使用elasticdump迁移数据时遇MOVED_PERMANENTLY错误求助

问题原因： #

Elasticsearch返回了301永久重定向响应，而elasticdump默认不会自动跟随重定向，导致后续请求失败，迁移中断。

解决方案： #

• 替换源地址为正确的重定向目标URI：确认Elasticsearch集群的实际访问地址，将elasticdump命令中--input参数的旧地址替换为新的URI。
• 启用重定向跟随：如果使用的elasticdump版本支持，添加--followRedirects true参数，示例命令：

  elasticdump --input http://old-es-address:9200/target-index --output ./data-dump.json --followRedirects true
  

• 检查前端代理配置：若Elasticsearch前部署了反向代理（如Nginx），确认代理规则没有返回不必要的重定向，同时确保请求地址与代理配置的域名/IP完全匹配。
