脚本宝典收集整理的这篇文章主要介绍了

Dockerfile构建PHP开发镜像:Alpine+Nginx+PHP7+Supervisor+Crontab+Laravel

脚本宝典小编觉得挺不错的,现在分享给大家,也给大家做个参考,希望能帮助你少写一行代码,多一份安全和惬意。

一、配置目录结构

1.1 crontabs

# do daily/weekly/monthly maintenance
# min   hour    day     month   weekday command
# *         *         *         *         *         /usr/bin/php /usr/share/nginx/html/artisan schedule:run >> /dev/null 2>&1

Tips:一般在生产环境都是负载均衡,定时任务是单独在一个容器执行,故此是注释掉的,需要单独在定时任务容器中打开即可。

2.1 nginx与php配置文件

Tips:由于php配置文件是监听的sock,默认情况下监听端口 9000。PHP-FPM使用Unix套接字,这避免了TCP的开销。
