升级后无法访问AWS RDS实例
[英]Can't Access AWS RDS Instance after Upgrade
问题描述
Just upgraded my MySQL RDS instance from the free-tier db.t2.micro to an db.r3.large. 
刚刚将我的MySQL RDS实例从免费层db.t2.micro升级到db.r3.large。 Same storage, same security groups, same user groups/credentials, same VPC, same endpoint name, same everything. 相同的存储，相同的安全组，相同的用户组/凭据，相同的VPC，相同的端点名称，相同的所有内容。
I was previously able to access this same instance remotely through MySQL workbench before the upgrade, and according to AWS my endpoint location has not changed. 升级之前，我以前能够通过MySQL工作台远程访问同一实例，并且根据AWS，我的端点位置没有更改。
The error message received: 收到错误消息：
Can't connect to MySQL server on 'blahblah.rds.amazonaws.com' (10060)
I've tried restarting several times. 我尝试重新启动几次。 Ensured by security group allowed inbound TCP access on port 3306 for both 0.0.0.0/0 and ::/0 由安全组确保在端口3306上允许0.0.0.0/0和:: / 0的入站TCP访问
What else could be wrong? 还有什么可能是错的？

You probably need to restart the MySQL workbench, not reboot the RDS. 您可能需要重新启动MySQL工作台，而不是重新启动RDS。
As I described here , the database handles have changed, but the code doesn't notice. 正如我在这里描述的，数据库句柄已经更改，但是代码没有注意到。 So the MySQL workbench is using outdated handles that are being rejected. 因此，MySQL工作台正在使用被拒绝的过时句柄。
