这里我们使用 docker-compose

我们需要先安装一个nginx并拷贝他的配置文件

docker run -itd --name nginx -p 80:80 nginx

创建目录 

mkdir -p /opt/nginx/conf /opt/nginx/logs /opt/nginx/www

拷贝配置文件

docker cp nginx:/etc/nginx  /opt/nginx/conf

然后停止并删除nginx容器

docker stop nginx
docker rm nginx

首先我们 编写 docker-compose.yml，内容如下

version: "2.1"
services:
    nginx:
        container_name: nginx
        image: nginx
        ports:
            - "81:80"
        volumes:
            - /opt/nginx/www:/usr/share/nginx/html
            - /opt/nginx/conf:/etc/nginx
            - /opt/nginx/logs:/var/log/nginx
        networks:
            - lnmp-network
    php:
        container_name: php
        image: php:5.6-fpm-alpine3.8
        volumes:
            - /opt/nginx/www:/www
        networks:
            - lnmp-network
    mysql:
        container_name: mysql
        image: mysql
        ports:
            - "3306:3306"
        environment:
            - MYSQL_ROOT_PASSWORD=root
        networks:
            - lnmp-network
networks:
    lnmp-network:

配置 nginx

vim /opt/nginx/conf/conf.d/default.conf

    server {
        listen       80;
        server_name  localhost;
        location / {
            root  /usr/share/nginx/html;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /501x.html {
            return  200 "1221";
        }
        location ~ \.php$ {
                fastcgi_pass    php:9000;
                fastcgi_index   index.php;
                fastcgi_param   SCRIPT_FILENAME /www/$fastcgi_script_name;
                include         fastcgi_params;
        }
    }
~

运行 docker-compose.yml

docker-compose up -d

编写 index.php 文件

vim /opt/nginx/www/index.php

内容如下

<?php
  phpinfo();
?>

然后访问

http://192.168.31.147:81/index.php

就可以看到PHP经典首页了
