在Apache和mod_wsgi下运行的Django应用程序在每个Ansible剧本执行后重新开始。
我的要求是运行多个playbooks并行运行。 后台线程（在服务器启动时创build）从文件系统中select一个可用的播放，并提交给一个线程池，以便并行运行
我的应用程序configuration如下所示：
<VirtualHost *:1234> SSLEngine On SSLCertificateFile <path to cert file> SSLCertificateKeyFile <path to key file> ServerName example <Location /> SSLRequireSSL </Location> WSGIDaemonProcess myapp user=user group=user WSGIProcessGroup myapp WSGIScriptAlias / /home/user/test-wsgi.py CustomLog /var/log/myapp/access.log vhost_combined </VirtualHost> 我的脚本flie
import os import sys import site # Add the site-packages of the chosen virtualenv to work with site.addsitedir('~/.virtualenvs/myapp/local/lib/python2.7/site-packages') # Add the app's directory to the PYTHONPATH sys.path.append('/home/user/workspace/myproject/') sys.path.append('/home/user/workspace/myproject/myapp/settings/') os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings.dev' # Activate your virtual env activate_env=os.path.expanduser("~/.virtualenvs/myapp/bin/activate_this.py") execfile(activate_env, dict(__file__=activate_env)) import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler()

下面的日志说我的剧本执行失败，并立即mod_wsgi重新启动我的应用程序。

为什么mod_wsgi重新启动我的应用程序，以及如何限制？
