我在Intranet环境中部署django应用程序。我已经建立了一个测试服务器，一切都很好（在解决我的头部修复错误后）。
这次，我正在设置生产服务器并在配置完所有内容后，我收到错误500，这里是 httpd / logs / error_log ：

在检查功能之前我注意到的另一件事：
答案 0 :(得分：2)
RuntimeError：populate（）不可重入
根据我的经验，这通常意味着Django项目中存在错误。它很难定位。另外，不要忘记重启apache。
执行makemigrations时，我的4个应用中只有一个模型文件进行了迁移，就像只有一个应用程序一样
尝试将makemigrations指向特定应用：
python manage.py makemigrations appname
不要忘记之后应用迁移：
python manage.py migrate
答案 1 :(得分：0)
对于遇到此问题的每个人来说，它可以是任何东西，例如错误的django配置或de mod_wsgi。 在我的情况下，我需要使用--enable-shared标签构建python 3。
如果您也是这种情况，可以关注this。
