I am trying to evaluate AWS RDS to use as possible DB for our application. I have created a DBInstance(micro) and added IP security group. I am able to connect to the DBInstance from Xampp shell command line and i am able to run queries from that.

But when i try to connect with workbench to the same DBInstance, it gives me error that 'MySQL server has gone away'. Following are the steps i followed to connect with workbench:

  1. Give the Endpoint address of DBInstance as Hostname.
  2. Port : 3306
  3. Set the username and password to master user and its password.

My database is completely new, I have just created a plain DB and trying to connect with workbench right away. I am using workbench version 5.2.25.

Any ideas on what am i missing? And yes, I am just a beginner with MySQL and AWS.

Edit: As asked by RolandoMySQLDBA, i have run the query SELECT USER(),CURRENT_USER(); and in the result i get one row with two columns USER() and CURRENT_USER()=ei@%. ei is the master username for my RDS DBInstance. And the column USER() has my ip address after @.

I tried using both and ei@% with workbench, but i get access denied error .

Please go to the XAMPP Shell Command Line and run this Query : SELECT USER(),CURRENT_USER(); and post the results of the query in the question. – RolandoMySQLDBA Dec 27 '12 at 21:53
Added result to the question. – Ruchit Rami Dec 28 '12 at 4:12
Have you tried using ei as the username in the Workbench config of the connection? – ypercubeᵀᴹ Dec 29 '12 at 13:18
@ypercube Yes I have tried that also. – Ruchit Rami Dec 29 '12 at 15:25

If you have instantiated a MySQL RDS Instance, you want to create a DB Security Group

  • First Create a DB Security Group
  • Under "Security Group Details", set one of the following connection types
    • CIDR/IP
    • EC2 Security Group
  • Assign Address/Mask
  • Make sure you do not have a proxy/firewall causing interference

I have already done that and i am able to connect to RDS instance with my local shell command line. But can't connect with workbench. – Ruchit Rami Dec 29 '12 at 3:52

Mine is working perfect on MySQL workbench. I remember following these steps mentioned on this link, maybe it helps:
