我想将flask应用程序部署到ubuntu apache2服务器。我做了什么：
1。创建了git存储库并将烧瓶文件上传到git，但 venv文件夹除外（因为那里有.bat，.exe文件）。
2。打开的Ubuntu VPS服务器安装了git，apache2，apache2-dev，python3.7，python3.7-dev，libapache2-mod-wsgi-py3，python-virtualenv。
3。克隆项目并cd project_name/进入该项目，而不是创建虚拟环境python -m venv venv。
4。激活了虚拟环境并安装了烧瓶，firebase-admin pip install flask firebase-admin。
5。 Flask应用程序文件 madad_admin.py （我的项目内容的主文件）：
import os, firebase_admin
from flask import Flask, render_template, request, jsonify, url_for
from firebase_admin import credentials, firestore
app = Flask(__name__)
cred = credentials.Certificate('./GenerateAdminSDKKey.json')
firebase_admin.initialize_app(cred)
db = firestore.client()
@app.route('/')
def index():
users_ref = db.collection('users')
docs = users_ref.get()
for doc in docs:
print('{}'.format(doc.to_dict()))
return render_template('index.html')
if __name__ == "__main__":
app.run(debug=True)
6。创建了 madad_admin.wsgi 文件竞争：
#! /usr/bin/python3.7
import sys
sys.path.append('/workspace/sites/madad_admin/venv/lib/python3.7/site-packages')
sys.path.insert(0, "/workspace/sites/madad_admin")
from madad_admin import app as application
7。在 / etc / apache2 / site-available 文件夹名称为 madad.conf 的目录中创建的apache2配置文件：
<VirtualHost *:80>
WSGIDaemonProcess madad_admin user=www-data group=www-data threads=5
WSGIScriptAlias / /workspace/sites/madad_admin/madad_admin.wsgi
DocumentRoot /workspace/sites/madad_admin
<Directory /workspace/sites/madad_admin>
WSGIProcessGroup madad_admin
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
启用了
a2ensite madad.conf 禁用默认的一个。
问题是，如果我在浏览器中打开应用程序，则会显示内部服务器错误500 ，并且日志文件显示以下内容：

但所有软件包已安装在虚拟环境中。
比在运行时使用python madad_admin.py命令 的所有操作 wsgi中的某些错误。谢谢！
