可以從運行 network_mode: 'host' 的 docker 容器連接到在 localhost 上運行的 mysql

Question

我正在嘗試從 docker 容器訪問在主機上運行的 mysql。

在我的服務器上，我運行mysql版本為 5.7.39 。 我創建了新的 mysql 數據庫和用戶並授予了所有權限：

CREATE DATABASE strapi CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; 
CREATE USER 'strapi'@'localhost' IDENTIFIED BY 'password'; 
GRANT ALL PRIVILEGES ON strapi.* TO 'strapi'@'localhost';

我使用 network_mode: host 創建了我的 docker-compose 文件，以便我可以訪問主機上的 mysql：

version: '3.8'
services:
  strapi:
    image: naskio/strapi
    environment:
      NODE_ENV: production
      DATABASE_CLIENT: mysql
      DATABASE_HOST: localhost
      DATABASE_PORT: 3306
      DATABASE_NAME: strapi
      DATABASE_USERNAME: strapi
      DATABASE_PASSWORD: 'password'
      DATABASE_SSL: 'false'
    volumes:
      - ./app:/srv/app
    network_mode: 'host'

但是，它會不斷生成錯誤消息，簡短地說“訪問被拒絕”

要測試我是否可以直接從主機訪問，此命令成功執行：

mysql --default-auth=mysql_native_password --host=localhost --user=strapi --password='password' strapi

我不知道我可以檢查什么以使其運行。

我還可以在主機上的 /var/log/mysql/error.log 中看到：

2022-08-01T13:36:58.226683Z 5648 [Note] Access denied for user 'strapi'@'localhost' (using password: YES)

我不知道為什么它不起作用。 請幫忙。

Answer 1

您可能想查看 Docker 上的 Strapi v4指南。 這是 Strapi 推薦的。 我已經使用它，並且能夠從我的機器和 Docker 容器連接到 MySQL 數據庫。

您也可以考慮使用更新版本的 MySQL。
