Set up Elasticsearch

Install

Download and install archive for MacOS

The MacOS archive for Elasticsearch v7.0.0 can be downloaded and installed as follows:

(MacOS에서 Elasticsearch 설치 경로 : /Users/dhkdn9192/elasticsearch-7.0.0)

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.0.0-darwin-x86_64.tar.gz
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.0.0-darwin-x86_64.tar.gz.sha512
shasum -a 512 -c elasticsearch-7.0.0-darwin-x86_64.tar.gz.sha512 
tar -xzf elasticsearch-7.0.0-darwin-x86_64.tar.gz
cd elasticsearch-7.0.0/

Home directory의 .bash_profile 파일에 아래와 같이 ES_HOME을 설정한다

# Elasticsearch
export ES_HOME=/Users/dhkdn9192/elasticsearch-7.0.0

Installation for Linux

The Linux archive for Elasticsearch v7.0.0 can be downloaded and installed as follows:

curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.0.0-linux-x86_64.tar.gz
tar -xvf elasticsearch-7.0.0-linux-x86_64.tar.gz
cd elasticsearch-7.0.0/bin

실행 시에는 아래와 같이 bin 안의 파일을 실행시킨다

./elasticsearch

백그라운드로 실행시키기 위해 다음과 같이 start.sh 스크립트를 만들어 사용하면 편리하다

#! /bin/bash
nohup /opt/elasticsearch-7.0.0/bin/elasticsearch > nohup_elasticsearch.out &

서비스 종료 시에는 해당 프로헤스를 kill하면 된다

Enale automatic creation of X-Pack indices

X-Pack will try to automatically create a number of indices within Elasticsearch. By default, Elasticsearch is configured to allow automatic index creation, and no additional steps are required

$ES_HOME/config/elasticsearch.yml 파일에 다음과 같은 설정을 추가한다

action.auto_create_index: .monitoring*,.watches,.triggered_watches,.watcher-history*,.ml*

External network config

외부에서 Elasticsearch에 접근 가능하도록 하려면 $ES_HOME/config/elasticsearch.yml에 다음 설정을 추가한다. 단, 외부접근 가능한 공인 IP가 있어야 한다

network.bind_host: 0.0.0.0

당연히 포트가 열려있는지, 방화벽을 내렸는지 확인해야 한다

netstat -tnlp
systemctl status firewalld

Important configuration

다음 설정들이 필요하다 (싱글노드를 상정함)

cluster.name: my-application
node.name: node-1
path.data: /opt/elasticsearch-7.0.0/var/lib/elasticsearch
path.logs: /opt/elasticsearch-7.0.0/var/log/elasticsearch
bootstrap.memory_lock: true
http.port: 9200
discovery.seed_hosts: ["localhost"]
cluster.initial_master_nodes: ["localhost"]

Run from command line

./bin/elasticsearch

Check that Elasticsearch is running

You can test that your Elasticsearch node is running by sending an HTTP request to port 9200 on localhost:

command line에서 아래와 같이 curl을 입력한다

curl -X GET "localhost:9200/"

아래와 같은 응답을 받아야 정상이다

{
  "name" : "gimdonghyeog-ui-MacBook-Pro.local",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "RKUE3gwASMGDpp9PnOpZTA",
  "version" : {
    "number" : "7.0.0",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "b7e28a7",
    "build_date" : "2019-04-05T22:55:32.697037Z",
    "build_snapshot" : false,
    "lucene_version" : "8.0.0",
    "minimum_wire_compatibility_version" : "6.7.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

Running as a daemon

run as a daemon by -d option, and record the process ID in a file by -p option

./bin/elasticsearch -d -p pid

Log messages can be found in the $ES_HOME/logs/ directory.

Shutdown Elasticsearch

To shut down Elasticsearch, kill the process ID recorded in the pid file:

pkill -F pid
