Question

我试图通过nginx和gunicorn在VPS服务器上部署django项目，但是我得到了一个nginx错误＆＃39; 502坏网关＆＃39;当我尝试打开我的页面rollservice-rostov.ru

时

我的Nginx配置出了问题，但我无法弄清楚它是什么。

/etc/nginx/sites-enabled/rollservice.conf：

upstream rollservice-rostov.ru {
    server 127.0.0.1:8010 fail_timeout=0;
}

server {
    listen 80;
    server_name  www.rollservice-rostov.ru;
    rewrite ^/(.*) http://rollservice-rostov.ru/$1 permanent;
    client_max_body_size 4G;
    access_log /home/django/logs/rollservice/nginx.access.log;
    error_log /home/django/logs/rollservice/nginx.error.log;

    location /static/ {
        alias   /home/django/projects/rollservice/static/;
    }

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;

        if (!-f $request_filename) {
            proxy_pass http://rollservice-rostov.ru;
            break;
        }
    }

    error_page 500 502 503 504 /500.html;
    location = /500.html {
        root /home/django/projects/rollservice/templates/;
    }
}

/etc/supervisor/conf.d/rollservice.conf：

[program:rollservice]
command=/home/django/projects/rollservice/run/run.sh
directory=/home/django/projects/rollservice
user=django
autostart=true
autorestart=true
stderr_logfile=/home/django/logs/rollservice/gunicorn_errors.log
stdout_logfile=/home/django/logs/rollservice/gunicorn_access.log

/home/django/projects/rollservice/run/run.sh：

#!/bin/bash

NAME="rollservice"
SRCDIR=rollservice
HOMEDIR=/home/django

PROJECTDIR=${HOMEDIR}/projects/${NAME}
VIRTUALENV=${HOMEDIR}/.envs/${NAME}
SOCKFILE=${HOMEDIR}/tmp/${NAME}.sock

USER=django
GROUP=django
NUM_WORKERS=3
DJANGO_SETTINGS=rollservice.settings
DJANGO_WSGI_MODULE=rollservice.wsgi

echo "Starting $NAME as `whoami`"

# Activate the virtual environment
cd $PROJECTDIR
source ${VIRTUALENV}/bin/activate
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS
export PYTHONPATH=$PROJECTDIR:$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 ${VIRTUALENV}/bin/gunicorn ${DJANGO_WSGI_MODULE}:application \
  --name $NAME \
  --workers $NUM_WORKERS \
  --user=$USER --group=$GROUP \
  --bind=127.0.0.1:8010 \
  --log-level=debug \
  --log-file=$HOMEDIR/logs/

虽然，我的网页已成功通过

打开

lynx http://127.0.0.1:8010

这是最后一次错误记录：

Answer 1

我认为它的Django配置相关：如果您将DEBUG设置为False，则使用ALLOWED_HOSTS

允许任何域名

ALLOWED_HOSTS = ['*',]

仅允许您的域名

ALLOWED_HOSTS = ['rollservice-rostov.ru',]

配置文件settings.py可能会显示：

...
DEBUG = False
ALLOWED_HOSTS = ['rollservice-rostov.ru',]
...

要包含子域名，请添加＆＃34;。＆＃34;在开始

ALLOWED_HOSTS = ['.rollservice-rostov.ru',]

此外，在Django 1.7及更多

中

ALLOWED_HOSTS = [
   '.rollservice-rostov.ru',  # Allow domain and subdomains
   '.rollservice-rostov.ru.',  # Also allow FQDN and subdomains
]

检查Django文档 https://docs.djangoproject.com/en/dev/ref/settings/#allowed-hosts

Answer 2

由于上游命名，proxy_pass传递给FQDN时出现问题。

if (!-f $request_filename) {
    proxy_pass http://rollservice-rostov.ru;
    break;
}

它直接传递给那个。更改上游的名称，你应该没问题。
