mongodb Failed: error connecting to db server: no reachable servers

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

You need to provide host option try the following command :

mongoimport --host=127.0.0.1 -d dbName -c collectionName --file output.txt

Answer 2

A temporary workaround is to add the host param to your mongoimport call, letting mongo know that the host is your own machine (127.0.0.1):

mongoimport --host=127.0.0.1

The full command in your case is then:

mongoimport --host=127.0.0.1 \
  --db test --collection restaurants --drop --file dataset.json

Update:

Updating to Mongo >= 3.0.7 should solve the issue

Update 2:

It seems the Bug is still happening for some users.

There's also an open JIRA issue here.

Update 3:

In some cases, this can be caused by Mongo running as a ReplicaSet. To solve this, as far as I've seen, one can either disable the ReplicaSet functionality or reset it. See:

• How to reset MongoDB replica set settings
• How to convert a MongoDB replica set to a stand alone server

Answer 3

To provide the options host and port

mongoimport --host X.X.X.X --port 27017 --db dbName --collection collectionName --file fileName.json --jsonArray

Answer 4

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 
<cluster-name>-shard-0/
<cluster-name>-shard-00-00-obe3i.mongodb.net:27017,
<cluster-name>-shard-00-01-obe3i.mongodb.net:27017,
<cluster-name>-shard-00-02-obe3i.mongodb.net:27017 
--ssl 
--username <User-Name> 
--password <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.

Answer 5

I went ahead and downloaded MongoDB Compass and used the connection string from Atlas for

and that connection worked like a charm.

After that I went ahead and added the data using the Add Data option and uploaded the file which i want to mongoimport

Answer 6

For someone using Mongo Atlas and json file for import into collection:

mongoimport --uri mongodb+srv://<user>:<password>@your-cluster.xxxx.mongodb.net/<db> -c <collection> --file import.json --jsonArray
