我使用4种不同语言运行Django == 1.10.4网站。他们每个人都有自己的域名。其中只有2或3个同时工作。一个或多个失败,出现此错误:
这是我杀死wsgi进程并第一次访问该页面后出现的错误:

每次重新加载页面后,我只收到此错误:

这是我的设置文件查找每个域的方式。
#settings_en.py
from base_settings import *
ALLOWED_HOSTS = ['127.0.0.1', '.example.com' ]
LANGUAGE_CODE = 'en-GB'
ROOT_URLCONF = 'myproject.base_urls'
SITE_ID = 18
#settings_pl.py
from base_settings import *
ALLOWED_HOSTS = ['127.0.0.1', '.example.com' ]
LANGUAGE_CODE = 'pl-PL'
ROOT_URLCONF = 'myproject.base_urls'
SITE_ID = 19
#settings_xx.py
...
这就是我的app.wsgi对每个域的看法
#english version
#!/usr/bin/python
import sys, os
sys.path.insert(0, '/var/www/user324/priv/venv/myvenv/lib/python2.7/site-packages') #virtualenv
sys.path.insert(0, '/var/www/user324/priv/mysourcecode') #sourcecode
os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings_en'
import django.core.wsgi
application = django.core.wsgi.get_wsgi_application()
#polish version
#!/usr/bin/python
import sys, os
sys.path.insert(0, '/var/www/user324/priv/venv/myvenv/lib/python2.7/site-packages')
sys.path.insert(0, '/var/www/user324/priv/mysourcecode')
os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings_pl'
import django.core.wsgi
application = django.core.wsgi.get_wsgi_application()
知道这里出了什么问题吗?
在我重新启动wsgi进程后,某些域正在运行,有些域无效。每个域都访问相同的源代码和相同的数据库。所以我认为源代码没有问题,因为那些直接运行的站点没有任何问题。
答案 0 :(得分:0)
这看起来不像Django问题,但是对mod_wsgi的配置错误 - 看起来您的应用程序可能在同一个解释器中运行并且存在冲突。
你的Apache / mod_wsgi是如何配置的?特别感兴趣的是,应该打开daemon mode并为每个站点分离守护进程。 (See that directive's docs.)
另外,我建议用Apache / mod_wsgi之外的其他东西来研究你的应用程序--Nginx + uWSGI是我的首选武器。
