使用docker-compose搭建的wordpress怎么修改php.ini

我们创建wordpress的时候要创建.yml文件内容如下

version: '3.3'

services:
  db:
    image: mysql:5.7
    volumes:
      - db_data:/var/lib/mysql
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: example_root_password
      MYSQL_DATABASE: example_database
      MYSQL_USER: example_user
      MYSQL_PASSWORD: example_password

  wordpress:
    depends_on:
      - db
    image: wordpress:latest
    ports:
      - "8000:80"
    restart: always
    volumes:
      - wp_data:/var/www/html
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_NAME: example_database
      WORDPRESS_DB_USER: example_user
      WORDPRESS_DB_PASSWORD: example_password
volumes:
  db_data:
  wp_data:

把内容修改一下新增一个 volume 映射，将本地的 php.ini 文件映射到容器内的 /usr/local/etc/php/php.ini 文件，从而实现自定义 php.ini 配置文件。

version: '3.3'

services:
  db:
    image: mysql:5.7
    volumes:
      - db_data:/var/lib/mysql
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: example_root_password
      MYSQL_DATABASE: example_database
      MYSQL_USER: example_user
      MYSQL_PASSWORD: example_password

  wordpress:
    depends_on:
      - db
    image: wordpress:latest
    ports:
      - "8000:80"
    restart: always
    volumes:
      - ./php.ini:/usr/local/etc/php/php.ini
      - wp_data:/var/www/html
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_NAME: example_database
      WORDPRESS_DB_USER: example_user
      WORDPRESS_DB_PASSWORD: example_password
volumes:
  db_data:
  wp_data:

然后我们创建php.ini文件内容修改如下

post_max_size = 32M
upload_max_filesize = 32M
memory_limit = 256M
