mongo连接拒绝osx

Question

I'm trying to install mongo. I ran the following:

 $sudo chown -R [username] /usr/local
~ $sudo chmod -R u+w /usr/local
~ $brew link mongodb
Linking /usr/local/Cellar/mongodb/3.0.2... 14 symlinks created

I ran mongo and got the following:

~ $mongo
MongoDB shell version: 3.0.2
connecting to: test
2015-04-14T09:21:29.095-0400 W NETWORK  Failed to connect to 127.0.0.1:27017, reason: errno:61 Connection refused
2015-04-14T09:21:29.097-0400 E QUERY    Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed
at connect (src/mongo/shell/mongo.js:179:14)
at (connect):1:6 at src/mongo/shell/mongo.js:179
exception: connect failed

Not sure what to do.

Answer 1

If you don't specify a db address,

$ mongo <db-address>

mongo gets lost in the woods. If you want a mongo shell without a db,

$ mongo -nodb

does the trick.

If you're running locally, you probably either didn't specify a port (if the server isn't running on the default port 27107) or you just don't have a server running. The mongo command starts a shell, not the server. You need to

$ mongod --dbpath <path to data directory>

to get the server running. Once it's up,

$ mongo

should run locally with no problems.
