Docker 安装 PHP
安装 PHP 镜像
方法一、通过 Dockerfile 构建
创建Dockerfile
首先，创建目录php-fpm,用于存放后面的相关东西。
w3cschool@w3cschool:~$ mkdir -p ~/php-fpm/logs ~/php-fpm/conf
logs目录将映射为php-fpm容器的日志目录
conf目录里的配置文件将映射为php-fpm容器的配置文件
进入创建的php-fpm目录，创建Dockerfile
FROM debian:jessie # persistent / runtime deps ENV PHPIZE_DEPS autoconf file g++ gcc libc-dev make pkg-config re2c RUN apt-get update && apt-get install -y $PHPIZE_DEPS ca-certificates curl libedit2 libsqlite3-0 libxml2 --no-install-recommends && rm -r /var/lib/apt/lists/* ENV PHP_INI_DIR /usr/local/etc/php RUN mkdir -p $PHP_INI_DIR/conf.d ##<autogenerated>## ENV PHP_EXTRA_CONFIGURE_ARGS --enable-fpm --with-fpm-user=www-data --with-fpm-group=www-data ##</autogenerated>## ENV GPG_KEYS 0BD78B5F97500D450838F95DFE857D9A90D90EC1 6E4F6AB321FDC07F2C332E3AC2BF0BC433CFC8B3 ENV PHP_VERSION 5.6.22 ENV PHP_FILENAME php-5.6.22.tar.xz ENV PHP_SHA256 c96980d7de1d66c821a4ee5809df0076f925b2fe0b8c362d234d92f2f0a178e2 RUN set -xe && buildDeps=" $PHP_EXTRA_BUILD_DEPS libcurl4-openssl-dev libedit-dev libsqlite3-dev libssl-dev libxml2-dev xz-utils " && apt-get update && apt-get install -y $buildDeps --no-install-recommends && rm -rf /var/lib/apt/lists/* && curl -fSL "http://php.net/get/$PHP_FILENAME/from/this/mirror" -o "$PHP_FILENAME" && echo "$PHP_SHA256 *$PHP_FILENAME" | sha256sum -c - && curl -fSL "http://php.net/get/$PHP_FILENAME.asc/from/this/mirror" -o "$PHP_FILENAME.asc" && export GNUPGHOME="$(mktemp -d)" && for key in $GPG_KEYS; do gpg --keyserver ha.pool.sks-keyservers.net --recv-keys "$key"; done && gpg --batch --verify "$PHP_FILENAME.asc" "$PHP_FILENAME" && rm -r "$GNUPGHOME" "$PHP_FILENAME.asc" && mkdir -p /usr/src/php && tar -xf "$PHP_FILENAME" -C /usr/src/php --strip-components=1 && rm "$PHP_FILENAME" && cd /usr/src/php && ./configure --with-config-file-path="$PHP_INI_DIR" --with-config-file-scan-dir="$PHP_INI_DIR/conf.d" $PHP_EXTRA_CONFIGURE_ARGS --disable-cgi # --enable-mysqlnd is included here because it's harder to compile after the fact than extensions are (since it's a plugin for several extensions, not an extension in itself) --enable-mysqlnd # --enable-mbstring is included here because otherwise there's no way to get pecl to use it properly (see https://github.com/docker-library/php/issues/195) --enable-mbstring --with-curl --with-libedit --with-openssl --with-zlib && make -j"$(nproc)" && make install && { find /usr/local/bin /usr/local/sbin -type f -executable -exec strip --strip-all '{}' + || true; } && make clean && apt-get purge -y --auto-remove -o APT::AutoRemove::RecommendsImportant=false -o APT::AutoRemove::SuggestsImportant=false $buildDeps COPY docker-php-ext-* /usr/local/bin/ ##<autogenerated>## WORKDIR /var/www/html RUN set -ex && cd /usr/local/etc && if [ -d php-fpm.d ]; then # for some reason, upstream's php-fpm.conf.default has "include=NONE/etc/php-fpm.d/*.conf" sed 's!=NONE/!=!g' php-fpm.conf.default | tee php-fpm.conf > /dev/null; cp php-fpm.d/www.conf.default php-fpm.d/www.conf; else # PHP 5.x don't use "include=" by default, so we'll create our own simple config that mimics PHP 7+ for consistency mkdir php-fpm.d; cp php-fpm.conf.default php-fpm.d/www.conf; { echo '[global]'; echo 'include=etc/php-fpm.d/*.conf'; } | tee php-fpm.conf; fi && { echo '[global]'; echo 'error_log = /proc/self/fd/2'; echo; echo '[www]'; echo '; if we send this to /proc/self/fd/1, it never appears'; echo 'access.log = /proc/self/fd/2'; echo; echo 'clear_env = no'; echo; echo '; Ensure worker stdout and stderr are sent to the main error log.'; echo 'catch_workers_output = yes'; } | tee php-fpm.d/docker.conf && { echo '[global]'; echo 'daemonize = no'; echo; echo '[www]'; echo 'listen = [::]:9000'; } | tee php-fpm.d/zz-docker.conf EXPOSE 9000 CMD ["php-fpm"]
通过Dockerfile创建一个镜像，替换成你自己的名字
w3cschool@w3cschool:~/php-fpm$ docker build -t php:5.6-fpm .
创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像
w3cschool@w3cschool:~/php-fpm$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE php 5.6-fpm 025041cd3aa5 6 days ago 456.3 MB
方法二、docker pull php
查找Docker Hub上的php镜像

这里我们拉取官方的镜像,标签为5.6-fpm
w3cschool@w3cschool:~/php-fpm$ docker pull php:5.6-fpm
等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为php,标签为5.6-fpm的镜像。
使用php-fpm镜像
运行容器
w3cschool@w3cschool:~/php-fpm$ docker run -p 9000:9000 --name myphp-fpm -v ~/nginx/www:/www -v $PWD/conf:/usr/local/etc/php -v $PWD/logs:/phplogs -d php:5.6-fpm 00c5aa4c2f93ec3486936f45b5f2b450187a9d09acb18f5ac9aa7a5f405dbedf w3cschool@w3cschool:~/php-fpm$
命令说明:
-p 9000:9000 :将容器的9000端口映射到主机的9000端口
--name myphp-fpm :将容器命名为myphp-fpm
-v ~/nginx/www:/www :将主机中项目的目录www挂载到容器的/www
-v $PWD/conf:/usr/local/etc/php ：将主机中当前目录下的conf目录挂载到容器的/usr/local/etc/php
-v $PWD/logs:/phplogs ：将主机中当前目录下的logs目录挂载到容器的/phplogs
查看容器启动情况
w3cschool@w3cschool:~/php-fpm$ docker ps CONTAINER ID IMAGE COMMAND ... PORTS NAMES 00c5aa4c2f93 php:5.6-fpm "php-fpm" ... 0.0.0.0:9000->9000/tcp myphp-fpm
通过浏览器访问phpinfo()
PS:此处是通过nginx+php实现web服务，nginx配置文件的fastcgi_pass应该配置为myphp-fpm容器的IP。
fastcgi_pass 172.17.0.4:9000;
容器IP的查方法
docker inspect 容器ID或容器名 |grep '"IPAddress"'
