I have an existing RDS instance running mysql inside a VPC
It is (was all along) associated with the public subnets of the VPC
The public subnets all share one "public" route table that has a Internet Gateway (IGW) attached (they are explicitly attached to this route table)
It was not originally, but now is set to be publicly accessible
It has a Security group which allows access from outside and I tried both wide open and specific IP here.
Yet still when I attempt to connect the connection just times out ...
$ mysql -usomeuser -h somename.us-east-1.rds.amazonaws.com
ERROR 2003 (HY000): Can't connect to MySQL server on 'somename.us-east-1.rds.amazonaws.com' (60)
What am I missing? anyone ... ?
Assuming that your RDS instance is truly public:
Is in a subnet with an internet gateway
Using a security group that is appropriately open to the internet
Your RDS instance needs to have it's "Publicly Accessible" setting to set to Yes/True. If it is No/False, then resolving your DNS entry of somename.us-east-1.rds.amazonaws.com will result in it's private IP address, which will not work from the outside world.

I have a EC2 Box running in a private subnet. I installed mysql56-server as per: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/install-LAMP.html (I did not install anything else just mysql).
I also have a development website running in a public subnet.
My issue seems to be that I can not connect to this private instance running mysql. Error 1130.
For now, on the private instance(running mysql) I opened up all ports and all ips. (just for testing)
Is there anyway to allow my internal ip connect to this server?
Thanks!
This is not 100% clear from the documents, and I am not sure if there is any serious security implications from doing this.
First you need to create a new root#someipaddress. You can use % as a wild card.
As for me ... I just did the following per my setup:
CREATE USER 'root'#'11.0.1.%' IDENTIFIED BY 'somepassword';
GRANT ALL PRIVILEGES ON *.* TO 'root'#'11.0.1.%';
Howevever, I am on a private subnet, that doesnt not allow any direct connections (only from a development server that is public facing, and that is SGed to only me).
One is on a private subnet vs. the other on a public subnet. You can’t connect the two without a port forward from a private to the public and vice-a-versa. If you can’t ping one from the other, it won’t work. Need a load balancer with port forwarding or another machine on the public to forward to the private, like Apache forwarding.
In AWS, I set up an RDS which was originally not publicly available. I set it up using this tuturial. The Apache server that resulted is publicly accessible; the MySQL instance is not.
Now I'm trying to modify access to the RDS to make it where I can get to it with HeidiSQL.
I've added the RDS to the public security group, and tried a few other mods to no effect.
I'd like make this where it can be accessed only from my IP. But in an attempt to just get a connection, I've set it right now where the security group has it wide open. However, when I try to connect from HeidiSQL or Telnet using port 3306, no TCP connection is established.
Here is the configuration. Any idea what I'm missing?
VPC:
Subnet:
Gateway:
RouteTable:
Security Group:
DB Security Group:
RDS:
RDS instance was inside private subnet and that was the reason Apache (inside VPC) was able to connect to it but you were not able to connect from outside. If you change the private subnet route table to make it public by pointing to 0.0.0.0/0 > IGW - it worked.
To make it only accessible from your machine, you need to go to the attached security group and change the TCP 3306 source from open to all to My-IP.
I am not able to figure out hostname of my MySQL database which is installed on AWS T2 micro server.
I can connect via phpmyadmin. And connecting via PHP code as localhost works ok too.
However can't find hostname or ip which is needed to connect it from service hosted on other server (where localhost won't be an option)
Tried running following
SELECT variable_value FROM global_variables WHERE variable_name = 'hostname'
However the output is ip-172-31-23-11. This doesn't work as hostname when I try to connect.
The output from SELECT variable_value FROM global_variables WHERE variable_name = 'hostname' is showing you the non fully qualified private DNS name.
This should be fine to connect to this instance from the same VPC but if you need to connect from outside of the VPC then instead you should use the public DNS. This, as with the private DNS, is shown in the EC2 dashboard under the instance details (and elsewhere).
As an example:
You then also need to consider network controls such as VPC ACLs and Security Groups. Make sure the security group of your instance allows access from the originating IP over 3306 (default MySQL port).
You'll also want to check the bind-address in /etc/my.cnf to either allow connections specifically from certain addresses as well as localhost/127.0.0.1 or simply remove or comment out the line to allow MySQL to listen to all incoming traffic.
If the application you're trying to connect to the DB with lives on another server, you'll need to get either the public DNS, public IP address, or create an entry in DNS (Route53) that points "database.example.com" into your public IP/DNS name. You can then use one of those as the connection string within the app.
depending on settings, you may also have to follow some of the instructions here.
you might need to bind mysql to listen on the hosts network interface in order to get outside connectivity.
I suggest using telnet to figure that out. if you can't connect (via the command: "telnet 54.4.54.4 5432" (where 54.4.54.4 is your public ip/DNS/route53 entered hostname) then you need to check your security group as well and make sure port 5432 is open to connections from where you're trying to telnet from.
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 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.
