docker run -p 80:80 -d --name nginx -v /docker/nginx/default.conf:/etc/nginx/conf.d/default.conf -v /docker/www:/docker/www --privileged=true nginx
创建php-fpm 镜像
docker pull php:7.4-fpm
创建容器
docker run -p 9000:9000 -d --name php -v /docker/www:/docker/www --privileged=true php:7.4-fpm
说明:-p 9000:9000 :将容器的9000端口映射到主机的9000端口
-d 后台运行(守护进程)
--name php：将容器命名为php
-v 将主机中当前目录下的www挂载到容器的www目录

php-fpm 和nginx的ip地址是否一致
docker inspect php | grep "IPAddress"

"SecondaryIPAddresses": null,
