Installing New Comodo Positive SSL Certificate on Apache and OpenSSL on Centos, Fedora and RedHat


I had to buy a certificate and install it on my new server

I was issued with a new certificate by Comodo under Comodo Positive SSL. To start with I think it doesn’t matter which certificate you choose, end of the day they all follow pretty much same standards and the only thing that make a certificate expensive is a company or issuing authority such as thwate (expensive).

I personally always choose a cheapest certificate on market.

Anyway with latest certificate I received 4 files in an archive as shown below


You could just install a certificate by adding

and it will work on some browsers but you would need intermediate cert as well. Here is what always gets me. With latest PositiveSSL They give us 3 files which we need to combine and feed it to

So to do that you will run this command

Considering that all you files are under /home/crt/2014 folder our final VirtualHost confg will look like this


Once you made above change, don’t forget to restart your apache service generally located as /etc/init.d/httpd restart on Centos and Red Hat OS

If you have any comment or would like to point out any error please leave your comments.
