I was given a server to create a test site for our services, this is the first time I been trying to do this so I did a lot of research, finally I found this page which gave great directions, but even after trying all this I can't load my simple index.php page, all I get is a timeout error page

I tried to run a debug but all I get is the following warning

httpd -X
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
(13)Permission denied: AH00058: Error retrieving pid file /run/httpd/httpd.pid
AH00059: Remove it before continuing if it is corrupted.

From all I read this is a warning. I change the permissions to the files in the /var/www folder so users can read and execute. Is there another way to run debug and find out why my sample page http://www.example.com/index.php does not load.

I am certain the problem is with my set up with the server, and I am desperate enough to post.

Here is an update on my httpd version

[@localhost html]$ httpd -v
Server version: Apache/2.4.6 (Red Hat Enterprise Linux)
Server built:   Sep 17 2015 09:06:30

[@localhost /]$ sudo systemctl status httpd.service

And this is the log file

    Exactly what are you running, and how did you install and set it up? Just linking to a tutorial doesn't tell us what you _actually_ did, nor what your environment is. – Michael Hampton Mar 09 '16 at 21:31
  • You need to run httpd with root privileges. – user9517 Mar 09 '16 at 21:32
  • `$ sudo apachectl start` and restart. http://stackoverflow.com/questions/27862664/13permission-denied-error-retrieving-pid-file-run-httpd-pid – pbu Mar 09 '16 at 21:34
  • Is there a file /run/httpd/httpd.pid? If so, it could be as simple as the Apache service already running. Stop the service and you may be able to run your debugging command. – DarkMoon Mar 09 '16 at 23:17
  • @MichaelHampton -- What do you mean when you ask what are you running? Iain -- I do run httpd with privileges using sudo. – Tavo Mar 10 '16 at 13:28

After further research I figured out that my set up was correct, it was the firewall. Thanks for all the help!. For further information please check this page
