gunicorn＆bottle設置爲heroku

Question

我在heroku上玩瓶子，想換一個更「生產」的WSGI服務器gunicorn。這裏是我的設置：

import os 
import bottle 
from bottle import route, run, template, request, static_file, error 

class StripPathMiddleware(object): 
    def __init__(self, app): 
     self.app = app 
    def __call__(self, e, h): 
     e['PATH_INFO'] = e['PATH_INFO'].rstrip('/') 
     return self.app(e, h) 

# ................................................................. # 

@error(404) 
def error404(error): 
    return template('view/404.tpl') 

app = bottle.app() 
run(app=StripPathMiddleware(app), server='gunicorn', host='0.0.0.0', port=int(os.environ.get("PORT", 5000)), debug=True, workers=3) 

這是我的Procfile：

web: gunicorn SimpleServer:app -w 3 

我試圖Procfile有和沒有設置的工人數量，所以在SimpleServer.py應用。

在本地機器，如果在應用程序我有工人= 3它只能和我沒有指定起點gunicorn工人：

(bottleServ)caerus@Artem:~/bottleServ$ gunicorn SimpleServer:app 
2013-02-02 23:23:48 [18133] [INFO] Starting gunicorn 0.17.2

2013-02-02 23:23:48 [18141] [INFO] Booting worker with pid: 18141 

但是有一個問題工頭開始，不要緊，我使用什麼設置我得到：

(bottleServ)caerus@Artem:~/bottleServ$ foreman start

任何想法，將不勝感激！ ）

Answer 1

您正在啓動gunicorn來運行應用程序，然後使用Bottle's 'run'來產生另一臺服務器（至少在Heroku上）。出現錯誤的原因是初始服務器端口5000，第二臺服務器無法訪問。嘗試運行你的瓶子應用程序（python SimpleServer.py）它應該創建服務器本身。另外，當你傳遞'app'進入運行時，http服務器產生你的應用程序的另一個副本（產生另一個gunicorn服務器），所以只需刪除它。

run(server='gunicorn', host='0.0.0.0', port=int(os.environ.get("PORT", 5000)), debug=True, workers=X) 

python SimpleServer.py 

應該是你所需要的。
