Azure ACI Wordpress 模板建立数据库连接时出错

Question

你好 Azure 容器专家

我正在尝试配置以下 Azure 容器设置：

我的第一步（为简单起见）是在 Azure 上的单个容器组中创建 2 个容器（没有文件共享）。我创建了以下 Azure 资源管理器模板来创建 ACI

我在下面的博客中使用这里

      }
    }
}

为了执行 ARM 模板，我使用了以下语句：

az group deployment create -n TestDeployment -g rg-WordPress  --template-file "azuredeploy.json"

成功部署后，我访问了 public URL。我希望看到 WordPress 安装页面的地方。但是，我收到以下错误：

Error establishing a database connection

Answer 1

您的 ARM 模板中存在一些错误，例如 WORDPRESS_DB_HOST 的值应该是 "127.0.0.1:3306" 而不是 "127.0.0.0:3306" 并且端口号应该是 "port": 3306 而不是"port": "3306"。此外，图像 wordpress 对我不起作用，相反，使用图像 wordpress:4.9-apache 有效。
