Sails.JS 1.0.0：无法连接到 MariaDB

【问题标题】：Sails.JS 1.0.0: Connection to MariaDB does not workSails.JS 1.0.0：无法连接到 MariaDB
【发布时间】：2018-04-03 19:58:21
【问题描述】：

我创建了一个简单的 Sails.JS 测试应用

sails new test-project

我只是想测试在我的 NAS 上运行的 MariaDB 的连接是否有效，以及我是否可以使用 Sails.JS 中的蓝图来玩弄它。

我创建了一个简单的数据库：

和一个测试用户：

我将 config/datastores.js 配置如下：

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

我的 config/models.js 看起来像：

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
};

完成所有这些后，我创建了一个“API”文件：

sails generate api asd

它创建了我的模型文件，而我又完成了以下内容：

/**
 * 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通过 Postman 使用 REST API 来查看连接是否有效。 所以我解除了项目并简单地触发了一个 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，但来自 Sails-JS 的连接失败。

[编辑-1] 我重新创建了用户，包括使用 PHPMyAdmin 的权限，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]

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

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;

[/EDIT-2]

【问题讨论】：

  • 您的应用程序和数据库服务器是在不同的机器上吗？...我看不到有关您如何创建测试用户的图片...您可以添加您使用的说明吗?
  • 我编辑了我的帖子，其中包含有关如何配置 asd 用户以及应用程序在另一台机器上运行然后是数据库的信息
  • 您在创建用户时有一个小错误...应该是CREATE USER 'asd'@'IP'，其中的IP应该是试图与服务器连接的机器的IP。
  • 见[EDIT-2]。同样的错误。我尝试设置 IP 和主机名
  • 您也可以运行flush privileges 并重新启动数据库服务器，然后再试一次！

【解决方案1】：

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