【搜索技术】elasticsearch－head插件安装后，启动问题！

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,

}

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。

这是什么原因造成的呢？求大神们答疑解惑！

回答

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

安装 elasticsearch-head

  1. 修改 elasticsearch/config/elasticsearch.yml

  2. 添加

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

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

  4. 安装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.

一定要记得添加

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

ES 5.2.2 版本， 如 member 操作后，仍然报错，不知道是什么原因了？
