PHP扩展安装
1. 环境要求：PHP_VERSION >= 5.3.9，composer工具
2. 在E盘新建文件夹命名为elastic,，拷贝composer.phar到
E:/elastic目录下面
3. 打开命令行窗口，进入E:/elastic
4. 在命令行运行：
php composer.phar require elasticsearch/elasticsearch
5. 此时E:/elastic目录下会出现一个vendor目录，安装成功
6. 使用方法：
require 'vendor/autoload.php';
$client = new Elasticsearch\Client();
创建索引
- include('./vendor/autoload.php');
- $elastic = new Elasticsearch\Client();
- $index[‘index’] = ‘log’; //索引名称
- $index[‘type’] = ‘ems_run_log’; //类型名称
- $data[‘body’][‘settings’][‘number_of_shards’] = 5; //主分片数量
- $data[‘body’][‘settings’][‘number_of_replicas’] = 0; //从分片数量
- $elastic->indices()->create($index);
插入索引数据
- include('./vendor/autoload.php');
- $elastic = new Elasticsearch\Client();
- $index[‘index’] = ‘log’; //索引名称
- $index[‘type’] = ‘ems_run_log’; //类型名称
- $index[‘id’] = 1 //不指定id，系统会自动生成唯一id
- $index[‘body’] = array(
- ‘mac’ => 'fcd5d900beca',
- ‘customer_id’ => 3,
- ‘product_id’ => 5,
- ‘version’ => 2
- );
- $elastic->index($index);
查询
- include('./vendor/autoload.php');
- $elastic = new Elasticsearch\Client();
- $index[‘index’] = ‘log’; //索引名称
- $index[‘type’] = ‘ems_run_log’; //类型名称
- $index[‘body’][‘query’][‘bool’][‘must’] = array(
- array(‘match’ => array(‘mac’ => ‘fcd5d900beca’)),
- array(‘match’ => array(‘product_id’ => 20))
- );
- $index[‘size’] = 10;
- $index[‘from’] = 200;
- $elastic->search($index);
- 相当于sql语句：
- select*from ems_run_log where mac=‘fcd5d900beca’
- and product_id = 20 limit 200,10;
删除文档
- <pre name="code" class="php">include('./vendor/autoload.php');
- $elastic = new Elasticsearch\Client();
- $index['index'] = 'test'; //索引名称
- $index['type'] = 'ems_test'; //类型名称
- $index['id'] = 2;
- $elastic->delete($index);
