errors in importing json file in mongo db

Question

After typing mongod I got the log below:

2015-11-21T21:51:11.424-0800 I JOURNAL  [initandlisten] journal dir=/data/db/journal
2015-11-21T21:51:11.424-0800 I JOURNAL  [initandlisten] recover : no journal files present, no recovery needed

It seems like I am having a warning and an error but is connected.

Now, I'm following MongoDB's document to test out how the database works. In one of the tutorials, it tells me to import a json file into my mongo db.

I input the following:

mongoimport --db test --collection restaurants --drop --file primer-dataset.json

and the result is :

2015-11-21T21:57:36.533-0800    [........................] test.restaurants 0.0 B/11.3 MB (0.0%)
2015-11-21T21:57:37.066-0800    Failed: error connecting to db server: no reachable servers
2015-11-21T21:57:37.066-0800    imported 0 documents

Can anyone tell me how to fix this problem?

I did brew update to update everything. So my mongodb version is 3.0.7 (the latest one) And I'm in development mode using homebrew.

have you started mongo server? with mongod?

As the error message says:

Failed: error connecting to db server: no reachable servers

The first step would be to test, whether the MongoDB server can be reached by hand. To do that, type

mongo

in a command line shell. If it does not work, the problem might be due to a firewall setting. (The MongoDB port, which is 27017 by default, might be blocked).

Also, you gave the mongod command and the output. To make sure that mongod is still running, you can type

ps aux | grep mongod

in the shell.

@Kahsn if this is not the completely working solution then you should post your answer which can be useful to future users and accept it. That is how things work around here.

It was a stupid mistake on not running two terminals separately. I was using one terminal to do the operations. I dumped all connections first and connected to the database and opened new tab for a terminal to import the data. And it worked.
