Nginx 调试日志级别
Nginx debugging logging levels
我按照 these 说明并在 nginx 中启用了错误日志。
我试图测试日志，我通过删除 for 循环末尾的 : 创建了一个语法错误。
尝试加载网站时，出现 500 内部服务器错误。
查看日志后，我对所看到的内容感到很迷茫。我目前将级别设置为 debug.
我该如何配置设置才能告诉我问题是语法错误？
这是错误日志尾部的示例：

1) 禁用 nginx 调试模式，它会吃掉你的硬盘。 Nginx 调试模式日志的目的是调试 nginx 本身，而不是你的应用程序错误。
2) 不要在错误的地方查找错误，nginx 错误日志与您的应用程序（烧瓶）/中间件（在您的情况下为 uwsgi）日志无关
