Just chande mongosh by mongod

sorry, you are already inside the instance so you can use the command rs.initiate(), and then add the necessary members with rs.add()

Hi @RAJYAVARDHAN_SINGH_RATHORE ,
you’ re trying to start a replica set inside the mongoshell, with the mongosh command and is wrong!
You need to do something like that (for example in linux):

[root@com ~]# mongod --logpath "path_for_log" --dbpath "path_for_data" --replSet "name" --bind_ip 0.0.0.0 --fork  etc...

I hope is useful!

Regards
