我在mongodb中的哪个数据库? [英] Which is my database in mongodb?

问题描述

参考上一个问题的下一个问题 mongodb在ubuntu中将databse存储在哪里?

Next question in reference with previous one Where does mongodb store databse in ubuntu?

$ cd /var/lib/mongodb/
$ ls
ihtx.0  ihtx.1  ihtx.ns  journal  local.0  local.ns  mongod.lock

在这里，我可以看到ihtx.0 ihtx.1 ihtx.ns三个具有相同名称的文件.这是我通常在mongo shell中看到的mydatabase之一? 我应该丢哪一个?

Here, I can see ihtx.0 ihtx.1 ihtx.ns three files with the same name. Here which one is mydatabase which I usually see in mongo shell? which one should I dump ?

每次尝试，都会收到以下错误消息:

Tried each, getting following error :

$ mongodump --dbpath /var/lib/mongodb/ihtx.XX --out /home/user/Desktop/

If you are running a mongod on the same path you should connect to that instead of direct data file access

推荐答案

此命令将为您工作 如果设置了dbpath或mongoDB服务正在运行 这里的ihtx表示您的dbname

This command will work for you If your dbpath is set or you mongoDB service is Running here ihtx denotes your dbname

$ mongodump -d ihtx --out /home/user/Desktop/intxDB
