复制集群状态

您可以通过检查节点状态来查看集群状态信息。这可以使用 节点状态 命令完成，该命令显示有关节点的各种信息，包括集群状态变量。

集群状态变量的输出格式如下：cluster_name_variable_name variable_value。大多数变量在 Galera 文档状态变量 中有描述。除了这些变量，Manticore Search 还显示：

• cluster_name - 集群的名称，如在 复制设置 中定义

• node_state - 节点的当前状态：closed、destroyed、joining、donor、synced

• indexes_count - 集群管理的表的数量

• indexes - 集群管理的表名称列表

• nodes_set - 使用 CREATE、JOIN 或 ALTER UPDATE 命令定义的集群中的节点列表

• nodes_view - 当前节点可以看到的集群中实际的节点列表
