为 django 服务器设置 gunicorn 和 supervisor

Question

我正在尝试使用 gunicorn 和主管启动并运行我的服务器。 设法用这个命令把它升级：

$ gunicorn project.wsgi:application --bind 192.168.1.130:8000

之后我制作了一个 gunicorn_init.bash 文件。我从几个教程中获得了代码。所以猜猜这​​是设置 gunicorn 和 supervisor 的常用方法。代码如下所示：

#!/bin/bash

NAME="project"                                                   # Name of the application
DJANGODIR=/home/username/projects/project                    # Django project directory
SOCKFILE=/home/username/.venvs/project/run/gunicorn.sock     # We will communicate using this unix socket
USER=username                                              # the user to run as
GROUP=username                                             # the group to run as
NUM_WORKERS=1                                                   # how many worker processes shoul Gunicorn spawn
DJANGO_SETTINGS_MODULE=project.settings.production               # which settings file should Django use
DJANGO_WSGI_MODULE=project.wsgi                                  # WSGI module name
echo "Starting $NAME as `whoami`"

# Activate the virtual environment

cd $DJANGODIR
source /home/username/.venvs/project/bin/activate
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DJANGODIR:$PYTHONPATH

# Create the run directory if it doesn't exsist

RUNDIR=$(dirname $SOCKFILE)
test -d $RUNDIR || mkdir -p $RUNDIR

# Start yout Django Unicorn
# Programs meant to be run under supervisor should not daemonize themselves (do not use daemon)

exec gunicorn ${DJANGO_WSGI_UNICORN}:application \
  --name $NAME \
  --workers $NUM_WORKERS \
  --user=$USER --group=$GROUP \
  --bind=unix:$SOCKFILE \
  --log-level=debug \
  --log-file=-

这只是给我一个例外是这样的工作进程：

我阅读并观看了教程。进入文档，试图弄清楚为什么在调用 gunicorn-bash 文件时它不起作用。

现在非常感谢任何指向正确方向的指针。我已经卡了很长时间了。

您有一个不一致的变量。在脚本顶部定义DJANGO_WSGI_MODULE，但在调用gunicorn 时，您使用的是不存在的DJANGO_WSGI_UNICORN。确保使用相同的名称。
