Apache 在 gcloud 500 内部服务器错误上运行 Flask答案

【问题标题】：Apache running Flask on gcloud 500 Internal Server ErrorApache 在 gcloud 500 内部服务器错误上运行 Flask
【发布时间】：2020-03-01 16:16:24
【问题描述】：

我一直在尝试将我的烧瓶应用程序部署在 apache 网络服务器上，并让它发挥了一定的作用。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 来处理与数据库相关的所有内容）或对一个已经令人兴奋的条目进行更改的唯一页面我收到 500 Internal Server Error。

读取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，但这并没有帮助。

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')

我在下面放置了最新的错误日志，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

【问题讨论】：

再次检查 SQLite 是否已安装且可用 ($sqlite3)。仔细检查 .prodigy 目录是否已在您的用户主目录中创建并且是可写的。
@ThaerA 非常感谢，现在开始工作了。
您能否将您的问题标记为已解决并为自己提供一个答案，以便其他人可以了解具体的操作？（可能跟随@Thaer A cmets，可能更多）
@RasmusBaj 很高兴它现在可以工作了。出了什么问题？
@ThaerA 我对包含 .db 文件的文件夹有权限问题，这就是整个问题

标签： python apache flask wsgi peewee

【解决方案1】：

由于文件夹权限问题而发生此问题。这已通过为包含 .db 文件的文件夹提供适当的权限来解决（在这种情况下，应用程序只有读取权限，这就是为什么仅在尝试更改或创建其中的内容时才会出现此问题）这些权限被读取和写。

所以在我的情况下，我使用 chmod 更改了我的 /var/www/FlaskApp/FlaskApp 文件夹（其中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
