# Docker-compose 기반 Elasticsearch, logstash, kibana설치 (Cluster + xpack인증 + curator)
## 0. 사전작업
### ELK 폴더 생성
- docker-elk (root)
- kibana
- config
- logstash
- config
- pipeline
## 1. docker-compose.yml 작성 (xpack 인증 전)
```yml
version: '3.7'
services:
elastic01:
user: elasticsearch
image: docker.elastic.co/elasticsearch/elasticsearch:7.17.7
container_name: es01
environment:
- node.name=es01-node
- cluster.name=es-docker-cluster
- cluster.initial_master_nodes=es01-node,es02-node,es03-node

- node.data=true
# - discovery.seed_hosts: ["es01-node:9300", "es02-node:9301", "es03-node:9302"]

data03:

backup:

networks:

driver: bridge
```
## 2. 기타 설정 파일 작성
### 1. logstash.yml 작성
```yml
http.host: 0.0.0.0
node.name: logstash
```
### 3. kibana.yml 작성
```yml
server.name: kibana
server.port: 5601
server.host: '0.0.0.0'
elasticsearch.username: elastic
elasticsearch.password: changeme
elasticsearch.hosts: ['http://118.220.143.175:9200','http://118.220.143.176:9201','http://118.220.143.176:9202']
xpack.security.enabled: true
#server.cors: true
#server.cors.origin: ['*']
```
### 4. logstash.conf 작성
```yml
input {
kafka {
bootstrap_servers => "118.220.143.175:9091,118.220.143.176:9091,118.220.143.176:9092"
topics => ["sacp2","sacp3","sacp4","sacp6"]
consumer_threads => 1
decorate_events => true
}
beats {
port => 5044
}
tcp {
port => 50000
}
}
output {
elasticsearch {
index => "spring-%{[@metadata][kafka][topic]}-%{+YYYY-MM-dd}"
user => "elastic"
password => "changeme"
hosts => ["118.220.143.175:9200","118.220.143.176:9201","118.220.143.176:9202"]
}
}
```
## 3. 컨테이너 실행
```bash
# 경로 이동 후 컨테이너 생성 및 실행
cd /opt/SACP-INSTALL/docker-elk/ && docker-compose build && docker-compose up -d
# 컨테이너 로그 확인
docker logs es01
### 로그의 오류
# 내용 : vm.max_map_count is too low, access denied "modifyThread" ..
# Host에서 max_map_count 수정
cat /proc/sys/vm/max_map_count
65530 -> 262144
```
## 4. X-pack 용 CA 생성
```bash
# 컨테이너 접속
docker exec -it es01 bash
# CA 수행 및 keystore.password 입력 (예. todnRkd1% )
bin/elasticsearch-certutil ca
# cert 수행 및 truststore.password 입력 (예. todnRkd1% )
bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12
# 생성 경로 확인
find / -name "elastic-stack-ca.p12"
--> /usr/share/elasticsearch/elastic-stack-ca.p12
find / -name "elastic-certificates.p12"
--> /usr/share/elasticsearch/elastic-certificates.p12
# 컨테이너 접속 종료
exit
```
## 5. 컨테이너에서 elastic-certificates.p12 파일 꺼내오기 및 권한 변경
```bash
# Elastic 컨테이너에서 elastic-certificates.p12 파일 가져오기
docker cp es01:/usr/share/elasticsearch/elastic-certificates.p12 /opt/SACP-INSTALL/docker-elk/elastic-certificates.p12
# elastic-certificates.p12 파일 권한 변경
chmod 777 elastic-certificates.p12
```
## 6. docker-compose.yml 수정 (최종본)
> **- user: elasticsearch 부분 중요함 (elasticsearch는 root로 실행하면 안됨)**
> **- xpack.securit 부분 추가**

cd /opt/SACP-INSTALL/docker-elk/ && docker-compose build && docker-compose up -d
# 컨테이너 로그 확인
docker logs es02

> http://118.220.143.175:5601/app/dev_tools#/console
## 10. Curator 설치
- [[python-pip 설치]]
- Curator 설치 (임시, docker에 포함 시켜야 함)
```bash
# curator 다운로드(curator-7.0.zip)
https://github.com/elastic/curator/releases
# pytion 필수 모듈 설치 확인
pip list
voluptuous, cx_Freeze, click, elasticsearch7
# curator 압축푼 폴더로 이동
# curator 설치
python3 setup.py install
# curator 버전 확인
curator --version
```
