Ukulungiswa kokusebenza kwe-Apache2

Abantu abaningi basebenzisa i-apache2 njengeseva yewebhu. Kodwa-ke, bambalwa abantu abacabanga ngokuthuthukisa ukusebenza kwayo, okuthinta ngokuqondile isivinini sokulayisha samakhasi esayithi, isivinini sokucubungula izikripthi (ikakhulukazi i-php), kanye nokwanda komthwalo we-CPU nokwanda kwenani le-RAM esetshenzisiwe.

Ngakho, imanuwali elandelayo kufanele isize abaqalayo (hhayi kuphela) abasebenzisi.
Zonke izibonelo ezingezansi zisetshenziswe ku-Raspberry PI 3, Debian 9, Apache 2.4.38, PHP 7.3.

Ngakho, ake siqale.

1. Ikhubaza amamojula angasetshenzisiwe

Indlela yokuqala ukumane ukhubaze amamojula ongawasebenzisi:

Uhlu lwamamojula asetshenziswa njengamanje lungabonwa ngomyalo:

apache2ctl -M

Ukuze ukhubaze imojuli, sebenzisa umyalo:

a2dismod *название модуля*

Ngakho-ke, ukuze uvule imojuli, sebenzisa umyalo:

a2enmod *название модуля*

Sicela uqaphele ukuthi uma usebenzisa a2dismod, igama lemojuli kufanele libhalwe ngaphandle kwemojuli yegama ngokwayo.

Isibonelo, uma usekukhiqizweni komyalo apache2ctl -M wabona imojula_ummeleli, bese ukuyikhubaza udinga ukusebenzisa umyalo - ummeleli we-a2dismod

Amamojula alayisha isistimu kakhulu (kusukela kokuhlangenwe nakho komuntu siqu) yilawa:

• I-PHP, i-Ruby, i-Perl namanye amamojula ezilimi ezihlukahlukene zokubhala
• I-SSL
• Phinda ubhale
• CGI

Ngakho-ke ezimeni lapho ungawadingi la mamojula, ngincoma ukuthi ukhubaze lawa mamojula.

Futhi, ngemuva kokukhubaza noma iyiphi imojula, ngincoma ukusebenzisa umyalo - i-apache2ctl configtest, okuzohlola ukucushwa kwamasayithi asetshenzisiwe futhi uma noma yimaphi amamojula akhubazekile abedingeka kuwo, azodala iphutha.

2. Ukushintsha i-MPM (I-Multi-Processing Module) nokusebenzisa i-php-fpm

Ngokuzenzakalelayo, ngemva kokufakwa, i-apache2 isebenzisa i-MPM Prefork (intambo engu-1 ngokuxhumeka kwe-1), okunciphisa kakhulu ukusebenza, kodwa ngesikhathi esifanayo kuthuthukisa ukuzinza nokuphepha.

Kepha ukukhulisa ukusebenza kahle, ngincoma ukusebenzisa i-MPM Worker, ekuvumela ukuthi usebenzise imicu eminingi ekuxhumekeni ngakunye.

Ukuyivumela sisebenzisa imiyalo elandelayo:

a2dismod mpm_prefork  //Отключаем prefork
a2dismod php7.3  //Отключаем модуль php, который зависит от prefork
a2enmod mpm_worker  //Включаем worker

Kodwa-ke, uma usebenzisa i-Worker ungase uhlangabezane nenkinga ngoba... Imojula ye-php7.3 incike kumojula ye-Prefork.

Ukuxazulula le nkinga, asifake imojula ye-php7.3-fpm, ezosetshenziswa ukuqhuba imibhalo ye-PHP:

apt-get update && apt-get install php7.3-fpm  //Устанавливаем
systemctl enable php7.3-fpm && systemctl start php7.3-fpm  //Добавляем в автозагрузку и запускаем
a2enmod php7.3-fpm && a2enconf php7.3-fpm.conf  //Включаем модуль и конфиг для него

Kuyaqapheleka ukuthi ukusebenzisa i-php-fpm kuzophinde kunciphise inani le-RAM esetshenziswa inqubo ye-apache2 futhi kusheshise kancane ukucutshungulwa kwemibhalo ye-PHP.

3. Isiphetho

Ngakho-ke, ngezenzo ezilula ezinjalo sakwazi ukukhulisa ukusebenza nokunciphisa umthwalo emshinini (kulokhu i-RPI3).

Yiqiniso, kunamakhulu ezinye izinketho zokuthuthukisa, njengokuvumela ukucindezelwa (okuwusizo ngempela, kodwa iningi selivele linikwe amandla ngokuzenzakalelayo), ukushintsha izilungiselelo ze-MPM (amafayela okusetha), ukukhubaza i-HostnameLookups, njll., kodwa kulesi sihloko ngizamile bonisa Lawa amaphuzu angisize kakhulu, futhi ngethemba ukuthi azosiza abanye.
