ubuntu - elasticsearch－head插件安裝後，啟動問題！

Question

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。

4.錯報內容為：

這是什麼原因造成的呢？求大神們答疑解惑！

Answer 1

5.1中，elasticsearch-head

• 不能放在elasticsearch的 plugins、modules 目錄下

• 不能使用 elasticsearch-plugin install

直接啟動elasticsearch即可

安裝 elasticsearch-head

1. 修改 elasticsearch/config/elasticsearch.yml

2. 添加

   http.cors.enabled: true
   http.cors.allow-origin: "*"

3. 下載 elasticsearch-head 或 git clone 到隨便一個資料夾

4. 安裝nodejs

5. cd /path/to/elasticsearch-head

6. npm install -g grunt-cli

7. npm install

8. grunt server

9. http://localhost:9100/

10. Enjoy it.

Answer 2

一定要記得加入

http.cors.enabled: true
http.cors.allow-origin: "*"
