Now, we got the following up and running, we will intialize the replicationSet MuneTakaHome

¶Step 1

• cretae siteRootAdmin pwd: "b2nnnnnnn" with root role in admin database.
  • the most powerful built-in role for MongoDB is the "root" role. The "root" role grants superuser privileges, allowing a user with this role to perform any action on the database, including administrative actions like creating and modifying users, managing roles, and performing administrative tasks.
