How to start elasticsearch and how to use the elasticsearch-head plug-in access, I believe that many inexperienced people do not know what to do, so this article summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

1. Download elasticsearch-6.1.3 and modify the configuration file vi config/elasticsearch.yml

Cluster.name=es_cluster

Node.name=node-1

Path.data=/usr/local/elasticsearch/elasticsearch-6.1.3/data

Path.logs=/usr/local/elasticsearch/elasticsearch-6.1.3/logs

Network.host=192.168.135.130

Network.port=9200

2. Start ES:

. / bin/elasticsearch-v

Prompt cannot run elasticsearch as root

3. Create elasticsearch user groups and elasticsearch users

Groupadd elasticsearch

Useradd elasticsearch-g elasticsearch-p elasticsearch

4. Change the user and group of the Elasticsearch folder and internal files to elasticsearch

Chown-R elasticsearch:elasticsearch / usr/local/elasticsearch

5. Switch elasticsearch

Su elasticsearch

6. Start elasticsearch

. / bin/elasticsearch-v

Error prompted: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

7. Switch to root user to modify the configuration sysctl.conf

Vi / etc/sysctl.conf

Add vm.max_map_count=262144 at the end

Then execute: sysctl-p

8. Restart elasticsearch and start it successfully

. / bin/elasticsearch-d

9. Install the head plug-in

Version 5. 0 can be installed by plugin name, and can be run independently after 5. 0.

Git clone git://github.com/mobz/elasticsearch-head.git

Cd elasticsearch-head

Npm install

Npm run start

Symbolic links should be made during installation: ln-s / usr/bin/nodejs / usr/bin/node
