Route a specific path to a specific EC2 instance using Route 53

Question

I'm not sure if this is even possible, but if so I'm looking for the best way to do it.

Say I want to host my blog for example.com on it's own EC2 instance, and I want the path to my blog to be example.com/blog

Is it possible to route all requests to example.com/blog/* to one instance, and all other requests to that domain elsewhere?

My web server is Apache.

Thanks!

Answer 1

You can now do this with Application Load Balancer and path-based routing: https://docs.aws.amazon.com/elasticloadbalancing/latest/application/tutorial-application-load-balancer-cli.html#path-based-routing-aws-cli

Answer 2

Certainly it's possible, but not with DNS nor with an ELB. The most common solution to this is to use a web server that issues a 301 or 302 redirect.

In your case, example.com would point to whatever the main site is. The web server (nginx or Apache httpd, perhaps) hosting example.com would have a redirect for example.com/blog/* that is found at another destination.

Here's an SO post on using Nginx for a redirect and for using Apache for a redirect.

Answer 3

Yes, but you would have to proxy your requests through an instance handling example.com. How you configure this depends on your web server.

Some examples on how to configure this:

• nginx: http://wiki.nginx.org/HttpProxyModule
• Apache: http://httpd.apache.org/docs/2.2/mod/mod_proxy.html
