Elasticsearch installation Configuration

1. Download the latest version of Elasticsearch from elastic official website, currently the latest version is V2.3.3.

2. Unzip

Tar zxvf elasticsearch-2.3.2.tar.gz

3. Switch to the Elasticsearch Bin directory and start the service.

./elasticsearchexception in thread "main" Java.lang.RuntimeException:don ' t run Elasticsearch as root.

At startup, Elasticsearch will report the following error because Elasticsearch does not allow the root account to be used to start the service for security reasons.

4. Create a new account

[[email protected] bin]# useradd elasticsearchuser[[email protected] bin]# passwd elasticsearchuserchanging password for User Elasticsearchuser. New Password:bad Password:is too simpleretype new Password:passwd:all authentication tokens updated successfully. [Email protected] bin]# usermod-g root Elasticsearchuser

5. Restart the service.

6. Service can also be run as daemon

./elasticsearch-d

You can also specify the PID at startup

./elasticsearch-d-P PID

7. Visit in the browser and reconfirm that the service is intact, but only if you modify/config/elasticsearch.yml, find Network.host to add a line below, and then access Http://10.0.0.5:9200/in the browser.

network.host:10.0.0.5

The browser displays the following:

{"Name": "Gargouille", "cluster_name": "Elasticsearch", "version": {"number": "2.3.2", "Build_hash": "B9e4 A6acad4008027e4038f6abed7f7dba346f94 "," Build_timestamp ":" 2016-04-21t16:03:47z "," Build_snapshot ": false," Luc Ene_version ":" 5.5.0 "}," tagline ":" You Know, for Search "}

At this point, the Elasticsearch installation started, more detailed operation is also later.
