Docker 安装 PHP

安装 PHP 镜像

方法一、docker pull php

查找Docker Hub上的php镜像

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

这里我们拉取官方的镜像,标签为5.6-fpm

codercto@codercto:~/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。

codercto@codercto:~/php-fpm$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
php                 5.6-fpm             025041cd3aa5        6 days ago          456.3 MB

方法二、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。

codercto@codercto:~$ 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

        { \
            echo '[global]'; \

        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

codercto@codercto:~/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

codercto@codercto:~/php-fpm$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
php                 5.6-fpm             025041cd3aa5        6 days ago          456.3 MB

使用php-fpm镜像

运行容器

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

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

codercto@codercto:~/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

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"'
