哪个是mongodb中的数据库？

Question

下一个问题参考前一个mongodb在ubuntu中存储数据库的位置？

$ 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？我应该转储哪一个？

尝试每个,得到以下错误:

$ 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

此命令将适用于您如果您的dbpath已设置或您的mongoDB服务正在运行此ihtx表示您的dbname

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