一个主机上的多个wordpress

我正在尝试在主机上部署多个WordPress。我使用nginx将连接分发到好的子域。

我成功部署了第一个带有WordPress和MySQL服务器的容器。使用此脚本：

＆＃13;
＆＃13; 
version: '2'

services:
   db3:
     image: mysql:5.7
     volumes:
       - db_wp_lmt_data:/var/lib/mysql
     restart: always
     ports:
       - 3308:3306
       - 3308
     environment:
       MYSQL_ROOT_PASSWORD: FFFF
       MYSQL_DATABASE: DDDD
       MYSQL_USER: XXX
       MYSQL_PASSWORD: YYYY
   wordpress:
     depends_on:
       - db3
     image: wordpress:latest
     ports:
       - "8003:80"
     restart: always
     environment:
       WORDPRESS_DB_HOST: db3:3306
       WORDPRESS_DB_USER: XXX
       WORDPRESS_DB_PASSWORD: YYYY
       VIRTUAL_HOST: ZZZZZ
     volumes:
       - wp_lmt_data:/var/www/html
volumes:
    db_wp_lmt_data:
    wp_lmt_data:
networks:
  default:
    external:
      name: nginxproxy_default
＆＃13;
＆＃13;
＆＃13;

然而，当我添加第二个具有相同脚本（在将端口从8003更改为8004和3308到3009之后）时，我遇到了一些麻烦。可以从外部访问mysql服务器，但wordpress不起作用。当我从主持人＆＃34; curl -k localhost：8004＆＃34;它没有返回任何内容，而另一个wordpress返回主页内容。

我试图理解为什么它不起作用，并解决它。但现在我不知道如何解决它。

此外，我在附加模式下启动容器，一切看起来都很好：

我终于找到了一种方法来做我想做的事。我删除了我的docker-compose.yml并从头开始。

我改用了这个脚本：

version: '2'

services:
    wordpress:
        image: wordpress
        links:
         - mariadb:mysql
        environment:
         - WORDPRESS_DB_PASSWORD=XXX
         - VIRTUAL_HOST= YYY
        ports:
         - "10001:80"
         - 10001
        expose:
         - 10001
        volumes:
         - mywordpressvolume:/var/www/html

    mariadb:
        image: mariadb
        environment:
         - MYSQL_ROOT_PASSWORD=XX
         - MYSQL_DATABASE=wordpress
        volumes:
         - mydbvolume:/var/lib/mysql

volumes:
    mywordpressvolume:
    mydbvolume:
    
networks:
  default:
    external:
      name: nginxproxy_default

这给了我一个有效的WordPress。我仍然困惑为什么WordPress有这种行为。也许WordPress无法访问数据库是有原因的，我想知道使用链接服务名称是否是一个好习惯。然后，我使用了命令

  

docker exec mycontainername env | grep“VIRTU”

检查我的容器使用的所有VIRTUAL_HOST变量。最后，它结束了。
