Question

我正在摆弄Docker，试图在单独的Alpine容器上运行Nginx和PHP-FPM来设置Docker组合。我的设置位于https://github.com/sparkbuzz/lemp_docker的GitHub上，我的 docker-compose.yml 如下所示：

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，我可以看到由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进入两个正在运行的实例，似乎服务运行得很愉快，但是，端口9000上的明确的PHP-FPM从未被命中。

我非常接近，但不确定Nginx为何对PHP上游感到满意。 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交谈？

Answer 1

你在php-fpm配置中听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

在Docker Compose
