How can I fix "EMPTYUNREACHABLE" when deploying a test suite on my mac?

Question

I am trying to deploy development / testing replication installed on my macbook pro using this document.

http://docs.mongodb.org/manual/tutorial/deploy-replica-set/

I started 3 instances of mongod, each on port 10001, 10002, 10003 I used the configuration file to run mongod. The configuration file below:

rs0: dbpath = /Users/Thomas/mongodb/data/rs0/ port = 10000 logpath = /Users/Thomas/mongodb/log/rs0.log logappend = true replSet = rs0 rs1: dbpath = /Users/Thomas/mongodb/data/rs1/ port = 10001 logpath = /Users/Thomas/mongodb/log/rs1.log logappend = true replSet = rs0 rs2: dbpath = /Users/Thomas/mongodb/data/rs2/ port = 10002 logpath = /Users/Thomas/mongodb/log/rs2.log logappend = true replSet = rs0 

And using the following command to run:

 mongod -f config/rs0.conf mongod -f config/rs1.conf mongod -f config/rs2.conf 

then I connect to it using mongo: mongo localhost: 10001, but when I use the rs.initiate () command to initialize the replica set, that fails.

 > rs.initiate() { "startupStatus" : 4, "info" : "rs0", "errmsg" : "all members and seeds must be reachable to initiate set", "ok" : 0 } 

and check rs.status ()

 > rs.status() { "startupStatus" : 4, "errmsg" : "can't currently get local.system.replset config from self or any seed (EMPTYUNREACHABLE)", "ok" : 0 } 

And the log shows an EMPTYUNREACHABLE error. how can this be solved?

Answer 1

Try setting bind_ip to 127.0.0.1 or add an entry for `bogon 'to your / etc / hosts?

mongodb seems to get the hostname () for the local system, but its not resolvable.

Answer 2

Today I ran into a problem. I was able to run mongodb, but not a replica set. I had to remove the following line from the mongod.conf file

'bind_ip: "127.0.0.1"'

I also realized that the mongod.conf files for mongodb sets and replicas are different and stored in different places, perhaps because I brew installed the latest version of mongodb ?. I found my configuration file with replica settings on the page "/usr/local/etc/mongod.conf".

Answer 3

FYI, I believe that you hit this error in 2.2.0:

https://jira.mongodb.org/browse/SERVER-7367

Now it has been fixed and is scheduled for release in 2.2.1 - the fixes for 2.2.0 basically include ensuring that you use resolvable and accessible addresses for your sets, since 2.2.0 tries to reach even local instances over the network.
