Python Django、Virtualenv、nginx和x2B；uwsgi导入模块wsgi错误

我正试图用nginx、virtualenv和uwsgi在一个登台服务器上设置我的django项目，但我一直收到一个导入模块wsgi错误

如果有一个社区，我可以在这里找到答案。。。提前谢谢大家

这是我的配置文件：

我的django项目的uwsgi.py：

import os
import sys 
import site

site.addsitedir(os.path.join(os.environ['WORKON_HOME'],'project/lib/python2.6/site-packages'))
sys.path.append(os.path.abspath(os.path.dirname(__file__)))
sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../../'))
sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../'))

os.environ['DJANGO_SETTINGS_MODULE'] = 'project.configs.staging.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

project
|-manage.sh -> this fellow is redirected to settings.py (production, common or staging)
|-requirements.txt
|-README
|-dashbard.py
|-project.sqlite
|- project/
    |- apps
        |- accounts
        |-other internal apps
    |- configs 
        |- common -> for local development
            |-settings.py
            |-manage.py
            |-urls
        |-staging
            |-manage.py
            |-settings.py
            |-wsgi.py
            |-logging.conf
        |-production
            |-manage.py
            |-settings.py
            |-wsgi.py
            |-logging.conf
    |-media
    |-templates

Nginx配置

# nginx configuration for project.maumercado.com

server {
    server_name project.maumercado.com;
    access_log /home/ubuntu/logs/project/nginx/access.log;
    error_log /home/ubuntu/logs/project/nginx/error.log;

    location / {
            uwsgi_pass unix:/tmp/uwsgi.sock;
            include /etc/nginx/uwsgi_params;
    }

    location /static {
            root /home/ubuntu/django-projects/project/project/media;
    }
    location /media {
            root /home/ubuntu/django-projects/project/project/media;
    }
}

还有，我的uwsgi.conf

# file: /etc/init/uwsgi.conf 
description "uWSGI starter"

start on (local-filesystems and runlevel [2345])
stop on runlevel [016]

respawn

# home - is the path to our virtualenv directory
# pythonpath - the path to our django application
# module - the wsgi handler python script

exec /home/ubuntu/ve/project/bin/uwsgi \
--uid www-data \
--pythonpath /home/ubuntu/django-projects/project/project/configs/staging/ \
--socket /tmp/uwsgi.sock \
--chmod-socket \
--module wsgi \
--logdate \
--optimize 2 \
--processes 2 \
--master \
--logto /home/ubuntu/logs/project/uwsgi.log

Nginx日志在access.log中除了500之外没有任何声明，因此这里是uwsgi.log：

我不知道我设置项目的方式是否与此有关，但无论如何，下面是我用来重定向django实用程序的管理文件：

manage.sh

#!/bin/bash

python ./project/configs/${DEPLOYMENT_TARGET:="common"}/manage.py $*

以防万一，我就是这样建立了一个django项目的：

import os
import sys 
import site

site.addsitedir(os.path.join(os.environ['WORKON_HOME'],'project/lib/python2.6/site-packages'))
sys.path.append(os.path.abspath(os.path.dirname(__file__)))
sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../../'))
sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../'))

os.environ['DJANGO_SETTINGS_MODULE'] = 'project.configs.staging.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

project
|-manage.sh -> this fellow is redirected to settings.py (production, common or staging)
|-requirements.txt
|-README
|-dashbard.py
|-project.sqlite
|- project/
    |- apps
        |- accounts
        |-other internal apps
    |- configs 
        |- common -> for local development
            |-settings.py
            |-manage.py
            |-urls
        |-staging
            |-manage.py
            |-settings.py
            |-wsgi.py
            |-logging.conf
        |-production
            |-manage.py
            |-settings.py
            |-wsgi.py
            |-logging.conf
    |-media
    |-templates

确保将包含wsgi.py文件的目录添加到pythonpath（您可以指定一系列不受限制的pythonpath指令）

我更新了wsgi.py，如下所示：

import os
import sys
import site

site.addsitedir(os.path.join('/home/ubuntu/ve','project/lib/python2.6/site-packages'))
sys.path.append(os.path.abspath(os.path.dirname(__file__)))
sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../../'))
sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../'))

os.environ['DJANGO_SETTINGS_MODULE'] = 'project.configs.staging.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

# file: /etc/init/uwsgi.conf
description "uWSGI starter"

start on (local-filesystems and runlevel [2345])
stop on runlevel [016]

respawn

exec /home/ubuntu/ve/project/bin/uwsgi \
--uid ubuntu \
--pythonpath /home/ubuntu/django-projects/project/project/configs/staging \
-H /home/ubuntu/ve/project \
--socket /tmp/uwsgi.sock \
--chmod-socket 644 \
--module wsgi \
--logdate \
--optimize 2 \
--processes 2 \
--master \
--logto /home/ubuntu/logs/project/uwsgi.log

# file: /etc/nginx/sites-available/yourdomain.com
# nginx configuration for project.maumercado.com

server {
        listen 80;
        charset utf-8;
        server_name project.maumercado.com;
        access_log /home/ubuntu/logs/project/nginx/access.log;
        error_log /home/ubuntu/logs/project/nginx/error.log;

        location ^~ /cache/ {
                root /home/ubuntu/django-projects/project/project/media;
                expires max;
        }

        location / {
                uwsgi_pass unix:/tmp/uwsgi.sock;
                include /etc/nginx/uwsgi_params;
        }
}

我的uwsgi.conf文件现在如下所示：

import os
import sys
import site

site.addsitedir(os.path.join('/home/ubuntu/ve','project/lib/python2.6/site-packages'))
sys.path.append(os.path.abspath(os.path.dirname(__file__)))
sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../../'))
sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../'))

os.environ['DJANGO_SETTINGS_MODULE'] = 'project.configs.staging.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

# file: /etc/init/uwsgi.conf

stop on runlevel [016]

respawn

        }

        location / {
                uwsgi_pass unix:/tmp/uwsgi.sock;
                include /etc/nginx/uwsgi_params;
        }
}

我的nginx站点可用文件如下所示：

import os
import sys
import site

site.addsitedir(os.path.join('/home/ubuntu/ve','project/lib/python2.6/site-packages'))
sys.path.append(os.path.abspath(os.path.dirname(__file__)))
sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../../'))
sys.path.append(os.path.join(os.path.realpath(os.path.dirname(__file__)), '../../'))

os.environ['DJANGO_SETTINGS_MODULE'] = 'project.configs.staging.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

        error_log /home/ubuntu/logs/project/nginx/error.log;

        location ^~ /cache/ {
                root /home/ubuntu/django-projects/project/project/media;
                expires max;
        }

        location / {
                uwsgi_pass unix:/tmp/uwsgi.sock;
                include /etc/nginx/uwsgi_params;
        }
}

现在它的工作非常完美，我对样式有一些问题，因为css文件中使用了像ñ这样的奇怪字符

现在我想知道，当我需要在同一台服务器上运行更多的项目时，我应该怎么做？

--pythonpath/home/ubuntu/django projects/project/project/configs/staging/不应该是/home/ubuntu/django projects/project/project\u apps/configs/staging而不是/home/ubuntu/django/django projects/projects/configs/staging？哦，我明白了信息技术是的，实际上就是这样，我在那里设置的“project\u apps”文件夹实际上叫做project，我会编辑它！我对多个项目所做的是使用uwsgi Debian包。它附带init脚本、一些默认的.ini设置文件，并管理每个项目。您只需要为每个文件配置一个配置，为每个文件配置一个不同的套接字（默认情况下进行处理），它们将在同一个系统上很好地运行。即使您不在Debian上，也可以使用Debian软件包中的init脚本和配置布局：
