Question

I installed mongodb in Ubuntu14.04 server

I was not able to connect to mongodb via \"mongoimport\", \"mongodump\", \"mongostat\", etc. It always show \"no reachable

Answer 1

Adding another answer for those who are struggling with the same issue while using MongoDB Atlas.

I tried to follow the offical guides like Seed with mongorestore and Load File with mongoimport but received the same no reachable servers error.

I tried to change the command arguments over and over - nothing changed.

But then I navigated inside my cluster to the "Command Line Tools" tab and saw the exact command I should run for mongorestore, mongodump, mongoimport,mongoexport etc':

Adding as inline the full command:

mongorestore --host 
-shard-0/
-shard-00-00-obe3i.mongodb.net:27017,
-shard-00-01-obe3i.mongodb.net:27017,
-shard-00-02-obe3i.mongodb.net:27017 
--ssl 
--username  
--password  
--authenticationDatabase admin 

The mongorestore comand can be replaced with mongodump,mongoimport,mongoexport etc'.

(*) Prefer copying the command directly from dashboard because the DNS of the replica-sets might change.

(**) MongoDB shell version v4.2.5.
