ubuntu - elasticsearch－head插件安裝後，啟動問題！
1.系統環境：
ubuntu12.04 elasticsearch5.11 node 7.2.1 npm 4.05
2.安裝elasticsearch之後，可以啟動，能夠存取http://localhost:9200
回傳代碼：asticsearch之後，可以啟動，能夠存取http://localhost:9200
傳回碼D7ff-uK",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "bl9WuKWVQ6m0TAxHM3UhgA",
"version" : {
"number" : "5.1.1",
"build_hash" : "5395e21",
"build_date" : "2016-12-06T12:36:15.409Z",
"build_snapshot" : false,
"lucene_version" : "6.3.0" "tagline" : "You Know, for Search"
}
只在一台主機上安裝，只有一個節點。
但是安裝完插件head之後，elasticsearch無法啟動出現報錯.3． head外掛安裝，啟動之後能夠啟動，能夠使用網址存取對應的介面。
