Question

我试图使用Supervisor和Gunicorn在Debian服务器上启动Django项目。当我运行命令＆＃34; sudo supervisorctl start gunicorn＆＃34;时，我收到以下错误：

Traceback (most recent call last):

ImproperlyConfigured: Set the MEDIA_ROOT environment variable
[2016-01-27 19:39:31 +0000] [30408] [INFO] Worker exiting (pid: 30408)

我的base.py基本设置文件读取我在＆＃34; hash1＆＃34;中设置的环境变量。虚拟环境的postactivate hook：

# base.py
def get_env_variable(var_name):
    try:
        return os.environ[var_name]
    except KeyError:
        error_msg = "Set the %s environment variable" % var_name
        raise ImproperlyConfigured(error_msg)
# The rest of my settings...

我已经确认＆＃34; NotperlyConfigured＆＃34;此功能在设置文件中生成错误消息。

以下是我的主管和gunicorn文件：

# /etc/supervisor/conf.d/supervisor.conf
[program:gunicorn]
command=/srv/http/example.com/repo/bin/start-gunicorn
directory=/srv/http/example.com/repo
user=root
environment=MEDIA_ROOT="/var/www/swing/media/"

# start-gunicorn
#!/bin/bash
NAME=example
DJANGODIR=/srv/http/example.com/repo
USER=smith
GROUP=smith
WEBSITE=$NAME
NUM_WORKERS=3
DJANGO_SETTINGS_MODULE=conf.settings.prod
DJANGO_WSGI_MODULE=conf.wsgi

cd /home/smith/venvs/current/bin
source activate
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DJANGODIR:$PYTHONPATH

exec gunicorn ${DJANGO_WSGI_MODULE}:application \
  --name $NAME \
  --workers $NUM_WORKERS \
  --user=$USER \
  --group=$GROUP \
  --bind=127.0.0.1:8000 \
  --access-logfile /var/log/gunicorn/access.log \
  --error-logfile /var/log/gunicorn/error.log \
  --pid /var/tmp/gunicorn.pid \
  --log-level=info

我使用默认的wsgi.py和supervisord.conf文件。我的版本如下：

Django 1.8.4
Debian 8.2
Supervisor 3.0r1-1  (Installed globally)
Gunicorn 19.3.0     (Installed in virtual environment "hash1")

谁能看到我做错了什么？我不希望主管可以看到我的环境变量，这就是为什么我通过主管＆＃34;环境＆＃34;设置MEDIA_ROOT变量的原因。参数。但主管似乎仍然没有看到它。当我从命令行运行start-gunicorn脚本时，我能够启动gunicorn。我知道我做了一些愚蠢的事情，但我无法看到它。

谢谢！

我不确定，但我认为问题在于您在 root 用户环境中定义 MEDIA_ROOT ，然后以 smith <运行程序/ strong>用户，并且在其环境中未定义 MEDIA_ROOT 。也许您可以尝试编辑 base.py

def get_env_variable(var_name): try: return os.environ[var_name] except KeyError: error_msg = "Set the %s environment variable" % var_name # For debugging process append username and environment vars to error_msg user = os.environ['USER'] env_vars = os.environ.keys() error_msg += " current user: %s env_vars: %s" % (user, env_vars) raise ImproperlyConfigured(error_msg)

然后启动django并检查错误消息以检查用户是否在其环境中定义了 MEDIA_ROOT 。

无法通过主管启动Django / Gunicorn
