[Python知识库]Flash uwsgi不执行if __name__ == ‘__main__‘里的内容

1、代码如下：

print(__name__)
if __name__ == '__main__':
    print('inner main')
    app.run()

2、使用 uwsgi启动，打印出来的是：uwsgi_file__opt_main，不会执行app.run

/usr/local/python3/bin/uwsgi uwsgi.ini

控制台显示：

WSGI app 0 (mountpoint='') ready in 2 seconds on interpreter 0x15ae5a0 pid: 9 (default app)
uWSGI running as root, you can use --uid/--gid/--chroot options
*** WARNING: you are running uWSGI as root !!! (use the --uid flag) *** 
*** uWSGI is running in multiple interpreter mode ***
spawned uWSGI worker 1 (pid: 9, cores: 2)
spawned uWSGI worker 2 (pid: 16, cores: 2)

3、使用python启动，打印出来的是：__main__以及inner main，执行了app.run,

python main.py

?执行到

cli.show_server_banner(self.env, self.debug, self.name, False)

控制台显示：

Serving Flask app "common" (lazy loading)
 * Environment: production
   WARNING: Do not use the development server in a production environment.
   Use a production WSGI server instead.
 * Debug mode: off
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

4、如果将'__main__'改为：'uwsgi_file__opt_main'，并使用uwsgi方式启动

在linux控制台下，可以看到有两个端口占用，一个是uwsgi的，一个是app.run的默认5000端口

telnet localhost 8090
telnet localhost 5000
ctrl + ]

5、所以，需要初始化的代码，用uwsgi启动时，不要放在if __name__ = '__main__':下?
