How to check mod_headers and mod_expires modules enabled in apache

Question

I want to check whether mod_headers and mod_expires modules enabled or not in my server

Is there a way available to list apache enabled/disabled modules using some php function just like we list php information with phpinfo(); function?

Answer 1

On Debian:

user@machine:~$ /usr/sbin/apache2 -l

Most GNU/Linux distros:

user@machine:~$ /usr/sbin/httpd -l

Ubuntu:

user@machine:~$ ls /etc/apache2/mods-enabled

On Mac OSX:

user@mymac:~$ httpd -l

On Win 7 (64-bit):

C:\Users\myuser>"\Program Files (x86)\Apache Software Foundation\Apache2.2\bin\httpd.exe" -l

Try these commands from a terminal window in all but Windows, which will use CMD instead.

Answer 2

Some versions of PHP/Apache show all loaded modules in phpinfo() under "Loaded Modules".

Speeve's answer shows compiled in modules (x6 on my system):

echo system('/usr/sbin/apache2 -l');

You'll also need to see your enabled modules (x36 for me):

echo system('ls /etc/apache2/mods-enabled/');

To get the list of disabled modules, run this command then cross off all the enabled modules:

echo system('ls /etc/apache2/mods-available/');

Answer 3

On Ubuntu you can see the list of enabled modules here,

/etc/apache2/mods-enabled

Answer 4

All the above answers are wrong. Use instead:

apachectl -t -D DUMP_MODULES

or

apachectl -M
