Step 1. 사전 필수 패키지 설치
- 우선 시스템 패키지를 업데이트 하고, HTTPS와 관련된 패키지를 설치한다.
$ sudo apt update
$ sudo apt install apt-transport-https
- 자바를 설치한다.
$ sudo apt install openjdk-11-jdk
$ java -version
openjdk version "11.0.14.1" 2022-02-08
OpenJDK Runtime Environment (build 11.0.14.1+1-Ubuntu-0ubuntu1.20.04)
OpenJDK 64-Bit Server VM (build 11.0.14.1+1-Ubuntu-0ubuntu1.20.04, mixed mode, sharing)
- 자바 환경 변수를 설정하기 위해 아래와 같이 에디터를 입력한다.
$ sudo vi /etc/environment
JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"
$ source /etc/environment
$ echo $JAVA_HOME
/usr/lib/jvm/java-11-openjdk-amd64
Step 2. ElasticSearch 설치
$ wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
OK
$ sudo sh -c 'echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" > /etc/apt/sources.list.d/elastic-7.x.list'
$ sudo apt-get update
Hit:1 https://artifacts.elastic.co/packages/7.x/apt stable InRelease
Hit:2 http://security.ubuntu.com/ubuntu focal-security InRelease
Hit:3 http://archive.ubuntu.com/ubuntu focal InRelease
Hit:4 http://archive.ubuntu.com/ubuntu focal-updates InRelease
Hit:5 http://archive.ubuntu.com/ubuntu focal-backports InRelease

Step 3. Elasticsearch 서비스 시작
- 이번에는 elasticsearch 서비스를 시작한다.
$ sudo systemctl start elasticsearch
- 만약 아래와 같은 에러 메시지가 뜬다면, 추가해야 한다.
System has not been booted with systemd as init system (PID 1).
Can't operate. Failed to connect to bus: Host is down
$ sudo -b unshare --pid --fork --mount-proc /lib/systemd/systemd --system-unit=basic.target
$ sudo -E nsenter --all -t $(pgrep -xo systemd) runuser -P -l $USER -c "exec $SHELL"
$ sudo systemctl enable elasticsearch
Synchronizing state of elasticsearch.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable elasticsearch
Created symlink /etc/systemd/system/multi-user.target.wants/elasticsearch.service → /lib/systemd/system/elasticsearch.service.
$ sudo systemctl start elasticsearch
$ curl -X GET "localhost:9200/"
