Question

I'm trying to deploy a hello flask app to a raspberry pi using lighttpd fastCGI.

I followed the instructions on the http://flask.pocoo.org/docs/0.10/deploying/fastcgi/ to the best of my ability

Here is my flask app (/var/www/demoapp/hello.py)

UPDATE p SET GenreOrder = 1
FROM ProgramGenre p
JOIN Filmlager f ON p.ProgramID = f.ProgramID
JOIN Genre g ON p.GenreID = g.GenreID
WHERE f."Type"= g.GenreTitle;

And here is my .fcgi file (/var/www/demoapp/hello.fcgi)

$scope.initDate = function(){
  $scope.date = new Date();
}

$scope.initDate();

And here is what I added to my /etc/lighttpd/lighttpd.conf

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World From Flask Yeh!"

if __name__ == "__main__":
    app.run(host='0.0.0.0', port=5000)

I get a 404 Not Found error

By the way what is the /tmp/hello-fcgi.sock where do I get this file

Please help. I'm essentially trying to find a simple way to deploy flask on my raspberry pi web server. I have tried several methods. The fastcgi seemed to be the easiest. If there is an easier way then let me know please.

Thank you

Vincent

Answer 1

我认为问题在于你的hello.fcgi文件中导入了一个名为yourapplication的模块，但是你创建的烧瓶应用程序名为hello。

尝试更改此行：

from yourapplication import app 至 from hello import app

修改：此外 - 在测试时仔细检查您的网址 - 因为您的@app.route设置为根，您必须在您的网址中包含尾部斜杠，例如：

http://xxx.xxx.x.xx/hello.fcgi/

而不是

http://xxx.xxx.x.xx/hello.fcgi

首先，与c_tothe_k说的一样，您需要在yourapplication文件中将hello更改为hello.fcgi。

我发现烧瓶文件中的说明缺乏。它建议阅读此页面，我也是http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs_ModFastCGI#Troubleshooting

页面底部有一个示例lighttpd.conf

我遵循了Flask文档和上一页中的说明。我将.fcgi文件重命名为.py，如Lightty文档中所示。

如果您遵循此方法，则无需担心.sock文件。这是lighttpd使用UNIX套接字与FastCGI进程通信的旧方法。它只需要在这里，所以配置解析器不会被破坏。

我在lighttpd.conf中使用了以下内容。你的其他文件看起来不错。（注意，这会将您的应用置于/hello之下，而不是/。）

fastcgi.server = (
    "/hello" =>
    (
        "python-fcgi" =>
        (
         "socket" => "/tmp/fastcgi.python.socket",
         "bin-path" => "/var/www/demoapp/hello.py",
         "check-local" => "disable",
         "max-procs" => 1,
        )
    )
)
