Reasons: 1, the new version is not allowed to start with root, 2, the software directory does not have the corresponding permissions

Resolve:

Groupadd esuseradd-g es espasswd es

Restart:

Install the plug-in: elasticsearch-head (is the display page in the front of the cluster)

Change to the bin directory to execute

. / plugin install mobz/elasticsearch-head

Page display: http://localhost/_plugin/head

Test:

A json data appears in curl http://localhost:9200 indicating that the startup is successful, as follows

{

"status":

"name": "Omen"

"version": {

"number": "1.1.1"

"build_hash": "f1585f096d3f3985e73456debdc1a0745f512bbc"

"build_timestamp": "2014-04-16T14:27:12Z"

"build_snapshot": false

"lucene_version": "4.7"

}

"tagline": "You Know, for Search"

}

Install the plug-in: elasticsearch-kopf

Execute the command:

. / plugin install lmenezes/elasticsearch-kopf

Page display: http://localhost/_plugin/bigdesk/

4, install kibana

Tar zxvf kibana-4.6.3-linux-x86_64.tar.gz-C / opt

Modify configuration

Because you are on the same server as elasticsearch, you only need to change the link address of elasticsearch

Elasticsearch_url: http://localhost:9200

Start

Bin/kibana-p 5601 > / dev/null 2 > & 1 &

It means to start on port 5601

Then access it through http://ip:5601.
