使用docker-compose快速搭建PHP开发环境

一、前期准备

需要准备php，mysql，nginx镜像。下面是我安装的镜像。

[root@localhost ~]# docker images
REPOSITORY                        TAG                 IMAGE ID            CREATED             SIZE
docker.io/phpdockerio/php72-fpm   latest              01cc79d26d94        9 days ago          164 MB
docker.io/mysql                   latest              e3fcc9e1cc04        13 days ago         544 MB
docker.io/nginx                   latest              8cf1bfb43ff5        13 days ago         132 MB

目录结构如下：

[root@localhost ~]# tree /www
/www
├── conf
│   └── php.conf
├── logs
└── web
    └── index.php

3 directories, 2 files

web 是网站的目录
conf Nginx的配置目录

其中，/www/conf/php.conf下的文件内容如下：

server {
    listen  80;
    server_name localhost;

    location / {
        root    /usr/share/nginx/html;
        index   index.html index.htm index.php;
    }

    error_page  500 502 503 504 /50x.html;
    location = /50x.html {
        root    /usr/share/nginx/html;
    }

    location ~ \.php$ {
        fastcgi_pass    php:9000;
        fastcgi_index   index.php;
        fastcgi_param   SCRIPT_FILENAME /web/$fastcgi_script_name;
        include     fastcgi_params;
    }
}

二、编写docker-compose.yml文件

在工作的目录下创建docker-compose.yml文件。

version: "2.3"
services:
  nginx:
    image: nginx
    privileged: true
    ports: 
      - "80:80"
    volumes: 
      - /www/web:/usr/share/nginx/html
      - /www/conf:/etc/nginx/conf.d
      - /www/logs:/var/log/nginx
    networks:
      - web-net
  php:
    image: phpdockerio/php72-fpm
    privileged: true
    volumes:
      - /www/web:/web
    networks:
      - web-net
  mysql:
    image: mysql
    ports:
      - "3306:3306"
    environment:
      - MYSQL_ROOT_PASSWORD=root
    networks:
      - web-net
networks: 
  web-net:

严格注意yaml格式。

privileged 用来设置容器，需要操作挂载的权限

实例：

[root@localhost ~]# docker-compose up -d
Creating network "root_web-net" with the default driver
Creating root_nginx_1 ... done
Creating root_php_1   ... done
Creating root_mysql_1 ... done

构建成功
在/www/web下，新建index.php，能正常访问。
