Elasticsearch错误无法连接到master - 没有到主机的路由

当我用命令:运行elasticsearch 0.90.0时bin/elasticsearch -f,我收到此错误:

我没有安装logstash.当我访问时localhost:9200,我得到了

{
  ok: true,
  status: 503,
  name: "Haywire",
  version: {
    number: "0.90.0",
    snapshot_build: false
  },
  tagline: "You Know, for Search"
}

任何人都可以帮我解决这个问题吗？
