ı try conncet my sql database on amazon aws
mysql -h database-2.csgofm1hhtui.eu-central-1.rds.amazonaws.com -P 3306 -u ismail -p
But i recieve this exception
ERROR 2002 (HY000): Can't connect to server on 'database-2.csgofm1hhtui.eu-central-1.rds.amazonaws.com' (10060)
Maybe a stupid question, but have you opened inbound Security Group rules?
This error is a result of the inbound connection rule set on your DB instance.
In AWS RDS console, under 'Databases', click on the 'DB Identifier' of your RDS instance. Then in the 'Security group rules' section, click on 'Inbound' type security group and edit the inbound rule to allow appropriate inbound connections.
IF you are trying to connect from an EC2 instance, then the Inbound connection can be the security group of your EC2 instance on port 3306.
See point 4 in the following link :
Create a VPC security group for a private DB instance
If its not Security Group, then it could be a route table issue.

After creating 2 security groups and a RDC instance, I am in the terminal and when I tried to connect to mysql using the displayed endpoint with admin password it is giving '110 can not connect'. can you please guide me with possible reason why this is not getting connected? Image of error message is also attached.
It appears that you have:
An Amazon RDS MySQL database
An Amazon EC2 instance
Assuming that both resources are in the same VPC, the security setup should be:
A Security Group on the EC2 instance (EC2-SG) that permits inbound access on port 3389 (RDP) so that you can login to the instance, with Outbound rules set to their default "Allow All" setting
A Security Group on the RDS database (DB-SG) that permits inbound access on port 3306 (MySQL) from EC2-SG
That is, DB-SG should directly reference EC2-SG.
When connecting, if it takes several seconds before the connection fails, it is an indication that there is no network connectivity. If it fails immediately, then you have successfully communicated with the RDS database, but it is not permitting your access.
I have an AWS Security group that I use for my RDS Instances.
I also have an AWS Security group that I use for my EC2 Instances.
I have it set up so the security group for the EC2 instances is used as Ingress for the security group I use for the RDS instances.
From my EC2 instances, I can use mysql commands to access the RDS instances without a problem.
However, if I try to use a PHP Script with MySQLi to access the RDS instance, it fails to connect.
If I add the actual AWS IP address of the EC2 instance as Ingress to the RDS Security group, then the PHP script using MySQLi works fine.
Any idea why this is the case?
More details:
Both RDS and EC2 security groups are on the same VPC.
Software is connecting fine when the EC2 private address is added with no other changes.
This is why the behavior is puzzling
The typical security configuration would be:
A Security Group on the Amazon EC2 instance (App-SG) with desired Inbound permissions and default 'Allow All' Outbound permissions
A Security Group on the Amazon RDS database (DB-SG) that permits inbound access on port 3306 (MySQL) from App-SG
That is, the DB-SG specifically references App-SG in its Inbound rules.
The software on the EC2 instance should refer to the RDS database via its DNS Name, which will resolve to a private IP address (assuming that the EC2 instance and RDS database are in the same VPC).
If your configuration works with the mysql command on the EC2 instance, then it should also work for MySQLi access since they would both be connecting to the same destination DNS name on the same port (3306).
i have create a aws ubuntu ec2 instance and gives elastic IP. and it's connect on ssh and FTP. but after half an hour it was disconnected and not connecting until now.
i have check add ssh with 22 port in security group inbound rules, also VPC is connect to subnet.
also add 0.0.0.0/0 with target internet getway in subnet Route table, subnet Network ACL has also allow All traffic in inbound rules and outbound rules. and IAM user has only s3 bucket policies.
on the other hand i`m able to connect the RDS mysql database.
Ok, I have an application on ElasticBeanstalk and have setup an EC2 server for my database.
I've been trying to limit the connections to the database to my IP and that of the applications (EB), however all configurations I have tried have not worked.
I have tried using the security group ID - where on the security group ID used by the App had a outgoing connection to the DB and the DB security group had an incoming connection from the security group ID from the App.
Unfortunately that didn't work. And I don't know how to find the CIDR for the EB environment.
Any ideas?
Add the security group on ec2 server to allow the traffic from your home IP and elasticbeanstalk appliaction static IP.
you can find the Elasticbeanstalk application static IP from Ec2 console Or you can use the following command using amazon cli.
aws ec2 describe-instances --instance-ids <instance-id>
I created a windows machine on AWS EC2, and I wanted that only I should be able to connect from my MAC to it, using remote desktop client.
Inbound Rule is used for incoming traffic and outbound rule is used for outgoing traffic.
Since I wanted to connect using Remote Desktop, in the inbound rule of security group I selected "RDP" and then in the source I selected 'My Ip' and thus I secured my ec2 instance such that only I can access it
We are using several EC2-Classic servers (Linux Ubuntu) with following configuration: mounted EBS volumes and on them is running Server version: 5.5.48-MariaDB
I would like to use AWS DMS (AWS Database Migration Service) and to migrate our EBS DBs to the RDS AuroraDB in new VPC.
I created VPC, AuroraDB (not public accessible), AWS DMS replication instance and endpoints.
From EC2-classic instance I am able to open remote AuroraDB console (thanks to Classic Link), which is in the VPC.
Target endpoint (to the AuroraDB) works OK and TEST was finished successful
Source Endpoint show me following error:
Operation:testEndpointDetails:[errType=ERROR_RESPONSE,
status=122502, errMessage=Cannot connect to ODBC provider 122502 ODBC general error.,
errDetails= RetCode: SQL_ERROR SqlState: HY000 NativeError: 2003 Message: unixODBCMySQL http://ODBC 5.3(w)
DriverCan't connect to MySQL server on 'Private.DNS.name' (110) http://122502] ODBC general error.
I tried to set like Server name
Private/Public DNS, and Private/Public IP, still same.
Credentials are OK, and I am not using any special characters.
I am operate in North Virginia Region.
AWS DMS replication instance is set as Public.
I am able to log into MariaDB console from remote EC2-classic instance.
I tried set port 3306 and Private/Public IP of AWS DMS replication instance into right Security Groups, but I guess that I still miss something, probably in the SG area, but I am not sure.
I had the same issue with the same error message and it was a network issue. My replication instance didn't have access to the database.
My database is in a VPC with a subnet x and my replication instance is in the same VPC with the same subnet x. I opened the 3306 port in my Network ACL and in the security group of the database to the Internet (0.0.0.0/0) just to test if it was a network problem. The connection test worked with those settings. After the test, I removed the last setting for security.
The solution to my problem was to open the 3306 port in the security group and in the network ACL of the database to all the vpc connection. e.g. 172.0.0.0/16.
Hope it helps
You must add the security group from your DMS replication instance to your RDS database associated security group as an authorised inbound traffic.
Go to Database Migration Service dashboard and them to "Replication Instances"
Select your replication instance to get the "VPC Security Group"
