创建集群对等关系
可以使用 cluster peer create 命令来创建本地和远程集群之间的对等关系。创建对等关系之后,可以在远程集群上运行 cluster peer create 以将其认证到本地集群。
必须在正在建立对等关系的集群中的每个节点上创建集群间 LIF。
- 在目标集群上,创建与源集群之间的对等关系:cluster peer create -generate-passphrase -offer-expiration MM/DD/YYYY HH:MM:SS|1...7days|1...168hours -peer-addrs peer_LIF_IPs -ipspace ipspace 如果同时指定 -generate-passphrase 和 -peer-addrs,只有在 -peer-addrs 中指定了集群间 LIF 的集群才可以使用生成的密码。
如果没有使用自定义 Ipspace,可以忽略 -ipspace 选项。有关完整的命令语法,请参阅手册页。
以下示例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. - 在源集群上,向目标集群认证源集群:cluster peer create -peer-addrs peer_LIF_IPs -ipspace ipspace 有关完整的命令语法,请参阅手册页。
以下示例将在集群间 LIF IP 地址为 192.140.112.101 和 192.140.112.102 的远程集群上完成本地集群认证:
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.出现系统提示时,输入对等关系的密码短语。 - 验证是否已创建集群对等关系:cluster peer show -instance
cluster01::> cluster peer show -instance
