Question

我可以从sqlyog连接数据库，但是当从nodejs连接时出现以下错误：

数据库IP：10.0.0.200

  sqlMessage: 'Access denied for user \'myuser\'@\'10.0.0.100\' to database \'db_new\'',
  sqlState: '42000',
  fatal: true }

连接数据库的代码

connection = mysql.createConnection({
    host: settings.dbhost,
    user: settings.user,
    password: settings.password,
    database: settings.database
});

遇到此问题时，一个常见的问题是未授予用户所有特权。要授予所有特权，您可以按照mysql的建议执行SQL命令，

mysql> show grants;
+-------------------------------------------------------------------------------------------------------------+
| Grants for RollingRidge@%                                                                                   |
+-------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'RollingRidge'@'%' IDENTIFIED BY PASSWORD '*REDACTED'                                 |
| GRANT ALL PRIVILEGES ON `rollingridge`.* TO 'RollingRidge'@'%'                                              |

希望这会有所帮助。
