2. Step 2: Create the directory "D: \ mongodb.pdf", decompress the downloaded installation package, find the directory "all-part. EXE", and copy it to the directory you just created.
3. Step 3: create a "data" folder under the "D: \ MongoDB" Directory, which will be used as the root folder for data storage.

Configure the Mongo Server:

Data warehouse server d.exeand management tool cmd.exe

Open the CMD window and enter the command as follows:

> D:

> Cd D: \ MongoDB

> Mongod -- dbpath D: \ MongoDB \ data
