Question

我在OSX上使用MongoDB。我跟着一本书。

MongoDB: The Definitive Guide, Second Edition

我已安装并运行MongoDB。我已经制作了一些collections，其中包含一些values。

我使用Homebrew

安装

当我在终端中运行mongo时，我的shell启动了，我可以正常使用它。

当我运行mongod时，我收到一条错误消息，指出没有数据/ db目录。我知道这是因为mongo存储数据的默认位置在该目录中，但homebrew设置了自己的路径。

当我跑步时

Home:~ ThisIsMe$ mongo
MongoDB shell version: 2.6.3
connecting to: test
> db.serverCmdLineOpts()
{
    "argv" : [
        "/usr/local/opt/mongodb/bin/mongod",
        "--config",
        "/usr/local/etc/mongod.conf"
    ],
    "parsed" : {
        "config" : "/usr/local/etc/mongod.conf",
        "net" : {
            "bindIp" : "127.0.0.1"
        },
        "storage" : {
            "dbPath" : "/usr/local/var/mongodb"
        },
        "systemLog" : {
            "destination" : "file",
            "logAppend" : true,
            "path" : "/usr/local/var/log/mongodb/mongo.log"
        }
    },
    "ok" : 1
}
>

我得到homebrew设置我的mongo的文件路径。

我想确保一切设置正确。我是否需要添加其他内容才能正常运行mongod？我的印象是我应该能够运行mongod，然后转到http://localhost:28017/查看有关我的mongo的信息。

但我无法让mongod在没有data / db

错误的情况下运行

Answer 1

它出现在错误消息中：

ERROR: dbpath (/data/db) does not exist. 
Create this directory or give existing directory in --dbpath.

您需要创建/ data和/ data / db目录，并确保运行mongod的用户可以写入这两个目录。这就是mongod要编写数据库数据的地方。它不是默认创建的。或者，您可以在其他位置创建数据目录，然后使用--dbpath。

传递它

设置并运行MongoDB
