Python 502访问服务器时网关nginx错误

我正在使用nginx+uwsgi+python创建一个简单的“helloworld应用程序”。然而，当我尝试使用我的服务器ip访问时，浏览器中出现坏网关错误

nginx错误日志显示：

2016/12/25 17:23:21 [crit] 10269#10269: *1 connect() to unix:///home/manish/pyapp/pyapp.sock failed (2: No such file or directory) while connecting to upstream, client: 122.161.59.236, server: 35.154.95.139, request: "GET / HTTP/1.1", upstream: "uwsgi://unix:///home/manish/pyapp/pyapp.sock:", host: "35.154.95.139"

以下是我配置的一些文件：

pyapp.ini文件

[uwsgi]
module = wsgi:application

http-socket = :8080

master = true
processes = 5

socket = pyapp.sock
chmod-socket = 660
vacuum = true

die-on-term = true

pyapp/wsgi.py文件

def application(environ, start_response):
    start_response('200 OK', [('Content-Type', 'text/html')])
    return ["<h1 style='color:blue'>Hello There!</h1>"]

nginx文件

sudo nano/etc/nginx/sites available/pyapp

server {
    listen 80;
    server_name 35.154.95.139;

    location / {
        include         uwsgi_params;
        uwsgi_pass      unix:/home/manish/pyapp/pyapp.sock;
    }
}

非常感谢您的帮助。

此问题与缺少upstart库有关。安装upstart文件后，它工作了。

也许这个问题很愚蠢，但是。。您是否已使用此套接字启用uwsgi？通过安装upstart library解决了此问题
