更新:如果我不使用套接字，而是使用127.0.0.1:3031，则一切正常。
Nginx版本是1.6.3，而uwsgi是2.0.11.1
/etc/uwsgi.ini:
[uwsgi]
uid = uwsgi
gid = uwsgi
pidfile = /run/uwsgi/uwsgi.pid
emperor = /etc/uwsgi.d
stats = /run/uwsgi/stats.sock
emperor-tyrant = true
cap = setgid,setuid
logto = /var/log/uwsgi.log
/etc/uwsgi.d/daimaduan_preview.ini
[uwsgi]
plugin = python,http
protocol = uwsgi
chdir = /var/www/daimaduan/preview/current
master = true
processes = 4
threads = 20
socket = /tmp/daimaduan-preview.sock
chmod-socket = 666
uid = vagrant
gid = vagrant
logto = /var/log/daimaduan/preview/uwsgi.log
virtualenv = /var/www/daimaduan/preview/venv
wsgi-file = deploy.wsgi
/etc/nginx/conf.d/daimaduan.conf
server {
listen 80;
server_name example.com;
access_log /var/log/daimaduan/preview/access.log;
error_log /var/log/daimaduan/preview/error.log;
root /var/www/daimaduan/preview/current/daimaduan;
location / {
uwsgi_pass unix:/tmp/daimaduan-preview.sock;
include uwsgi_params;
}
}
但是，我通过访问http://127.0.0.1/从nginx得到了错误:

而且我很确定
/tmp/daimaduan-preview.sock确实存在。我还检查了uwsgi日志:*** Starting uWSGI 2.0.11.1 (64bit) on [Tue Oct 6 15:38:09 2015] ***

它看起来也很正常。
这里有一些问题:
/etc/uwsgi.d/daimaduan.ini中不生效？ /tmp/daimaduan-preview.sock的所有权？我尝试了chown-socket但失败了No such file or directory中出现/var/log/daimaduan/preview/uwsgi.log错误？ 最佳答案
将daimaduan_preview.ini的套接字文件放入/run而不是/tmp。像this答案中一样，您的系统可能使用命名空间临时目录，这意味着每个服务只能在/tmp中看到其自己的文件。
