【问题描述】：

我刚刚开始在sailsjs 中编码，我正在尝试将它连接到Mysql 数据库。我已经安装了“sails-mysql”。我还使用 mysql 命令创建了数据库。这些是我的“配置”文件的内容。一世连接.js

  mysql: {
adapter: 'sails-mysql',
host: '127.0.0.1',
port: 27017,
user: '', //optional
password: '', //optional
database: 'new_db',
schema: true //optional
}

models.js

module.exports.models = {
connection: 'mysql',
migrate: 'alter'
};

我在 'sails lift' 上收到此错误。

error: A hook (`orm`) failed to load!
error: Error (E_UNKNOWN) :: Encountered an unexpected error

此错误的原因可能是什么，我该如何解决？在此先感谢:)

【问题讨论】：

我遇到了类似的问题，删除了端口号键值对；让它在默认端口上运行并且它工作。似乎是端口号的问题。
错误仍然存在..

【解决方案1】：

您应该将 mysql 端口更改为 3306，因为 27017 用于 mongodb，添加 mysql 连接的用户名和密码，并通过在 mysql shell 上测试它来确保您传递了正确的凭据：-

mysql -u USERNAME -pPASSWORD -d DBNAME

这里是一个mysql-config的例子

module.exports.connections = {
  mysql: {
    module    : 'sails-mysql',
    host      : 'localhost',
    port      : 3306,
    user      : 'username',
    password  : 'password',
    database  : 'MySQL Database Name'

    // OR (explicit sets take precedence) 
    module    : 'sails-mysql',
    url       : 'mysql2://USER:PASSWORD@HOST:PORT/DATABASENAME'

    // Optional 
    charset   : 'utf8',
    collation : 'utf8_swedish_ci'
  }
};
