我正在尝试使用uwsgi作为我的应用服务器将Django部署到Heroku（雪松堆栈）。
我已尝试过多次配置，我已成功用于专用服务器上的部署。然而，即使我在我的Procfile中使用$ PORT env变量，Heroku一直在抱怨uwsgi没有正在侦听正确的端口。
web: uwsgi --http :$PORT --home $HOME --ini conf/uwsgi.ini
（注意我已经尝试了一系列配置调整，这是我尝试过的最简单的一个，关于错误的PORT编号总是出现同样的错误。）
env = DJANGO_SETTINGS_MODULE=retargeting.settings
module = django.core.handlers.wsgi:WSGIHandler()

从日志的第一行可以看到，正确的端口正在传递给uwsigi。有关为什么这不起作用的任何想法？
答案 0 :(得分：3)
不要在heroku上使用--http。使用--http-socket。
第一个是代理解决方案，绑定在两个不同的端口上。
