EC2上的Python Flask應用程序AWS

我試圖在亞馬遜Linux AMI上運行簡單的python flask應用程序。我能夠顯示亞馬遜Linux AMI測試頁面，但是當我嘗試創建適當的配置來運行我的應用程序時，我總是面臨同樣的問題。EC2上的Python Flask應用程序AWS

我app.py：

from flask import Flask 
app=Flask(__name__) 

@app.route('/') 
def home(): 
    return "Hello World!" 

if __name__ == "__main__": 
    app.run()

我app.wsgi：

import sys 
import site 
import os 
# Add virtualenv site packages 
site.addsitedir(os.path.join(os.path.dirname(__file__), '/env/lib/python2.7/site-packages')) 

activate_this = '/var/www/flaskapp/env/bin/activate_this.py' 
execfile(activate_this, dict(__file__=activate_this)) 

# Path of execution 
sys.path.insert(0,'/var/www/flaskapp') 

#import the app 
from app import app as application

和我的httpd.conf：

<VirtualHost *> 
    ServerName ec2.... 
    WSGIDaemonProcess app threads=5 home=/var/www/flaskapp/ python-path=/var/www/flaskapp/env/lib/python2.7 threads=1 

    DocumentRoot /var/www/flaskapp 

    WSGIScriptAlias//var/www/flaskapp/app.wsgi 
    <Directory /var/www/flaskapp> 
      WSGIProcessGroup app 
      WSGIApplicationGroup %{GLOBAL} 
      Order deny,allow 
      Allow from all 
    </Directory> 
</VirtualHost>

如果我看一下是什麼安裝在virtualenv機智pip凍結我得到這個：

click==6.6 
Flask==0.11.1 
itsdangerous==0.24 
Jinja2==2.8 
MarkupSafe==0.23 
Werkzeug==0.11.11

so Flask is installed。爲什麼我無法導入它？我做錯了什麼？

感謝

'WSGIDaemonProcess'的'python-path'輸入應指向'site-packages'目錄。 – Suever

如果我將python-path更改爲/var/www/flaskapp/env/lib/python2.7/site-packages我會從markupsafe import中得到：標記，轉義，soft_unicode ImportError：沒有名爲markupsafe的模塊 – Thomas

在EC2/EB，通過上傳zip文件部署通過控制檯燒瓶應用。保持燒瓶應用程序像一個普通的燒瓶應用程序在您的電腦上。我想AWS會自動處理WSGI。

只需做到以下幾點：

application = app = Flask(__name__) 
...... 
...... 
application.run()

這個主文件保存爲「application.py」

Zip和上傳通過AWS控制檯，它將運行。
