我在 AWS EC2 Micro 实例上使用 Ubuntu 12.04.1，并尝试使用 uWSGI 和 nginx 设置简单的 Flask 应用程序。我在 uWSGI 配置方面遇到了一些奇怪的问题。
这是我的app.conf：
[uwsgi]
socket = /tmp/tmp.sock
plugins = python27
chdir = /home/ubuntu/app
pythonpath = ..
module = app:app
virtualenv = /home/ubuntu/.virtualenvs/app
uWSGI 在重启后没有创建套接字文件，如果我用 手动运行它uwsgi -i /etc/uwsgi/apps-enabled/app.conf，这里是日志：
*** Starting uWSGI 1.0.3-debian (64bit) on [Sat Mar 16 06:54:39 2013] ***

detected binary path: /usr/bin/uwsgi-core
*** WARNING: you are running uWSGI without its master process manager ***

The -s/--socket option is missing and stdin is not a socket.
但是当我添加-s参数时，一切都正常：
uwsgi -i /etc/uwsgi/apps-enabled/app.conf -s /tmp/tmp.sock

那么，似乎 uWSGI 忽略了socket应用程序配置文件中设置的选项？
这种情况只发生在 ini 格式的配置文件中 - 使用 XML 编写的相同配置则一切正常。看起来像是一个错误。
答案1
uWSGI 仅期望一些扩展，例如.ini，.xml...
将文件重命名app.conf为app.ini将解决问题。
