nginx.conf

server {
 listen       80;
 server_name  localhost;

 location / {
 root   /usr/share/nginx/html;
 index  index.html index.htm index.php;
 }

 error_page   500 502 503 504  /50x.html;
 location = /50x.html {
 root   /usr/share/nginx/html;
 }

 location ~ \.php$ {
 fastcgi_pass   php8:9000;
 fastcgi_index  index.php;
 fastcgi_param  SCRIPT_FILENAME  /html$fastcgi_script_name;
 include        fastcgi_params;
 }}

Important note

fastcgi_pass   php8:9000;

php8: The name of the php container. If you want to configure multiple php versions, you only need to copy the php configuration and fill in the corresponding php Container name

 php8: # php的容器名称
 image: php:8.0-fpm
 restart: always
 volumes:
 - ./nginx/html:/html--------------------------------
 php74: # 对应的nginx配置文件为：fastcgi_pass   php74:9000;
 image: php:8.0-fpm
 restart: always
 volumes:
 - ./nginx/html:/html

fastcgi_param  SCRIPT_FILENAME  /html$fastcgi_script_name;

/html: PHP project is mapped to [php container directory] (red)

docker-compose

version: '3.5'services:
 nginx:
 image: nginx:latest restart: always ports:
 - 8010:80
 volumes:
 - ./nginx/html/:/usr/share/nginx/html # 注意点一
 - ./nginx/conf/:/etc/nginx/conf.d/ links:
 - php8 php8:
 image: php:8.0-fpm restart: always volumes:
 - ./nginx/html:/html #注意点二

Note 1:

./nginx/html: Your php project address on this machine

/usr/share/nginx/html: nginx default access address

Note two:

./nginx/html: Your php project address on this machine

/html: The address here is to map your local php code to the php container. It is usually the same as the address configured by your nginx (red)

Tip: Please pay attention to two things The association of the red area, such a simple nginx php association environment has been configured successfully.

Pitfall guide:

When using -link, the custom port connecting to the container will be invalid, for example

version: '3.5'services:
 php8:
 image: php:8.0-fpm restart: always volumes:
 - ./nginx/html:/html links: # 如果使用 links ,当我们php程序中填写mysql端口的时候应该是 3306 而不是 3307，但是我们外部是需要用3307端口去连接mysql的
 - mysql mysql:
 image: mysql:latest ports:
 - 3307:3306
