apache2(http2) on Docker

Posted at

【当研究室のシステム】

概要

Apache2 on Docker + php-fpm on Dockerからもう一歩,http2化してみる.
手順は以下のとおり.

  • mpm_freforkモジュールを無効化
  • mpm_eventモジュールを有効化
  • http2モジュールを有効化

前提

  • apache2用Dockerfile
    • ~/Docker/www/Dockerfile
  • php-fpm用Dockerfile
    • ~/Docker/php-fpm/Dockerfile
  • http2までのセットのためのdocker-compose.yml
    • ~/Docker/docker-compose.yml
  • その他
    • SSL/TLS接続の場合: 443ポート使用しか使わないので80ポートの分はもういいや

設定

apache2

confファイルなどの準備

mkdir -p ~/Docker/www/sites-available/
mkdir -p ~/Docker/www/conf/ssl.crt
mkdir -p ~/Docker/www/conf/ssl.key

ServerAdminおよびServerName(FQDN)は自分のものに合わせて設定しましょう.
中間CA証明書の名前はとりあえずnii-hogehogehoge.cerとする.
server.crt, nii-hogehogehoge.cer~/Docker/www/conf/ssl.crt/に,server.key~/Docker/www/conf/ssl.key/に入れておく.

~/Docker/www/sites-available/default-ssl.conf
<IfModule mod_ssl.c>
  <VirtualHost _default_:443>
    ServerAdmin webmaster@localhost
    ServerName my.domain.name.co.jp
    DocumentRoot /var/www/html

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    SSLEngine on

    SSLCertificateFile      /etc/apache2/conf/ssl.crt/server.crt
    SSLCertificateKeyFile /etc/apache2/conf/ssl.key/server.key
    SSLCertificateChainFile /etc/apache2/conf/ssl.crt/nii-hogehogehoge.cer
    <FilesMatch "\.(cgi|shtml|phtml|php)$">
      SetHandler "proxy:unix:/var/run/php-fpm/php-fpm.sock|fcgi://localhost"
      SSLOptions +StdEnvVars
    </FilesMatch>
    <Directory /usr/lib/cgi-bin>
      SSLOptions +StdEnvVars
    </Directory>
  </VirtualHost>
</IfModule>

Dockerfileの準備

~/Docker/www/Dockerfile
FROM ubuntu:22.04

RUN set -x && \
    apt update && apt upgrade -y && \
    DEBIAN_FRONTEND=noninteractive apt install -y \
       apache2 \
       locales && \
    locale-gen ja_JP.UTF-8

ENV TZ=Asia/Tokyo LANG=ja_JP.UTF-8 LANGUAGE=ja_JP:ja

COPY ./conf /etc/apache2/conf
COPY ./sites-available /etc/apache2/sites-available

ARG HOSTNAME=www # ホスト名として名前を適宜設定(ここではwww)

# 以下ではdefault.confもdefault-ssl.confも使用する設定
RUN echo ServerName $HOSTNAME > /etc/apache2/conf-available/fqdn.conf && \
    /usr/sbin/a2enconf fqdn && \
    /usr/sbin/a2dismod php8.1 && \
    /usr/sbin/a2dismod mpm_prefork && \
    /usr/sbin/a2enmod mpm_event && \
    /usr/sbin/a2enmod proxy_fcgi && \
    /usr/sbin/a2enmod setenvif && \
    /usr/sbin/a2enmod http2 && \
    /usr/sbin/a2dissite 000-default && \

    /usr/sbin/a2enmod ssl && \
    /usr/sbin/a2enmod authnz_ldap && \
    /usr/sbin/a2enmod rewrite

EXPOSE 80
EXPOSE 443

php-fpm

Dockerfileの準備

~/Docker/php-fpm/Dockerfile
FROM php:8.1.18-fpm-bullseye

RUN set -x && \
    curl -sSLf \
        -o /usr/local/bin/install-php-extensions \
        https://github.com/mlocati/docker-php-extension-installer/releases/latest/download/install-php-extensions && \
    chmod +x /usr/local/bin/install-php-extensions && \
    install-php-extensions curl

ENV TZ=Asia/Tokyo

# Use the default production configuration
RUN mv "$PHP_INI_DIR/php.ini-production" "$PHP_INI_DIR/php.ini" && \
    sed -i 's/memory_limit = 128M/memory_limit = -1/' "$PHP_INI_DIR/php.ini" && \
    sed -i 's/post_max_size = 8M/post_max_size = 20480M/' "$PHP_INI_DIR/php.ini" && \
    sed -i 's/upload_max_filesize = 2M/upload_max_filesize = 20480M/' "$PHP_INI_DIR/php.ini" && \
    sed -i 's/max_execution_time = 30/max_execution_time = 600/' "$PHP_INI_DIR/php.ini" && \
    sed -i 's/;max_input_vars = 1000/max_input_vars = 5000/' "$PHP_INI_DIR/php.ini" && \
    cp /usr/local/etc/php-fpm.d/www.conf /usr/local/etc/php-fpm.d/zzz-www.conf && \
    sed -i 's!pm.max_children = 5!pm.max_children = 10!' /usr/local/etc/php-fpm.d/zzz-www.conf && \
    sed -i 's!listen = 127.0.0.1:9000!listen = /var/run/php-fpm/php-fpm.sock!' /usr/local/etc/php-fpm.d/zzz-www.conf && \
    sed -i 's!;listen.owner = www-data!listen.owner = www-data!' /usr/local/etc/php-fpm.d/zzz-www.conf && \
    sed -i 's!;listen.mode = 0660!listen.mode = 0660!' /usr/local/etc/php-fpm.d/zzz-www.conf

docker-compose.yml

apache2, php-fpmを起動するdocker-compose.ymlを~/Dockerに作成.
apache2の内容は,nfs経由でマウントする.

~/Docker/docker-compose.yml
version: '3.9'

services:
  www:
    build: ./www
    image: nek/www:latest
    container_name: www
    hostname: www
    ports:
      - 443:443
    restart: always
    depends_on:
      - php-fpm
    volumes:
      - www_data:/var/www
      - socket:/var/run/php-fpm

  php-fpm:
    build: ./php-fpm
    image: nek/php-fpm:latest
    container_name: php-fpm
    hostname: php-fpm
    restart: always
    volumes:
      - www_data:/var/www
      - socket:/var/run/php-fpm
      - /etc/group:/etc/group:ro
      - /etc/passwd:/etc/passwd:ro

volumes:
  socket:
  www_data:
    driver_opts:
      type: nfs
      o: "port=2049,addr=192.168.0.2,rw,nfsvers=4"
      device: ":/apache2/www"
