Question

您好我正在尝试使用Flask在我通过ssh访问的Ubuntu 13.1服务器上设置一个restful api。我以为我已经正确设置了nginx和uwsgi，但是当我在浏览器中导航到我的IP地址（xxx.xxx.x.xxx）时，我得到以下消息而不是经典的nginx欢迎页面：

＆＃34;发生错误。抱歉，您要查找的页面目前无法使用。请稍后再试。如果您是此资源的系统管理员，则应检查错误日志以获取详细信息。＆＃34;

当我在这里查看nginx错误日志时，我看到了：

2014/03/22 08:51:12 [crit] 23903#0: *1 connect() to unix:/tmp/uwsgi.sock failed (2: No such file or directory) while connecting to upstream, client: xxx.xxx.x.2xx, server: localhost, request: "GET /favicon.ico HTTP/1.1", upstream: "uwsgi://unix:/tmp/uwsgi.sock:", host: "xxx.xxx.x.1xx"

我遵循的教程是：http://conra.dk/2012/05/06/flask-uwsgi-nginx-ubuntu.html

以下是我的文件：

/etc/apt/sources.list.d/nginx-lucid.list：

deb http://nginx.org/packages/ubuntu/ lucid nginx
deb-src http://nginx.org/packages/ubuntu/ lucid nginx

/etc/init/uwsgi.conf

description "uWSGI"
start on runlevel [2345]
stop on runlevel[06]

respawn

exec uwsgi --master --processes 4 --die-on-term --uid uwsgi --gid nginx --socket /tmp/uwsgi.sock --chmod-socket 660 --no-site --vhost --logto /var/log/uwsgi.log

/etc/logrotate.d/uwsgi

/var/log/uwsgi.log {
    rotate 10
    daily
    compress
    missingok
    create 640 uwsgi adm
    postrotate
        initctl restart uwsgi >/dev/null 2>&1
    endscript
}

/etc/nginx/conf.d/helloworld.conf

server {
    listen       80;
    server_name  localhost;

    location /static {
        alias /srv/www/helloworld/static;
    }

    location / {
        include uwsgi_params;
        uwsgi_pass unix:/tmp/uwsgi.sock;
        uwsgi_param UWSGI_PYHOME /srv/www/helloworld/env;
        uwsgi_param UWSGI_CHDIR /srv/www/helloworld;
        uwsgi_param UWSGI_MODULE application;
        uwsgi_param UWSGI_CALLABLE app;
    }

    error_page   404              /404.html;

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

所以当我使用：

重新启动uwsgi时

sudo service uwsgi restart

我收到此消息：

stop: Unknown instance: 
uwsgi start/running, process 23969

然后当我尝试运行时

uwsgi --http 127.0.0.1:9090 --pyhome ./env --module application --callable app

我收到此消息：
