背景

我有一个Apache服务的Django站点，在自己的虚拟主机中设置并使用mod_wsgi .

我希望将与此虚拟主机关联的所有错误记录到单个文件中 .

目前，一些错误正在发送到Apache的默认错误日志，而其他错误正在发送到我在虚拟主机中定义的错误 .

我很确定我已经将Django设置为通过我的Django设置中配置的 logging.StreamHandler 实例将 WARN ， ERROR 和 CRITICAL 错误传送到 sys.stderr . 我认为mod_wsgi将它传递给Apache，后者根据适用的 ErrorLog ， ErrorLogFormat 和 LogLevel 指令记录它 .

问题

  • 哪些设置/情况会导致错误转到另一个日志？

  • 是否可以统一我提供的各种错误？

  • 在哪里可以记录哪些错误有任何限制？

错误日志示例

/ var / log / apache2 / mysite_error.log ：

（由于在Django设置文件中为默认的Django Logger 有目的地设置了无效的日志级别“foo”而导致 . ）

此外，如果我使用 logger.error('some error message') 手动进行日志记录调用，它也会显示在此处 - 而不是像我期望的那样在虚拟主机的错误日志中 .

程序版本信息

  • Apache / 2.4.7（Ubuntu）使用mpm_worker（ apache2ctl -V ）

  • Django / 1.8.14（ pip freeze ）

  • mod_wsgi / 3.4（this的最后一个方法）

  • Python / 2.7.6（来自主Apache的启动日志 error.log ）
