elasticsearch 8.17.3部署文档

elasticsearch 8.17.3部署文档

一、架构拓扑

ip主机名角色
192.168.241.151slave1master
192.168.241.152slave2node1
192.168.241.153slave3node2

二、安装包下载——分别下载上传至所有的节点

下载地址https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.17.3-linux-x86_64.tar.gz

##可以使用wget
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.17.3-linux-x86_64.tar.gz

三、master节点部署

3.1 调整服务器参数
 cat >> /etc/security/limits.conf << EOF
* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096
EOF
echo "vm.max_map_count=655360" >> /etc/sysctl.conf
sysctl  -p
useradd elastic
echo "elastic" | passwd --stdin elastic
3.2 解压并赋权
tar xf elasticsearch-8.17.3-linux-x86_64.tar.gz  -C /opt/
ln -s /opt/elasticsearch-8.17.3 /opt/elasticsearch
chown -R elastic:elastic /opt/elasticsearch*
su elastic
cd /opt/elasticsearch
3.3 修改配置文件

vi /opt/elasticsearch/config/elasticsearch.yml

# ======================== 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: myes
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: slave1
#
# 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: /home/elastic/es/data
#
# Path to log files:
#
path.logs: /home/elastic/es/logs
#
# ----------------------------------- 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: ["slave1", "slave2", "slave3"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
cluster.initial_master_nodes: ["slave1"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Allow wildcard deletion of indices:
#
#action.destructive_requires_name: false
3.4 启动es-master
/opt/elasticsearch/bin/elasticsearch

显示下图表示初始化成功，图中包含账号密码
在这里插入图片描述

浏览器输入https://192.168.241.150:9200验证
输入账号elastic
密码BOOIaTVR1B78EqALY*e1
在这里插入图片描述

3.5 调整配置

首次启动使用/opt/elasticsearch/bin/elasticsearch命令可以帮助我们自动生成证书以及账号密码，若使用其他命令需要自己使用bin/elasticsearch-reset-password -u elastic设置密码
启动后可以查看配置文件目录会生成certs目录
使用ctrl + c 退出 ，查看新的配置文件注释掉cluster.initial_master_nodes: [“slave1”]
