python – Django – 部署与Gunicorn,Nginx和主管,Gunicorn错误日志

我和Gunicorn Nginx Supervisor一起部署了一个Django 1.6应用程序.一切正常,但我有Gunicorn error.log一直发送错误.该文件很大,每秒都会向日志文件发送错误.

来自Gunicorn的错误.log：

任何导致Gunicorn日志文件错误的线索？正如我所说的一切正常运作没有问题.唯一的问题是这个日志不断发送错误.

最好的祝福,

最佳答案

这通常发生在gunicorn进程重试几次并且如果你碰巧在端口上开始一个进程(在你的情况下为8000)而前一个proc即将完成等等.因此,您需要单独终止所有此类进程.

>您可以使用netstat -tulpn查看PID
> kill -9 PID

其他等待过程将在循环等待情况下自动启动.所以反复检查netstat并杀死它们直到找不到该端口上运行的进程.

Gunicorn流程在这一点上应该可以正常工作.
