PyMySQL + WSGI / Flask nginx内部服务器错误

Question

我使用PyMysql安装了Flask

当我以开发模式python test.py运行它时，一切都很好，在浏览器中我能够在端口5000下看到SQL Select的结果

当我运行使用WSGI的Nginx service test start然后我得到内部服务器错误。我想它不是端口问题而是用户访问问题？我不知道为什么同一个文件在DEV中正常运行但在WSGI下运行不正常。或者可能是在nginx下它无法识别localhost？

app.py

from flask import Flask, request, render_template
import pymysql

db = pymysql.connect("localhost", "root", "123", "test1")

app = Flask(__name__)
#api = api(app)

@app.route('/')
def someName():
    cursor = db.cursor()
    sql = "SELECT name,password FROM Users"
    cursor.execute(sql)
    results = cursor.fetchone()
    return results[0] + str(results[1])
#    return render_template('index.html', results=results)

if __name__ == '__main__':
    app.run(host='0.0.0.0')
    app.debug = true

nginx配置

server {
   listen 80 default_server;

  # root /usr/share/nginx/html;
    root /var/www/html;
    index index.html index.htm;

   # Make site accessible from http://localhost/
   server_name mywebsite.com;

   location / { try_files $uri @rocket; }
      location @rocket {
      include uwsgi_params;
    uwsgi_pass unix:///var/www/rocket/myproject.sock;
   }

   location /images {
    alias /var/www/rocket/im;
    index index.html;
    }

   location /phpmyadmin {
      root /usr/share/;
      index index.php index.html index.htm;
