1.根据thinkphp版本下载对应的 elasticsearch版本
https://mirrors.huaweicloud.com/elasticsearch/
这里我下载的是8.5.3版本
cd /www/server
wget https://mirrors.huaweicloud.com/elasticsearch/8.5.3/elasticsearch-8.5.3-linux-x86_64.tar.gz
tar -zxvf elasticsearch-8.5.3-linux-x86_64.tar.gz
cd elasticsearch-8.5.3
vi config/elasticsearch.yml
elasticsearch.yml内容如下
# ======================== 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: node-1
node.name: zk-node-1
#
# 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: /path/to/data
path.data: /www/elastic/data
#
# Path to log files:
#
#path.logs: /path/to/logs
path.logs: /www/elastic/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 -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 127.0.0.1
#
# Set a custom port for HTTP:
#
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: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
#cluster.initial_master_nodes: ["node-1", "node-2"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
cluster.initial_master_nodes: ["zk-node-1"]
cluster.routing.allocation.disk.watermark.flood_stage: 99%
cluster.routing.allocation.disk.threshold_enabled: false
添加elastic用户
groupadd elastic
useradd -g elastic elastic
chown -R elastic:elasticelasticsearch-8.5.3
安装ik分词库
https://github.com/medcl/elasticsearch-analysis-ik/releases
指定java_home 17以上
切换到elastic并启动elastic
su elastic
./bin/elastic -d
测试是否启动成功
curl 127.0.0.1:9200
{
"name" : "zk-node-1",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "ASYFm--EQKu_hrqCSOHmVQ",
"version" : {
"number" : "7.10.2",
"build_flavor" : "default",
"build_type" : "tar",

安装elasticsearch可视化工具
https://github.com/qax-os/ElasticHD/releases 自己下载对应系统的版本 这里我安装windows版本的
解压文件后 通过命令行
cd D:\Eshome\esHD （这里替换掉你下载解压后的文件夹目录）
ElasticHD -p 127.0.0.1:9800
在输入框输入elastic地址 如果是本地 则是127.0.0.1：9200，如果是远程地址，则填写相应的ip加端口
