Nginx和PHP容器之间拒绝Docker连接

我正在使用从源图像和nginx官方图像编译的php-fprm创建一个集群,但是当我尝试运行一个phpinfo()文件时,nginx会返回以下错误:

*5 connect() failed (111: Connection refused) while connecting to upstream, client: 172.18.0.1, server: localhost, request: "GET /phpinfo.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "127.0.0.1:8000"

docker-compose.yml文件:

version: '2'
services:
  php:
    restart: always
    build: data/php
    image: php:7.1
    ports:
      - "9000:9000"
    expose:
      - 9000
    volumes:
      - ./app:/usr/share/nginx/html
  web:
    restart: always
    build: data/nginx
    image: nginx:1.10.2
    ports:
      - "8000:80"
    links:
      - php
    volumes:
      - ./data/nginx/vhost.conf:/etc/nginx/conf.d/default.conf
      - ./data/nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./app:/usr/share/nginx/html
      - ./data/log/nginx:/var/log/nginx

我检查了主机中的9000端口,netstat -an | grep :9000命令和端口是活动的:

tcp6       0      0 :::9000                 :::*                    OUÇA

每个容器都有自己的localhost

Nginx和PHP在两个不同的容器中运行,因此PHP不在localhost上运行(从Nginx的角度来看).

由于您的PHP容器名为"php",因此您不希望连接到此:

fastcgi://127.0.0.1:9000

fastcgi://php:9000

fastcgi_pass phpserver;

upstream phpserver {
    server php:9000
}

docker create network myapp

$ docker network ls
