hhvm – maszyna wirtualna z kompilatorem JIT dla PHP

HHVM-Logo
Co to jest HHVM ?

HHVM maszyna wirtualna jest open-source, przeznaczony do wykonywania programów napisanych w Hack i PHP.
HHVM używa (JIT) podejście kompilacji Just-in-time, aby osiągnąć wysoką wydajność przy zachowaniu elastyczności rozwoju, jakie zapewnia PHP.

Instalacje jaką dziś wam pokaże przeprowadzam na systemie Debian 8 z serwerem WWW nginx/1.9.4

Pamiętaj że aby wszystko zadziałało wymagane jest posiadanie poprawnie skonfigurowanego serwera WWW z PHP !!

apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0x5a16e7281be7a449
deb http://dl.hhvm.com/debian jessie main | tee /etc/apt/sources.list.d/hhvm.list
apt-get update
apt-get install hhvm

Jeśli serwer zwraca błędy typu “segmentation fault” zaintsaluj:

apt-get install hhvm-dbg

Wersja Deweloperska

apt-get install hhvm-nightly
apt-get install hhvm-nightly-dbg

Po instalacji uruchamiamy skrypt:

/usr/share/hhvm/install_fastcgi.sh

Pobieramy przygotowane przeze mnie pliki konfiguracyjne:

rm /etc/hhvm/*; wget http://pliki.linuxiarz.pl/08-2015/server.ini -O /etc/hhvm/server.ini; wget http://pliki.linuxiarz.pl/08-2015/php.ini -O /etc/hhvm/php.ini

Edytujemy plik VierualHosta w nginx modyfikując lekko lokalizacje socketu z PHP-FPM

location ~ \.php$ {
                try_files $uri =404;
				fastcgi_pass unix:/var/run/hhvm/hhvm.sock;
				unix:/var/run/php5-fpm.sock backup;
				fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;

        }

Włączamy uruchamianie hhvm przy starcie:

update-rc.d hhvm defaults

i uruchamiany hhvm oraz restartujemy nginx:

/etc/init.d/hhvm start
/etc/init.d/nginx restart
