在 Heroku 上部署后 APP 运行即崩溃

[ARwMq9b6]

发现 Heroku 支持 WebSockets, 就在 Heroku 上部署了一个，可是 gost -ws 运行不起来， $ heroku logs 查看日志发现 gost 运行后崩溃，G 大是否有时间研究一下怎么在 Heroku 上运行 gost 呢？

Godeps.json 和 Procfile 都没问题，部署后 gost 一直尝试运行，但最终崩溃：

服务器端gost版本是多少，
崩溃后的日志信息可否发上来

[ARwMq9b6]

@ginuerzh 多谢 G 大的回复，服务端版本 1.7, 这是我 git push heroku master 部署时用的文件：https://copy.com/ZMjYfwGWiYyIAOEN/gost_heroku.7z

查看日志如下：

发现出错在 Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch ，好像说的是 gost -ws 后建立监听端口时发生错误。

搜到这篇文章 http://jamesmcfadden.co.uk/heroku-web-process-failed-to-bind-to-port-within-60-seconds-of-launch/ ，上面说 Heroku 每次开机都是随机端口， gost -L=":port" 这个端口必须是 Heroku 的环境变量中的 $PORT 值才行。

G 大可否帮助试验下 gost -L=":$PORT" -ws 是否可行。

[ginuerzh]

从日志及你所描述的情况来看，应该是端口限制导致的，
gost的默认监听端口是8080，你可以查看或设置一下$PORT变量，再通过-L参数设置此端口试试。

多谢 G 大，直接使用 $PORT:

$ gost -L=":$PORT" -ws

成功了……
