【问题描述】：

尝试在 magento 2.4 中搜索产品时返回以下错误

异常 #0 (Elasticsearch\Common\Exceptions\NoNodesAvailableException)：在您的集群中找不到活动节点

以下配置：

PHP 7.4.1
Nginx 1.14
MySql 8
弹性搜索 7.9

/etc/nginx/conf.d/100-magento2.conf

upstream fastcgi_backend {
    server   unix:/run/php-fpm/www.sock;
}
server {
  listen 80;
  server_name _;

  set $MAGE_ROOT /var/www/magento2;
  include /var/www/magento2/nginx.conf.sample;

}

/etc/nginx/conf.d/90-es.conf

upstream   elasticsearch {
   server 127.0.0.1:9200;
}


server {
   server_name _;
   listen 8080;
   location / {
     limit_except HEAD {
        auth_basic "Restricted";
        auth_basic_user_file  /etc/nginx/passwd/.esnginx;
     }
     proxy_pass http://127.0.0.1:9200;
     proxy_redirect off;
     proxy_set_header Host $host;
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }

  location /_aliases {
   auth_basic "Restricted";
   auth_basic_user_file  /etc/nginx/passwd/.esnginx;
   proxy_pass http://127.0.0.1:9200;
   proxy_redirect off;
   proxy_set_header Host $host;
   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }

  include /etc/nginx/auth/*.conf;
}

如果尝试：bin/magento config:show catalog/search/engine

结果：elasticsearch7

如果尝试： curl -i localhost:9200/_cluster/health?pretty

HTTP/1.1 200 OK

如果在网络上尝试：
Configuration by web

elasticsearch.yml： elasticsearch.yml

【问题讨论】：

问题是selinux，已解决

标签： elasticsearch nginx magento2 nginx-config proxypass

【解决方案1】：

我遇到了完全相同的问题。对我来说，这是与 Smile-SA /elasticsuite 的兼容性问题。

解决方法是删除“vendor/smile”文件夹，然后执行composer dump-autoload。（我知道这不是永久修复，我现在拥有的）
