使用 mod_wsgi 访问瓶子应用程序

Question

httpd.conf

Listen 8081
NameVirtualHost *:8081

<VirtualHost *:8081>
    ServerName ubuntu.com

    WSGIDaemonProcess kenobi user=www-data group=www-data processes=1 threads=5
    WSGIScriptAlias / /var/www/kenobi/app.wsgi

    <Directory /var/www/kenobi>
        WSGIProcessGroup kenobi
        WSGIApplicationGroup %{GLOBAL}
        Order deny,allow
        Allow from all
    </Directory>
</VirtualHost>

app.wsgi

import os, sys

# Change working directory so relative paths (and template lookup) work again
sys.path.append('/var/www/kenobi')
os.chdir(os.path.dirname(__file__))
print sys.path


import server
print "launching..."
application = server.launch()
print "done"

server.py（使用bottle框架实现rest api的脚本）

@route('/helloworld', method='GET')
def get_service_host_list():
    return("hello world")

def launch():
    print "attaching to server"
    run(host="192.168.45.111", port="8085", debug=True)
    #application = bottle.default_app()

所以上面的代码工作正常，除了它使用两个端口 - 8081 被 mod_wsgi 用来启动 server.py 和 server.py 监听的 8085 端口

我需要在 server.py 中进行哪些更改以便只使用端口 8081？ 我已经尝试过使用 application = bottle.default_app() 但每当我调用“helloworld”api 时，我都会在 apache2 error.log 中收到“500 Internal Server Error”和以下错误：

[Sat Aug 23 12:05:17 2014] [error] launching...
[Sat Aug 23 12:05:17 2014] [error] attaching to server
[Sat Aug 23 12:05:17 2014] [error] done
[Sat Aug 23 12:05:17 2014] [error] [client 192.168.42.135] mod_wsgi (pid=35700):     Exception occurred processing WSGI script '/var/www/kenobi/app.wsgi'.
[Sat Aug 23 12:05:17 2014] [error] [client 192.168.42.135] TypeError: 'NoneType' object     is not callable

求救！！！

哎呀，必须进行以下更改才能使此功能正常工作： 将 server.py 中的 def launch() 更改为

print "attaching to server"
application = bottle.default_app()

替换 app.wsgi FROM 中的以下内容

import server
print "launching..."
application = server.launch()
print "done"

到

print "launching..."
from server import application
print "done"
