我看过互联网,包括StackOverflow,并且看到了类似的问题,但几个小时后我感到难过。

我可以添加任何人认为可能有用的信息。 我在DigitalOcean Droplet Ubuntu14.0.4中,在virtualenv中名为' sod22',使用Python3.4,Django1.8,Gunicorn19.4.5,nginx1.4.6 这是我在Bash中的错误输出:

(sod22) root@ShapeOfData2:~/.virtualenvs/sod22# gunicorn --bind    0.0.0.0:8000 sod22.wsgi:application

我已经使用netstat检查了可能在端口8000上运行的进程:

(sod22) root@ShapeOfData2:~/.virtualenvs/sod22# netstat -tulpn

我已杀死所有Gunicorn进程,但获得相同的行为。但是,使用不同的命令,我的控制台似乎会锁定'并且网页上仍然没有输出:

(sod22) root@ShapeOfData2:~/.virtualenvs/sod22# gunicorn sod22.wsgi:application
[2016-01-27 02:27:17 -0500] [25638] [INFO] Starting gunicorn 19.4.5
[2016-01-27 02:27:17 -0500] [25638] [INFO] Listening at: http://127.0.0.1:8000 (25638)
[2016-01-27 02:27:17 -0500] [25638] [INFO] Using worker: sync
[2016-01-27 02:27:17 -0500] [25641] [INFO] Booting worker with pid: 25641

此时没有光标可以尝试其他任何操作,此时不会杀死控制台。

Per Sayse的建议,我在杀死进程后检查了进程和结果。也许Python正在使用port:8000并在它被杀后不断刷新?请参阅下文,请注意,在该过程被终止后,我再次检查,然后再次运行:

提前致谢。当然,我并不是唯一经历过这种情况的人!
