Ubuntu 15.10 elasticsearch 2.3無法連接到本地端口9200：連接被拒絕

Question

我剛剛在OSX El Capitan和Ubuntu 15.10上安裝了相同版本的elasticsearch，2.3。該命令curl -XGET 'http://localhost:9200/'完全在OSX，但在Ubuntu 15.10是給我這個錯誤：

root@levilinode:~# curl -XGET 'http://localhost:9200/' 
curl: (7) Failed to connect to localhost port 9200: Connection refused 

任何企圖使用與Linux的有關文件/etc/elasticsearch/elasticsearch.yml參數network.bind_host和/或network.host中設置的所有職位，以解決它0.0.0.0或127.0.0.1不成功。

我該如何讓它工作？
