apache&mod_wsgi&django部署多个项目

今天做好了第二个django项目，但在部署时出了一点小问题，在此记录一下。

1、mod_wsgi 3.4已经支持了部署多个项目，只需在httpd.conf中进行如下配置：

WSGIScriptAlias /website1 "D:website1django.wsgi"
<Directory "D:website1django.wsgi">
    Options ExecCGI
    Order deny,allow
    Allow from all
</Directory>

WSGIScriptAlias /website2 "D:website2django.wsgi"
<Directory "D:website2django.wsgi">
    Options ExecCGI
    Order deny,allow
    Allow from all
</Directory>

2、urls.py需要修改一下，如下：

from django.conf.urls import patterns, include, url

# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'cloudweb.views.home', name='home'),
    # url(r'^cloudweb/', include('cloudweb.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    # url(r'^admin/', include(admin.site.urls)),
    
    #url(r'^initos/$', 'cloudapp.views.initos'),
    url(r'^$', 'cloudapp.views.publish'),
    url(r'^submit/$', 'cloudapp.views.publish_submit'),
)

原来按照官方文档是这样设置的：

httpd.conf:
WSGIScriptAlias / "D:website1django.wsgi"
urls.py:
url('^website1/submit/$', 'cloudapp.views.publis_submit'),

3、如果碰到如下错误：

找到C:Python26libsite-packageswin32libpywintypes.py文件的114行，修改如下：

if sys.version_info < (3,0):
        pass
##        assert sys.modules[modname] is old_mod
##        assert mod is old_mod
    else:
        assert sys.modules[modname] is not old_mod
        assert sys.modules[modname] is mod
        # as above - re-reset to the *old* module object then update globs.
        sys.modules[modname] = old_mod
        globs.update(mod.__dict__)
