Running the following command removes all the installed packages for MongoDB.
sudo apt-get purge mongodb-org*
3. Remove MongoDB Logs
Any logs for MongoDB, by default, is written to the location /var/log/mongodb/. Remove /var/log/mongodb/ and its sub-directories recursively.
sudo rm -r /var/log/mongodb
4. Remove MongoDB Databases
Any databases created in MongoDB, by default, is written to the location /var/lib/mongodb/. Remove /var/lib/mongodb/ and its sub-directories recursively.
sudo rm -r /var/lib/mongodb
If you have created any other directories for MongoDB databases, you may also remove them.
