how can i find out which modules are loaded in apache?

Question

Is there a command in Linux to find out which modules are loaded and running in Apache?

Answer 1

You can use apachectl (or apache2ctl)

apachectl  -D DUMP_MODULES

Answer 2

httpd -M

or if you're using Ubuntu try

apache2 -M or apache2ctl -M

Answer 3

httpd -l         # for static modules
httpd -M         # for shared modules

Or on Ubuntu:

apache2 -l         # for static modules
apache2 -M         # for shared modules

Answer 4

Another way is to use lsof.

lsof -p <apache pid> | grep mod_

This will give you a list of all loaded modules. This not only comes handy for apache, but all other processes to.
