1、删除对应的es 节点
$head = ‘Content-Type: application/json‘; $json = ‘‘; $res = Curl_es("http://127.0.0.1:9200/my_index_2?pretty",‘DELETE‘,$json,$head); function Curl_es($url, $method, $data_string, $head) { $ch = curl_init($url); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method); curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HTTPHEADER, array($head)); $result = curl_exec($ch); if (curl_errno($ch)) { print curl_error($ch); } curl_close($ch); return $result; }
2、retrying failed action with response code: 403 ({"type"=>"cluster_block_exception", "reason"=>"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)]
这是由于ES新节点的数据目录data存储空间不足,导致从master主节点接收同步数据的时候失败,此时ES集群为了保护数据,会自动把索引分片index置为只读read-only
$head = ‘Content-Type: application/json‘; $json = ‘{ "index":{ "blocks":{ "read_only_allow_delete":"false" } }}‘; $res = Curl_es("http://10.10.1.136:9200/_settings?pretty", ‘PUT‘, $json, $head);
3、es设置index.max_result_window(就是from+size,默认大小10000),可通过如下方式修改:
$head = ‘Content-Type: application/json‘; $json = ‘{ "index":{ "max_result_window": 10000000 }}‘; $res = Curl_es("http://10.10.1.136:9200/_settings?pretty", ‘PUT‘, $json, $head); echo $res;
