I created a Cluster and an Instance of DocumentDB in amazon. When I try to connect to my Local SSH (MacOS) it displays the following message:
When I try for the MongoDB Compass Community:
mongodb://Mobify:<My-Password>#docdb-2019-04-07-23-28-45.cluster-cmffegva7sne.us-east-2.docdb.amazonaws.com:27017/?ssl=true&ssl_ca_certs=rds-combined-ca-bundle.pem&replicaSet=rs0
It loads many minutes and in the end it has this result:
After solving this problem, I would like to know if it is possible to connect a cluster of documentDB to an instance in another zone of availability ... I have my DocumentDB in Ohio and I have an EC2 in São Paulo ... is it possible?
Amazon DocumentDB clusters are deployed in a VPC to provide strong network isolation from the Internet. To connect to your cluster from outside of the VPC, please see the following: https://docs.aws.amazon.com/documentdb/latest/developerguide/connect-from-outside-a-vpc.html
AWS document DB is hosted on a VPC (virtual private cloud) which has its own specific subnets and security groups; basically, anything that resides in a VPC is not publicly accessible.
Document DB is deployed in a VPC. In order to access it, you need to create an EC2 instance or AWS Could9.
Let's access it from the EC2 instance and access AWS document DB using SSH tunneling.
Create an EC2 instance (preferably ubuntu) of any configuration and select the same VPC in which your document DB cluster is hosted.
After the EC2 is completely initialized, start an SSH tunnel and bind the local port # 27017 with document DB cluster host # 27017.
ssh -i "<ec2-private-key>" -L 27017:docdb-2019-04-07-23-28-45.cluster-cmffegva7sne.us-east-2.docdb.amazonaws.com:27017 ubuntu#<ec2-host> -N
Now your localhost is tunneled to ec2 on port 27017. Connect from mongosh or mongo, enter your cluster password and you will be logged in and execute any queries.
mongosh --sslAllowInvalidHostnames --ssl --sslCAFile rds-combined-ca-bundle.pem --username Mobify --password
Note: SSL will be deprecated. Use tls, just replace SSL with tls in the above command.

I created an Elastic Beanstalk environment from Visual Studio and need to login to service the underlying ec2 vm.
I don't have an credentials for the server, so I wanted to use EC2 Instance Connect.
When I click connect, I get an error message:
We were unable to connect to your instance. Make sure that your instance’s network settings are configured correctly for EC2 Instance Connect. For more information, see Task 1: Configure network access to an instance.
Following the link, I found the instructions:
Ensure that the security group associated with your instance allows inbound SSH traffic on port 22 from your IP address or from your network.
(Amazon EC2 console browser-based client) We recommend that your instance allows inbound SSH traffic from the recommended IP block published for the service. Use the EC2_INSTANCE_CONNECT filter for the service parameter to get the IP address ranges in the EC2 Instance Connect subset.
How do I connect to the Elastic Beanstalk underlying EC2 via EC2 Instance Connect?
What I've tried:
I created a new security group that contains my client IP address, but that didn't work. Which makes sense, as it's the EC2 Instance Connect app running in the Console making the SSH connection, not my local machine.
Also looked at the the ip ranges json file (https://ip-ranges.amazonaws.com/ip-ranges.json), but not sure what to do with that.
I misunderstood the Set up EC2 Instance Connect instructions. This support article had clearer instructions: https://aws.amazon.com/premiumsupport/knowledge-center/ec2-instance-connect-troubleshooting/
Browser-based SSH connections require that your instance's security group inbound rules allow EC2 Instance Connect access to SSH on TCP port 22.
The key was to find the IP for EC2 Instance Connect and then create
a security group to whitelist that ip address.
EC2 Instance Connect IP can be retrieved via PowerShell by using Get-AWSPublicIpAddressRange (or curl). For us-west-2:
> Get-AWSPublicIpAddressRange -Region us-west-2 -ServiceKey EC2_INSTANCE_CONNECT | select IpPrefix
IpPrefix
--------
18.237.140.160/29
Once I configured my Security Group to use that Source I could connect.
Generally better way then using EC2 Instance Connect is through SSM System Manager. It does not require opening any inbound ports. Instead you should add/modify your install role to allow SSM to work. What's more you can control access to your instance using regular IAM permissions, unlike for EC2 Instance Connect.
Connection through SSM is in the same menu in the AWS console as EC2 Instance Connect. Thus, once you setup your instance role, wait few minutes for the instance to register with SSM, and once this happens you should be able to use SSM System Manager to connect to your instance from the console.
Regarding EC2 Instance Connect IP range. I don't know which range published applies only to EC2 Instance Connect. You would have to filter it by region probably and then find one which works. In worse case scenario its try-and-see approach.
Yesterday AWS launched Aurora serverless for PostgreSQL, but it doesn't seem to have the same configuration options as other RDS databases, I can't set it to public facing for example, it forces me to have a VPC.
Now, I have no clue how to apply these VPC things to PgAdmin, I've tried setting the inbound for the security group to all ports and ips but it still won't connect (no server response).
How can I connect to a RDS Database inside a VPC using PgAdmin?
Opening the security group didn't work.
I realize this question is old, but I kept coming back to it as I worked this out.
This solution is similar to #genkilabs solution but simpler.
Steps:
Spin up an ec2 micro instance in the same vpc as the database. You will tunnel through this.
Add the security group for your ec2 to the inbound rules of the database's security group.
ssh into the ec2 instance and install psql (and postgress...) with:
sudo amazon-linux-extras install postgresql10
Verify that you can connect to your database with psql:
psql -h {server} -p 5432 -U {database username} -d {database name} -p
In PGAdmin create a new server connection
Enter the database host, username, and password as usual.
Go to the SSH Tunnel tab
turn on ssh tunneling
enter your ec2 hostname for the tunnel host
enter your ssh username
select the identity file and find the .pem or .cer file for your ec2 instance.
Save and done. You should now be able to connect to the serverless Aurora database from your local PGAdmin.
If you have trouble connecting to the database form the ec2, this guide may be helpful. The same steps apply connecting from ec2 as from cloud9.
EDIT Sept '22: With Serverless V2 you can now select "public access" during the initial create, and connect directly (provided your VPC and security groups allow it). However, it is still recommended for production / "enterprise" use to still connect only though a "bastion" or "jump-box".
Officially, you can't...
Per the docs:
You can't give an Aurora Serverless DB cluster a public IP address. You can access an Aurora Serverless DB cluster only from within a virtual private cloud (VPC) based on the Amazon VPC service.
However, connecting to a serverless DB from a non-Amazon product is just officially discouraged, it is not impossible.
The best solution I have found so far is to create an autoscaling cluster of bastion boxes within the same VPC. Then use them to tunnel through. The great part about this strategy is that it exposes a standard postgre format URL, so it can be used with pgAdmin, Navicat, ActiveRecord or any other ORM that uses typical connection urls.
...The bad part is that (so far) it seems to enforce a 30 sec timeout on connections. So you better get all your transactions wrapped up quick like.
If anyone can do better, I'd love to hear how as well.
I can't connect to my Amazon DocumentDB from my amazon EC2 ubuntu machine? I've checked the security of the Amazon DocumentDB and it's currently assigned to the default which has "all traffic".
I've tried the following command, straight out of the AWS instances page although I receive the error message included below.
I've followed this aws guide https://docs.aws.amazon.com/documentdb/latest/developerguide/getting-started.connect.html

Am I doing something wrong? Any help appreciated!
Many thanks,

Amazon DocumentDB deploys clusters within a VPC, which act as a strong network boundary to other VPCs and the Internet. When you are connecting to your cluster, ensure that the client machine is in the same region and the same VPC as the cluster.
Alternatively, if your development environment is in a different Amazon VPC, you can also use VPC Peering and connect to your Amazon DocumentDB cluster from another Amazon VPC in the same region or a different region.
For more information on troubleshooting: https://docs.aws.amazon.com/documentdb/latest/developerguide/troubleshooting.html
Connecting to an Amazon DocumentDB cluster from outside a VPC: https://docs.aws.amazon.com/documentdb/latest/developerguide/connect-from-outside-a-vpc.html
Had the same problem.
Availability Zone/VPC/Security Groups are the same for
EC2 instance and DocumentDB instance, but still failed to connect.
For some reason, the US documentation is missing one step that is present in CN documentation.
https://docs.amazonaws.cn/en_us/documentdb/latest/developerguide/connect-ec2.html
All you need to do is to add another inbound rule to the Secutity Group for TCP and 27017 port. This worked for me.

I have created a redis endpoint on amazon elastic cache and also setup vpc & NAT gateway. I need to connect created redis endpoint with redis-cli. i using command like this
redis-cli -h dev-redis.434dffsdsf.0094.ustyue1.cache.amazonaws.com
But i got error message like this
Could not connect to Redis at dev-redis.a35gy4.0001.use1.cache.amazonaws.com:6379: Connection timed out
I tried with several ways
tried to connect from my local ubuntu machine.
tried to connect from a ec2 instance.
My source code is running on aws lambda. Using aws lambda we can successfully connect to the same redis endpoint.
What is the actual issue with my redis client?
Please check SG of ElastiCache. Redis instance should be accessible to server where you're running Redis CLI.
Option 1 will not work, as ElastiCache instances are not accessible outside of their VPC. From the FAQs: "Amazon ElastiCache Nodes, deployed within a VPC, can never be accessed from the Internet or from EC2 Instances outside the VPC."
Option 2 should work, if the EC2 instance is within the same VPC as the ElastiCache instance.
Adding more details as none of the answers here gave me full clarity
What is security group - security group in AWS is like a firewall.
What should I check in the security group - Check in inbound rules of the security group attached to the Redis if port 6379 is open to IPs within the CIDR (e.g. 192.168.32.0/20) of the EC2 instance from which you tried to access the Redis/ElasticCache
I am quite new to Elastic Beanstalk and not very proficient with server administration, but I need to set up a Django project on Elastic Beanstalk connecting to external RDS MySQL database.
I have created a separate RDS MySQL database and I can connect to it using Sequel Pro on my computer without problems. Then I have my Django project which I try to put to Elastic Beanstalk, but unfortunately without luck. If I run the local Django server from my computer, the project is browsable and Amazon RDS MySQL is accessible. However, when I run
eb deploy
I get
django.db.utils.OperationalError: (2003, "Can't connect to MySQL server
on 'myapp-staging.xxx.eu-west-1.rds.amazonaws.com' (110)")
(ElasticBeanstalk::ExternalInvocationError)
If I login to the EC2 server via SSH
eb ssh
and then check the open ports with
netstat -lntu
I don't see MySQL's port 3306 there, so I guess it is blocked by firewall.
This is what I tried regarding permissions:
I went to RDS Dashboard -> Security Groups and created myapp-mysql-security-group with EC2 Security Group connection type pointing to EC2 security group used by Elastic Beanstalk EC2 instance “awseb-e-...”.
I went to EC2 -> Security Groups and for “awseb-e-...” I set the Inbound MySQL port with source 0.0.0.0/0
I went to VPC Dashboard -> Security Groups and created myapp-mysql-security-group with Inbound Rules of MySQL port with source 0.0.0.0/0.
Then I tried to redeploy, restart servers and even rebuild environment, but nothing helped. The MySQL port 3306 is still not open in the EC2 instances created by Elastic Beanstalk.
What am I doing wrong or what is missing?
MySQL port 3306 is only opened at the RDS instance (not in your EC2 instance). So, if you check on your EC2 instance, it should not listen on port 3306.
Things those you can do to check RDS is working:
Check your EC2 instance connection to RDS.
SSH to your instance (eb ssh) and run telnet myapp-staging.xxx.eu-west-1.rds.amazonaws.com 3306. You might need to install telnet first (yum install telnet).
If it's success, check your app.
If it's failed, check on next point.
Make sure your RDS and EC2 placement is correct:
For private only access RDS:
Make sure they are in same VPC and allow incoming connection in RDS from VPC's IP to 3306. For better performance, use IP address instead of Security Group name.
If they are on different VPC, you can create VPC Peering.
For public access RDS:
Same as above, allow incoming connection from VPC's IP.
Make sure EC2 instances are allowed to make outgoing connection to port 3306 in EC2 security group.
Make sure your EC2 host doesn't have denied 3306 rule in iptables.
If your EC2 and RDS in different VPC and you use private IP for your EC2, check the NAT server. Make sure you allow port 3306 to be proxified.
