我目前正在使用通过 Apache 托管在同一域(但在不同端口上提供服务)的两个 Django 应用程序(比如A
& )。B
我相信我的设置是正确的,但是我在两个站点上随机获得了 500 个。500 on A
(例如)主要发生在请求被服务之后B
(反之亦然)。
在检查错误日志(例如)时,我A
看到wsgiA
模块正在尝试访问其他方式也是,B 的 wsgi 引发了一个异常,抱怨缺少 A 的 settings.py 文件]。我不确定他们为什么要寻找其他设置文件,所有视图上的导入(用于 settings.py)都特定于各自的项目。B
settings.py
这是我的设置:
A
正在港口上送达8080
,B
正在港口上送达80
。
虚拟主机:
<VirtualHost *:8080>
ServerAdmin x@x.net
ServerName string1
Alias /static/ /home/PATH_TO_PROJECT_A/static/
<Directory /home/PATH_TO_PROJECT_A/static>

WSGIScriptAlias / /home/PATH_TO_PROJECT_A/wsgi.py
<Directory /home/PATH_TO_PROJECT_A>

</Files>
</Directory>
LogLevel warn

# All other files on B:80 (other than /APP_B are served normally
DocumentRoot /home/foo/public_html/xyz/public
</VirtualHost>
端口.conf:
NameVirtualHost *:8080
Listen 8080
Listen 80
<IfModule mod_ssl.c>
Listen 443
</IfModule>
<IfModule mod_gnutls.c>
Listen 443
</IfModule>
'A' 上的 wsgi.py:
import os, sys
sys.path.append('home/PATH_TO_PROJECT_A') #1
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "PROJECT_A.settings") #2
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
在 B 上完全相同,只是对第 1 行和第 2 行进行了更改。
例如,我从error.log
说中得到的错误来自A
:

如您所见A
,错误日志抱怨缺少B
' 。settings.py
求大神指点,不知道怎么回事。我不明白为什么一个应用程序会寻找另一个应用程序的 settings.py 文件来导入?
这两个应用程序都按预期工作和执行,但它们确实会在服务于 500 的随机请求时中断(如果我再次刷新,它们会被清除)。
谢谢!
