ich für eine Weile gesucht fanden diese in nicht ordnungsgemäß installiert Memcached werden. Aber hier verwende ich docker Ich habe einen Memcached-Dienst erstellt.

Memcached dockerfile:

FROM memcached:1.4-alpine 

# Port to expose (default: 11211) 
EXPOSE 11211 

# Default Memcached run command arguments 
CMD ["-m", "128"] 

# Set the user to run Memcached daemon 
USER daemon 

# Set the entrypoint to memcached binary 
ENTRYPOINT memcached 

php Dockerfile

FROM php:5.6-apache 

RUN apt-get update && apt-get install -y \ 
    git \ 
    unzip

Meine Frage ist, wie der Dienst zu machen, die PHP-Skript der Lage, „zu erkennen läuft "memcached service wie memcached ist direkt auf dem host installiert und transparent für php Skriptdienst?

Answer 1

für Docker Memcached installieren (PHP-5.6) Änderung

RUN apt-get update && apt-get install -y \ 
    git \ 
    unzip 

zu

RUN apt-get update \ 
    && apt-get install -y git unzip zlib1g-dev libmemcached11 libmemcached-dev \ 
    && yes '' | pecl install memcached-2.2.0 \ 
    && docker-php-ext-enable memcached \ 
    && yes '' | pecl install memcache \ 
    && docker-php-ext-enable memcache 

und PHP-Container wieder aufzubauen, wird dies

memcache und Memcached-Erweiterungen für PHP installieren
