为什么我的Ubuntu Apache服务器上的Flask应用程序被拒绝了？

环境：

Python 3.7.5

烧瓶1.1.2

托管公司：Ionos

类型：带有Plesk面板的ubuntu上的VPS。

Ubuntu 18.04.5 LTS，代号：仿生

我有一个网站域名。通用域名格式。例如，我需要子域“dashboard.domain.com”上的仪表板。我的服务器是一个虚拟服务器，使用“虚拟主机”和apache作为我在这个VPS上的所有域名。我正试图在带有子域的ubuntu服务器上部署我的python flask应用程序。我在服务器上安装了必要的软件包（wsgi、flask等）

之后，我做了以下工作：

域的文件。com位于：

/var/www/vhosts/domain.com/httpdocs/

我在域中创建了一个文件夹“dashboard”。com文件夹：

/var/www/vhosts/domain.com/dashboard

在此文件夹中，我上传了Flask应用程序的所有文件：

dashboard/
  - forms.py
  -__init__.py
  -models.py
  -myproj
  -routes.py
  -static/
  -templates/
  
dashboard.wgsi
favicon.ico

我创建了仪表板。wgsi文件：

#!/usr/bin/python导入系统导入日志系统。标准输出=系统。stderr日志记录。基本配置（流=系统标准）系统。路径插入（0，“/var/www/vhosts/domain.com/dashboard/”）

从仪表板导入应用程序作为应用程序。密钥='Paris@TOTO'

和初始化。py文件：

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_login import LoginManager
import os

app = Flask(__name__)
print(app)
SECRET_KEY = os.urandom(32)
app.config['SECRET_KEY'] = SECRET_KEY
app._static_folder = os.path.abspath("dashboard/static")
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://dashboard:toto@toto@218.218.88.98/db_alejo'

db_mysql = SQLAlchemy(app)
login_manager = LoginManager(app)
login_manager.login_view='login'
login_manager.login_message_category='info'
import routes



if __name__ == "__main__":
    app.run(host='0.0.0.0',threaded=True,port=80, debug=True)

我在/etc/apache2/sites-available中创建了conf文件“dashboard.conf”/

 ServerAdmin admin@domain.com

 RewriteEngine On

 RewriteCond %{HTTP_HOST} !^www\. [NC]

 RewriteRule ^(.*)$ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

 ServerName dashboard.domain.com

 Redirect "/" "https://dashboard.domain.com/"

 WSGISocketPrefix run/wsgi

 DocumentRoot /var/www/vhosts/domain.com/dashboard

 WSGIScriptAlias / /var/www/vhosts/domain.com/dashboard/dashboard.wsgi

 </Directory>
 ErrorLog ${APACHE_LOG_DIR}/error-dashboard.log
 LogLevel warn

我在 /etc/apache2/中启用这个新的虚拟主机：

sudo a2ensite仪表板

我重新启动了Apache：

sudo服务apache2重启

然后，当我测试url的仪表板时。领域com“在我的浏览器中，我得到ERR\u CONNECTION\u拒绝错误。

所以我去检查/var/log/apache2中的错误日志文件

access-dashboard.log
access.log
error-dashboard.log
error.log
etc...

通道日志，访问仪表板。日志和错误仪表板。日志为空！

但是错误。日志显示：

这表明Apache的SSL设置存在错误，根据本文的说法，这是一个很容易解决的问题

您应该将服务器重命名为localhost，例如：

ServerName localhost

我想补充一点，我无法重现你的错误，我得到的只是警告，但我的应用程序似乎运行良好。我给出这个答案的目的不仅是为了帮助，而且是为了验证这个问题可以通过这种方式解决。

请回来告诉我们进展如何））

您有一个重定向到https:/。。。但您不会显示虚拟主机在端口443上侦听：

Redirect "/" "https://dashboard.domain.com/"
