nginx,tornado,websocket,supervisord配置成型

因为要上生产环境，所以配置还是专业一些比较好。

nginx.conf

upstream websocket_host {
    server 127.0.0.1:9527;
}

location /ws_log {
            proxy_redirect    off;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $host;
            proxy_pass http://websocket_host;
        }
        location /websocket {
            proxy_redirect    off;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $host;
            proxy_pass http://websocket_host;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
        }
