由于 WiredTiger.turtle 权限，Mongodb 无法启动

Question

我正在尝试在 ubuntu 16.04 上启动 mongodb 4.0.4，但数据库拒绝了我的所有尝试。我检查了 mongodb 日志文件，发现名为 WiredTiger.turtle 的文件没有所需的权限。这里记录错误:

我为/var/lib/mongodb/中的所有文件授予了所有权限。但是当我启动 mongodb WiredTiger.turtle 文件的权限时。只是为了检查我删除了这个文件，但文件再次出现并且错误重复。

Answer 1

与 WiredTiger.turtle 权限相同的问题。 Ubuntu 18.04
我的问题是我用 sudo 启动了一个 mongod 服务。这在我的数据库目录中创建了具有 root:root 所有权的文件。在没有 sudo 的情况下启动 mongod 服务时，我收到了权限被拒绝的错误。
解决方案是将 db 目录中所有文件的所有权改回 mongodb:mongodb
$ sudo chown -R mongodb:mongodb /var/lib/mongodb/*
