此外，在获取502坏网关错误时，我在nginx_error.log文件中也看到了这一点：

2015/07/16 14:10:18 [error] 28289#0: *1 upstream prematurely closed connection while reading response header from upstream, client: 127.0.0.1, server: 127.0.0.1, request: "GET /myapplication/ HTTP/1.1", upstream: "uwsgi://127.0.0.1:27070", host: "myserver_name.com", referrer: "http://myserver_name.com/"

尝试在setting.py中将localhost或您的ip/domain添加到允许的\u主机，如下所示

允许的_HOSTS=['localhost'，'127.0.0.1'，'your.server.ip.here']

同时删除以下内容：

听127.0.0.1:27070

uwsgi_通行证127.0.0.1:27070

代用通行证

并使nginx使用unix套接字代替ini文件中的套接字

socket=/tmp/sockets/myapplication.sock

几天来，我一直面临着完全相同的问题……我知道这是一个旧线程，但你还记得如何修复它吗？
