问题描述
从EC2实例I-78a8df00，我试图连接到RDS实例MySQL的。 * 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 * 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**的 * 的 .us- east-1.rds.amazonaws.comERROR 2003（HY000）：无法连接到MySQL服务器上的MySQL的的的 * 的**的 * 的 .US - 东 - 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
