ClearPass 6.8以上版本Cluster集群配置证书信任问题


从ClearPass 6.8开始,建立集群和删除集群时增加了对Publisher和Subscriber HTTPs证书的校验。当Subscriber添加到Publisher时Subscriber会校验Publisher的HTTPs证书是否被信任,当在Publisher上删除Subscriber时,Publisher会校验Subscriber的HTTPs证书是否被信任,当证书校验不通过时会提示WARNING – 10.X.50.41: echo GET failed. 并且无法成功创建集群或者删除集群。



[appadmin@Lab5-CPPM-1]# cluster make-subscriber -V -i 10.X.50.41

2、分别在Publisher和Subscriber上创建证书签名请求CSR,通过CA(这里采用ClearPass Onboard)签发HTTPs证书,分别在Publisher和Subscriber上导入HTTPs证书,并在证书信任列表中导入对方的证书链。推荐采用此方式。

通过ClearPass Onboard给Publisher节点签发HTTPs证书具体流程,参考以下文档:
