gRPC für PHP installieren

Voiced by Amazon Polly

Dieser Artikel erfordert mehr Erfahrung im Umgang mit und ist daher nur für fortgeschrittene Benutzer gedacht.

gRPC

Dieses beschreibt wie man die PECL-Extension gRPC einfach in PHP integriert.

Dieses Tutorial ist als praktischer Leitfaden gedacht und behandelt keine theoretischen Hintergründe. Diese werden in einer Vielzahl von anderen Dokumenten im behandelt.

Für die Richtigkeit der Inhalte dieses Tutorials gebe ich keinerlei Garantie. Der hier gezeigte Weg ist nicht der einzige um ein solches System aufzusetzen, es ist lediglich, der, den ich bevorzuge.

Was ist gRPC?

gRPC (gRPC Remote Procedure Calls) ist ein Protokoll zum Aufruf von Funktionen in verteilten Computersystemen. Es basiert auf dem Standard HTTP/2 und Protocol Buffers.

PECL installieren

sudo apt-get install autoconf zlib1g-dev php-dev php-pear

PHP sollte bei einer aktuellen Version mit dem Flag --with-pear installiert worden sein.

Erfolg der Installation nach wenigen Minuten

Build process completed successfully
Installing '/usr/..../grpc.so'
install ok: channel://..../grpc-xx
configuration option "php_ini" is not set to php.ini location
You should add "extension=grpc.so" to php.ini

Wenn, wie erwartet, alles ohne Fehler durchgelaufen ist, fügen wir die Erweiterung unserer Konfiguration hinzu:

echo "extension=grpc.so" >> /path/to/php.ini

Restart PHP /

For php-fpm:

service -fpm restart

service apache2 restart

Only Supported Versions of PHP (http://php.net/supported-versions.php) for Supported Ubuntu Releases (https://wiki.ubuntu.com/Releases) are provided. Don't ask for end-of-life PHP versions or Ubuntu release, they won't be provided.

Debian oldstable and stable packages are provided as well: https://deb.sury.org/#debian-dpa

You can get more information about the packages at https://deb.sury.org

IMPORTANT: The -backports is now required on older Ubuntu releases.

BUGS&FEATURES: This PPA now has a issue tracker:
https://deb.sury.org/#bug-reporting

CAVEATS:

  1. If you are using php-gearman, you need to add ppa:ondrej/pkg-gearman
  2. If you are using apache2, you are advised to add ppa:ondrej/apache2
  3. If you are using nginx, you are advised to add ppa:ondrej/nginx-mainline
