elasticsearch 8.6.0 버전은 기본적으로 SSL 암호화 통신을 합니다.
저는 현재 설정은 SSL을 사용하지 않는 방법을 이용하겠습니다.
향후 SSL 적용 매뉴얼도 작성해서 올리도록 하겠습니다.
- SSL 암호화 통신 하지 않음
- cluster 설정 사용
- cluster를 사용할 경우 로그: /var/log/elasticsearch/{cluster.name}.log
- cluster를 사용하지 않을 경우 로그: /var/log/elasticsearch/elasticsearch.log
클러스터 설정 사용하지 않을 경우
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
# 클러스터 사용할 경우 아래 항목 활성화
# cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: tmplogsvr
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
# discovery.seed_hosts: ["127.0.0.1"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
# 클러스터 사용할 경우 아래 항목 설정 적용
# cluster.initial_master_nodes: ["tmplogsvr"]
#
# For more information, consult the discovery and cluster formation module documentation.

설정에 맞게 사용 (전체 설정 내용)
# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
# Before you set out to tweak and tune the configuration, make sure you
# understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: tmplogsvr
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /var/lib/elasticsearch
#
# Path to log files:
#
path.logs: /var/log/elasticsearch
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
network.host: 0.0.0.0
#
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["127.0.0.1", "[::1]"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
cluster.initial_master_nodes: ["tmplogsvr"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# --------------------------------- Readiness ----------------------------------
#
# Enable an unauthenticated TCP readiness endpoint on localhost
#
#readiness.port: 9399
#
# ---------------------------------- Various -----------------------------------
#
# Allow wildcard deletion of indices:
#
#action.destructive_requires_name: false
