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。

  1. w3xue@w3xue:~$ 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

  1. FROM debian:jessie
  2.  
  3. # persistent / runtime deps
  4. ENV PHPIZE_DEPS 		autoconf 		file 		g++ 		gcc 		libc-dev 		make 		pkg-config 		re2c
  5. 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/*
  6.

  21. 		--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)
  22. 		--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

  29. 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"
  30. 		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
  31. 		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
  32.  
  33. EXPOSE 9000
  34. CMD ["php-fpm"]

通过Dockerfile创建一个镜像，替换成你自己的名字

  1. w3xue@w3xue:~/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

  1. w3xue@w3xue:~/php-fpm$ docker images
  2. REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
  3. 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

  1. w3xue@w3xue:~/php-fpm$ docker search php
  2. NAME                      DESCRIPTION                                     STARS   OFFICIAL  AUTOMATED

  14. ...

这里我们拉取官方的镜像,标签为5.6-fpm

  1. w3xue@w3xue:~/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

  1. w3xue@w3xue:~/php-fpm$ docker run -p 9000:9000 --name  myphp-fpm -v ~/nginx/www:/www -v $PWD/conf:/usr/local/etc/php -v $PWD/logs:/phplogs   -d php:5.6-fpm
  2. 00c5aa4c2f93ec3486936f45b5f2b450187a9d09acb18f5ac9aa7a5f405dbedf
  3. w3xue@w3xue:~/php-fpm$

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

  1. w3xue@w3xue:~/php-fpm$ docker ps
  2. CONTAINER ID    IMAGE         COMMAND      ...    PORTS                    NAMES
  3. 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。

  1. fastcgi_pass  172.17.0.4:9000;

容器IP的查方法

  1. docker inspect 容器ID或容器名 |grep '"IPAddress"'
