Question

我已经设置了nginx，fastcgi和django。通过fastcgi运行我的django项目：

python26 manage.py runfcgi host=127.0.0.1 port=8080 --settings=settings

当我访问http://127.0.0.1时，我可以看到正常的django 404，因为除了管理员之外我没有在我的django项目上设置所有内容。所以我尝试访问http://127.0.0.1/admin并返回502错误的网关错误。

我检查了日志，这是我发现的。有谁知道是什么导致了这个错误？

BTW我正在运行nginx07和django1.2。

我可以从你的日志中看到，即使连接'/'也被拒绝了，所以这与管理员没有任何关系。

尝试使用telnet连接到正确端口上的localhost，看看是否可以打开连接。我猜这个守护进程没有运行。

您还删除了python traceback，这对于确定进程可能崩溃的原因非常有帮助。

Nginx，FastCGI和Django连接拒绝错误
