服务Django应用程序时uwsgi分段错误 [英] uwsgi segmentation fault when serving a django application

问题描述

我正在尝试将Django应用程序从一台服务器迁移到另一台服务器。该应用程序在旧服务器上运行良好。

I am trying to migrate a django application from one server to another. The application is working fine on the old server.

在新服务器上，使用Django的runserver时，该应用程序可以正常运行。

On the new server, the application works fine when used using Django's runserver.

要在uwsgi下测试Django应用程序，我使用了

To test the django application under uwsgi, I used

uwsgi --http :8000 --module mysite.wsgi

这将按预期打开django管理页面，但当我尝试登录时，uwsgi会遇到如下的分段错误错误。

This opens the django admin page as expected but as soon as I try to login, uwsgi gets a segmentation fault error which is as follows.

如果有人可以帮助您理解这意味着什么，以及如何解决，我将不胜感激。

Would greatly appreciate if anybody could help understand what this means, and how might I fix this.

推荐答案

当针对两个不同的openssl版本编译uwsgi和psycopg时，会发生此错误。
您有两个解决方案。

This error occurs when uwsgi and psycopg are compiled against two different openssl versions. You have two solution.

• 禁用django数据库配置的ssl（另一个答案的解决方案）


• 从源代码安装psyocpg2而不是wheel

要从源代码安装psyocpg2，您必须卸载前一个并尝试执行此操作

to install psyocpg2 from source you have to uninstall previous one and try this

pip uninstall psycopg2
pip install --no-binary :all: psycopg2
