Question

基本hello.wsgi运行正常。其他django应用程序完美与绝对相同的virtualenv版本。

mod_wsgi挂起约10分钟（!!!），我发现没有什么可以指出我的问题（loglevel debug）：

Apache配置也没有任何有趣的内容。相同的配置适用于其他服务器。

<VirtualHost *:80>
    ServerName prj-dev
    ServerAdmin admin@force.fm
    DocumentRoot "/var/www/prj.project-dev/venv/www/public"
    ErrorLog /var/log/apache2/prj.project-dev/error_log
    CustomLog /var/log/apache2/prj.project-dev/access_log common

    Alias /media/ /var/www/prj.project-dev/venv/prj/prj/media/
    Alias /static/ /var/www/prj.project-dev/venv/prj/prj/static/
    Alias /usermedia/ /var/www/prj.project-dev/venv/prj/prj/usermedia/

    <Directory /var/www/prj.project-dev/venv/prj/prj/usermedia>
        Order deny,allow
        Allow from all
    </Directory>

    <Directory /var/www/prj.project-dev/venv/prj/prj/media>
        Order deny,allow
        Allow from all
    </Directory>

    <Directory /var/www/prj.project-dev/venv/prj/prj/static>
        Order deny,allow
        Allow from all
    </Directory>

    WSGIDaemonProcess prj.project-dev user=user group=user processes=2 threads=2 display-name=%{GROUP}
    WSGIProcessGroup prj.project-dev
    WSGIScriptAlias / /var/www/prj.project-dev/venv/www/public/index.wsgi

    XSendFile on

    <Directory /var/www/prj.project-dev/venv/www/public>
        Order deny,allow
        Allow from all
    </Directory>

</VirtualHost>

wsgi：

没什么有趣的

import os, sys

activate_this = '/var/www/prj.project-dev/venv/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))
sys.path = [
    '/var/www/prj.project-dev/venv/lib/python2.7/site-packages/',
    '/var/www/prj.project-dev/venv/prj/',
    '/var/www/prj.project-dev/venv/',
] + sys.path

os.environ['DJANGO_SETTINGS_MODULE'] = 'prj.settings'

import django.core.handlers.wsgi
#from raven.contrib.django.middleware.wsgi import Sentry

application = django.core.handlers.wsgi.WSGIHandler()
#application = Sentry(django.core.handlers.wsgi.WSGIHandler())

我的问题是：我怎样才能找到它挂起的真正原因？

Answer 1

mod_wsgi文档涵盖了这一点。

http://code.google.com/p/modwsgi/wiki/ApplicationIssues#Python_Simplified_GIL_State_API

简而言之，您可能正在使用Python扩展模块，该模块未实现在Python子解释器中正常工作。在执行阻塞操作时，该扩展模块或扩展模块未正确释放GIL。两者都可能导致解释器死锁。

使用文档中的解决方案，看看是否有帮助。

Answer 2

<VirtualHost *:80>
    ServerName localhost
    ServerAlias localhost
    ServerAdmin raghav@xyz.com

    <Directory /var/www/mysite/mysite>
    AddHandler wsgi-script .py
    Options +ExecCGI
    </Directory>

    DocumentRoot /var/www/mysite
    WSGIDaemonProcess myproject python-path=/var/www/mysite:/var/www/environ/lib/python2.7/site-packages
    #WSGIProcessGroup mysite
    WSGIScriptAlias / /var/www/mysite/mysite/wsgi.py

    WSGIApplicationGroup %{GLOBAL}

    <Directory /var/www/mysite/mysite/>


    order deny,allow
    Allow from all
    </Directory>

我也遇到了同样的错误，我使用此配置解决了这个问题。

同时将以下行添加到/etc/apache2/apache.config

#WSGIPythonPath /var/www/mysite

Answer 3

我知道这个帖子已经三年了，但是当我遇到类似的问题时，我偶然发现了它，所以我想我会添加我的解决方案。在我的情况下，虚拟环境中的某些东西需要在Apache中启用mod_ssl，即使这些站点都没有使用SSL（他们这样做但是它在其他地方终止）。所以

a2enmod ssl
service apache2 restart

修正了它。

Answer 4

在深入了解上述答案之后。我必须将进程数从5设置为1.还使用多工作程序mpm。

LoadModule mpm_worker_module modules/mod_mpm_worker.so
WSGIDaemonProcess music user=apache group=apache processes=1 threads=30  python-path=/srv/www/music/service/venv/lib/python2.7/site-packages
