在Docker Compose中將PHP-FPM與Nginx連接

Question

我不喜歡Docker，嘗試通過在單獨的Alpine容器上運行的Nginx和PHP-FPM設置Docker組合。 我的設置可在GitHub上的https://github.com/sparkbuzz/lemp_docker上獲得 ，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"

我能夠成功構建映像，並且當我在瀏覽器中訪問localhost時，可以看到Nginx提供的index.html。 但是，當嘗試訪問phpinfo.php時，出現502- 錯誤的網關錯誤

我可以在兩個正在運行的實例中都使用docker exec -it ... /bin/ash ，看來服務運行得很順利，但是很明顯，端口9000上的PHP-FPM從未被使用過。

以下是來自我的控制台的一些反饋：

我很親近，但不確定為什么Nginx對上游的PHP不滿意。 Nginx的配置如下：

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;
  }
}

我如何讓Nginx與PHP FPM對話？

Answer 1

您正在php-fpm配置中收聽127.0.0.1 。

將此添加到php/Dockerfile

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