Docker搭建PHP环境-端口篇

发表于 | 分类于 ， ， | |

本文构建起来的项目目前只支持端口访问

背景

前几天升级了下mac系统，结果php-fpm就起不来了，最后还是重装fpm才解决的。本来想着在本机上搭建php开发环境一来方便，二来不用被docker占用太多系统资源，现在看来本机环境还是存在很大缺陷：

  • 容易受本地系统更新的影响
  • 移植性不高，换一台设备就得重新安装lnmp一整套，谁知道会出来多少问题

再想想docker的好处，打包好镜像放到镜像仓库后，换了设备只要安装docker就可以一键部署，不由得心头一热，心动不如行动，那就干吧！

系统环境

  • Mac Monterey 12.6.1
  • Docker Desktop 4.15.0
  • docker 20.10.21
  • Docker Compose version v2.13.0

mysql

只需要将配置目录及数据目录做下映射即可

php

php需要开启一些常用扩展，所以需要在原始基础镜像上进行依赖安装或配置，Dockerfile如下：

              include        fastcgi_params;
          }

}

构建验证

docker-compose up

docker-compose 构建成功！

浏览器输入http://localhost phpinfo 成功访问！

最后

看了下docker的系统资源占用情况，真香！
