python - Dokku + Tornado 应用程序 = 502 Bad Gateway

Question

我正在尝试与 dokku 交 friend 。我在 DigitalOcean 液滴上运行 dokku。

user@mypc:~$ cat Procfile 
web: python3 main.py

user@mypc:~$ git push dokku master

To dokku@myapp.ru:app
   d2cd6b3..7733adf  master -> master

虽然下载成功了，但是还是出现502错误

root@myserver:~# dokku run app ps aux
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root         1  0.0  0.2  17888  1496 ?        Ss+  08:41   0:00 /bin/bash /exec ps aux
root        13  0.0  0.2  15536  1128 ?        R+   08:41   0:00 ps aux

root@myserver:~# dokku logs app
[I 140324 08:41:37 main:75] Starting http server on localhost:5000

如果你直接运行应用程序，它成功启动了一个网络，但我仍然会得到 502 错误。

root@myserver:~# dokku run app python3 main.py
[I 140324 08:59:19 main:75] Starting http server on localhost:5000

所有环境变量拼写正确，以及应用程序运行时的情况。有什么想法吗？

Answer 1

比我想象的要容易得多。我绑定(bind)了 0.0.0.0

抱歉这个愚蠢的问题。
