php7 php fpm.d,基于nginx-php-fpm的docker安装php7的redis扩展memcahced扩展

镜像：https://hub.docker.com/r/richarvey/nginx-php-fpm/

php版本：FROM php:7.1.11-fpm-alpine

下载镜像并启动容器：

docker run -d richarvey/nginx-php-fpm

进入容器：

docker exec -it 08f7c84d5b84 bash

1php -m|grep redis

2mkdir -p /usr/src/php/ext/redis

3curl -L https://github.com/phpredis/phpredis/archive/3.0.0.tar.gz | tar xvz -C /usr/src/php/ext/redis --strip 1

4echo 'redis' >> /usr/src/php-available-exts

5docker-php-ext-install redis

6php -m|grep redis

手工验证没问题，将命令写入dockerfile：

RUN mkdir -p /usr/src/php/ext/redis \

&& curl -L https://github.com/phpredis/phpredis/archive/$PHPREDIS_VERSION.tar.gz | tar xvz -C /usr/src/php/ext/redis --strip 1 \

&& echo 'redis' >> /usr/src/php-available-exts \

&& docker-php-ext-install redis
