1.根据thinkphp版本下载对应的 elasticsearch版本

https://repo.huaweicloud.com/elasticsearch/

这里我下载的是7.10.2版本

cd /www/server
wget https://repo.huaweicloud.com/elasticsearch/7.10.2/elasticsearch-7.10.2-linux-x86_64.tar.gz
tar -zxvf elasticsearch-7.10.2-linux-x86_64.tar.gz
cd elasticsearch-7.10.2
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 elasticsearch:elasticsearch elasticsearch-7.10.2

安装ik分词库

https://github.com/medcl/elasticsearch-analysis-ik/releases

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",

通过应用地址插入数据到elastic

HOST/api.php/Elastic/create

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
