php7使用elasticsearch

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‘);

2、api使用
