无法在Webfaction上部署简单的Flask应用程序 [英] Can't deploy a simple Flask application on Webfaction

问题描述

我一直试图让Flask在我的webfaction服务器上工作几个小时，没有任何结果。

我按照 http：// flask.pocoo.org/snippets/65/

我有我的index.py文件存储在htdocs下。

  import sys 
 yourappname =/ home /< myusername> / webapps / myapp / htdocs
如果不是sys.path中的yourappname：
 sys.path.insert（0，yourappname）
 $ b $ from yourappname import app as application 
  

然后我把它添加到我的httpd.conf文件中：

  WSGIPythonPath / home / yourusername / webapps / yourapp / htdocs / 
＃如果你没有指定下面的指令，app *将会工作，但是你会在
中看到index.py URLs 
 WSGIScriptAlias / /home/yourusername/webapps/yourapp/htdocs/index.py 
 
<目录/ home / yourusername / webapps / yourapp / htdocs /> 
 AddHandler wsgi-script .py 
 RewriteEngine on 
 RewriteBase / 
 WSGIScriptReloading On 
< / Directory> 
  

然后我将myapp.py放在index.py旁边的htdocs目录中：

pre $ from flask import Flask
app = Flask（__ name__）

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

if __name__ =='__main__'：
app.run（）


我的域名指向了webfaction中的项目。默认的index.py在我覆盖之前正在工作，如说明中所述的那样。但是，我只得到服务器500.我很抱歉，但我是一个完整的noob当涉及到Linux和管理服务器。我甚至无法访问我的用户下的错误日志，因为它说我没有权限。

我认为这与我在linux服务器上安装烧瓶有关，我通过简单的安装来安装它，它说它安装了所有的依赖关系，并没有给出任何错误。

解决方案

几个建议：
$ b $ ol <

你不应该在你的index.py中有yourappname吗？另外，我假设你在`WSGIPythonPath / home / yourusername / webapps / yourapp / htdocs

中做了适当的替换你试过了吗？通过发行〜/ webapps /< app_name> / apache2 / bin / restart

重新启动Apache服务器

I have been trying to get Flask to work on my webfaction server for hours with no results.

I followed the instructions at http://flask.pocoo.org/snippets/65/

I have my index.py file stored under htdocs.

import sys
yourappname = "/home/<myusername>/webapps/myapp/htdocs"
if not yourappname in sys.path:
    sys.path.insert(0, yourappname)

from yourappname import app as application 

Then I have added this to my httpd.conf file:

WSGIPythonPath /home/yourusername/webapps/yourapp/htdocs/
#If you do not specify the following directive the app *will* work but you will
#see index.py in the path of all URLs
WSGIScriptAlias / /home/yourusername/webapps/yourapp/htdocs/index.py

<Directory /home/yourusername/webapps/yourapp/htdocs/>
   AddHandler wsgi-script .py
   RewriteEngine on
   RewriteBase /
   WSGIScriptReloading On
</Directory>

then i have myapp.py in the same htdocs directory next to index.py:

from flask import Flask
app = Flask(__name__)

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

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

I have my domain pointed to my project in webfaction. The default index.py was working prior to me overwriting with the new one as stated in the instructions. However, I only get the server 500. I apologize but I am a complete noob when it comes to linux and managing servers. I cannot even access my error log under users because it says I do not have permission.

I think that it has something to do with my installation of flask on the linux server, i installed it through easy install it says it installed all of the dependencies and did not give any errors.

解决方案

A couple of suggestions:

1. Shouldn't you have myapp everywhere you have yourappname in your index.py?
2. Also, I am assuming that you have made the appropriate substitutions in `WSGIPythonPath /home/yourusername/webapps/yourapp/htdocs
3. Have you tried restarting the apache server by issuing a ~/webapps/<app_name>/apache2/bin/restart
