Finding Apache configuration file (httpd.conf) location Jun 08, 2011

Just a quick tip for programmers working with Apache. Sometimes I’m asked where to find the Apache configuration file on a given server. Since it’s possible to configure this there is no “default location” so I usually do:

$ ps -ef | grep apache

which gives me a list like

deploy@cmd01:/$ ps -ef | grep apache
root      4053     1  0 06:26 ?        00:00:04 /usr/sbin/apache2 -k start
www       5189  4053  0 11:00 ?        00:00:00 /usr/sbin/apache2 -k start
www       5199  4053  0 11:00 ?        00:00:00 /usr/sbin/apache2 -k start

Then simply run

$ /usr/sbin/apache2 -V

and you will get the details you need, specifically this

Server compiled with....
 -D SERVER_CONFIG_FILE="/etc/apache2/apache2.conf"

That’s it. Are you using another/faster approach? Let me know.
