我在 init.py 中的连接字符串是

Base.metadata.bind = engine
DBSession = sessionmaker(bind=engine)
session = DBSession()
db = SQLAlchemy(app)

我在 /var/www/ 中的文件层次结构是

FlaskApp flaskapp.wsgi FlaskApp 静态模板 venv 初始化.py database_setup IT_DataBase.db

这是flaskapp.wsgi中的配置

#!/usr/bin/python                                                                
activate_this = '/var/www/FlaskApp/FlaskApp/venv/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))

import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/FlaskApp/")

from FlaskApp import app as application
application.secret_key = 'super_secret_key!'

这是 apache 的 FlaskApp.conf

<VirtualHost *:80>
        ServerName mywebsite.com
        ServerAdmin admin@mywebsite.com
        WSGIScriptAlias / /var/www/FlaskApp/flaskapp.wsgi

（编辑）我当我尝试运行 python flaskapp.wsgi 它给出了同样的错误

【问题讨论】：

这里的一些答案似乎值得检查：***.com/questions/7670289/… 尝试了解决方案并将所有者更改为 www-data 并授予 .db 文件 777 权限，但同样的问题哦，这不是一个合适的解决方案，允许系统中的每个人读取和写入您的数据库并不是最佳的，至少从长远来看是这样。我知道，我只是想让它在 apache 上工作，现在租用 【参考方案1】：

通过授予 www-data 所有权并从数据库设置中删除几行来解决问题

【讨论】：

以上是关于apache flask sqlite 无法在 ubuntu 上打开数据库文件的主要内容，如果未能解决你的问题，请参考以下文章
