ubuntu - elasticsearch－head插件安装后，启动问题！

问题描述

1.系统环境：　ubuntu12.04 elasticsearch5.11 node 7.2.1 npm 4.05 2.安装elasticsearch之后，可以启动，能够访问http://localhost:9200返回代码：{ 'name' : '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'}

只在一台主机上安装，只有一个节点。

但是安装完插件head之后，elasticsearch不能启动出现报错.

3．head插件安装，启动之后能够启动，能够使用网址访问到相应的界面。

4.报错内容为：2016-12-16T07:51:20,581[o.e.b.ElasticsearchUncaughtExceptionHandler] [] uncaught exception in thread [main]org.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: Property [elasticsearch.version] is missing for plugin [head]

这是什么原因造成的呢？求大神们答疑解惑！

问题解答

5.1中，elasticsearch-head

不能放在elasticsearch的 plugins、modules 目录下

不能使用 elasticsearch-plugin install

直接启动elasticsearch即可

修改 elasticsearch/config/elasticsearch.yml

添加

http.cors.enabled: truehttp.cors.allow-origin: '*'

下载 elasticsearch-head 或者 git clone 到随便一个文件夹

安装nodejs

cd /path/to/elasticsearch-head

npm install -g grunt-cli

npm install

grunt server

http://localhost:9100/

Enjoy it.

一定要记得添加

http.cors.enabled: truehttp.cors.allow-origin: '*'回答3：
