Basic commands

Information about the cluster CLUSTER info print cluster CLUSTER NODES lists all nodes currently known to the cluster, as well as information about those nodes.  Node CLUSTER MEET <ip> <port> adds the node specified by IP and port to the cluster, making it part of the cluster.  CLUSTER Forget <node_id> removes node_id specified node from the cluster.  CLUSTER REPLICATE <node_id> Sets the current node to node_id node from the specified node.  CLUSTER Saveconfig Save the configuration file of the node to the hard disk.  Slot (slot) CLUSTER addslots <slot> [slots ...] assigns one or more slots (slots) (assign) to the current node.  CLUSTER delslots <slot> [slots ...] removes the assignment of one or more slots to the current node.  CLUSTER Flushslots removes all slots assigned to the current node, making the current node a node without any slots assigned.  CLUSTER setslot <slot> Node <node_id> assigns the slot slot to the node specified by node_id, and if the slot is already assigned to another node, let the other node delete the slot before assigning it.  CLUSTER setslot <slot> Migrating <node_id> migrates the slot slots of this node to the nodes specified in the node_id.  CLUSTER setslot <slot> importing <node_id> import slot slots from node_id specified node to this node.  CLUSTER Setslot <slot> STABLE cancels the import or migration (migrate) of the slot slots.  Key CLUSTER keyslot <key> calculate the key should be placed on which slot.  CLUSTER Countkeysinslot <slot> Returns the number of key-value pairs currently contained in the slot slot. CLUSTER GetkeysinslOT <slot> <count> returns the key in count slot slots.
