python - 如何使用 Uwsgi？我的 python 主路径在哪里？

问题描述

我正在尝试使用 ec2 部署我的 django 应用程序。我遵循一些指示。

但是当我尝试连接 Uwsgi 和我的 django 应用程序时，出现了问题

(unifolio-back) ubuntu@ip-172-31-37-172:~$ which python
/home/ubuntu/.local/share/virtualenvs/unifolio-back-_HCbnSkq/bin/python

问题是什么？我猜python路径有问题......但我无法解决这个问题。

解决方案

Ubuntu 使用uwsgi基于插件的架构。为了成功运行 Python 3 应用程序，您需要该uwsgi-plugin-python3插件。首先，安装它apt：

$ sudo apt install uwsgi-plugin-python3

然后，将您的uwsgi命令更改为以下内容：

uwsgi --http :8080 --virtualenv /home/ubuntu/.local/share/virtualenvs/unifolio-back-_HCbnSkq \
      --chdir /srv/unifolio-back/ -w mysite.wsgi --plugins python3
