Elasticsearch SocketError（getaddrinfo：名称或服务未知）

Question

I'm using the Tire gem in Ruby on Rails to use Elasticsearch for searching. On my local machine it works great.

On my staging server I (randomly?) get this error: SocketError (getaddrinfo: Name or service not known)

Sometimes it works great and is very fast, and sometimes it just throws that error.

Elasticsearch is running on the same server and the url it uses is: http://localhost:9200

I have this in my hosts file:

127.0.0.1   staging-server.mydomain.com staging-server

Where subdomain and domain are set correctly.

What could be the cause of the errors and why does it only happen sometimes?

Answer 1

I had to add

127.0.0.1       localhost

to my hosts file...
