你好,我有一个django应用程序。我的整个系统配置如下:python 3,django 1.11,eventlet 0.21.0。Eventlet is_monkey_patched问题错误
1)Nginx的作为上游服务器:
upstream proj_server {
server unix:///tmp/proj1.sock fail_timeout=0;
server unix:///tmp/proj2.sock fail_timeout=0;
}
2)监控制工人。有一个gunicorn工人:
[program:proj]
command=/home/vagrant/.virtualenvs/proj/bin/gunicorn -c /vagrant/proj/proj/proj/deploy/gunicorn.small.conf.py proj.wsgi:application
directory=/vagrant/proj/proj/proj/deploy
user=www-data
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/proj.log
3)这是一个gunicorn.small.conf内容:
bind = ["unix:///tmp/proj1.sock", "unix:///tmp/proj2.sock"]
pythonpath = "/vagrant/proj/proj/proj/deploy"
workers = 2
worker_class = "eventlet"
worker_connections = 10
timeout = 60
graceful_timeout = 60
4),这是proj.wsgi内容:
"""
WSGI config for proj project.
This module contains the WSGI application used by Django's development server
and any production WSGI deployments. It should expose a module-level variable
named ``application``. Django's ``runserver`` and ``runfcgi`` commands discover
this application via the ``WSGI_APPLICATION`` setting.
Usually you will have the standard Django WSGI application here, but it also
might make sense to replace the whole Django WSGI application with a custom one
that later delegates to the Django one. For example, you could introduce WSGI
middleware here, or combine a Django application with an application of another
framework.
"""
import eventlet
eventlet.monkey_patch()
from eventlet import wsgi
import django.core.handlers.wsgi
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "proj.settings")
# This application object is used by any WSGI server configured to use this
# file. This includes Django's development server, if the WSGI_APPLICATION
# setting points here.
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
# Apply WSGI middleware here.
# from helloworld.wsgi import HelloWorldApplication
# application = HelloWorldApplication(application)
所以,你可以看到有一个链:nginx作为一个上游服务器调用其中一个使用两个socket的gunicorn eventlet工人proj1.sock或proj2.sock。 请注意,根据eventlet文档,我尽可能早地尝试使用eventlet.monkey_patch()。最适合的地方是proj.wsgi首先由gunicorn调用。
但是看起来库并不是猴子修补的。
要检查这个我加入凸出/凸出/凸出/ __ init__.py下面的代码(由Django应用程序称为第一模块):
import eventlet
import os
print("monkey patched os is: " + str(eventlet.patcher.is_monkey_patched('os')))
print("monkey patched select is: " + str(eventlet.patcher.is_monkey_patched('select')))
print("monkey patched socket is: " + str(eventlet.patcher.is_monkey_patched('socket')))
print("monkey patched time is: " + str(eventlet.patcher.is_monkey_patched('time')))
print("monkey patched subprocess is: " + str(eventlet.patcher.is_monkey_patched('subprocess')))
then i issued **./manage.py check** and got that answer:
monkey patched os is: false
monkey patched select is: false
monkey patched socket is: false
monkey patched time is: false
monkey patched subprocess is: false
我在做什么错?
我使用主管,因为有很多服务器上的进程应该管理,不仅gunicorn。什么abou wsgi - 有道理。我会尝试你的建议,谢谢。 –
