近期部署elasticsearch后，启动时发现一直报如下错误:
curl: (7) Failed connect to localhost:9200； Connection refused部署的版本为elasticsearch-7.13.2,排查原因是因为开启了ssl认证。
解决方法:
在/opt/software/elasticsearch-7.13.2/config下修改elasticsearch.yml配置,添加如下内容:
xpack.security.http.ssl.enabled: false日志报错2如下:文章来源：https://www.toymoban.com/news/detail-743238.html
