环境

php 7.2
elasticsearch 6.2 下载
elasticsearch-php 6 下载

安装 elasticsearch

下载源文件，解压，重新建一个用户，将目录的所属组修改为此用户，因为 elasticsearch 无法用 root 用户启动。

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.3.tar.gztar zxvf elasticsearch-6.2.3.tar.gz
useradd elasticsearch
passwd elasticsearch
chown -R elasticsearch:elasticsearch elasticsearch-6.2.3
mv elasticsearch-6.2.3 /usr/local/elasticsearch-6.2.3
yum install java-1.8.0-openjdk.x86_64  //安装jdk
su elasticsearch
cd /usr/local/elasticsearch-6.2.3
./bin/elasticsearch  // 启动

安装 PHP 扩展

我这里使用的是 composer 安装 elasticsearch-php。在 composer.json 文件中加入 "elasticsearch/elasticsearch": "~6.0"，执行 composer update。

tp5使用实例
