MongoError: failed to connect to server

[keshaipad]

Can't understand why:

MacBook-Pro:zenbot macbookpro$ ./reducer.sh

/Users/macbookpro/btc-bot/zenbot/node_modules/motley-mongo/node_modules/mongodb/lib/mongo_client.js:225
          throw err
          ^

it seems you don't have mongodb running.. what do you get if you type mongo in the terminal?

[BarnumD]

If mongo is on a different host (or in the case of docker, a different container) you may need to edit the config.js to specify the correct connection string.

[egorbenko]

if you are using docker replace this line
c.mongo_url = "mongodb://localhost:27017/zenbrain"
with
c.mongo_url = "mongodb://" + process.env.MONGODB_PORT_27017_TCP_ADDR + ":27017/zenbrain"

getting the same error... running this fine in a docker container but want to run it without Docker.

what is the solution?

Use mongod to start MongoDB.
