使用
uname -a查看 Linux 系統(tǒng)內(nèi)核與版本，選擇對(duì)應(yīng)的安裝包，
下文以Linux x86_64 / Elasticsearch 8.7為例，演示通過RPM和壓縮包兩種方式的安裝步驟。
1 下載與安裝
Download Elasticsearch
1.1 RPM
Install Elasticsearch with RPM
# 創(chuàng)建并切換目錄
mkdir /data/elastic
cd /data/elastic
# 下載
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.7.0-x86_64.rpm
# 安裝
rpm -ivh elasticsearch-8.7.0-x86_64.rpm
# 查看配置文件位置
rpm -qc kibana
安裝完畢后展示以下信息，記得保存安裝完畢后的 elastic 賬號(hào)密碼
--------------------------- Security autoconfiguration information ------------------------------
Authentication and authorization are enabled.
TLS for the transport and HTTP layers is enabled and configured.
The generated password for the elastic built-in superuser is : bLDOCJP2l5TmLegNt6BN
If this node should join an existing cluster, you can reconfigure this with
'/usr/share/elasticsearch/bin/elasticsearch-reconfigure-node --enrollment-token <token-here>'
after creating an enrollment token on your existing cluster.
You can complete the following actions at any time:
Reset the password of the elastic built-in superuser with
'/usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic'.
Generate an enrollment token for Kibana instances with
'/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s kibana'.
Generate an enrollment token for Elasticsearch nodes with
'/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s node'.
-------------------------------------------------------------------------------------------------
1.2 壓縮包
Install Elasticsearch from archive on Linux or MacOS
# 創(chuàng)建用戶 elastic，其中 -d 和 -m 選項(xiàng)用來為登錄名 elastic 產(chǎn)生一個(gè)主目錄 /home/elastic
useradd -d /home/elastic -m elastic
# 指定用戶 elastic 的口令
passwd elastic
# 創(chuàng)建安裝目錄
mkdir -p /app/elastic
# 更改目錄權(quán)限
chown -R elastic:elastic /app/elastic
# 切換用戶
sudo su - elastic
# 切換目錄
cd /app/elastic
# 下載安裝包
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.7.0-linux-x86_64.tar.gz
# 解壓安裝包
tar -zxvf elasticsearch-8.7.0-linux-x86_64.tar.gz
# 切換解壓后的目錄
cd /app/elastic/elasticsearch-8.7.0

2.2 Elasticsearch 應(yīng)用配置
Configure important Elasticsearch settings
- RPM 安裝的配置文件路徑
vim /etc/elasticsearch/elasticsearch.yml - 壓縮包 安裝的配置文件路徑
vim /../elasticsearch-8.7.0/config/elasticsearch.yml
# Use a descriptive name for your cluster:
cluster.name: elasticsearch-dev
# Use a descriptive name for the node:
node.name: dev-data-1
# 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
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
network.host: 172.16.32.2
# 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
# 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: ["172.16.32.2"]
# Enable security features

xpack.security.transport.ssl:
enabled: true
verification_mode: certificate
keystore.path: certs/transport.p12
truststore.path: certs/transport.p12
# Create a new cluster with the current node only
# Additional nodes can still join the cluster later
cluster.initial_master_nodes: ["dev-data-1"]
# Allow HTTP API connections from anywhere
# Connections are encrypted and require user authentication
http.host: 0.0.0.0
# Allow other nodes to join the cluster from anywhere
# Connections are encrypted and mutually authenticated
transport.host: 0.0.0.0
