apache2 和 mod wsgi:目标 WSGI 脚本无法作为 Python 模块加载 [英] apache2 and mod wsgi : Target WSGI script cannot be loaded as Python module
问题描述
我正在尝试在 ubuntu 上的 apache2 上安装 mod_wsgi.所以我安装了 libapache2-mod-wsgi 包，我用 a2enmod 激活了他.
I am trying to install mod_wsgi on apache2, on ubuntu. So I install libapache2-mod-wsgi package, I activate him with a2enmod.
我有一个网站 (languageAnalyz)，我正在尝试与 mod_wsgi 一起使用.当我调用 localhost/languageAnalyz 时，出现错误 500.
I got a web site (languageAnalyz), that I am trying to use with mod_wsgi. When I call localhost/languageAnalyz, I got an error 500.
在 apache2 日志中，我可以看到:
In apache2 log, I can see this :

我在谷歌上搜索了这个错误，我找到了很多解决方案(大部分时间是针对 Django 项目的).我不明白的是，我需要创建一个 __init__.py 文件.我所做的，这是我的 __init__.py 文件:
I googled this error, and I find lot of solutions (most of the times for Django project).
What I undsertand, is that I need to create a __init__.py file.
What I did, here is my __init__.py file :
__all__ = ['app','get_size_dir','get_nbrf_dir','getStats'] #name of my functions
import index # my three python files
import analyz
import test-wsgi
在__all__列表中，这是三个文件中函数的名称.我只是想启动 test-wsgi.py，并得到相同的错误 500.
In the __all__ list, this is the name of the functions in the three files.
I am just trying to launch test-wsgi.py, and get the same error 500.
这是我的 test-wsgi.py 文件:
Here is my test-wsgi.py file :
import os,sys
sys.path.append(os.path.dirname(__file__))
from cgi import escape,parse_qs
from flup.server.fcgi import WSGIServer
def app(environ, start_response):
start_response('200 OK',[('Content-Type','text/plain; charset=utf-8')])
yield "hello world!"
WSGIServer(app).run()
怎么了?谢谢，
这是我的 apache2 conf:
Edit : here is my apache2 conf :
WSGIPythonPath /var/www/languageAnalyz
<VirtualHost *:80>
...
<Directory /var/www/languageAnalyz/>
Options +Indexes ExecCGI FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
Allow from all
DirectoryIndex index.py
SetHandler wsgi-script
</Directory>
...
</VirtualHost>
编辑之二:所以我试着按照我在 django doc 上阅读的内容去做.我将我的 apache2 conf 更改为:
Edit_bis : So I try to do as I read on django doc. I change my apache2 conf to :
WSGIPythonPath /var/www/languageAnalyz
<VirtualHost *:80>
...
WSGIScriptAlias /IPA /var/www/languageAnalyz/testwsgi.py
<Directory /var/www/languageAnalyz/>
Options +Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
Allow from all
DirectoryIndex testwsgi.py
</Directory>
...
</VirtualHost>
我重新启动了 apache2，我得到了同样的错误，之前还有一个:
I restart apache2, and I got the same error, and one more before :

编辑者:
好的，我刚刚成功启动了 testwsgi.py.我将我的应用程序功能更改为应用程序，并在最后添加了一些行:
Ok, I just successfully launch testwsgi.py. I change my app function into application, and I add some lines at the end :
if __name__ == '__main__':
from wsgiref.simple_server import make_server
server = make_server('localhost', 8080, application)
server.serve_forever()
我不知道为什么它有效，为什么它以前不起作用....现在我在打开文件时遇到了一些问题，包括它们的路径(配置文件或模板文件...)
I event don't know, why it's working, why it was not working before. ... And now I got some problem to open files, with their path (config files, or templates files ...)

[Sun Aug 25 13:10:51 2013] [error] [client 127.0.0.1] flangs=open('config/languages.yml')
我尝试使用绝对路径，它也不起作用......
I try with absolute path, it didn't work too ...
推荐答案
对于不同的文件，我遇到了同样的问题，并使文件世界可执行为我修复了它.在将范围缩小为您的问题后，您当然希望将其锁定到所需的用户:
I had the same problem for a differnt file and making the file world executable fixed it for me. You would of course want to lock it down to the required user after you have narrowed this down as your issue:
chmod a+x test-wsgi.py
