I am running several EC2 instances behind ELB load balancers. Can I insert my SSL certificate into Apache server without insert my cert into the load balancers?

How should I set for the load balancers? Change the rules of security groups or something else?

Yes. That's possible.

To do the same, at the Load Balancer level, use TCP as the Load Balancer Protocol instead of HTTPS. Use the port 443 as Load Balancer port as well as the Instance Port.

If you use the HTTPS then you have to provide with the SSL details, but simply passing it through with TCP will work perfectly.

I am doing the same in my setup.

Extracted from the ELB docs here...

Elastic Load Balancing supports SSL termination at the Load Balancer, including offloading SSL decryption from application instances, centralized management of SSL certificates, and encryption to back-end instances with optional public key authentication.

So the best option will be to place your SSL certs there, as long as you want to set that certificate to all your cluster.
