使用 uwsgi 和 nginx 设置 django

Question

我正在尝试使用 uwsgi 和 nginx 为 django 1.5 应用程序提供服务。以下是我的ini文件

[uwsgi]
# variables
projectname = mysite
projectdomain = mysite.in
base = /home/shwetanka/projects/me/mysite

# config
plugins = python
master = true
protocol = uwsgi
env = DJANGO_SETTINGS_MODULE=%(base)/%(projectname).settings
#pythonpath = %(base)/src/%(projectname)
module = %(base)/mysite/wsgi.py
socket = 127.0.0.1:8889
logto = %(base)/logs/uwsgi.log
#below line runs it as a daemon in background
daemonize = /var/log/uwsgi/mysite.log

我在日志中收到此错误 -

如何让它工作？

Answer 1

ImportError: 不支持按文件名导入。

--module 指令需要一个模块，而不是一个文件。你应该改用--wsgi-file。

Answer 2

您需要调用 django 模块：--module mysite.wsgi:application

别忘了添加：--env DJANGO_SETTINGS_MODULE=mysite.settings

例如，一个工作命令行是（假设您的当前目录是您的项目主目录）：

uwsgi --socket mysite/zohosel.sock  --module mysite.wsgi:application --env DJANGO_SETTINGS_MODULE=mysite.settings --home=/path/to/your/venv --chmod-socket=666

可以在the django docs website 上找到一些额外的信息和论据。
顺便说一句，这个tutorial on readthedocs对我帮助很大。

Answer 3

如果你能正确使用python manage.py runserver 0.0.0.0:8000，

然后在同一目录下运行uwsgi --http :8000 --module mysite.wsgi，mysite 是你的 django 项目的名称。
