使用mod_wsgi在apach上部署燒瓶

我正在嘗試部署我在Apache服務器上構建的Flask Web應用程序。我在rasberry pi 3上使用rasbian（Jessie）OS。應用程序運行完美的燒瓶內置開發Web服務器，但nomatther我做什麼我還沒有設法將它部署在APACH，這是我做了什麼：使用mod_wsgi在apach上部署燒瓶

sudo apt-get update 
sudo apt-get -y install python3 ipython3 python3-flask 
sudo apt-get -y install apache2 
sudo apt-get -y install libapache2-mod-wsgi-py3

它不是一個簡單的像這樣的代碼（同樣的錯誤），即使工作：

from flask import Flask 

app = Flask(__name__) 

@app.route("/") 
def hello(): 
    return "Hello world!" 

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

我使用python 3.4.2。我沒有在虛擬環境中使用它。

的文件夾結構：

app.py是/var/www/Arduinoweb/Arduinoweb/app.py arduinoweb.wsgi是/var/www/Arduinoweb/arduinoweb.wsgi

我使虛擬主機arduinoweb.conf並重新啓動apach2服務。

你有沒有SElinux運行？ – seanmus

你在你所需的目錄中有'__init __。py'嗎？ – seanmus

如果應用程序在簡單的燒瓶開發服務器中工作可能是一種缺少__init__.py的方式？ –

一開始，這樣的：

<Directory /var/www/ArduinoWeb/ArduinoWeb> 
WSGIProcessGroup arduinoweb 
WSGIApplicationGroup %{GLOBAL} 
WSGIScriptReloading On 
Require all granted 
</Directory>

應該是：

<Directory /var/www/ArduinoWeb> 
WSGIProcessGroup arduinoweb 
WSGIApplicationGroup %{GLOBAL} 
Require all granted 
</Directory>

技術上這是錯誤會導致兩個問題。

第一個是Apache甚至不應該讓你使用那個WSGI腳本，因爲它沒有權限。看起來就像你的Apache配置中的其他地方一樣，當它不應該真正存在時，它可以廣泛訪問你的文件系統。

我也放棄了重新加載選項作爲默認設置，無論如何也不需要。

第二個是WSGI腳本不會在守護進程組的上下文中運行。這意味着代碼會以嵌入模式加載，並以Apache用戶身份運行。如果您的文件的權限是隻有pi用戶可以讀取它們，那麼它將無法訪問app模塊。

將SeverName作爲IP地址通常也是錯誤的。如果它正在工作，那麼它只會這樣做，因爲這是Apache配置中的第一個VirtualHost，所以當Apache無法正確命名基本虛擬主機匹配時，默認使用它。

無論如何，看看是否有幫助，否則提供運行的輸出：

ls -las /var/www/ArduinoWeb /var/www/ArduinoWeb/ArduinoWeb

所以可以查閱一下所有權/目錄的權限/文件。

嘗試你寫的，同樣的錯誤，我檢查了所有權/權限，一切都很好 –

所以你假設你明白什麼所有權/許可是正確的？ :-)希望看到他們驗證。您是否曾經檢查過SELinux是否被其他人詢問啓用？通常，如果在'/ var/www''下，即使啓用了SELinux，Apache也不應該訪問它。 –

感謝您的幫助..最終它似乎只是在wsgi腳本路徑中輸入錯誤：「/ var/www/ArduinoWeb/ArduinoWeb」而不是「/ var/www/Arduinoweb/Arduinoweb」。

現在它似乎工作正常。謝謝！！
