rancher部署三个Wordpress docker-compose.yml脚本

好的，下面是部署三个WordPress的docker-compose.yml脚本：

version: '3'

services:
  db1:
    image: mysql:5.7
    volumes:
      - db1-data:/var/lib/mysql
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: example
      MYSQL_DATABASE: wordpress1
      MYSQL_USER: wordpress1
      MYSQL_PASSWORD: password

  wordpress1:
    depends_on:
      - "8001:80"
    restart: always
    environment:
      WORDPRESS_DB_HOST: db1:3306
      WORDPRESS_DB_NAME: wordpress1
      WORDPRESS_DB_USER: wordpress1
      WORDPRESS_DB_PASSWORD: password
    volumes:
      - wp1-data:/var/www/html

  db2:
    image: mysql:5.7
    volumes:
      - db2-data:/var/lib/mysql
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: example
      MYSQL_DATABASE: wordpress2
      MYSQL_USER: wordpress2
      MYSQL_PASSWORD: password

  wordpress2:
    depends_on:
      - "8002:80"
    restart: always
    environment:
      WORDPRESS_DB_HOST: db2:3306
      WORDPRESS_DB_NAME: wordpress2
      WORDPRESS_DB_USER: wordpress2
      WORDPRESS_DB_PASSWORD: password
    volumes:
      - wp2-data:/var/www/html

  db3:
    image: mysql:5.7
    volumes:
      - db3-data:/var/lib/mysql
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: example
      MYSQL_DATABASE: wordpress3
      MYSQL_USER: wordpress3
      MYSQL_PASSWORD: password

  wordpress3:
    depends_on:
      - "8003:80"
    restart: always
    environment:
      WORDPRESS_DB_HOST: db3:3306
      WORDPRESS_DB_NAME: wordpress3
      WORDPRESS_DB_USER: wordpress3
      WORDPRESS_DB_PASSWORD: password
    volumes:
      - wp3-data:/var/www/html

volumes:
  db1-data:
  wp1-data:
  db2-data:
  wp2-data:
  db3-data:
  wp3-data:

以上的脚本通过Docker Compose来部署三个WordPress实例，每个实例都有一个MySQL数据库进行支持，并且每个实例的端口都不同（8001、8002和8003）。在使用时，可以将上面的脚本保存为docker-compose.yml文件，然后在该文件所在目录执行 `docker-compose up -d` 命令即可启动三个WordPress实例。注意需要提前安装好Docker和Docker Compose。
