使用Nginx和Linux进行多个Django站点设置Gunicorn

Question

我需要在我的服务器上运行多个Django项目。在我尝试在不同的端口（8000/8001）上运行Gunicorn后，我尝试了this thread。我假设它不起作用，因为我的Django项目位于不同的虚拟环境中。

要开始使用Gunicorn，我在不同的虚拟环境中运行了manage.py run_gunicorn -b 0.0.0.0:8000和manage.py run_gunicorn 0.0.0.0:8001。

在端口8001上运行第二个Gunicorn deamon并在Nginx中为我的第二个域添加V-Host后，在我的浏览器中打开URL打开了第一个网站。我重新启动了我的服务器并尝试在端口8001上为第二个站点运行Gunicorn，然后我从Nginx得到了502错误，所以我假设问题与Nginx有关。

Nginx V-Hosts
