I cannot reach my MySQL Database instance I created on AWS.
What I tried was to set the public access of the Database to "Publicly accessible" here:
Also I tried to set Inbound/Outbound rules for the MySQL port here:
Honestly I think using "All" ports would include 3306 too. Anyways, I tried it this way because yet it didn't work. I cannot connect to the database via MySQL Workbench, nor can I use a ping request on the given endpoint.
I would be glad if someone here has an idea what I could try else.
This will not work if you have deployed it in a private subnet which has no internet access.
Another possibility is that there is ACLs that is stopping the traffic. Security group only touch the RDS instance, the ACLs control traffic in the entire subnet.
Here is a dev AWS tutorial that creates a web application that stores data in MySQL running on the cloud. It will show you how to setup the database and the inbound rules. Once you do, you can store data or query data from MySQL. Likewise, you can use MySQL Workbench to interact with MySQL on the cloud.

After spending hours trying to debug this problem, I've come out empty-handed.
I'm new to AWS, so it's possible I might be missing something here, but it seems I've exhausted all possibilities based on what I've read online.
So the idea is, I want to create a RDS instance. I'm new to cloud computing as a whole, but how I understand it, this instance is essentially the storage of my relational database on the cloud. Then I connect the DBMS of my liking to it on my local machine. I tried with both Postgresql and MySQL, but both ran into the same issue. Note, when I say I used the two aforementioned DB engines, I made sure that in each case, I set them as the engine when creating the RDS instance. I then configured the security group accordingly.
What I've done:
I've created an admin user as per the aws docs.
I created a security group in the VPC that has the following inbound rule (In this case, I intend to create a RDS instance with MySQL as the engine):
I created an RDS instance with MySQL as the engine, made sure it had public accessibility, and made sure the security group of the VPC was the one I created.
I then tried connecting to the database via both MySQL Workbench and pgAdmin, but both ran into the same issue. I tried using my IP as the source for the security group inbound rule – that didn't work. I then set the source to 0.0.0.0/0, which I understand is all sources; that also unfortunately didn't work.
Any ideas what else I could be doing wrong here? Thanks.
Well, seems I managed to figure it out, albeit indirectly.
I gave up working with AWS and decided to try MongoDB. When connecting to MongoDB Atlas, once again, I couldn't connect. I read up the troubleshooting page in the docs and saw that they recommend you use an outgoing port tester to check if you can reach them from the port they use (27017 in their case). I tested it and found that it wasn't working. I checked to see if it had to do with my firewall (I'm on mac); I disabled it but it didn't do anything. I disabled my VPN (ProtonVPN) and it turned out that it was what was causing the issue. But that's not all there is to it. Although the outgoing port test was working, I still couldn't successfully connect to the DB. So I went to configure the inbound IP address rules so that it would accept from any source, and that was the final fix needed.
I'm not used to AWS and how some services actually work but in this exact moment I need to add some users to a MySQL database (RDS service) and allow some IPs to access it, and if someone can help me I really appreciate.
I did some research and found that I can connect to the EC2 instance and access the CLI and that would be enough, but I can't find any running instance in any region.
Thanks for your time.
Connect to your RDS instance as the root user, and add an account just like you would with a MySQL database running anywhere else. There is no special AWS procedure here.
If the database has the "publicly accessible" flag enabled, then you just need to add the IP address to the inbound rules in the Security Group assigned to the RDS instance. If the database is not "publicly accessible" then you won't be able to give access to external IP addresses.
I am trying to setup RDS on my AWS account. I created the RDS instance, But I am not able to access the database interface. I am trying to access it using putty, But it is saying - "Command not found".
Please clarify whether I am missing something.
Thanks
You didn't mention the RDS Database engine you are using, but here are some general tips.
Use a local database client (such as mysql workbench for mysql)
Make sure your RDS security group allows your local ip address to access the RDS instance on the correct port.
If you give more information about your setup we'll be able to help you more.
i have 3 servers for three applications on aws ec2 using MySql database,
now each of the application is having amember that is client subscription app,
it connects with sql databse that is created in each instance
so in this way every amamber app is having diffrent database in each server,
now we are working with a device ROKU we need to pass the XML attributes from amember to it
to varify the user so he can watch online streaming tv.
the objective
now i need to make one database that will be connected with each server using amember
so each server access one database .
Options
my options are aws RDS ,dynamoDb
Now can anyone put me in the right direction, for that.
in simple Words
need to connect my multiple apps (same app) with one database
HELLLLP
If you need to connect to a mysql database, DynamoDB is not the answer. It isn't a mysql database.
RDS is a mysql database. It connects like any other mysql database. You haven't mentioned what language[s] you are using, however. Googling "connect to mysql with [language]" should help.
I think it would be best to stick with relational databases such as MySQL.
Amazon RDS is a managed MySQL solution, but you don't have to use it for your needs.
You can use one of your EC2 instances or a new EC2 instance as the central DB and connect all the other servers to it for quires. There are pros and cons for choosing RDS over your own SQL server. If you have any questions there, feel free to edit your question and add them.
EDIT according to comment
In order to connect your application with the local MySQL. Your are probably using a connection string that points to either "localhost" or "127.0.0.1"... That is the IP of your local machine. You will have to change it to the remote IP of the machine where the DB is stored remotely.
Amazon officially states: "Amazon RDS gives you access to the full capabilities of a familiar MySQL database. This means the code, applications, and tools you already use today with your existing MySQL databases work seamlessly with Amazon RDS."
I don't get this. Amazon RDS is accessible via web services and there a client libraries (like the one for .Net).
So if I have an existing .Net application that uses a DAL which in turn queries MySQL, how can I make the same DAL talk to the Amazon RDS (via the web services). Or am I missing something here?
Amazon RDS is pure MySQL, accessible by your app the same way as any other MySQL database; the web services interface to RDS is purely for creation, deletion, and modification of the DB instances, not the DB data. From their FAQ:
Q: How do I access my running DB
Instance?
Once your DB Instance is available,
you can retrieve its
endpoint via the DescribeDBInstance
API. Using this endpoint you can
construct the connection string
required to connect directly with your
DB Instance using your favorite
database tool or programming language.
In order to allow network requests to
your running DB Instance, you will
need to authorize access. For a
detailed explanation of how to
construct your connection string and
get started, please refer to our
Getting Started Guide.
This is the part of the Getting Started Guide you need -- it explains how to get the hostname of your new instance so you can connect to it, authorize the instance for access from the client, and then connect using the MySQL command-line client (as an example):
$ rds-describe-db-instances --headers
$ rds-authorize-db-security-group-ingress default --cidr-ip 192.0.2.0/30 --headers
$ mysql -h myinstance.crwjauxgijdf.us-east-1.rds.amazonaws.com -P 3306 -u mymasteruser -p
Amazon RDS is just a normal server with normal MySQL access. There's only the webservice that handles instance creation etc., but everything mysql related is still the same.
