为django服务器设置gunicorn和supervisor

Question

我想让我的服务器启动并运行gunicorn和supervisor。 设法得到它UPP用这个命令：

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

这之后，我做了一个gunicorn_init.bash文件。我从几个教程中获得了代码。所以猜测这是设立监狱长和监督员的常用方法。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=- 

这只是给我的例外是这样的工作进程：

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

任何正确的方向指针现在非常赞赏。我被困了一段时间。

你有一个不一致的变量。在脚本的顶部，您定义了DJANGO_WSGI_MODULE，但在致电gunicorn时，您使用的是不存在的DJANGO_WSGI_UNICORN。确保你使用相同的名字。
