Laravel scout 弹性搜索错误 500 "all shards failed"

Question

每当我尝试通过 Laravel 的 scout 包使用 Elasticsearch 时，我都会收到此错误。

一切都在我的本地主机上运行，因为我不必为弹性搜索设置任何节点或任何东西，但是当我尝试在我的远程服务器上做同样的事情时，这就是我得到的。

}

这是我检索结果的方式

    public function search(Request $request)
    {
        $products = Product::search($request->get('label'))->get();

        return response()->json($products);
    }

我通过 php artisan scout:import 'App\Models\Products' 导入了产品的 table 数据，它给了我一条成功消息。所以一切似乎都是正确的。

GET /_cluster/allocation/explain?pretty给我

{
  "index": "products",
  "shard": 0,
  "primary": false,
  "current_state": "unassigned",
  "unassigned_info": {
    "reason": "INDEX_CREATED",
    "at": "2020-11-07T17:32:11.894Z",
    "last_allocation_status": "no_attempt"
  },
  "can_allocate": "no",
  "allocate_explanation": "cannot allocate because allocation is not permitted to any of the nodes"
}

而“GET /_cluster/health?pretty”给了我

{
  "cluster_name": "myCluster",
  "status": "red",
  "timed_out": false,
  "number_of_nodes": 1,
  "number_of_data_nodes": 0,
  "active_primary_shards": 0,
  "active_shards": 0,
  "relocating_shards": 0,
  "initializing_shards": 0,
  "unassigned_shards": 2,
  "delayed_unassigned_shards": 0,
  "number_of_pending_tasks": 0,
  "number_of_in_flight_fetch": 0,
  "task_max_waiting_in_queue_millis": 0,
  "active_shards_percent_as_number": 0.0
}

在 windows 上一切正常，因为我需要做的就是 .\bin\elasticsearch.bat，但 Centos 让我很头疼。

Answer 1

/_cluster/health的结果表明你的单节点没有配置为数据节点。

"number_of_data_nodes": 0,

查看中的配置，您有 node.roles: [master]，因此这使您的节点仅作为 master 节点工作，要摄取数据，您需要一个具有角色 data.

由于您只有一个节点，因此没有理由设置 node.roles 选项。

注释掉这一行并重启elasticsearch，它会执行一个节点可以做的所有roles。

您也可以根据需要设置为 master 和 data 节点。

node.roles: [master, data]
