volumes:
      - ./moodle:/var/www/html
    restart: always

volumeを変更してmoodleのソースツリーディレクトリを与える

あやしい…

まあ、あやしいこともあるでしょうな

このシステムはdataディレクトリを用意する必要があるから、docker-compose.yamlを適当に変更してそれを作っておく。

version: '3'

services:
  web:
    build: ./php/
    ports:
      - "80:80"
    volumes:
      - ./moodle:/var/www/html
      - ./moodle_data:/var/moodledata
    restart: always
  db:
    image: mysql:5.6
    environment:
      - MYSQL_DATABASE=moodle
      - MYSQL_USER=moodle
      - MYSQL_PASSWORD=password
      - MYSQL_ROOT_PASSWORD=root_password
    volumes:
      - ./db_data:/var/lib/mysql
    restart: always

権限を揃えておく

$ sudo chown www-data moodle moodle_data/ -R


設定にもとづき適当に設定する。passwordはもうちょいしっかりした方がええかもな。serverはこの場合コンテナをdbにしたからdbである。

おっと

おこられたねーw
単純にmysqliにすればいいってことだったみたい

モジュールチェックok
言語はもう古すぎてオンラインダウンロード不可能

何でもかんでも揃うと思っていたらアカンわね。


つわけで何かかんか動かすなど。

DBとかデーターとか

まあこういうのは大抵引き継ぎ案件だと思うんだけど、DBはmysqlのdumpを取ってきて入れるだけ。そのときゃdocker-compose exec -Tとか使う必要があるかもしれぬ
