使用中的es突然挂了，在启动就错
Authentication of [elastic] was terminated by realm [reserved] - failed to authenticate user [elastic]
无法启动了，怎么解决？比较急

***重点生成新的证书
***重点生成新的证书
问题处理流程：
1. 停止es
2. xpack取消
3. 启动，以无密码形式登录
4. 删除.security
5. 停es
6. xpack开启
7. 删除elasticsearch/config目录下elasticsearch.keystore、elastic-certificates.p12
8. bin目录下执行
./elasticsearch-certutil cert -out config/elastic-certificates.p12 -pass ""
如果是集群，需要把config/elastic-certificates.p12拷贝到其他节点的config目录下
9. es节点依次启动
10. 设置密码,等待cluster health is currently RED.变为green在下一步
