I am new to AWS RDS. I have created RDS instance.But i dont know, how can i connect this DB.
I tried like this
mysql -h awsinstanamehere.rds.amazonaws.com -P 3306 -u username -p
After i entered password and i am getting some error like this
ERROR 2003 (HY000): Can't connect to MySQL server on
'awsinstanamehere.rds.amazonaws.com' (110)
Need to set any security setting in AWS console?
Note:
I want to import tables for that DB
Thanks
RDS has a security group - in the AWS console, RDS, there's an entry for security groups.
If you didn't explicitly create a security group, you are probably using "default". You should probably have one group per RDS instance.
You will need to make sure that port 3306 is open to your local network, as well as whatever application you will be using to connect to it. You can allow access by IP or by security group.
Same error, but in my case the problem wasn't related to security groups.
I forgot to add an additional route to the route table of the subnets.
See below the 2nd route where the internet gateway was added as the target for all non local traffic (outside the VPC):
I was having a little trouble with these answers so here are the steps I followed to get it working...
Logged in via ssh to my ec2 instance.
typed this command, curl canhazip.com
copied the ip address that was returned
went to my VPC Dashboard in aws
clicked on Security Groups in the left column
clicked on the checkbox next to one of the security groups
clicked Edit under the Inbound Rules tab
added this rule : MySQL/Aurora (3306) TCP (6) 3306 [IP from #2]/32
saved
I did this for every security group until the mysql connection worked from the command line, then deleted all of the ones that I didn't need, and retested to make sure I could still connect.
By default security group defined by AWS is not configured for publicly available inbound source. You will have to modify the security group inbound source ip to 0.0.0.0/0
It worked for me when I added the port 3306, while it was only the 1433 it was not working....
so the security group was created like this
security group vpc-XXXXXX
MY SQL / TCP / 1433 / 0.0.0.0/0
MY SQL / TCP / 1433 / ::/0
MTSQL/Aurora / TCP / 3306 / 0.0.0.0/0
MSSQL/Autora / TCP / 3306 / ::/0
following the headers TYPE / Protocol / Port Range / Source

I have an AWS RDS database I can't connect, I get the following error:
mysql -h rds.eu-west-1.rds.amazonaws.com -P 3306 -u admin
ERROR 2003 (HY000): Can't connect to MySQL server on 'rds.cfckm0d26fsq.eu-west-1.rds.amazonaws.com:3306' (60)
The RDS security group allows all traffic for my IP as well explicit opens 3306
Also I have my RDS as Publicly accessible (which I don't like)
To travelshoot, I also open my security group to the world: 0.0.0.0/0, but the error remains
You needn't keep the security permissions Public.
You can just add the public IP of the inbound traffic to the Security Group for the RDS DB you are using. When you open the RDS DB instance, open the VPC Security Group --> Security Group ID --> Edit Inbound Rules --> Add your IP .
This solved my issue.
As I was on a private subnet, t didn't matter if I opened ports to the world. To trouble shoot I telnet the RDS
telnet rds.eu-west-1.rds.amazonaws.com 3306
And I saw there was no connectivity. So I created an EC2 within the same subnet and from it connected to the RDS.
NOTE: no need to have all traffic open (as I saw on my posts and youtube), just 3306 to private or requesting ip and for port 3306. Also no need to make the RDS public
I have an RDS instance running on one subnet without NAT, and an EC2 instance running on another subnet with an Internet Gateway configured, both located in the same VPC. I have configured the RDS instance to not be publicly accessible.
I am using the following command in my remote EC2 (running on the second subnet) to connect to the RDS instance:
mysql -h xxxx.eu-central-1.rds.amazonaws.com -P 3306 -u root -p
I have entered the correct password which I have set when configuring the RDS, but I get the following error:
Can't connect to MySQL server on xxxx.eu-central-1.rds.amazonaws.com
What am I doing wrong? Am I missing something?
You most likely need to open port 3306 in the security group assigned to the RDS server. In particular, create a rule allowing ingress on port 3306, and for the source use the ID of the security group assigned to the EC2 server.
The Security Group ingress rules for your subnet and/or your PostgreSQL instance must have port 3306 open for PostgreSQL. If you have changed the default port, you must use that port instead.
Your EC2 instance should not have to communicate through the internet to reach it, it just needs the proper port open in the security groups.
If you are not allowing all egress data in your EC2 security group, then you will need to ensure egress port 3306 is open on the EC2 security group, to the RDS security group.
I'm trying to connect to a remote DB with MySQL Workbench over SSH. The remote DB I'm trying to connect to has firewall which is private key protected (I have coverted this to OPEN SHH). I keep getting an error when I try to connect, I'm just a little confused on what is the information of the DB I should be using. I consistently see people use localhost and the DB changed intermittadely at the same point in different questions. My set up is currently that I have to connect to the server of the firewall(check) now there are multiple VMs running I wish to connect to e.g. 192.1.91.0. I have also a port set up to this on putty( I don't know if this is relevant) on localhost 5000. When I try to connect using 192.1.91.0 port 3306 or localhost 5000. I get the same error. Can anyone help. Attached is an image of the information I put into workbench
I think there are a few misunderstandings here. A firewall is not protected by a keypair. An SSH connection is. The firewall only filters network traffic using specific rules (e.g. only let it pass for enabled network ports). When you use an SSH connection you have to use the MySQL address as seen from the remote SSH connection end. That means if the MySQL server runs on the same machine as the SSH server (which is what you connect to when you use an SSH tunnel) then the address is localhost (or the IPv4/IPv6 loopback address). See my video about connection creation and troubleshooting on Youtube for more details.
To connect workbench with a private database you will need a 'jump host' also called 'bastion host' which can be any EC2 instance in a public subne in same VPC as database.
Follow Below Steps:
Open the security group attached to the database, and add new rule as below:-
Type:MYSQL/Aurora, Protocol:TCP, PortRange:3306,
Source:securitygroupofEC2 (you can all security group by entering
'sg-')
Open the security group attached to the EC2, and make port 22 is open. If not, add a new rule as below:-
Type:SSH, Protocol:TCP, PortRange:22, Source:MY IP
Open Workbench, Click New connection
- Standard TCP/IP over SSH
- SSH Hostname : < your EC2 Public IP > #34.3.3.1
- SSH Username : < your username > #common ones are : ubuntu, ec2-user, admin
- SSH KeyFile: < attach your EC2 .pem file>
- MYSQL Hostname: <database endpoint name> #mydb.tbgvsblc6.eu-west-1.rds.amazonaws.com
- MYSQL Port: 3306
- Username : <database username>
- Password: <database password>
Click 'test connection' and boom done!!
If the MySQL Server is configured to accept remote connections, you can use the servers IP address, but then you don't need to connect over ssh. Once you choose connect over ssh, the workbench creates a portforwarding using the ssh credentials to the specified server. So you have to use localhost as MySQL hostname. Due to the portforwarding, the request will be forwarded to your remote machine. In short: As far as I understand your question, you have to use localhost.
I am trying to access my rds mySql db via 443 only instead of 3306.
After enabling the ssl option on workbench and entering the path to the mysql-ssl-ca-cert.pem I tried to disable tcp 3306 on my security group to insure it connects using 443 but it doesn't.
I can connect using the mysql command line below but yet again it fails once i disable tcp 443 on the security group
mysql -h myinstance.c9akciq32.rds-us-east-1.amazonaws.com --ssl_ca=rds-ssl-ca-cert.pem
Amazon documentation states:
The SSL support in Amazon RDS is strictly for encrypting the connection between your client and your DB instance; it should not be relied on for authenticating the server.
Does this mean that I can only ever authenticate to mysql db over 3306 and not 443, but the data will be encrypted in transit?
My issue is that my customer won't open 3306 outbound on their firewall but 443 is of course opened. Any help appreciated.
You are confusing SSL and HTTPS. Port 443 is the default port for HTTPS connections. MySQL uses 3306 instead (and can use SSL over this port or any other to encrypt the connection). So, setting up SSL encryption for a MySQL connection doesn't affect the used port.
In order to use a different than the standard port you have to reconfigure the MySQL server, which you probably cannot do with an RDS instance.
It is possible to use tunneling to avoid the default port. In this scenario you have to open an SSH tunnel (MySQL Workbench can do that for you or you use an external program like putty on Windows or ssh on *nix like OSes). With that tunnel in place (which uses port 22 by default but can be configured for any other port if that matters for you) you can then forward access from a local port (here 3306, but can be any) to a remote port (can be any as well). This requires an SSH server on the remote end however.
I'd like to connect to MySQL (deamon is running on my VPS) via HeidiSQL. I've created new user, commented bind-adress option and when I try to connect with it via HeidiSQL, I've got an error 2003: Can't connect to MySQL server on 'xxx.xxx.xxx.xxx' (10061).
What should I do?
It could be a number of factors.
See if a firewall is blocking your traffic to the other host
Can you simply ping the host from the client machine?
Can you also open a simple telnet session to the host on port 3306 ?
(If the telnet is accepted, you will probably see some characters appear and you will remain in the telnet session for a few seconds before the connection is closed. If not accepted, you will see the message Connection refused.)
There's a simple checklist for this:
Is your MySQL server bound to "localhost" only? It might be listening for connections only on 127.0.0.1 or ::1 instead of any which is usually 0.0.0.0. Try connecting on your server to your server with mysql --host=host_ip where host_ip is your network IP address. I think the default is localhost-only.
Is port 3306 firewalled? Many distributions allow only SSH by default, so you may need to open this up to your client machine. Try not to open this up to everyone on the internet as having an open MySQL port is asking for trouble. It's always best to limit access to a set of specific IPs if possible.
Can you connect via an SSH tunnel instead? This is far more secure as it means your 3306 port is properly firewalled. There are many tools for creating SSH tunnels, but the basic principle is to forward a local port of your choosing to the remote server's port 3306.
