在另一个Rails应用程序中使用一个Rails应用程序的Elasticsearch服务器

Question

My rails application is running using four ec2 instances. When user hit rails application using url, rails application will be serve to the user using any one of four ec2 instance using ELB.

Elasticsearch server is installed on one of the rails server. How i can use same elasticsearch server which is installed on one server for rest of three rails servers also for searching?

Answer 1

I am using the internal (10.xxx) address for connecting to elasticsearch.

Elasticsearch::Model.client = Elasticsearch::Client.new(host:'10.xxx',port:9200)

As long as you set your inbound rules right you can connect to your elasticsearch instance from any ec2 host.

Make sure that elasticsearch listens on 10.xxx and not only on 127.0.0.1.

put network.host: _site_ in elasticsearch.yml
