php: 操作elasticsearch的別名

一，新增別名

1，程式碼：

        //初始化es的client
        $client = $this->_init_es();

        // 確定引數
        $params = [
            'index' => 'gs_second',      //索引名字
            'name' => 'gs_second_idx',   //索引的別名
        ];

        // 執行
        //$client = EsHelper::getEsClient();
        try {
            $response = $client->indices()->putAlias($params);
            $result = $response->asArray();
            echo "響應:<br/>";
            if ($result['acknowledged'] == true) {
                echo "別名建立成功";
            } else {
                echo "別名建立失敗";
            }
            var_dump($result);
        }catch (\Exception $e){
            $result = $e->getMessage();
            echo "異常:<br/>";
            var_dump($result);
        }

2，測試效果:

新增前:

liuhongdi@lhdpc:~$ curl  -sXGET localhost:9200/_cat/aliases?v
alias         index     filter routing.index routing.search is_write_index
gs_second_idx gs_second -      -             -              -

新增後:

liuhongdi@lhdpc:~$ curl  -sXGET localhost:9200/_cat/aliases?v
alias         index     filter routing.index routing.search is_write_index
gs_second_idx gs_second -      -             -              -

二，刪除別名

1,程式碼:

        //初始化es的client
        $client = $this->_init_es();


        // 確定引數
        $params = [
            'index' => 'gs_second',      //索引名字
            'name' => 'gs_second_idx',   //索引的別名
        ];

        // 執行
        //$client = EsHelper::getEsClient();
        try {
            $response = $client->indices()->deleteAlias($params);
            $result = $response->asArray();
            echo "響應:<br/>";
            if ($result['acknowledged'] == true) {
                echo "別名刪除成功";
            } else {
                echo "別名刪除失敗";
            }
            var_dump($result);
        }catch (\Exception $e){
            $result = $e->getMessage();
            echo "異常:<br/>";
            var_dump($result);
        }

2，測試效果:

刪除前:

liuhongdi@lhdpc:~$ curl  -sXGET localhost:9200/_cat/aliases?v
alias         index     filter routing.index routing.search is_write_index
gs_second_idx gs_second -      -             -              -

刪除後:

liuhongdi@lhdpc:~$ curl  -sXGET localhost:9200/_cat/aliases?v
alias index filter routing.index routing.search is_write_index

三，根據別名得到索引名

1,程式碼:

$params = [
            'name'=>'gs_second_idx',   //要查詢的別名 
        ];
        try {
            $response = $client->indices()->getAlias($params);
            $result = $response->asArray();
            var_dump($result);
        }catch (\Exception $e){
            $result = $e->getMessage();
        }

2,測試效果:

array(1) { ["gs_second"]=> array(1) { ["aliases"]=> array(1) { ["gs_second_idx"]=> array(0) { } } } }

四，根據索引名得到別名

1,程式碼:

        $params = [
            'index'=>'gs_second',
        ];
        try {
            $response = $client->indices()->getAlias($params);
            $result = $response->asArray();
            var_dump($result);
        }catch (\Exception $e){
            $result = $e->getMessage();
        }

2，測試效果:

array(1) { ["gs_second"]=> array(1) { ["aliases"]=> array(1) { ["gs_second_idx"]=> array(0) { } } } }

說明：getAlias()方法不加引數則得到列出所有索引的別名
