Rails：searchkick gem和Amazon EC2实例，Faraday :: ConnectionFailed

Question

I have created a amazon ec2 instance and successfully logged into the instance via ssh . And now I'm trying to to reindex a model from rails c with Model.reindex , but I'm getting the following error:

Faraday::ConnectionFailed: Failed to open TCP connection to localhost:9200 (Connection refused - connect(2) for "localhost" port 9200)

I have added all the tcp ports(80,22,5432,433,9200,9300) to the appropriate security groups.

Also I have edited the /etc/elasticsearch/elasticsearch.yml file with following information:

cluster.name: esonaws
bootstrap.mlockall: true
network.host: xxx.xx.xx.xx(this is the instance private ip)
http.port: 9200
discovery.zen.ping.unicast.hosts: xxx.xx.xx.xx(this is the instance private ip)

and then did a sudo service elasticsearch restart , the elasticsearch starts ok, but when I try to reindex again the same error pops up again.

btw when I do this inside the ssh curl localhost:9200/_cluster/health?pretty I get this:

curl: (7) Failed to connect to localhost port 9200: Connection refused

but if I use the private ip of the amazon ec2 instanceit works and returns all the cluster information.

curl http://xxx.xx.xx.xx:9200/_cluster/health?pretty^C

Any ideas what I might be missing here and how to get this to work?

Answer 1

Elasticsearch binds to network.host , so if you want to use localhost instead of the private ip, you need to use network.host: _local_ .
