利用官方镜像+Dockerfile构建符合自己要求php7.4镜像

DockerFile

• apt官方源太慢时，切换apt源
• 该dockerfile支持的php额外扩展 bcmatch event exif gd mysqli iconv pcntl pdo_mysql redis sockets opcache
• 来源 php:7.4.33-fpm

同级目录的 sources.list文件，需要切换apt源时使用

#http://mirrors.163.com/debian/为软件源也可以为其他的 bullseye为版本代号 main non-free contrib区别如下deb http://mirrors.163.com/debian/ bullseye main non-free contribdeb http://mirrors.163.com/debian/ bullseye-updates main non-free contribdeb http://mirrors.163.com/debian/ bullseye-backports main non-free contribdeb-src http://mirrors.163.com/debian/ bullseye main non-free contribdeb-src http://mirrors.163.com/debian/ bullseye-updates main non-free contribdeb-src http://mirrors.163.com/debian/ bullseye-backports main non-free contrib#deb http://mirrors.163.com/debian-security/ bullseye/updates main non-free contrib#deb http://mirrors.ustc.edu.cn/debian-security/ bullseye/updates main non-free contrib#deb-src http://mirrors.163.com/debian-security/ bullseye/updates main non-free contrib#deb-src http://mirrors.ustc.edu.cn/debian-security/ bullseye/updates main non-free contribdeb http://mirrors.ustc.edu.cn/debian-security/ stable-security main non-free contribdeb-src http://mirrors.ustc.edu.cn/debian-security/ stable-security main non-free contrib

Docker-compose

• 挂载文件php.ini php-fpm.conf
• stdin_open与 tty 用于执行常驻脚本
• 构建后镜像名称 php:7.4-local
• fpm reload 宿主机指令： docker exec php kill -USR2 1
• cli 宿主机指令 docker exec php php ${WWW_DIR}/cli.php 
• .env配置 WWW_DIR挂载项目路径
• docker-compose up  首次启动会构建镜像
