升级到 Mac BIgSur 后 Mongo 启动问题 - 无法取消链接套接字文件

如何解决升级到 Mac BIgSur 后 Mongo 启动问题 - 无法取消链接套接字文件

我已将 MacO 升级到 BigSur。从那以后我就无法启动我已经安装的 Mongo。

所以，我决定卸载我的 4.2 Mongo 版本并转到 4.4 版本：

$ brew uninstall mongodb
$ brew install mongodb-community@4.4

一切正常。

运行时我必须升级到 XCode 12（使用 AppStore 应用程序完成）。

一切正常。

现在是启动 Mongo 的时候了：

$ brew services start mongodb-community@4.4

我收到以下错误：

似乎是“无法取消链接套接字文件”是问题所在。我怀疑这与 BigSur 安全功能有关，但我不知道如何解决。试图在系统偏好设置中查看和“安全偏好设置”，但我找不到 Mongo 问题。

解决方法

这是一个权限问题。

错误消息中指出的套接字文件归root所有，其他用户没有权限。日志里特别标注了权限被拒绝，说明brew用来启动服务的账号不是root。

"msg":"Failed to unlink socket file","attr":{"path":"/tmp/mongodb-27017.sock","error":"Permission denied"}

要解决此问题，请使用 sudo rm /tmp/mongodb-27017.sock 手动删除文件，然后尝试启动 mongod。
