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
