Apache Modules

How to find out which modules are available and installed.

Apache may come with a variety of modules. To find out whats installed on your host, run the following:

bash-2.05a$ pwd
/usr/local/apache/bin
bash-2.05a$ ./httpd -l
Compiled-in modules:
  http_core.c
  mod_env.c
  mod_log_config.c
  mod_mime.c
  mod_negotiation.c
  mod_status.c
  mod_include.c
  mod_autoindex.c
  mod_dir.c
  mod_cgi.c
  mod_asis.c
  mod_imap.c
  mod_actions.c
  mod_userdir.c

suexec: disabled; invalid wrapper /usr/local/apache/bin/suexec

There is a warning that suexec is disabled, but usually it is not important.

If you don't have access to the box, you may try upload a php script with the following contents:

<?
  phpinfo();
?>

If you do a find for Loaded Modules on the output of that page you should see the list of apache modules.
