django代码更改时需要重启uWSGI吗? [英] Does uWSGI need to be restarted when Django code changes?

问题描述

我正在开发一个在 nginx 和 uWSGI 下运行的 Django 网络应用程序.当我部署新的 Django 代码(例如，settings.py)时，是否需要重新启动 uWSGI?如果是，为什么?

I'm working on a Django webapp that's running under nginx and uWSGI. When I deploy new Django code (e.g., settings.py), do I need to restart uWSGI? If so, why?

背景:我有一个场景，我更新了 settings.py 和其他一些代码并部署了它.直到我重新启动 uWSGI，我才看到 webapp 行为的变化.

Background: I had a scenario where I updated settings.py and some other code and deployed it. I did not see the changes in the webapp behavior until I restarted uWSGI.

推荐答案

是的，需要重启uWSGI进程.

Yes, you need to restart the uWSGI process.

Python 将编译后的代码保存在内存中，因此在进程重新启动之前不会被重新读取.django 开发服务器 (manage.py runserver) 主动监视文件的更改，但默认情况下其他服务器不会发生这种情况.如果你想在 uWSGI 中启用自动重新加载，touch-reload 和 py-auto-reloaduWSGI 参数可能会有所帮助.

Python keeps the compiled code in memory so it won't get re-read until the process restarts. The django development server (manage.py runserver) actively monitors files for changes, but that won't happen by default with other servers. If you want to enable automatic reloading in uWSGI, the touch-reload and py-auto-reload uWSGI arguments might help.
