MongoDB社区：无法在任何兼容版本下启动WiredTiger

Question

今天，我没有做任何明显的更改，我的mongodb-community停止工作了。 当我检查了brew服务时，我发现错误状态。

mongodb-community error  3584 user ~/Library/LaunchAgents/[e-mail]

我检查了日志，发现了这个错误：

我在谷歌和Stack中搜索并找到了一些解决方案，例如将MongoDB降级至版本4.2.x或设置权限，但这些都没有起作用。

我应该怎么办？即使这是一个带有虚拟数据的本地服务器，我也可以考虑丢失数据。无论如何，我想以正确的方式解决它。

谢谢。

似乎您需要修复数据文件夹权限：“Reason: 13: Permission denied”，可以尝试使用类似 chown -R mongo /data/ 的命令来解决。 - R2D2

Answer 1

这通常发生在升级时，请检查您的mongo版本。我在几台服务器上也遇到了同样的问题。避免这种情况的正确方法是在进行mongo升级之前将FCV（featureCompatibilityVersion）设置为正确的版本。在这种情况下，应将其设置为版本4.2，然后再进行升级到mongo 4.4。要检查当前的FCV，请在mongo shell（admin db）中运行以下命令：

db.adminCommand({ getParameter: 1, featureCompatibilityVersion: 1 })

在我的情况下，版本号是4.0，所以我需要执行更新操作：

db.adminCommand( { setFeatureCompatibilityVersion: "4.2" } )

然后升级到Mongo 4.4很顺利。

如果您已经搞砸了，应该可以降级到Mongo 4.2.6或更高版本，按照上述方法更新FCV，然后再升级到Mongo 4.4。根据您的日志，看起来它没有访问某些文件（例如/var/lib/mongodb/）的权限，因此请确保这些文件归mongodb用户所有。

Answer 2

我使用以下命令安装了非官方的mongoDB：

sudo apt-get install mongodb

然后我卸载了它，但是使用remove而不是purge

然后根据官方网页安装了mongodb-org，得到相同的错误Failed to start up WiredTiger under any compatibility version.

之后，我使用purge卸载了与mongodb有关的一切，重新安装了mongdb，再次使用purge卸载它，然后重新安装了mongodb-org。

问题已解决。

@chovy，你能详细描述一下你的问题吗？ - Draculea

我刚刚删除了所有的数据库文件并进行了升级。这个过程很顺利。 - chovy
