How to generate the certificate chain for AWS Load Balancer?

Question

Right now, for my instances I am using a Amazon ELB with SSL configured in it. But when it is active, I get an exception.

I am using Comodo / InstantSSL for my SSL needs and they give two files : The certificate .crt and the .ca-bundle 

How can I generate the certificate chain?

Answer 1

You just have to use the basic Linux commands to make this happen. I would suggest you to combine the certificate file and the bundle file. I will show you the command on how to do this. First, go to the directory where you have both the files.

cat name.crt bundlename.ca-bundle >> chainname.crt

The cat command should be in the same order, with certificate (.crt) file at the top and bundle file after that.
