Laravel：Elasticsearch\Common\Exceptions\NoNodesAvailableException

Question

我正在尝试在 Laravel 应用程序中运行 Elasticsearch。 我在本地主机上运行http://127.0.0.1:8000

我的 elasticsearch 已成功启动，所有安装均已成功完成..尽管仍然出现错误：

No alive nodes found in your cluster

在 .env 文件中：

ELASTICSEARCH_HOST=localhost
ELASTICSEARCH_PORT=9200
ELASTICSEARCH_SCHEME=http
ELASTICSEARCH_CORE_SUFFIX=dev2

我的 app.php 的一部分：

已安装的应用程序：

"require": {
        "php": ">=7.1.19",
        "cviebrock/laravel-elasticsearch": "^2",
        "fideloper/proxy": "~3.3",

        "spatie/calendar-links": "^1.0",
        "webpatser/laravel-countries": "dev-master#33767373"
    },

当我运行brew services restart elasticsearch

我明白了：

 Successfully started `elasticsearch` (label: homebrew.mxcl.elasticsearch)

Answer 1

您是否在 .env 中定义了弹性节点/主机？这也在运行吗？

curl -X GET http://localhost:9200/ 

Answer 2

我通过终端运行 ES 解决了这个问题
