您可以使用 cluster peer create 命令在本地和远程集群之间创建对等关系。创建对等关系后,您可以在远程集群上运行 cluster peer create,以便向本地集群验证其身份。
如果未使用自定义 IP 空间,则可以忽略 -ipspace 选项。有关完整的命令语法,请参见手册页。
以下示例将在未指定的远程集群上创建集群对等关系:
cluster02::> cluster peer create -generate-passphrase -offer-expiration 2days Passphrase: UCa+6lRVICXeL/gq1WrK7ShR Expiration Time: 6/7/2017 08:16:10 EST Initial Allowed Vserver Peers: - Intercluster LIF IP: 192.140.112.101 Peer Cluster Name: Clus_7ShR (temporary generated) Warning: make a note of the passphrase - it cannot be displayed again.
cluster01::> cluster peer create -peer-addrs 192.140.112.101,192.140.112.102 Notice: Use a generated passphrase or choose a passphrase of 8 or more characters. To ensure the authenticity of the peering relationship, use a phrase or sequence of characters that would be hard to guess. Enter the passphrase: Confirm the passphrase: Clusters cluster02 and cluster01 are peered.
