【问题描述】：

我通过 Homebrew 安装了 MongoDB，并创建了 /data/db 目录。

当我运行sudo chown -R id -un /data/db 时。我收到此错误：

chown: data/db: 没有那个文件或目录

我已经尝试了所有可以在网上找到的解决方案，我发现该目录存在，但我不确定发生了什么。当我运行 mongod 这就是我得到的结果：

【问题讨论】：

究竟是什么问题？意思是/data/db 不是文件。而且我认为在大多数 GNU/Linux 发行版中，/data 不是标准目录。请澄清您的问题并告诉我们您想要达到的目标。

【解决方案1】：

在您的 Mac 上，如果您使用 Homebrew 安装 MongoDB，则会在安装时创建数据目录。但是，它不是data/db。相反，在 Intel Mac 上是 /usr/local/var/mongodb，在 M1 Mac 上是 /opt/homebrew/var/mongodb。

要使用 Homebrew 正确安装 MongoDB（当然，请检查最新版本）：

 brew tap mongodb/brew
 brew install mongodb-community@5.0

首先，通过使用brew 列出正在运行的服务来检查您的 MongoDB 是否运行正常：

brew services list

您应该会看到如下内容：

Name              Status  User File
MongoDB-community started root

如果没有，尝试停止、启动或重启服务：

 brew services stop mongodb/brew/mongodb-community
 brew services start mongodb/brew/mongodb-community
 brew services restart mongodb/brew/mongodb-community

有关可能出现的问题的更多信息，请查看日志文件：

 tail $(brew --prefix)/var/log/mongodb/mongo.log

更多详情请关注official documentation。
