SECRET_KEY 使用 uWSGI 的 Django 出错

Question

我正在尝试运行带有 uWSGI 的 Python 3 Django 应用程序，但遇到了麻烦。

我运行 uWSGI作为守护进程：

$ sudo service uwsgi start

我正在使用如下文件： [uwsgi]

chdir = /home/ubuntu/my_app
module = my_app.wsgi
# path below is to virtual environment
home = /home/ubuntu/my_app/env 
http = :8000
check-static = /var/www/my_app
daemonize = /var/log/uwsgi/my_app

# process-related settings
master = true
processes = 10
vacuum = true

我收到以下令人费解的错误：

mapped 800360 bytes (781 KB) for 10 cores
*** Operational MODE: preforking ***
Traceback (most recent call last):
  File "./titlematch_api/wsgi.py", line 14, in <module>
    application = get_wsgi_application()

  File "./titlematch_api/settings.py", line 20, in <module>
    SECRET_KEY = os.environ['SECRET_KEY']
  File "/usr/lib/python3.4/os.py", line 631, in __getitem__
    raise KeyError(key) from None
KeyError: 'SECRET_KEY'

我已经为我的当前用户和 root 设置了 SECRET_KEY 环境变量，我可以在 python shell 中成功执行 os.environ['SECRET_KEY']。

Answer 1

你不能真正做到这一点，因为你的环境是在本地 ~/.bashrc 中设置的，uwsgi 无法访问它。

您可以将变量放在 /etc/rc.local 中，但我什至不确定这是否有效

您可以将它们添加到您的文件中

[uwsgi]
chdir = /home/ubuntu/my_app
module = my_app.wsgi
# path below is to virtual environment
home = /home/ubuntu/my_app/env 
http = :8000
check-static = /var/www/my_app
daemonize = /var/log/uwsgi/my_app

# process-related settings
master = true
processes = 10
vacuum = true

#environment
env=SECRET_KEY="My Super Secret Key"

或者您可以直接在 python 文件中的应用程序对象上配置它

app = Flask(__name__)
app.secret_key="My Super Secret Key"

坦率地说，我可能会这样做

Answer 2

在你的 uwsgi ini 配置中： env = SECRETKEY=$(SECRETKEY) ^^^ 这将指示 uwsgi 获取 SECRETKEY env var 并确保在它创建的分叉进程中设置它
