Otu esi elele Modul Apache akwadoro/bugoro na Linux
N'ime ntuziaka a, anyị ga-ekwu nkenke gbasara sava weebụ Apache n'ihu-njedebe yana otu esi edepụta ma ọ bụ lelee nke enyerela modul Apache na sava gị.
A na-ewu Apache, dabere na ụkpụrụ nke modularity, n'ụzọ dị otú a, ọ na-enyere ndị na-ahụ maka sava weebụ aka ịgbakwunye modul dị iche iche iji gbasaa ọrụ ya bụ isi na ịkwalite arụmọrụ apache.
Ụfọdụ n'ime modul Apache a na-ahụkarị gụnyere:
- mod_ssl – nke na-enye HTTPS maka Apache.
- mod_rewrite – nke na-enye ohere iji kwekọọ ụkpụrụ url na okwu oge niile, wee mee ntụgharị ntụgharị site na iji aghụghọ .htaccess, ma ọ bụ tinye nzaghachi koodu ọnọdụ HTTP.
- mod_security – nke na-enye gị ichekwa Apache megide mwakpo Brute Force ma ọ bụ DDoS.
- mod_status – nke na-enye gị ohere inyocha ibu sava weebụ Apache na statics ibe.
Na Linux, a na-eji iwu apachectl ma ọ bụ apache2ctl iji chịkwaa interface sava HTTP Apache, ọ bụ njedebe n'ihu Apache.
Ị nwere ike igosipụta ozi ojiji maka apache2ctl dị ka n'okpuru:
$ apache2ctl help OR $ apachectl help
Usage: /usr/sbin/httpd [-D name] [-d directory] [-f file]
[-C "directive"] [-c "directive"]
[-k start|restart|graceful|graceful-stop|stop]
[-v] [-V] [-h] [-l] [-L] [-t] [-S]
Options:
-D name : define a name for use in directives
-d directory : specify an alternate initial ServerRoot
-f file : specify an alternate ServerConfigFile
-C "directive" : process directive before reading config files
-c "directive" : process directive after reading config files
-e level : show startup errors of level (see LogLevel)
-E file : log startup errors to file
-v : show version number
-V : show compile settings
-h : list available command line options (this page)
-l : list compiled in modules
-L : list available configuration directives
-t -D DUMP_VHOSTS : show parsed settings (currently only vhost settings)
-S : a synonym for -t -D DUMP_VHOSTS
-t -D DUMP_MODULES : show all loaded modules
-M : a synonym for -t -D DUMP_MODULES
-t : run syntax check for config files
apache2ctl nwere ike ịrụ ọrụ na ụdịdị abụọ enwere ike, ọnọdụ init Sys V na ọnọdụ ngafe. Na ọnọdụ init SysV, apache2ctl na-ewe iwu dị mfe, otu okwu n'ụdị dị n'okpuru:
$ apachectl command OR $ apache2ctl command
Dịka ọmụmaatụ, ịmalite Apache wee lelee ọkwa ya, jiri ohere ọrụ mgbọrọgwụ mee iwu abụọ a site na iji iwu sudo, ọ bụrụ na ị bụ onye ọrụ nkịtị:

Ma mgbe ị na-arụ ọrụ na ọnọdụ ngafe, apache2ctl nwere ike were arụmụka Apache niile na syntax ndị a:
$ apachectl [apache-argument] $ apache2ctl [apache-argument]
Enwere ike depụta arụmụka Apache niile dị ka ndị a:
$ apache2 help [On Debian based systems] $ httpd help [On RHEL based systems]
Ya mere, ka ịlele modul ndị enyere na sava weebụ Apache gị, mee iwu dị n'okpuru maka nkesa gị, ebe -t -D DUMP_MODULES bụ Apache-argument iji gosi modul niile enyere/kwadoro. :
--------------- On Debian based systems --------------- $ apache2ctl -t -D DUMP_MODULES OR $ apache2ctl -M
--------------- On RHEL based systems --------------- $ apachectl -t -D DUMP_MODULES OR $ httpd -M $ apache2ctl -M

Ọ gwụla! N'ime nkuzi a dị mfe, anyị kọwara otu esi eji ngwa Apache n'ihu iji depụta modul apache enyere/kwadoro. Buru n'uche na ị nwere ike ịkpọtụrụ anyị site na iji akwụkwọ nzaghachi n'okpuru iji zitere anyị ajụjụ gị ma ọ bụ okwu gị gbasara ntuziaka a.
