Apache 运行 gcloud 上的 Flask 500 内部服务器错误
Apache running Flask on gcloud 500 Internal Server Error
我一直在尝试将我的 flask 应用程序部署到 apache 网络服务器上，并使其能够正常运行。
我现在面临的问题是，我需要在我的数据库中创建一个新条目（使用 peewee sqlite 处理与数据库相关的所有内容）或更改已经令人兴奋的条目的唯一页面我收到 500 内部服务器错误。
读数据库时似乎功能齐全，但无法写入。我已将 .db 文件权限更新为 777，但这没有帮助。
以下代码在 Flask 文件中并声明了 .db 文件的路径：
APP_DIR = os.path.dirname(os.path.realpath(__file__))
# Specifying the path of the DB file
DATABASE = 'sqliteext:///%s' % os.path.join(APP_DIR, 'blog.db')
我已将最新的错误日志放在下面，它是在尝试创建新条目时发生的，非常感谢任何想法。

编辑：通过评论解决
此问题是由于文件夹权限问题造成的。
这是通过为包含 .db 文件的文件夹提供适当的权限来解决的（在这种情况下，应用程序只有读取权限，这就是为什么这个问题只在尝试更改或创建其中的内容时发生）这些权限被读取和写.
所以在我的例子中，我使用 chmod 更改了我的 /var/www/FlaskApp/FlaskApp 文件夹（包含我所有的烧瓶文件和我的 .db 文件）的权限，这解决了问题

编辑：通过评论解决
此问题是由于文件夹权限问题造成的。 这是通过为包含 .db 文件的文件夹提供适当的权限来解决的（在这种情况下，应用程序只有读取权限，这就是为什么这个问题只在尝试更改或创建其中的内容时发生）这些权限被读取和写.
所以在我的例子中，我使用 chmod 更改了我的 /var/www/FlaskApp/FlaskApp 文件夹（包含我所有的烧瓶文件和我的 .db 文件）的权限，这解决了问题
