我一直在尝试使用apache作为服务器（wsgi_mod）来部署我的flask应用程序。我创建了所有必需的文件（Apache的.wsgi和.conf文件）。
但是当我请求页面时，出现500错误。查看日志显示

我正在尝试将此应用程序部署在debian 9服务器中。我已经在我的kali盒子上对其进行了测试，仅通过安装flask和paramiko并配置apache即可正常工作。
我尝试重新安装一些软件包，例如paramiko，flask和Werkzeug，但没有成功。
我什至创建了一个带有简单的hello world消息的新应用。直到我导入paramiko，然后出现“权限被拒绝”错误，它才能正常工作。
我的测试应用包含三个文件。
from flask import Flask
import paramiko
app = Flask(__name__)
@app.route("/")
def hello():
return "Hello world!"
if __name__ == "__main__":
app.run()
import logging
import sys
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0, '/var/www/html/ExampleFlask/ExampleFlask/')
from my_flask_app import app as application
application.secret_key = 'thisisasecretkey'

apache用户没有从该目录读取所需的权限。我们仅使用以下命令为另一组添加读取权限：
