I went through these instructions:
http://docs.amazonwebservices.com/AmazonRDS/latest/GettingStartedGuide/
But still can't connect to the database using mysql from the command line.
I even tried:
telnet xxxxxxx.clpkcufglfdn.us-east-1.rds.amazonaws.com 3306
but that doesn't connect either.
I did set up the DB security group using the CIDR suggested by the console (I hope it give me the right value).
Update: Firewalls are disabled on my end. It would be odd if amazon had firewalls on their end and wouldn't mention it in their documentation.
Update2: I'm behind a wireless router which had assigned my machine the IP of 10.0.0.2 so I tried adding that to the security groups but still can't connect.
Update: Firewalls are disabled on my end. It would be odd if amazon had firewalls on their end and wouldn't mention it in their documentation.
Amazon's security groups are a firewall.

If it's not the IP you're connecting from, it's not the right value.
Sounds like you have a firewall that is dropping your connection. Either it is on your end or Amazon's end; probably need to talk to your IT group and if that isn't the issue then Amazon's group to see if you missed a step.
If you are trying to access a RDS instance from within the same AWS datacenter you need to specify a local internal IP address (i.e. 10.x.x.x) and not the public dns/ip as your connection simply doesn't go out of the lan
You can find the local IP address of your EC2 box by typing: ifconfig OR checking your login name (i.e. ubuntu#10.x.x.x)
I didn't find this anywhere and wasted a lot of time. I hope this helps!

I followed this article to setup mysql server in my aws vm. At the time of creation of the vm itself I had allowed inbound traffic to port 3306 from all ip addresses.
After creating an admin account, I cannot access the account from outside the vm using sql workbench. I made changes in the property file to change the bind-address to 0.0.0.0 so that remote connections maybe allowed from outside. That also did not help.
What am I missing here? I did everything and still it won't connect. Appreciate any help on the matter.
AWS Security Groups
Based on the comments.
The issue was that mysql was setup to allow access from localhost. To solve the problem, external access needed to be allowed. This can be done by following the guide:
How To Allow Remote Access to MySQL
I have no idea how to connect mySQL to amazon EC2 Instance. Here is the screenshot of mySQL workbench: mySQL. I try to change the HostName to the Public IP being provided by the instance, however when i press test connection, it keep promoting this error: Error Message. So what should i do as of now? Thanks!!
Since I cannot put a comment, pardon me for putting this to the

Error 10060 is a generic error that means your client cannot reach the server.
Try pinging your server IP, if it responds, it is online.
Are you sure that the port that EC2 uses is also 3306? Configure your EC2 Instance to allow remote connections. Check the EC2 Security features, something might be blocking you.
AFAIK, the root user is only limited to localhost. So it won't work if you use it remotely. Create a new user with the privileges that you only need, then use the '%' wildcard which means any host.
And finally, you may want to try this: Step by Step instructions
In your EC2 instance you will have a Security Group Column.
Click on that will open the security group page
In the bottom of the page you have a tab called Inbound
Click Edit and then Add Rule to allow port 3306.
In source select anywhere option.
I keep running into this error while connecting to my newly built RDS MySQL instance
ERROR 2003 (HY000): Can't connect to MySQL server on
'****.ap-southeast-1.rds.amazonaws.com' (60)
I wouldn't say I am an expert, as I have several EC2 instances running and able to connect.
And I have all the security groups created and necessary permissions for inbound added accordingly. But i just quite connect to the RDS instance.
1. I have re-recreated with guide from AWS document, created new VPC group and dedicated DB security group.
2. Gone through most of the responses from similar questions, and applied the suggested resolutions (which is adding own public IP in the inbound rules) etc..
Any help?
1)
Make sure that the server is running
telnet ****.ap-southeast-1.rds.amazonaws.com 3306
2) Make sure that the server is not bind to specific address.
bind-address = 127.0.0.1
3) Make sure that the IP address that you have added to security group is correct. Don't forget the /32 for a single ip. You can get IP address from
/sbin/ifconfig
4) Make sure that there are no firewalls on outbound traffic on the host from which you are trying to connect
Does your RDS configured as publicly accessible? If not, you can only connect it within your VPC.
Thanks everybody. I was able to resolve the problem. The supported platform uses the EC2,VPC, so my AWS account is in the current region that does not use a default VPC. I dumped everything out, created VPC using wizard, then the security group. Then re-created the DB instance, assigned it the new VPC i re-created. Thanks for your efforts.
I'm running EC2 with MySQL RDS to serve dynamic websites' content.
The server was down due to 'too many connection' error on RDS database.
As it was urgent, I restart database server straight away and the problem gone.
However, I'm unable to see what queries produce those connection (as I didn't run SHOW PROCESS LISTS before reboot RDS).
CloudWatch show 250+ connections during period of issue which is obviously huge distinction from normal operating on other days.
I try to address the issue by see log in RDS, but there is quite a minimal message there.
The error message
2014-05-03 06:10:08 3628 [Warning] IP address '173.244.206.19' has been resolved to the host name '173.244.206.19.static.midphase.com', which resembles IPv4-address itself.
From above, 173.244.206.19 is not in our IP list both public and private. (but connection open to 0.0.0.0 secured with password which I'm going to limit IP remote in security group soon)
Questions
Is 173.244.206.19.static.midphase.com is something to do with RDS by default. I think this is obviously an attack sign but just would like to confirm.
What does 'resembles IPv4-address itself' mean? As this is RDS database server only, why server does need to resolve DNS?
Are there any way to digging into this for further detail (e.g. to see specific query).
I'm going to prevent this by only limit the IP access along with CloudWatch alarm setting for 10+ connections. Anything else I should do.
Thank you for reading through this guys. I'm the only developer in company start-up which take care for all front-end/backend/application/network. Therefore, apology if there are dummy questions out here.
However, your help would be really appreciated and will save a bit of my life writing the report.
You are maybe the target of a DDOS attack or a brute-force password discovery attempt.
I would report this to AWS support - as they can help to mitigate the effect of the attack.
As a best practice, we do not recommend to use 0.0.0.0/0 as source IP address for incoming connection rule in Security Group.
Try to restrict which IP addresses are authorised to connect to your database.
If you are accessing from on prem network, specify only your on-prem address range.
If you're accessing your database from an app server installed on EC2, use the ID of the App Server Security Group (sg-xxxx) as source authorised to connect to your database.
I'm trying to connect to MySql on Amazon RDS from my computer, using MySql WorkBench, or HeidiSql or even the console Mysql.exe and i'm getting this error all the time:
ERROR 2003 (HY000): Can't connect to MySQL server on 'MY-SERVER-NAME' (10060)
In the Security group of the instance I created a new Inbound rule that allows all traffic, and applied it, and still - same error.
I have no active Firewall on my computer, and have good internet access
I am able to access the DB from the Amazon EC3 server, there I am connecting using HeidiSql, and the exact same settings (host, username, password) is just not working on my computer
Still, nothing is working. I'm pretty sure that my security groups is configured to allow outside connections, as can be seen on the next screenshot, there is another place with firewall rules?
I was having the same problem when using an RDS instance on a VPC that I wanted to connect to remotely. To fix the problem, I needed to do the following:
Go to the VPC Management Console in AWS
Go to Internet Gateways (on the left side)
Create and attach an internet gateway to my VPC. Make note of the ID of this gateway.
Go to Route Tables
Edit the route table associated with the subnets associated with your RDS instance
Add a route:
Destination: 0.0.0.0/0
Target: ID of your Internet Gateway
I didn't have this route in my table because I created my VPC manually and without using the wizard, but if you use the wizard it creates this route for you automatically.
Note: This assumes that your security groups are already configured to allow your IP to connect.
The 2003 error is the Access-Denied Error I would be willing to bet that you haven't configured the RDS to accept your IP address.
This can be done by going to DB Security Groups -> Click Default -> and add a new CIDR/IP range. I believe that if you set it to 0.0.0.0/0 it will accept all ip addresses
I use SQLyog for connecting to Amazon RDS from my machine.

The security group settings are just firewall rules. If you can telnet on your configured MySQL port from the host you are having problems then you don't have the security group issue.
Chances are the MySQL grants are not allowing outside IPs. If you know the root user/password and you can use it to connect from your EC2 instance that works, make sure the user you are using to connect from outside has the right privileges. Here is the doc on how to add a new privilege or create a new user:
http://dev.mysql.com/doc/refman/5.1/en/grant.html
http://dev.mysql.com/doc/refman/5.1/en/adding-users.html
http://dev.mysql.com/doc/refman/5.0/en/access-denied.html
Did you assign the security group to your RDS instance? If you didn't modify the default security group, then you need to add your security group to your RDS instance.
In my case, my company had two different network connections. When I went to google and searched "What is my IP?" I got one answer; 209.x.y.z. When I went to checkip.amazonaws.com I got another answer; 199.a.b.c.
I had already added VPC Security Group Rules for 209.x.y.z and it turned out I needed them for 199.a.b.c.
Adding rules for 199.a.b.c fixed the issue.
I had same problem as you, all firewall have been opened, but still can not access to my RDS mysql remotely from my local machine. my finally workout is there is a "Public Accessibility" option on your RDS database. default is "No", after I tick it to "YES", everything is running smoothly now.
