问题描述

从EC2实例I-78a8df00,我试图连接到RDS实例MySQL的。 * 的**的 * .US东-1.rds.amazonaws.com。它们都在美国东部地区。我加EC2实例的安全组(SG-的 * 的* )到RDS安全组,但是这并没有帮助。这似乎是一个防火墙/ DNS问题,因为它是运行此命令时超时:

From EC2 instance i-78a8df00, I'm trying to connect to RDS instance mysql.****.us-east-1.rds.amazonaws.com. They are both in the U.S. East region. I added the security group of EC2 instance (sg-**) to the RDS security group, but that didn't help. It appears to be a firewall/DNS issue as it is timing out when running this command:

Ubuntu的@ IP-10-195-189-237:〜$ mysql的-h的mysql的 * 的**的 * .us- east-1.rds.amazonaws.com ERROR 2003(HY000):无法连接到MySQL服务器上的MySQL的的 * 的**的 * .US - 东 - 1.rds。 .amazonaws.com'(110)

ubuntu@ip-10-195-189-237:~$ mysql -h mysql.****.us-east-1.rds.amazonaws.com ERROR 2003 (HY000): Can't connect to MySQL server on 'mysql.****.us-east-1.rds.amazonaws.com' (110)

我可以从我的本地机器使用同一条线路与上述连接的RDS实例的罚款。我尝试了各种论坛,解决方案,但这些并不能帮助。

I can connect to RDS instance fine from my local machine using the same line as above. I tried various forum solutions but those don't help.

谢谢, 马克
