1、安装
官网下载地址：https://www.elastic.co/downloads/elasticsearch
# 解压到非root目录，运行时使用非root账号且必须安装java环境
yum install java
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.3.tar.gz
tar zxvf elasticsearch-6.2.3.tar.gz
useradd elasticsearch
password elasticsearch
chown elasticsearch:elasticsearch elasticsearch-6.2.3
cd elasticsearch-6.2.3
nohup ./bin/elasticsearch & #设置成常驻进程
# php扩展库引入 composer.json
{ "require": { // ... "elasticsearch/elasticsearch": "~6.0" // ... } }
# 测试数据导入
create table articles(
id int not null primary key auto_increment,
title varchar(200) not null comment ‘标题‘,
content text comment ‘内容‘
);
insert into articles(title, content) values (‘Laravel 测试1‘, ‘我的宝马多少马力‘),
(‘我的宝马发动机多少‘, ‘我的保时捷马力不错‘),
(‘Laravel 测试3‘, ‘我的宝马发动机多少‘);
