SequelizeConnectionRefusedError：连接ECONNREFUSED 127.0.0.1:3306 AWS RDS

Question

“ SequelizeConnectionRefusedError：连接ECONNREFUSED 127.0.0.1:3306”此错误不会使我连接到在AWS中创建的数据库实例。我已经在Github存储库的.env文件中更改了数据库配置。

代码如下：

const Sequelize = require("sequelize");
 const sequelize = new Sequelize(process.env.DATABASE, process.env.DATABASE_USER, 
  process.env.DATABASE_PASSWORD, {
   host: process.env.DATABASE_HOST,
   dialect: 'mysql',
   // operatorsAliases: false,
   pool: {
   max: 5,
   min: 0,
   acquire: 30000,
   idle: 10000,
  },
});
