Docker 入门教程 Docker 安装 PHP
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

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
w3cschool@w3cschool:~/php-fpm$ docker search php

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"'
