在 Docker Compose 中连接 PHP-FPM 和 Nginx

Question

我正在摆弄 Docker，试图在单独的 Alpine 容器上设置 Docker 与 Nginx 和 PHP-FPM 运行的组合。我的设置在 https://github.com/sparkbuzz/lemp_docker 的 GitHub 上可用，我的 docker-compose.yml 看起来如下：

version: '3'
services:
  alpine_nginx:
    build: ./nginx
    container_name: alpine_nginx
    links:
      - alpine_php
    ports:
      - "80:80"

  alpine_php:
    build: ./php
    container_name: alpine_php
    ports:
      - "9000:9000"

我能够成功构建图像，当我在浏览器中访问 localhost 时，我可以看到 Nginx 提供的 index.html。但是，在尝试访问 phpinfo.php 时，我收到 502 - Bad Gateway 错误

我可以 docker exec -it ... /bin/ash 进入两个运行实例，看起来服务运行很愉快，但是，很明显 PHP-FPM 在端口 9000 上是从来没有打过。

这是我的控制台的一些反馈：

我很接近，但不确定为什么 Nginx 对 PHP 上游不满意。 Nginx配置如下：

server {
  listen 80;
  server_name localhost;

  location / {
    root /var/www/localhost/htdocs/;
    index index.html;
  }

  location ~* \.php$ {
    fastcgi_index index.php;
    fastcgi_pass alpine_php:9000;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME /var/www/$fastcgi_script_name;
    fastcgi_param SCRIPT_NAME $fastcgi_script_name;
  }
}

如何让 Nginx 与 PHP FPM 通信？

Answer 1

您在 php-fpm 配置中收听 127.0.0.1。

将此添加到 php/Dockerfile

RUN sed -i 's/127.0.0.1:9000/0.0.0.0:9000/g' /etc/php7/php-fpm.d/www.conf
