如何使uwsgi与nginx和Django 1.7一起使用？

Question

这是我尝试的：

我在/etc/nginx/sites-available/有一个django.conf

upstream django {
    server unix:///tmp/uwsgi.sock;
}

server {
    listen              80;
    server_name         weasyprint.django.dev;
    charset             utf-8;
    error_log           /var/log/nginx/django-weasyprint.log;

    location / {
        uwsgi_pass      django;
        include         /etc/nginx/uwsgi_params;
    }
}

然后在sites-enabled执行sudo ln -s /etc/nginx/sites-available/django.conf

然后我重新启动了nginx。

我在/var/virtual/WebApps/virtualenvs/WeasyPrintProject创建了一个名为weasyprint_site的django文件夹

我在同一文件夹上使用了virtualenv，所以现在我的结构是这样的：

WeasyPrintProject
     |---------bin
     |---------include
     |---------lib
     |---------local
     |---------share
     |---------weasyprint_site
                      |------------db.sqlite3
                      |------------manage.py
                      |------------test.py
                      |------------uwsgi.ini
                      |------------weasyprint_site

然后我也将uwsgi.ini放到uwsgi.ini如您所见。

其内容是：

[uwsgi]

socket=/tmp/uwsgi.sock
chmod-socket=666
uid = www-data
gid = www-data

chdir=/var/virtual/WebApps/virtualenvs/WeasyPrintProject
module=weasy_print.wsgi:application
master=true
pidfile=/var/virtual/WebApps/virtualenvs/WeasyPrintProject/weasy_print.pid
vacuum=true

当我在/var/virtual/WebApps/virtualenvs/WeasyPrintProject/weasyprint_site ，

我跑

uwsgi --ini uwsgi.ini

我得到以下内容：

我有2个问题：

1. 除非执行Ctrl + C，否则我无法回到bash
2. 出现导入错误，提示没有名为weasy_print.wsgi的模块

我按照这里的指示

我为此特定项目的virtualenv是使用python 2.7.4，而我正在尝试运行django 1.7。 环境是Ubuntu 14.04

我如何使Django应用程序正常工作。

Answer 1

首先，您正在进入WeasyPrintProject，但是您的项目在WeasyPrintProject / weasyprint_site中。 您应该将chdir放入uwsgi.ini文件中的该目录。

其次，您的项目名称是weasyprint_site，而不是weasy_print，因此您应该改为调用模块weasyprint_site.wsgi:application 。

最后一个问题是：您应该在uwsgi.ini中指定虚拟环境的路径，因此uwsgi进程现在可以在其中找到应用程序所需的其他软件包。

要在不中断uwsgi服务器的情况下返回控制台，必须将其置于后台，通过分叉，守护进程或直接从init脚本启动。 我个人建议使用wsgi中内置的皇帝/封臣制度。

不建议将项目放在virtualenv目录中。
