## 为什么导入集群时,提示“权限不足”?

导入集群的时候,需要访问服务安装的路径。如果操作服务的账号没有访问权限的话,无法成功导入集群。用户可授予操作账号访问服务的权限,然后使用操作账号重启服务。

## 为什么导入集群时,提示 “ssh 连接失败”?

如果在为节点授权时,**节点Host** 显示为`127.0.0.1`且 Dashboard 和 Nebula Graph 没有被部署在同一台机器上,系统会提示 “ssh 连接失败”。用户需要在 Nebula Graph 所有服务的配置文件中,修改各服务的 Host IP 为真实的机器 IP。更多信息,参见[配置管理](../5.configurations-and-logs/1.configurations/1.configurations.md)。

如果用户导入的是 Docker 部署的集群,也会显示 “ssh 连接失败”。Dashboard 不支持导入使用 Docker 部署的集群。
