I cannot find a solution for my question so I have to ask. I've made a mongodb cluster in Atlas. Now via shell I want to connect primary replicaset node. Could you please help me?
After connecting my cluster via shell I see this:
MongoDB Enterprise AkademiaWSB-shard-0:PRIMARY>
Meaby it is primary node but how to switch between nodes? screen of my replica set
You need to connect the instance with URI format.
The below example uses 3.6. It will be the same for higher versions too.
https://docs.mongodb.com/v3.6/reference/connection-string/
Please refer the above connection string format.
A replica set without authentication enforced.
mongodb://mongodb0.example.com:27017,mongodb1.example.com:27017,mongodb2.example.com:27017/admin?replicaSet=myRepl
A replica set with authentication enforced
mongodb://myDBReader:D1fficultP%40ssw0rd@mongodb0.example.com:27017,mongodb1.example.com:27017,mongodb2.example.com:27017/admin?replicaSet=myRepl
The shell shows you correctly that you are connected to Primary.
Why do you need to connect to other nodes? You should read/write from primary (as a basic principle).
If your replica-set members are host on a remote you can connect the other mongo's shell used:
mongo --host mongodb0.example.com:27018
Also if you want to locate your replica-set Primary server you just need to connect to one of your replicas shell and run rs.stats(). Then connect to the primary node used the command above.
Good Luck! ;)
