如何使uwsgi與nginx和Django 1.7一起使用？

Question

這是我嘗試的：

我在/etc/nginx/sites-available/有一個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執行sudo ln -s /etc/nginx/sites-available/django.conf

然后我重新啟動了nginx。

我在/var/virtual/WebApps/virtualenvs/WeasyPrintProject創建了一個名為weasyprint_site的django文件夾

我在同一文件夾上使用了virtualenv，所以現在我的結構是這樣的：

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

然后我也將uwsgi.ini放到uwsgi.ini如您所見。

其內容是：

[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

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

我跑

uwsgi --ini uwsgi.ini

我得到以下內容：

我有2個問題：

1. 除非執行Ctrl + C，否則我無法回到bash
2. 出現導入錯誤，提示沒有名為weasy_print.wsgi的模塊

我按照這里的指示

我為此特定項目的virtualenv是使用python 2.7.4，而我正在嘗試運行django 1.7。 環境是Ubuntu 14.04

我如何使Django應用程序正常工作。

Answer 1

首先，您正在進入WeasyPrintProject，但是您的項目在WeasyPrintProject / weasyprint_site中。 您應該將chdir放入uwsgi.ini文件中的該目錄。

其次，您的項目名稱是weasyprint_site，而不是weasy_print，因此您應該改為調用模塊weasyprint_site.wsgi:application 。

最后一個問題是：您應該在uwsgi.ini中指定虛擬環境的路徑，因此uwsgi進程現在可以在其中找到應用程序所需的其他軟件包。

要在不中斷uwsgi服務器的情況下返回控制台，必須將其置於后台，通過分叉，守護進程或直接從init腳本啟動。 我個人建議使用wsgi中內置的皇帝/封臣制度。

不建議將項目放在virtualenv目錄中。
