如何设置mongod --dbpath

一般来说,mongodb和数据库都是新手.每当我运行时,mongo我收到此错误消息:

MongoDB shell version: 2.4.9
connecting to: test
Thu Jan 30 13:03:33.170 Error: couldn't connect to server 127.0.0.1:27017 
at src/mongo/shell/mongo.js:145
exception: connect failed

运行mongod我看到这一点:

当我手动设置我的mongo dpath mongod --dbpath /data/db(因为应该是安装时的默认值)并保持它在终端运行一切正常.但是一旦我关闭它,一切都会再次破裂.我的问题是:

为什么我的dbpath设置为/usr/local/var/mongodb？

我如何修复此错误,以便mongo在我的机器上工作？

我假设我需要永久设置dbpath /data/db或重新配置一些东西,所以它适用于dbpath/usr/local/var/mongodb

我也是unix命令的新手,所以不完全确定如何修复此错误.

谢谢你的任何建议!

所以,通过mongodb文档挖掘我读到这个:

"除非另有说明,否则mongod将在默认/data/db目录中查找数据文件.(Windows系统使用\ data\db目录.)如果使用软件包管理系统安装.请检查/etc/mongodb.conf软件包提供的文件以查看软件包的配置dbpath. "

当我看看里面的文件/etc/没有mongodb.conf文件...但是,我确实看到/usr/local/etc/mongod.conf...所以,如果我正确理解这一点,我应该创建一个调用的文件 /etc/mongodb.conf并将dbpath设置为/data/db.

我是否还需要删除内容/usr/local/？

我认为这与我的PATH如何设置有关...有人可以向我解释如何在unix中解决这个问题,所以我不会有这个问题吗？

再次感谢!
