django - 502 Bad Gateway - django + nginx + gunicorn - socks 失败(13 : Permission denied)

Question

我正在关注本教程:https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-14-04

我相信我的设置中的其他一切都是正确的。文件/var/log/nginx/error.log 有许多以下错误:

2015/12/19 18:41:58 [crit] 10850#0: *23 connect() to unix:/home/root/myproject/myproject.sock 失败 (13: 权限被拒绝) 连接上游时，客户端:[[my ip]]，服务器:[[server ip]]，请求:“GET/HTTP/1.1”，上游:“http://unix:/home/root/myproject/myproject.sock:/”，主机:“[[server ip]] ”

命令:

/home/root/myproject ls -l /home/root/classNote/classNote.sock

输出:

srwxrwxrwx 1 root www-data 0 Dec 19 18:17 /home/root/myproject/myproject.sock

编辑:安德烈的评论回应:

命令:

ps ax | grep gunicorn

输出:

Answer 1

似乎存在权限问题以 root 身份启动您的 nginx 服务，因为 root 有权访问您的 my project.sock

sudo service nginx stop

然后

 sudo service nginx start

但是以root身份启动nginx并不是一个好主意。您可以尝试更改当前用户的权限

我可以建议你一个工作正常的替代方案。
让一个 shell 脚本来处理这一切。
像这样创建一个shell脚本(*表示在注释中是必需的)

#!/bin/bash

NAME=""                              #Name of the application (*)
DJANGODIR=/path/to/django/project            # Django project directory (*)
SOCKFILE=/path/to/socket/file/myproject.sock        # we will communicate using this unix socket (*)
USER=                                      # the user to run as (*)
GROUP=                                     # the group to run as (*)
NUM_WORKERS=1                                     # how many worker   processes should Gunicorn spawn (*)
DJANGO_SETTINGS_MODULE=yourproject.settings             # which settings file should Django use (*)
DJANGO_WSGI_MODULE=yourproject.wsgi                     # WSGI module name (*)

echo "Starting $NAME as `whoami`"

# Activate the virtual environment
cd $DJANGODIR
source /path/to/virtualenv/bin/activate
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DJANGODIR:$PYTHONPATH

# Create the run directory if it doesn't exist
RUNDIR=$(dirname $SOCKFILE)
test -d $RUNDIR || mkdir -p $RUNDIR

# Start your Django Unicorn
# Programs meant to be run under supervisor should not daemonize themselves (do not use --daemon)
exec /path/to/virtualenv/bin/gunicorn ${DJANGO_WSGI_MODULE}:application \
  --name $NAME \
  --workers $NUM_WORKERS \
  --user $USER \
  --bind=unix:$SOCKFILE
