使用Apache和Mod_wsgi的Flask Hello World仅在Webroot中显示文件
我正在尝试使用wsgi从Flask站点通过apache2运行基本的hello.py。这是我的代码：
/var/www/flask_dev/hello.py
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
return 'Hello World!'
if __name__ == '__main__':
app.run()
/var/www/flask_dev/start.wsgi
from hello import app as application
import sys
sys.stdout = sys.stderr
/etc/apache2/sites-available/flask_dev.conf
#Listen 80
ServerName example.com
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com
ServerAdmin webmaster@localhost
#ServerName example.com
WSGIDaemonProcess hello user=<myuser> group=<myusersgroup> threads=5 python-path=/var/www/flask_dev
WSGIScriptAlias / /var/www/flask_dev/start.wsgi
<Directory /var/www/flask_dev>
WSGIProcessGroup hello
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
</Directory>
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
</VirtualHost>
# vim: syntax=apache ts=4 sw=4 sts=4 sr noet
/ etc / hosts
127.0.0.1 example.com
在运行sudo a2ensite flask_dev和之后sudo service apache2 reload (or
restart)，www.example.com仅提供webroot中的文件。我已经检查了错误日志，看起来好像是mod_wsgi和mod_python正在启动。有人知道我还想念什么吗？

我现在可以从错误日志中看到消息，并且看起来我受Ubuntu上的https://bugs.launchpad.net/ubuntu/+source/libapache2-mod-
python/+bug/1073147的影响12.04。
稍后，我将尝试重新编译为正确的Python版本，以查看它是否可以解决错误。目前，虽然发生此错误，但在访问example.com时仍看到列出的文件。

编辑2 更新到13.04已解决了版本信息。现在，当我转到example.com时，我收到403禁止的错误。当我拖尾error.log时，我看到：
[Mon Jan 13 21:03:41.464815 2014] [:error] [pid 10999:tid 3014634304] [client 127.0.0.1:35067] Attempt to invoke directory as WSGI application: /var/www/flask_dev/
我尝试将其添加AddHandler cgi-script py到flask_dev.conf中，但这似乎也不起作用。
有人以前在WSGI应用程序中遇到过这种错误，并且知道解决方法吗？
提前致谢。
编辑3 所有源代码现在都可以使用
-
在/var/www/flask_dev/hello.wsgi中，您应该导入应用程序而不是屁股。其次，您不应该使用DocumentRoot存储脚本。DocumentRoot用于存储静态文件，因此它肯定会将它们列为文件，而永远不会将其作为脚本运行。
尝试使用
WSGIScriptAlias / /var/www/flask_dev/hello.wsgi <Directory "/var/www/flask_dev"> WSGIProcessGroup hello WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory>检查此页面。
