mac启动elasticsearch

在Mac上启动Elasticsearch，你需要遵循以下步骤：

1. 确保你已经安装了Java Development Kit (JDK)。Elasticsearch 7.x及以上版本需要Java 11或更高版本。可以使用java -version命令来检查Java版本。
2. 下载并解压Elasticsearch。你可以从Elasticsearch官方网站下载相应的版本。
3. 打开终端（Terminal）。

4. 导航到Elasticsearch的根目录。例如，如果Elasticsearch解压在~/Downloads/elasticsearch-7.10.0，你应该执行以下命令：

   
   
   
   cd ~/Downloads/elasticsearch-7.10.0

5. 运行Elasticsearch。在Elasticsearch根目录下，执行以下命令：

   
   
   
   ./bin/elasticsearch

如果Elasticsearch正常启动，你将看到类似以下的输出：

Elasticsearch现在应该正在运行。你可以通过访问http://localhost:9200来验证它是否正常工作。如果你看到一个JSON响应，表明Elasticsearch正在正常运行。
