Just the error,

[2018-02-25t13:49:33,967] [WARN] [O.e.d.z.zendiscovery     ] [node-191-168-10-173] Not enough master nodes discovered during pinging (found [[candidate{ NODE={NODE-191-168-10-173}{WQUJ4GYUTTEO7M5UXZSBIQ}{19L-SAVFRVQVYYJSKTBP_G}{192.168.1.194}{192.168.1.194:9300}, Clusterstateversion=-1}]], but needed [3]), pinging again

I thought it was because I did not configure SSH, and finally found that the above IP write wrong, and then verify that the SSH is not configured to be OK.

This is the first boot on the top of the print log, the other is the same, less log

Now there's a question that I'm visiting
Http://192.168.10.173:9200/
Http://192.168.10.174:9200/
Http://192.168.10.175:9200/
Can print out the version number, to prove that the correct operation, I tried to shut down a 174, found http://192.168.10.174:9200/can not open, and then, I think there should be a master master, but who is the Lord. Not good to see, below we install the graphical interface head try 2 install Elasticsearch-head

Three machines just need a head to install. 2.1 Adopt Nodejs installation

6.X, Elasticsearch-head cannot be placed in Elasticsearch plugins, modules directory cannot be used Elasticsearch-plugin install

Direct start Elasticsearch can 2.2 install Elasticsearch-head

1. Modify Elasticsearch/config/elasticsearch.yml
2. Add

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

3. Download Elasticsearch-head or git clone to a random folder

Https://github.com/mobz/elasticsearch-head

I was directly downloaded to

[Es@biluos elasticsearch-head-master]$ pwd
/home/es/elasticsearch-head-master

of the Directory

4. Install Nodejs
http://blog.csdn.net/qq_21383435/article/details/79367366

5.cd/home/es/elasticsearch-head-master
6.NPM install-g GRUNT-CLI
Grunt is a handy build tool for packaging, testing, executing, and so on.
