Docker(更新中)

先说说为什么要写这篇文章，大概只是记录一下两天啥也没搞出来的痛苦，总不能啥也没学会吧

php7.3以上 + MariaDB

这个版本下面的MariaDB，不会自启动，需要进行初始化处理，同时，安装插件的过程比较抽象，某些部分也是需要看chatgpt以及文档慢慢调试

Dockerfile

FROM php:7.4-apache


RUN mv "$PHP_INI_DIR/php.ini-production" "$PHP_INI_DIR/php.ini"

# Update apt and install GD extension dependencies
RUN apt-get update && \
    apt-get install -y libfreetype6-dev libjpeg62-turbo-dev libpng-dev && \
    # Install GD extension
    docker-php-ext-configure gd --with-freetype --with-jpeg && \
    docker-php-ext-install -j$(nproc) gd

# Install PDO MySQL extension
RUN docker-php-ext-install pdo_mysql

# Install MySQLi extension
RUN docker-php-ext-install mysqli


# Install MariaDB 10.5
RUN apt-get install -y mariadb-server-core-10.5 mariadb-server-10.5 supervisor

RUN /etc/init.d/mariadb start && \
    mysql -e "CREATE USER 'test'@'%' IDENTIFIED BY 'test';" && \
    mysql -e "GRANT ALL PRIVILEGES ON *.* TO 'test'@'%' WITH GRANT OPTION;" && \
    mysql -e "" && \
    mysql -e "FLUSH PRIVILEGES;"

COPY . /var/www/html
COPY supervisord.conf /etc/supervisor/conf.d/supervisord.conf
WORKDIR /var/www/html

# Expose ports
EXPOSE 80
EXPOSE 3306

# Set the container's startup command to apache2-foreground and start MariaDB service
CMD ["/usr/bin/supervisord", "-c", "/etc/supervisor/conf.d/supervisord.conf"]


然后可以进行多线程操作

supervisord.conf

[supervisord]
nodaemon=true

[program:apache2]
command=apache2-foreground

[program:mariadb]
command=/etc/init.d/mariadb start

php7.2以下 + MariaDB

在较低版本下面的MariaDB，会直接自启动，所以并不需要多线程操作

较为粗糙来写的话，用下面的这个即可

php + mysql

对于不是在线进行安装的，不需要过多进行操作的，可以直接写docker-compose.yml + Dockerfile 进行处理

version: '3.0'
services:
  webserver:
    build: .
    ports:
      - "8081:80"
    links:
      - db
    volumes:
      - ./:/var/www/html 
  db:
    image: mysql:5.6
    command: --default-authentication-plugin=mysql_native_password
    environment:
      MYSQL_DATABASE: aaa
      MYSQL_USER: aaa
      MYSQL_PASSWORD: aaa
      MYSQL_ROOT_PASSWORD: rootroot
    volumes:
      - ./mysql-init-files:/docker-entrypoint-initdb.d  # 放置sql文件
    networks:
      - default

设置好文件以及sql文件就可以了

多容器手法

使用links或者depends_on，就可以将多个镜像和容器进行连接，然后进行处理（超过2个可以考虑depends_on，2个只要links）

类似于这样，如此就不太需要怎么样进行配置，至于前面的Dockerfile写得如此复杂，是因为在本地调试的时候放在一起更加方便一些(有时间我会写成yml)
