问题:Uwsgi 作为服务运行时不会加载应用程序

我在 Centos 6 中设置了一个基本的烧瓶应用程序,所有内容都包含在一个文件(app.py)中。我可以使用命令uwsgi --ini myuwsgi.ini从文件夹目录中使用 uwsgi 运行该文件,并且一切正常。 ini文件的内容是:

[uwsgi]
http-socket    = :9090
plugin    = python
wsgi-file = /project/app.py
process   = 3
callable = app

但是我想设置它,以便每次服务器关闭或它自己出现的任何情况。当我尝试运行命令service uwsgi start时,日志显示未找到任何应用程序。该服务使用的ini文件是/etc/uwsgi.ini,我用我的ini文件替换了它。

如果有帮助,日志的转储如下:

如果有人能告诉我为什么当我在ini中指定位置和可调用时它找不到应用程序?

解答

尝试以下配置,让我知道它是否适合您:

[uwsgi]
callable = app
chdir = /path/to/your/project/
http-socket = :9090
plugins = python
processes = 4
virtualenv = /path/to/your/project/venv
wsgi-file = /path/to/your/project/app.py

您可能还需要添加 uid 和 gid 参数。

确保您已安装软件包 uwsgi-plugin-python:

apt-get install uwsgi-plugin-python
