MongoDB的数据/ DB没有找到

Question

我给这个路径进行数据/ DB

/usr/local/Cellar/mongodb/3.2.6/data/db 

接下来的步骤是为了建立一个绑定到MongoDB的文件夹

sudo mongod --directoryperdb --dbpath /usr/local/Cellar/mongodb/3.2.6/data/db --logpath /usr/local/Cellar/mongodb/3.2.6/log/mongodb.log --logappend -rest 

当初始化须藤mongod的制作在终端出现以下错误：

2016-06-08T14:45:06.970+0200 I CONTROL [initandlisten] MongoDB starting : pid=8107 port=27017 dbpath=/data/db 64-bit host=iMac-Krystyna-2.local

你能解释什么是错的，也许显示一些常见的实践冰，以便与MongoDB正常工作？

Answer 1

您需要以root身份创建此目录

要么需要使用sudo， sudo mkdir -p /data/db

或者您需要做su - 才能成为超级用户，然后用mkdir -p /data/db

创建目录

Answer 2

MongoDB尝试在系统的根目录下找到data/db文件夹。尝试在/ data/db下创建文件夹。
