我尝试重新启动生产中的项目，但它停止工作了。这是一个 django==1.5.1 和 django-cms==2.4.1 项目。我重新启动是因为我已将项目从 django==1.4.1 更新为 django==1.5.1，但我知道这不会改变 wsgi.ini 中的任何内容。
当我第一次重新加载项目时，它引发了 500 错误。然后我决定删除我的 /tmp/zecaffe.sock 来重新创建它，然后我再次重新启动该项目，现在当我查看我的 error_zecaffe.log 时，它显示了此错误：
2013/05/03 16:16:35 [crit] 32378#0: *207 connect() to unix:///tmp/zecaffe.sock failed (2: No such file or directory) while connecting to upstream, client: 189.75.17.67, server: zecaffe.infalms.com.br, request: "GET / HTTP/1.1", upstream: "uwsgi://unix:///tmp/zecaffe.sock:", host: "zecaffe.infalms.com.br"

看来 Emperor 没有重新创建另一个 .sock 文件。好吧，这是我的 uwsgi.ini：
[uwsgi]
# caminho para o virtualenv no qual o projeto ira rodar
home = /home/infalms/.virtualenvs/zecaffe
# socket gerado no momento da inicializacao do uwsgi. Pode ser um servidor ou arquivo.sock.

您需要检查在目录中创建 .sock 文件的权限/tmp/。我建议为 .pid 和 .sock 文件创建不同的目录：
cd /var/run/
makedir django
chown www-data:www-data django
然后将设置更改为：
socket=/var/run/zecaffe.sock
或者使用 gunicorn（推荐）：
workon zecaffe
pip install gunicorn
gucicorn.conf.py在目录中创建运行应用程序的文件/var/www/zecaffe/conf：
#! coding: utf-8
import os
import multiprocessing
os.environ['DJANGO_SETTINGS_MODULE'] = 'zecaffe.settings'
short_name = "zecaffe"
bind = "unix:/var/run/django/%s.sock" % short_name
proc_name = "/var/run/django/%s" % short_name
workers = multiprocessing.cpu_count() * 2 + 1
user = "www-data"
group = "www-data"
loglevel = "warn"
timeout = 600
keepalive = 5
安装 Supervisor 并将其添加到 /etc/supervisor/conf.d/zecaffe.conf：
[program:zecaffe]
directory = /var/www/zecaffe
user="www-data"
group="www-data"
environment=DJANGO_SETTINGS_MODULE="zecaffe.settings",PYTHONIOENCODING="UTF-8",LANG="en_US.UTF-8",LC_ALL="en_US.UTF-8",LC_LANG="en_US.UTF-8"
command=/var/www/.virtualenvs/zencafe/bin/gunicorn_django -c /var/www/zecaffe/conf/gunicorn.conf.py
stderr_logfile = /var/www/zecaffe/log/supervisor_error.log
不要忘记改变模式gunicorn.conf.py：
chmod u+x /var/www/zecaffe/conf/gunicorn.conf.py
奔跑supervisorctl update并享受吧！

我遇到了同样的错误。
settings.py 中缺少必需的设置：
# Hosts/domain names that are valid for this site; required if DEBUG is False
ALLOWED_HOSTS = ['.my-domain.com']
看https://docs.djangoproject.com/en/1.5/ref/settings/#allowed-hosts
