First of all, Thanks David Makogo for guiding to formulate a proper answer , I too had same problem and sorted out following couple of steps, therefore thought to share the steps and information related to this issue
Based on the support of underlying OS's built-in init System (a service management system in Linux)
we can perform/execute systemctl or service commands
Mainly, There are two types : namely systemd (systemctl) or System V Init (service)
WSL installed Ubuntu falls into init category , Anyway, you can check which type it by
**ps --no-headers -o comm 1**
Currently ,WSL does not support for systemd and no default scripts installed during installation of mongoDB
Anyway, we can execute service commands but we have to install init scripts beforehand, you can download & set permissions
**curl https://raw.githubusercontent.com/mongodb/mongo/master/debian/init.d |
sudo tee /etc/init.d/mongodb >/dev/null
sudo chmod +x /etc/init.d/mongodb**
Also create & set directories where you want to store data
**mkdir -p ~/data/db
mongod --dbpath ~/data/db #set to path while running mongo**
Next you can attempt the service commands based on success of all above points
**sudo service mongodb start/stop/status**
Also you can refer official microsoft guides for install mongoDB and differences
