{
        "authInfo" : {
                "authenticatedUsers" : [ ],

#3 Step: Configuring Mongo Database users and Role

LC_ALL is the environment variable that overrides all the other localization settings
Note: Below mentioned commands should be run individually one after the other.

$ export LC_ALL=C //
$ mongo
> use admin
> db.createUser({user:"mongoadmin", pwd:"mongoPassword123", roles:[{role:"root", db:"admin"}]})
> exit            //then exit mongo shell to terminal.

#4 Step: Securing public access by enabling MongoDB authentication

Open mongod.service file as shown below

$ sudo vim /lib/systemd/system/mongod.service

Find below-mentioned code

ExecStart=/usr/bin/mongod — config /etc/mongod.conf

Replace with the below code with auth.
