I've been working on my new server configuration for my website and now I'm a little stuck...
How I can access my RDS instance (MySQL) without using the very long AWS DNS address?
Like I would be able to access my RDS instance from: db.exemple.com using a A, CNAME or any other DNS record.
Here's the new configuration:
Amazon EC2 - Linux Instance - Ubuntu 12.04 w/ LAMP
for web services like PHP, Apache, Zend, etc.
Amazon RDS - MySQL Instance
for MySQL database
separated from EC2 instance for performance and managing purpose
You could create a CNAME record that would map to the RDS address. However, it would be rather pointless. All you will get is an extra DNS lookup.

I have an ec2 box, it is an ubuntu 18.04 OS. I can using "ssh -i {pemfile} ubuntu#{ip address}" also "ssh -i {pemfile} ubuntu#{ip-ipaddress.us-east-2.compute.internal}" from another EC2 box. Now I wanted to change the hostname and use it in ssh. I followed some of linux and AWS articles AWS Article and changed /etc/hostname and /etc/hosts file. Can not use route 53 DNS entry as per requirement.
/etc/hosts = 10.0.1.190 dev-host.example.trade
/etc/hostname = dev-host.example.trade
Getting below error "ssh -i {pemfile} ubuntu#dev-host.example.trade"
ssh: Could not resolve hostname dev-host.example.trade: Name or service not known.
As you’ve made the changes on the server only these will only be resolvable on that host (otherwise anyone could use any domain).
There are a few options you can take if you want to use a custom domain name.
The obvious one is you can use a domain you control, this will allow it to resolve across any hosts that are able to resolve your public DNS. If you don’t own a domain you can purchase one through a registrar (such as Route 53).
The second option is to look at using Route 53 private hosted zones. By attaching to your VPC you can set DNS records that resolve within your VPC. If you want these records to resolve in a hybrid network you would need to look at adding a DNS resolver.
The third option is to look at using a resource that can resolve the domain name, to do this you would either join a domain (using a service such as managed active directory or simple directory), or you could setup an EC2 host to resolve DNS. This is an expensive solution and the most complex if you’re using a hybrid architecture.
Take a look at the Centralized DNS management of hybrid cloud with Amazon Route 53 and AWS Transit Gateway post for more information about hybrid DNS
Your local machine knows nothing about changes you've made to the EC2 configuration. Those changes are local to the EC2 instance.
One way to connect to your cloud instance via a DNS name like dev-host.example.trade is to associate an elastic IP to the EC2 instance. Elastic IPs persist even if the instance is rebooted.
Next, create a new A-type DNS record at your DNS provider pointing to the newly issued IP address.
You can now connect to the server with the DNS name.
I have created a MySQL RDS instance on AWS under free-tier. I can access the Database with endpoint and username password on MySQL workbench software to upload my schema and even on localhost I can fetch data from DB on my local page running on xampp.
But when I try to fetch it from another machine it couldn't be accessed.
I tried lost of other systems.
As I'm new to AWS I wanted to know that if free-tier RDS instance will be only accessing from my system or AM I missing something like any settings like inbound and outbound rules?
Let me tell you guys I want to use it for collage project.
Head over to your rds instance and take note of the security group ID. In the ec2 menu you can set inbound and outbound rules for that security group.
We have a Phoenix App that is connecting to an AWS Aurora RDS instance for the database. However, we are using the DNS string (e.g. company.cluster-sdfssfd.us-east-1.rds.amazonaws.com) which is dynamic. Last night we noticed that the underlying ips were rotated by AWS, however, our app did not pick up on these changes and was trying to write to the old dns mapped host which was now a read-only replica. How can we get Phoenix/Ecto to automatically refresh the DNS?
I recently got an Amazon EC2 micro server to learn how to use nodejs. (I am not servers savvy BTW).
I managed to install everything and having nodejs running on the server and running their example script.
on Amazon I set the server security group to allow all / icmap - all/ tcp - 0-65535/ ssh/HTTP/HTTPS so basically everything is allowed more or less.
My question is how can I find my nameserver so I can use them on a new domain that I've bought.
I might be completely wrong and missing many steps if so. Do you know of a good tutorial on how to do that?
Thanks and sorry for the general question.
I believe what you want to do is point your domain to your new server.
You can do a couple of things in your domain registrar (where you bought your domain)
Add an A PTR record on your domain to point to the IP address of the server.
Add a CNAME record to point to the EC2 DNS name of your instance.
You can find the IP address and EC2 DNS name of your instance on the EC2 console:
You need to setup your domain name on Amazon's Route 53 DNS service in order to use their nameservers. Check out the link on how to retrieve the nameservers: http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/GetInfoAboutHostedZone.html
learning amazon aws these days,i've encountered a problem.To test NerdDinner app in amazon ec2,i have set up an ec2 instance with a security group that accepts connections to SQL Server port 1433,and i have created an rds instance and i added all IPs +EC 2 security group(port 1433)
using vs 2010 aws toolkit, when i try to create a database,the rds instance is still asking for my IP to be added to the db security group.See the pics.
The strange thing is that when i connect from another wifi(home wifi),i can access to the db instance.Now i can't access it from company wifi.
Is port 1433 open at your office? You might want to verify that.
