Question

我创建了一个简单的Sails.JS测试应用

sails new test-project

我只想测试与我的NAS上运行的MariaDB的连接是否正常工作，以及我是否可以使用Sails.JS中的蓝图来解决它。

我创建了一个简单的数据库：

和testuser：

我配置 config / datastores.js 如下：

module.exports.datastores = {
  default: {
    adapter: 'sails-mysql',
    url: 'mysql://asd:asd@192.168.178.11:3306/asd'
  },
};

我的 config / models.js 如下所示：

module.exports.models = {
  migrate: 'safe',
  attributes: {
    createdAt: { type: 'number', autoCreatedAt: true, },
    updatedAt: { type: 'number', autoUpdatedAt: true, },
    id: { type: 'number', autoIncrement: true, },
  },

  dataEncryptionKeys: {
    default: 'XYZ='
  },

  cascadeOnDestroy: true
};

完成所有操作后，我创建了一个“API”文件：

sails generate api asd

创建了我的模型文件，反过来我完成了以下内容：

/**
 * Asd.js
 *
 * @description :: A model definition.  Represents a database table/collection/etc.
 * @docs        :: https://sailsjs.com/docs/concepts/models-and-orm/models
 */

module.exports = {

  attributes: {
      name: {
          type: 'string'
        }
  }

};

我现在的期望是我可以使用Postman使用REST API查看连接是否有效。所以我解除了项目并简单地发出了一个GET请求

http://localhost:1337/asd/1

产生以下错误

AdapterError: Unexpected error from database adapter: `select` failed ("badConnection").  A connection either could not be obtained or there was an error using the connection.

我可以使用asd-User使用PHPMyAdmin登录，但Sails-JS的连接失败。

[EDIT-1] 我使用PHPMyAdmin重新创建了包含权限的用户，这是它执行的命令

CREATE USER 'asd'@'%' IDENTIFIED VIA mysql_native_password USING '***';
GRANT USAGE ON *.* TO 'asd'@'%' REQUIRE NONE WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0;
GRANT ALL PRIVILEGES ON `asd`.* TO 'asd'@'%' WITH GRANT OPTION;

[/ EDIT-1]

[EDIT-2] 我尝试配置我的sails应用程序连接到数据库和主机名的IP。两者都不起作用，与上述相同。

CREATE USER 'asd'@'Markus-Desktop.fritz.box' IDENTIFIED VIA mysql_native_password USING '***';
GRANT USAGE ON *.* TO 'asd'@'Markus-Desktop.fritz.box' REQUIRE NONE WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0;
GRANT ALL PRIVILEGES ON `asd`.* TO 'asd'@'Markus-Desktop.fritz.box' WITH GRANT OPTION;

CREATE USER 'asd'@'192.168.178.34' IDENTIFIED VIA mysql_native_password USING '***';
GRANT USAGE ON *.* TO 'asd'@'192.168.178.34' REQUIRE NONE WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0;
GRANT ALL PRIVILEGES ON `asd`.* TO 'asd'@'192.168.178.34' WITH GRANT OPTION;

Answer 1

我的NAS上的MariaDB实例在端口3307上运行，而不是在配置的3306上运行。注意到在读取数据库实例的my.cnf时。

Sails.JS 1.0.0：与MariaDB的连接不起作用
