【问题描述】：

我正在尝试在 docker 桌面上运行没有任何错误的图像容器。当我尝试在 Digital Ocean 上运行相同的命令和存储库时，我收到了这个错误

error: connect ECONNREFUSED 127.0.0.1:3306

version: "3"
services:
  mysql:
    image: mysql
    command: mysqld --default-authentication-plugin=mysql_native_password
    volumes:
      - ./data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: strapi
      MYSQL_DATABASE: strapi
      MYSQL_USER: strapi
      MYSQL_PASSWORD: strapi

  strapi:
    image: strapiproje:latest
    environment:
      DATABASE_CLIENT: mysql
      DATABASE_HOST: mysql
      DATABASE_PORT: 3306
      DATABASE_NAME: strapi
      DATABASE_USERNAME: strapi
      DATABASE_PASSWORD: strapi
      DATABASE_SSL: "false"
    volumes:
      - ./app:/srv/app
    ports:
      - "1337:1337"
    depends_on:
      - mysql

我也尝试 DATABASE_HOST: 127.0.0.1 但没有任何改变有人对我有任何建议吗？

【问题讨论】：

你确定它在本地有效吗？ DATABASE_HOST 设置对我来说不合适；我希望它需要是其他 Compose 服务的名称 mysql。另见Docker - SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:3306。
实际上，我首先将其设置为 DATABASE_HOST : mysql 但也会发生此错误。无论如何我会再试一次

【解决方案1】：

您可能缺少从主机的端口 3306 到 docker 容器中相同端口的映射。您的 docker-compose.yml 文件应如下所示：

version: "3"
services:
  mysql:
    image: mysql
    command: mysqld --default-authentication-plugin=mysql_native_password
    volumes:
      - ./data:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD: strapi
      - MYSQL_DATABASE: strapi
      - MYSQL_USER: strapi
      - MYSQL_PASSWORD: strapi
    ports:
      - "3306:3306"   <----- notice these lines


  strapi:
    image: strapiproje:latest
    environment:
      DATABASE_CLIENT: mysql
      DATABASE_HOST: mysql
      DATABASE_PORT: 3306
      DATABASE_NAME: strapi
      DATABASE_USERNAME: strapi
      DATABASE_PASSWORD: strapi
      DATABASE_SSL: "false"
    volumes:
      - ./app:/srv/app
    ports:
      - "1337:1337"
    depends_on:
      - mysql
