When I want to start my apache server, it shows me this error:

Starting httpd:

(98) Address already in use: make_sock: could not bind to address [::]:80

(98) Address already in use: make_sock: could not bind to address 0.0.0.0:80

no listening sockets available, shutting down Unable to open logs

[FAILED]

My httpd.conf file:

Listen 8181

As you can see, I have deleted everything else. Still, Apache wants to bind to port 80 which is used by varnish. Any idea how to solve it?

    Have you verified that the httpd.conf file you edited is [the httpd.conf file apache is using](http://serverfault.com/questions/12968/how-to-find-out-which-httpd-conf-apache-is-using-at-runtime)? – Diogenes deLight Apr 09 '17 at 21:53
  • @DiogenesdeLight Yes. Before deleting the rest of file, I got the list of all included files and checked them for any possible mis-configurations. But no luck. – undone Apr 10 '17 at 00:16
  • What I mean is something different. If you follow the link I posted, you'll see there are various ways to get apache to tell you the path to its config file. Whenever I change a config file, get no errors, and the behavior is unaffected, I like to make sure the file I edited is really the file that the program is using as its config file. I think it's worth checking that, esp. with apache. – Diogenes deLight Apr 10 '17 at 03:50

    Apache does not have a default for Listen, so it must be defined somewhere, look deeper and better. – ezra-s Apr 10 '17 at 08:52

First thing to rule out:

  • Apache is using another config file than the one you expect.

Do the following:

  1. Kill whichever httpd process you have running
  2. Start Apache in foreground with explicit conf file /sbin/httpd -f /etc/httpd/conf/httpd.conf -DFOREGROUND

Second thing:

  • Check which other config files are loaded by your httpd.conf

    grep Include /etc/httpd/conf/httpd.conf

  • Find out which of the loaded config files that have Listen directives defined.

    grep -r Listen /etc/httpd/

Some Listen directive somewhere must be hiding from you.

  • I should've deleted this question because problem was installing two instance of apache on the same server (one compiled in custom directory, the other using yum) . There was a conflict between them! – undone Apr 16 '17 at 02:23
