docker run --name nginx -p 8898:80 -d nginx:1.20.2-alpine

搭建php-fpm

docker container run --rm -d --name php-fpm -v /usr/local/nginx/html:/var/www/html php:7.4.27-fpm-alpine

删除nginx原容器,新建映射路径

docker container run --rm -d --name nginx -v /usr/local/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /usr/local/nginx/conf/conf.d:/etc/nginx/conf.d -v /usr/local/nginx/log:/var/log/nginx -v /usr/local/nginx/html:/usr/share/nginx/html --link php-fpm:php-fpm -p 8898:80 nginx:1.20.2-alpine

修改nginx配置文件

        fastcgi_index  index.php;                                     
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
