Amazon RDS和Elastic Beanstalk连接

问题描述

| 已经有几个线程讨论了这个问题，我已经尝试实现 Elastic Beanstalk->使用Grails的RDS连接错误。 我还打开了端口，以接受来自\“ All \”的EC2实例中的ICMP，TCP和UDP连接。 我确保我的RDS和EC2实例位于同一区域（东部） 我还在RDS默认安全组中添加了“ elasticbeanstalk-default \”安全组。 我已在RDS CIDR设置中添加了本地计算机的IP地址，并且能够从我的计算机通过SQLYog连接到RDS。 但是，当我尝试从Elastic Beanstalk连接我的RDS实例时，出现以下异常

我的DataSource.groovy参数如下。

production {
    dataSource {
        pooled = true
        dbCreate = \"update\" // one of \'create\',\'create-drop\',\'update\'
        url = \"jdbc:mysql://[MyEndPoint]:3306/*****\"
        username = \"*****\"
        password = \"*****\"
        dialect = org.hibernate.dialect.MySQL5InnoDBDialect
        properties {
            validationQuery = \"SELECT 1\"
            testOnBorrow = true
            testOnReturn = true
            testWhileIdle = true
            timeBetweenEvictionRunsMillis = 1000 * 60 * 30
            numTestsPerEvictionRun = 3
            minEvictableIdleTimeMillis = 1000 * 60 * 30
        }
    }
}

    

解决方法

        我解决了，但答案很愚蠢。 我总是觉得，在NetBeans中为Grails项目构建新的WAR文件时，它是在“生产”环境中创建的，但事实并非如此。我必须转到项目属性，并将“ Active Grails环境”设置更改为“生产”，然后对其进行了修复。 简而言之，Amazon Web Services Elastic Beanstalk尝试连接到我的开发环境数据库\“ localhost \”。
