First, install the Java SE environment
Install the Java JDK and configure the JAVA_HOME environment variable before installing the Elasticsearch engine:
1, from www.oracle.com/technetwork… Download and install the Java SE development kit. I downloaded the latest version as shown below:
ElasticSearch is sensitive to the JRE version. An incorrect version will cause ElasticSearch to fail to run. To download the Archive JRE, download the appropriate version from the Java Archive.
2. After the Java SE development package is installed, create the JAVA_HOME environment variable on the server
Environment variable JAVA_HOME, set the variable value to: C:\Program Files\Java\ JDK-11.0.2
On Windows, the “% environment variable name %” is used to obtain the value of the specified environment variable. The JAVA_HOME environment variable is used because the Java SE development package is required for installing ElasticSearch.
Install ElasticSearch
www.elastic.co/downloads/p… Download the corresponding version I downloaded 5.4.0
* Use the version of PHP that corresponds to ElasticSearch!
The ElasticSearch service is enabled
Bat file to install elasticSearch. Wait for a moment, open your browser, enter http://localhost:9200, and display the following screen: ES is successfully installed.
Install Chinese participle IK
Download the ik github.com/medcl/elast…
My ES version is 5.4.0IK select 5.4.0 must find the corresponding version ！！！！！！
Download it and unzip it into a folder
Create an ik folder for elasticSearch-5.4.0plugins \ik
Restart ElasticSearch after success ok!! ElasticSearch service installed successfully!!
Install ElasticSearch within the project
composer require elasticsearch/elasticsearch
Copy the codeThe appropriate version will be automatically loaded! Version 5.4.0 for ElasticSearch
Now elasticSearch and PHP support are installed!
Easy to use in ThinkPHP5
The methods below are some of the official sample integrations
