I'm using openshift to evaluate/mess about with jboss's BRMS tool through their workshop they have start up on the page:

http://www.jboss.org/products/brms/get-started/#!project=brms

I have loaded it onto an openshift account I created a ruby application as per instructions. When I click on the link from the openshift I get the dreaded 404 message.

I'm able to see the following when I look into the ruby.log on openshift.

[Sat May 16 05:08:49 2015] [notice] Apache/2.2.15 (Unix)  Phusion_Passenger/3.0.2

10.35.151.240 - - [16/May/2015:05:10:10 -0400] "HEAD / HTTP/1.1" 404 - "-" "Ruby"

I can see the line

(98)Address already in use: make_sock: could not bind to address 127.8.64.129:80 80 no listening sockets available, shutting down

Is there something that I should have done (or can do) to avoid this? I haven't made any changes to the product (I haven't been able to access it). I have tried stopping and re-started as well as deleting and re-installing.

Thanks,

PS. I'm a non-techie so if a solution strikes you as too simple please let me know, I probably won't have thought of it.

The error message "Address already in use", where the address includes a port number (:80), means what it says: Another process is already listening on port 80. Apparently you have a web server already running on that host, already listening on port 80, so openshift can't listen there too.

To find which process is already listening, run 

sudo netstat -napW -A inet | grep ':80.*LISTEN'

Then stop the service it corresponds to.
