Note: with Apache 2.4.6, you will see the warning message below if
you use apachectl -t -D DUMP_MODULES:
Passing arguments to httpd using apachectl is no longer supported. You can only start/stop/restart httpd using this script. If you want to pass extra arguments to httpd, edit the /etc/sysconfig/httpd config file.
But you will see the list of modules displayed. You can determine the
version of Apache that is running with httpd -v.
# httpd -v Server version: Apache/2.4.6 (CentOS) Server built: Nov 19 2015 21:43:13
If you have PHP on the system and are using Apache 2.x and a version of PHP greater than or equal to 4.3.2 or a version of PHP greater than or equal to 5.0 with Apache 1 or 2, you can see a list of the loaded modules using the following PHP code:
<?php print_r(Apache_get_modules()); ?>
That will result in a display similar to the following:
To print each module on a separate line, you can use the following code:
<?php
$mod_array = apache_get_modules();
foreach($mod_array as $val) {
print "$val
\n";
}
?>That would produce a list similar to the following one:
core mod_so http_core mod_access_compat mod_actions mod_alias mod_allowmethods mod_auth_basic mod_auth_digest mod_authn_anon mod_authn_core mod_authn_dbd mod_authn_dbm mod_authn_file mod_authn_socache mod_authz_core mod_authz_dbd mod_authz_dbm mod_authz_groupfile mod_authz_host mod_authz_owner mod_authz_user mod_autoindex mod_cache mod_cache_disk mod_data mod_dbd mod_deflate mod_dir mod_dumpio mod_echo mod_env mod_expires mod_ext_filter mod_filter mod_headers mod_include mod_info mod_log_config mod_logio mod_mime_magic mod_mime mod_negotiation mod_remoteip mod_reqtimeout mod_rewrite mod_setenvif mod_slotmem_plain mod_slotmem_shm mod_socache_dbm mod_socache_memcache mod_socache_shmcb mod_status mod_substitute mod_suexec mod_unique_id mod_unixd mod_userdir mod_version mod_vhost_alias mod_dav mod_dav_fs mod_dav_lock mod_lua prefork mod_proxy mod_lbmethod_bybusyness mod_lbmethod_byrequests mod_lbmethod_bytraffic mod_lbmethod_heartbeat mod_proxy_ajp mod_proxy_balancer mod_proxy_connect mod_proxy_express mod_proxy_fcgi mod_proxy_fdpass mod_proxy_ftp mod_proxy_http mod_proxy_scgi mod_systemd mod_cgi mod_php5
