I am new to AWS , I can access EC2 user by putty. Like this how can i connect AWS RDS by PUTTY ?
I have AWS RDS Endpoint , If i try like the below
mysql -h testing.cx2wamr3cbzm.us-west-2.rds.amazonaws.com -P 3306 -u Username -p
I am getting some error like
ERROR 2003 (HY000): Can't connect to MySQL server on 'testing.cx2wamr3cbzm.us-west-2.rds.amazonaws.com' (110)
I think there is a problem with security group.I searched more, but its difficult to understand for me.
I want to create database and assign rights ?
Thanks
RDS is not available to the world by default. It's also generally a bad idea to allow access to the RDS from anywhere except from inside your VPC. I recommend you do the following:
Create a security group that allows access to the RDS over port 3306 from your EC2 instance
Visit https://console.aws.amazon.com/ec2/home#s=SecurityGroups and create a new security group.
Switch to the inbound tab and choose MYSQL from the dropdown.
Erase the 0.0.0.0/0 in the source field then click the input field. It will present you with a list of existing security groups. Choose the one that your EC2 instance belongs to.
Click the apply rule changes button
Assign the security group to your RDS
Visit https://console.aws.amazon.com/rds/home#dbinstances: and select your RDS instance and under the Instance Actions menu select Modify
Change the RDS security group to the one you just created
Make sure to select the Apply immediately option at the bottom of this page
Click Continue and apply the new changes. (the change can sometimes take a couple of minutes)
SSH into your EC2 instance then run the mysql command in your question

I followed all the steps mentioned on here
to connect to Redshift through Workbench J.
I am not using SSH to connect, so have left SSH settings alone.
When I select Security after selecting Redshift, I see :
Your account does not support the EC2-Classic Platform in this region. Cluster Security Groups are only available when the EC2-Classic Platform is supported. Instead, use VPC Security Groups to control access to your clusters. Go to the EC2 Console to view your VPC Security Groups. For more information, see Amazon Redshift Documentation on Supported Platforms and Managing Clusters in VPC.
My cluster is under a Security Group which has the following Inbound rule :
Type: Redshift
Protocol: TCP
Port Range: 5439
Source: Custom 0.0.0.0/0 (Experimental, just to test,
I will replace this with my IP address)
When I do a Netstat on the host from my machine with -Pn. I get a
Host is up.
PORT STATE SERVICE
5439/tcp filtered unknown
Nmap done: 1 IP address (1 host up) scanned in 2.22 seconds
I have already gone through several similar questions and none of these is working for me.
Double check your Security Group settings:
In the Redshift console, go to the Configuration tab.
Click on the link next to VPC security groups
Should take you to Security Groups in the EC2 console with the correct security group selected.
Select the Inbound tab for the security group and click the Edit button (a dialog box opens).
In the dialog box, click the Add Rule button then:
Select Redshift from the Type dropdown menu
Select Anywhere from the Source dropdown menu
Come back and change this to My Ip once your connection works!
Click the Save button (the dialog closes)
You now have 2 new Redshift rules (0.0.0.0/0 AND ::/0)
Then in SQL Workbench's "Select Connection Profile" dialog:
Click "Manage Drivers" at the bottom left and to add the Redshift JDBC driver.
SQL Workbench configures these automatically but check that Classname is like com.amazon.redshift.jdbc42.Driver and Sample URL is jdbc:redshift://host:port/name_of_database.
Next, configure the connection
Select the new Driver you just created from the drop down.
Copy the JDBC URL from the Redshift console Configuration tab and paste it into the URL field.
Must use the correct port: jdbc:redshift://my-cluster.asdfgh5jk8.us-east-1.redshift.amazonaws.com:5439/my-db
Add your Username and Password
Test the connection! (Bottom right)
Please let me know in the comments if this doesn't work for some reason and I'll help you get it working.
It's my first time using an ec2 instance from the spot market. I'm assuming its the same to SSH into as with any normal instance. I submitted a request and got one back but now for some reason when I try to SSH into with the public IP I'm getting a timed out error. Is there anything else I need to do after submitting the Spot request, other than waiting for someone to fill it?
As many other users have commented, there are two things need to be done for ssh
assign an aws key-pair when launching the instance
assign a security group with ssh permission
To check whether these two conditions are met for your instance, you can go to the aws EC2 Management console, click on your instance at the instance tab, and check if there is a Key pair name associated with it, and whether the Security groups inbound rule contains port 22 tcp protocol.
If you launch with boto3, the command will look like this
rc = ec2.create_instances(ImageId=ubuntu_64bit,
InstanceType='t2.nano',
MinCount=1,
MaxCount=n_workers,
KeyName='my-key',
)
Here I used the default security group and I have added ssh permission to it.
When these conditions are met, you can log on to the instance using
ssh -i /path/my-key-pair.pem ec2-user#ec2-198-51-100-1.compute-1.amazonaws.com
Depending on the image you load, the user name could vary. Possible ones include ec2-user, centos, ubuntu, root.
Timeout error for ssh means port 22 on this spot instance isn't open to you. Check the security group and add your location IP, allowing access to port 22
I'm new to Amazonaws. created a Mysql DB instance on RDS. with a free account.
Now when trying to connect from local machine by MySqlWorkbench.
below is the endpoint of my db instance
XXXXXXXXXX.XXXXX.us-west-2.rds.amazonaws.com:3306
using the same as above as hostname and port on local still not able to connect.
Does it has anything to do with the region? I mistakenly selected Oregon(west) region whereas I'm in New Jersey(east)
There are two primary solution candidates.
Firewall
Go into VPC Security Groups (I guess that is where you control the firewall. My paid account uses Security Groups). Ensure that your public IP (and only your public IP) is allowed through the firewall.
MySQL Permissions
On the local machine, check that your remote machine is allowed to connect. It's also possible that MySQL is not running. You'll discover if that is the case while checking permissions locally.
Thanks a lot guys, Following are the steps to correct.
Go to MySQL instance. ]
click on security Icon.
Click on security Group
at bottom click on Inbound
Click Edit
Add your IP for MYSQL db or any DB instance you have.
I am new to AWS. I set up an instance and deployed a Django App on it by following this tutorial
But when I try to access the instance from the browser via the ip or the public DNS it returns 'No data received', 'ERR_EMPTY_RESPONSE'. Any idea where I am going wrong?
Here are the steps I followed to solve this:
Went to EC2 instances
Click on instance
Go to Security Groups column and click on the security group selected.
In the lower panel, select Inbound > Edit > Add Rule
Under Add Rule, select Type as HTTP and Save.
Am following this tutorial

I am not able to Test DB Connection while creating new server instance to connect to the RDS database.
It says Bad_Authentication[allowed_types=public_key], i have a tried different .pem files and have done through a lot of forums.
I have also allowed access to my IP in the DB SecurityGroups for RDS and the Security Groups for EC2.
Please help me out. Thanks.
This worked for me. Assuming you have logged into AWS:
Go to RDS -> Databases -> Select your database
Make sure the Public Accessibility value is Yes
Check your IP address using http://checkip.amazonaws.com/. If it is not added to the Security Rule Groups, you should add it. this step is crucial
3.1. Click on the rule name. This will open up a new tab, then click in the name of the rule.
3.2. Click on Edit inbound rules
3.3. Click on Add new rule, and add a rule with the following values:
Type: MYSQL/Aurora.
Protocol: TCP (default)
Port range: 3306 (default)
Source: My IP -> This will be the IP Address you got at http://checkip.amazonaws.com/.
Fill information in MySQL Workbench
Hostname: Use the value you have for Endpoint at Connectivity and Security
Port: Use the value you have for Port at Connectivity and Security, by default it is 3306.
Username: Use the value you have for master username at Configuration
Password: Use the value you set when you created the database instance.
If you forgot the password, you can change it by clicking on Modify in your database instance)
I hope this also helps you.
In my scenario the problem was simple
I had to enable 3306 port for MYSQL in the related Security group in RDS > db instance section.
For RDS no need to use ssh. You can directly connect the RDS with MySql workbench.
Follow the following steps-
Make sure that in Security Group you should have provide access for MYSQL
Open MySQL workbench and setup New Connection.
Provide a Connection Name.
Connection Method is set to Standard (TCP/IP)
In the HostName provide your RDS end point
Port is 3306
Enter the username what you have given in the RDS.
Test Connection, and provide the password.
That's it.

If you are not using EC2 Instance to connect with RDS DB Instance then DB Instance should have public access to connect.
While launching DB Instance you need to set Publicly Accessible to yes. You will get Public IP to connect from outside network. That means outside of VPC.
You need to launch DB Instance in Public Subnet which has directly access to Internet. To check Subnet has Internet access, you need to check Route Table which was attached with the subnet. In Route table, check Internet Gateway is attached to the subnet.
You don't need to SSH into DB Instance. Though the option is not available also.
In MySQL WorkBench, click on Setup New Connection.
Give connection name. Choose Standard (TCP/IP) option. You are not trying to connect DB Instance over EC2 Instance so the option with SSH with not work out in this case. You have to provide MySQL hostname, username, password and port.
To verify connection, click on Test Connection button.
If you want to use EC2 Instance and connect DB Instance over EC2 Instance, you have to use Standard (TCP/IP) over SSH option. Check the following link
What would prevent me from connecting to a MySQL server on AWS RDS from an AWS EC2 VM?
I had the same issue. I think you need to enable inbound traffic to the VPC. Follow the below article and you'll be fine. Default VPC is not allowing users to access 3306 by default and you need to allow traffic.
RDS and MySQL Connectivity
Make sure Public accessibility should be yes.
Also, Inside security Group section, click on the security link and then add a new rule under inbound rule section which will whitelist your IP address with the below data :
Type: MYSQL/Aurora.
Protocol: TCP (default)
Port range: 3306 (default)
Source: My IP -> This will be the IP Address you got at http://checkip.amazonaws.com/.
Hope this will help to connect with AWS RDS successfully. Thanks!
Based on the details in your question, it seems that you are trying to SSH into the RDS instance. This is not supported on RDS, it only works for EC2 based MySQL servers.
You should instead connect directly to the MySQL server, on port 3306 (or the one you set manually, if this is the case) and using the username and password you created when provisioning the RDS instance. This means using the Connection Type "Standard TCP/IP" in WB.
Also, the public IP address of the machine you're using MySQL Workbench on should be allowed in the RDS security group.
Even I had the same issue, like after trying all the things out there. A thing worked is modifying the RDS database and making it publically accessible. That sorted things out.
All of the other answers are extremely helpful to debug the connection process but for me the literal fix was to not put in the password into the keychain when initializing the MySQL Connections. Instead, I pressed Test and put in the password when prompted to do so. Running on macOS Monterey V.12.3.1 with a MBP M1, 2020
