Install MongoDB As A Service In Windows

1. Download MongoDB from https://www.mongodb.org/

2. Extract the contents of the zip file into C:\mongodb

3. Add MongoDB to the Windows path. Edit your environment variable. Append this: C:\mongodb\bin;

4. Create a configuration file C:\mongodb\mongod.conf and add these lines:

dbpath=C:\mongodb\data\db
logpath=C:\mongodb\log\mongo.log
verbose=vvvvv

Note: you have to manually create both c:\mongodb\data\db and c:\mongodb\log directory.

5. Open the command prompt as administrator and run the following commands:

mongod -f c:\mongodb\mongod.conf
mongod -f c:\mongodb\mongod.conf --install

6. Start MongoDB

net start mongodb

From now on, mongodb service will run automatically every time the PC is restarted.
