It is unclear what is causing the problem since this question does not provide any details apart from that "the files" are working somewhere else and that some other config is working too - which says absolutely nothing about the troubling config and thus does not help in any way.
If the server does not start and you don't why the first look should be in the servers error log. Usually you'll find the relevant information which cause the server to fail there.

If I have one server where if I do this. I tried commenting out the line mentioning that localhost. I know the question is one year old so the answer probably comes much too late but anyway, since somebody already dug this out, it may be worth putting an answer here for future visitors.
Sadly we do not have any detailed info about the distro used and what particular package provides httpd functionality Apache, Nginx, something else? The reason why the restart you mention fails is probably because you're commenting out the certificate in a general config file and leave it in some other file, probably in a vhost config. If it finds either of these strings it will print out the relevant lines prepended with the filename containing them.
You can then proceed to comment out those lines. Try to restart or test configuration after you're done. If you get through a restart successfully, then the server has stopped using the certificates.

I've been arguing with some of the simpler things in linux. I can outline all the tutorials and links that I have slowly figured out while configuring my server; but I will try to keep this to just the gritty details of my SSL adventures in the last few hours. My set up: Centos 7, apache 2. Server single purpose: Run Owncloud app. One domain only. I don't need vhosts I think, if I am wrong, kick me since this server will be a single domain forever. I've successfully generated the key file and sent the CSR to Godaddy.
Verified it, downloaded the chain file and my cert file. I noted the second link above said to comment out some lines and add some data in. Still ended up with this annoying result: When I restart httpd at the end of the process, it just whines that it can't restart the service. Why do I say idiots guide? I have to google simple things like 'how to undo changes in vi' etc. I'm clearly missing something simple. Anything that I have to type and in a certain order; or a line to edit will help me greatly.
Thanks so much in advance, beer to the one who gets me through this promise, not a bait and switch! Set the 'ServerName' directive globally's to suppress this message. Not sure if this is required or not considering my later errors. Please advise. Pass Phrase Dialog: Configure the pass phrase gathering process. The seed data should be of good random quality. So, if available, use this one instead. Use "openssl engine -v" to list supported engine names.
NOTE: If you enable an accelerator and the server does not start, consult the error logs and ensure your accelerator is functioning properly. Caveat: by giving precedence to RC4-SHA and AESSHA as in the example belowmost connections will no longer have perfect forward secrecy - if the server's key is compromised, captures of past or future traffic must be considered compromised, too.
It only takes a minute to sign up. Can you think of any linux command-line method for saving the certificate presented by a HTTPS server? The gui equivalent to what I'm looking for would be to browse to the HTTPS site, double-click on the browser "secure site" icon, and export the cert.
Except the goal here is to do it non-interactively. Note that "redundant" -servername parameter is necessary to make openssl do a request with SNI support. Sign up to join this community. The best answers are voted up and rise to the top.

When I was done setting up the server I tried to install lets-encrpty with the same domain name I used on the old server that's no longer reachable but it could not be installed.
