【问题描述】：

我正在 Elastic Bean Stalk 上构建一个烧瓶应用程序。部署后我收到 500 内部服务器错误。当我查看日志时，发现有错误。

Traceback (most recent call last):
File "/opt/python/current/app/application.py", line 32, in <module>
application.run(debug=True, port=server_port, host='0.0.0.0')
File "/opt/python/run/venv/lib/python2.7/site-packages/flask/app.py", line 739, in run
run_simple(host, port, self, **options)

test_socket.bind((hostname, port))

mod_wsgi (pid=6577): Target WSGI script '/opt/python/current/app/application.py' cannot be loaded as Python module.
mod_wsgi (pid=6577): Exception occurred processing WSGI script '/opt/python/current/app/application.py'.

application.py文件如下

from flask import Flask

application = Flask(__name__)

application.debug = True

# Application routes defined here
@application.route('/index')
def index():
    return "Hello World!"


# Run the application
application.run(debug=True, host='0.0.0.0')

我尝试了很多。我不明白发生了什么。在阅读了其他***问题后，我发现这是由于没有root权限引起的。我将如何在弹性豆茎中以 root 权限运行我的 WSGI 脚本。

【参考方案1】：

用途：

# Run the application
if __name__ == '__main__':
    application.run(debug=True, host='0.0.0.0')

在 mod_wsgi 下运行时不应执行 application.run() 调用。仅在从命令行运行该脚本时才适用。 'if' 语句将确保它不会在 mod_wsgi 下被调用。
