docker Nginx PHP-FPM单机多站点布署的方法

网上尝试过各种方法，处理单机中单NGINX容器，单PHP-FPM容器布署多站点，均无法成功。

经过反思总结，目前共实施两种方法成功：

单Nginx，多PHP-FPM
单Nginx，单PHP-FPM

单Nginx，多PHP-FPM

docker-compose.yml

version: '2'
services:
  nginx-1.15.1:
    image: nginx:laster
    ports:
      - "80:80"
    volumes:
      - ./htdocs:/usr/local/nginx/html
      - ./etc/nginx/nginx.conf:/etc/nginx/nginx.conf:ro
      - ./etc/nginx/conf.d:/etc/nginx/conf.d
      - ./log/nginx:/var/log/nginx
    networks:
      - leoedu-network
  php-fpm-a:
    image: php-fpm:laster
    volumes:
      - ./htdocs/a.com:/var/www/html
    networks:
      - leoedu-network
  php-fpm-b:
    image: php-fpm:laster
    volumes:
      - ./htdocs/b.com:/var/www/html
    networks:
      - leoedu-network
networks:
  leoedu-network:
    driver: bridge

nginx配置文件：

server {
  listen    80;
  charset utf-8;
  server_name a.com;
  root /usr/local/nginx/html/a.com;
  index index.html index.htm index.php;
  error_log /var/log/nginx/a.com-error.log;
  access_log /var/log/nginx/a.com-access.log;
  location ~ .php$ {
    fastcgi_pass  php-fpm-a:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include    fastcgi_params;
  }
}

单Nginx，单PHP-FPM

docker-compose.yml

version: '2'
services:
  nginx-1.15.1:
    image: nginx:laster
    ports:
      - "80:80"
    volumes:
      - ./htdocs:/usr/local/nginx/html
      - ./etc/nginx/nginx.conf:/etc/nginx/nginx.conf:ro
      - ./etc/nginx/conf.d:/etc/nginx/conf.d
      - ./log/nginx:/var/log/nginx
    networks:
      - leoedu-network
  php-fpm-7.2.5:
    image: php-fpm:laster
    volumes:
      - ./htdocs:/var/www/html
    networks:
      - leoedu-network
networks:
  leoedu-network:
    driver: bridge

NGINX配置关键点在于：

astcgi_param SCRIPT_FILENAME /var/www/html/nick.com/$fastcgi_script_name;
