Why this ?

I'd like to know which Apache modules are really used to remove the other ones from the config files and having a smaller apache process memory footprint.

Requirements

• apache server-info module enabled
• curl
• python3

How is it working ?

This script is analyzing the server-info page, showing you how and where your modules are configured or used

If the module is configured but not used it will suggest to remove it.

How to use it ?

Dump the content of Apache server-info page to a file. The server-info page should be dumped only after the site has been used. This imply that all the modules needed are used.

curl http://localhost/server-info > http_modules_test.txt
cat http_modules_test.txt| python find_unused_apache_mod.py

1
Module name mod_python.c
Configuration Phase Participation: 4
Request Phase Participation: 11
Current Configuration: 3

2
Module name mod_version.c
Configuration Phase Participation: 0
Request Phase Participation: 0
Current Configuration: 1

3
Module name mod_proxy_connect.c
Configuration Phase Participation: 0
Request Phase Participation: 0
Current Configuration: 0

To remove safely:
 ['mod_proxy_connect.c']
POPPED:  mod_proxy_connect.c

To KEEP:  ['mod_python.c', 'mod_version.c', 'mod_proxy_connect.c']

You can test on a real case example with:

cat http_modules.txt| python find_unused_apache_mod.py
