# Virtual Hosts
#
# Required modules: mod_log_config

# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at 
# <URL:http://httpd.apache.org/docs/2.4/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.

django 目录如下:

error的log如下:

django的wsgi.py如下:

It exposes the WSGI callable as a module-level variable named ``application``.

from os.path import dirname, abspath

from django.core.wsgi import get_wsgi_application

import sys

PROJECT_DIR = dirname(dirname(abspath(__file__)))
sys.path.insert(0,PROJECT_DIR)

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "visualplat.settings")

application = get_wsgi_application()

Answer 1

先把所有apache和uwsgi都关闭，开始排查问题

1、先排除django的环境问题, 看看程序有没有什么包没装

python manage.py runserver 0.0.0.0:5090

2、如果顺利运行，则访问http://ip:5090看看是否能正常访问

3、如不能正常访问检查一下防火墙是开着还是关了，如果是开着看看端口是否已加入

以上问题都通过，再去开uwsgi及ahache的配置问题

Answer 2

这种情况我也遇到过，是python的问题，不是apache的问题。
