无法在Elasticsearch中创建索引

Question

我是Elasticsearch的新手，所以我知道我忘记了一些东西，但不知道是什么。

我运行了这段代码：

error_reporting(E_ALL);
ini_set('display_errors', 1);

require 'vendor/autoload.php';

use Elasticsearch\ClientBuilder;

$client = ClientBuilder::create()->build();
$params = [
  'index' => 'my_index'
];

// Create the index
$response = $client->indices()->create($params);

但是出现此错误：

{
  "error": {
    "root_cause": [
      {
        "type":"index_not_found_exception",
        "reason":"no such index",
        "resource.type":"index_or_alias",
        "resource.id":"elasticsearch-i.php",
        "index_uuid":"_na_",
        "index":"elasticsearch-i.php"
      }
    ],
    "type":"index_not_found_exception",
    "reason":"no such index",
    "resource.type":"index_or_alias",
    "resource.id":"elasticsearch-i.php",
    "index_uuid":"_na_",
    "index":"elasticsearch-i.php"
  },
  "status":404
}

Answer 1

我尚未在Elasticsearch服务器本身上创建索引。

我必须先创建它，然后才能在php-api上访问它

为此，我运行：

curl -X PUT -x  "" "http://127.0.0.1:9200"/test

在命令提示符下

Answer 2

有几个原因不保存索引。首先检查您的Elasticsearch集群状态，然后尝试从任何客户端创建索引。

检查Elasticsearch的状态

集群的运行状况或状态

curl -X GET "localhost:9200/_cluster/health"

OR

curl -X GET "localhost:9200/_cluster/state"

OR

curl -X GET "localhost:9200/_nodes/stats"

使用curl

创建索引

curl -X PUT "localhost:9200/twitter"

这是使用php创建的简单代码：

$client = ClientBuilder::create()->build();
$params = [
    'index' => 'twitter_2'
];

$response = $client->indices()->create($params);
