阿里云部署flask ，uwsgi restart fail

Question

要把自己的博客放到服务器上，代码是从github上pull下来的，一切就绪后，最后重启uwsgi，提示fail

(venv) root@iZ11anup6kpZ:/tmp# service nginx restart
 * Restarting nginx nginx                                                                                                                                                [ OK ] 
(venv) root@iZ11anup6kpZ:/tmp# service uwsgi restart
 * Restarting app server(s) uwsgi                                                                                                                                        [fail] 

看了下 uwsgi的log，显示如下

nginx配置文件如下

server {
    listen 80;
    server_tokens off;
    server_name zhaoyongbiao.me www.zhaoyongbiao.me;

     location / {
         include uwsgi_params;
         uwsgi_pass unix:/tmp/myblog.sock;
     }

     location /static {
         alias /var/www/myblog/app/static;
     }

     ## Only requests to our Host are allowed
     if ($host !~ ^(zhaoyongbiao.me|www.zhaoyongbiao.me)$ ) {
        return 444;
     }
}

uwsgi配置如下

[uwsgi]
vhost = true
socket = /tmp/myblog.sock
venv = /var/www/myblog/venv
chdir = /var/www/myblog
module = manage.py
callable = app

flask启动文件 manage.py

import os
from app import create_app, db
from app.models import User, Post, Tweet
from flask_script import Manager, Shell
from flask_migrate import Migrate, MigrateCommand

app = create_app(os.getenv('CONFIG') or 'default')
manager = Manager(app)
migrate = Migrate(app, db)


def make_shell_context():
    return dict(app=app, db=db, User=User, Post=Post, Tweet=Tweet)


@manager.command
def test():
    """Run the unit test"""
    import unittest
    tests = unittest.TestLoader().discover('tests')
    unittest.TextTestRunner(verbosity=2).run(tests)


manager.add_command('shell', Shell(make_context=make_shell_context))
manager.add_command('db', MigrateCommand)

if __name__ == '__main__':
    manager.run()

不知道到底是哪里出了问题（程序在本地是没问题的）

Answer 1

virtualenv配uwsgi，要填坑无数；建议改成Gunicorn（Flask官方推荐的!），保你一路顺风，延年益寿。说Gunicorn比uwsgi慢的主，都已经在填坑的过程中，顺便把自己埋了。

Answer 2

看一下uwsig的ini文件中app指向哪个模块
