所以我已经在我的macbook上成功安装了mongodb。当我运行'brew install mongodb'命令行时，我说这个bc说：'mongodb-2.6.7已安装。我运行了命令'mkdir -p / data / db'，虽然我无法真正遵循它做的事情（我已经尝试通过SO和Mongo网站上的其他一些线程，但不明白如何解决问题; sry我有点蠢蠢欲动，并不真正理解这个问题）。但是，当我输入mongod以查看它是否成功运行时，我得到以下错误/输出

列出的一个问题是“软限制太低”，但我的理解是因为我只是为了开发而不是生产目的这样做而无关紧要。有人可以提供如何解决此错误？这是一个类似的线程，但我不知道该怎么做：
Trouble installing mongodb using Homebrew
运行sudo chown $ USER / data / db之后我现在得到：

这是否意味着它现在正在运作？
答案 0 :(得分：0)
是的，这是有效的。当您运行“mongod”并看到此“waiting for connections on port 27017”时，您的mongodb运行良好，您可以开始查询它。
