Question

由于我住在德国，我可以说＆＃34;早上好＆＃34;现在。它04:18:15我现在需要睡一觉。但也许你可以帮我解决这个问题。

这是我使用docker的第一步，我无法通过我的webbrowser（调用http://myproject.dev:8080/）到达本地symfony。

我在浏览器中收到502 Bad Gateway消息

这是我的

我有三张照片。这些都放在

   - Dockerfile
   - myproject.nginx.conf

我的Symfony安装（从symfony安装程序获取的默认symfony）可以在/ var / www / symfony下找到

在这个文件夹里面有一个文件：docker-compose.yml

         - "8080:80"
      depends_on:
         - phpfpm
         - symfony

我认为这都是必要的文件。但我必须做一些调整才能让我的symfony项目运行。我遇到了诸如“会话存储无法创建目录”之类的问题。所以我试图将“framework.session.save_path”的路径修改为/app/config.yml中的其他内容。但解决方案比这更简单。我必须注意为framework.session.save_path定义的文件夹存在。

在symfony默认情况下，这是“％kernel.root_dir％/ .. / var / sessions /％kernel.environment％”。所以我为这个文件夹做了一些chmod和chown。（还有缓存和日志文件夹）

创建文件夹/ var / www / myproject / var / sessions
chown www-data：www-data / var / www / myproject / var / sessions
chown www-data：www-data / var / www / myproject / var / cache
chown www-data：www-data / var / www / myproject / var / logs
chmod 775 / var / www / myproject / var / sessions
chmod 775 / var / www / myproject / var / cache
chmod 775 / var / www / myproject / var / logs

由于我在config.yml中使用了一些配置并且在此之后没有任何工作，我忘了清除缓存文件夹。所以在我清除了我的/ var / www / myproject / app / cache文件夹后，它工作了，我吓坏了。

我希望这有所帮助，我没有忘记我采取的步骤，以使我的系统运行。我想知道您的配置中是否有任何改进。我希望还有很多其他方法可以让这样的系统运行起来。
