首先

为了输入样本数据，故意安装了旧版本的Magento，但V2.3.5中的搜索引擎是MySql。现在将其更改为ElasticSearch。

编辑/etc/elasticsearch/elasticsearch.yml文件

然后，将重新启动elasticsearch。顺便提一下，elasticsearch的日志位于/var/log/elasticsearch/目录下。

sudo systemctl daemon-reload
sudo systemctl restart elasticsearch.service

修改Magento的设置

引擎的设置位于商店 – 配置 – 目录 – 目录搜索中。

取消“使用系统值”选项，选择Elasticsearch。

我們將使用此按鈕進行連接測試。

只要出现以下显示，连接确认OK。

保存配置。

由于只有这个命令，不会有任何输出，所以重新创建缓存和索引。
