您可以使用证书通过 hub 集群验证受管集群。因此，了解与这些证书关联的故障排除方案非常重要。

受管集群证书会自动刷新。

您可以刷新 Red Hat Advanced Cluster Management 受管证书，它们是由 Red Hat Advanced Cluster Management 服务创建和管理的证书。

完成以下步骤以刷新 Red Hat Advanced Cluster Management 管理的证书：

如果您不想使用 OpenShift 默认入口证书，请通过更新 alertmanager 路由来替换 observability alertmanager 证书。完成以下步骤：

完成以下步骤以轮转 gatekeeper Webhook 证书：

gatekeeper Webhook 证书被轮转。

按照以下流程验证您的证书是否已轮转：

您可以查看在内部使用 OpenShift Service Serving 证书服务的 hub 集群受管证书列表。运行以下命令列出证书：

for ns in multicluster-engine open-cluster-management ; do echo "$ns:" ; oc get secret -n $ns -o custom-columns=Name:.metadata.name,Expiration:.metadata.annotations.service\\.beta\\.openshift\\.io/expiry | grep -v '<none>' ; echo ""; done

如需更多信息，请参阅附加资源部分中的 OpenShift Service Serving 证书部分。

注：如果启用了可观察性，则还需要额外的命名空间来创建证书。
