系统版本：Centos7
elk 版本：6.8.0
目前集群情况 master 3台 data 100 台  client 20台
集群为生产环境有数据
请给出建议帮助排查问题
步骤
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: /home/elk/elasticsearch/config/certs/elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: /home/elk/elasticsearch/config/certs/elastic-certificates.p12
 
复制elastic-certificates.p12 至所有节点。master data 节点
使用如下进行解密
./elasticsearch-keystore add xpack.security.transport.ssl.keystore.secure_password
./elasticsearch-keystore add xpack.security.transport.ssl.truststore.secure_password
日志中可以看到可以组件集群
在进行./elasticsearch-setup-passwords interactive --verbose
出现如下截图情况
在进行x-pack 加密时出现
