使用uWSGI的Django的SECRET_KEY錯誤

Question

我正在嘗試使用uWSGI運行Python 3 Django應用程序，並且遇到了麻煩。

我將uWSGI作為守護程序運行：

$ 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

我收到以下令人費解的錯誤：

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>

  File "/usr/lib/python3.4/os.py", line 631, in __getitem__
    raise KeyError(key) from None
KeyError: 'SECRET_KEY'

我已經為當前用戶和root用戶設置了SECRET_KEY環境變量，並且可以在python shell中成功執行os.environ['SECRET_KEY'] 。

Answer 1

您無法真正做到這一點，因為您的環境是在uwsgi無法訪問的本地〜/ .bashrc中設置的。

您也許可以將變量放在/etc/rc.local但是我什至不確定它是否可以工作

您可以將它們添加到您的文件中

[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app對象上配置它

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

坦率地說，這可能是我會這樣做的方式

Answer 2

在您的uwsgi ini配置中： env = SECRETKEY=$(SECRETKEY) ^^^這將指示uwsgi使用SECRETKEY env var並確保在它創建的分叉進程中對其進行了設置
