# 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](/manticoresearch-manual-zh/jie-dian-xin-xi-yu-guan-li/node_status.md) 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](https://galeracluster.com/library/documentation/galera-status-variables.html) 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](/manticoresearch-manual-zh/creating_a_cluster/setting_up_replication.md#Replication-cluster) 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 **SQL:** ```sql SHOW STATUS ``` ```sql +----------------------------+-------------------------------------------------------------------------------------+ | Counter | Value | +----------------------------+-------------------------------------------------------------------------------------+ | cluster_name | post | | cluster_post_state_uuid | fba97c45-36df-11e9-a84e-eb09d14b8ea7 | | cluster_post_conf_id | 1 | | cluster_post_status | primary | | cluster_post_size | 5 | | cluster_post_local_index | 0 | | cluster_post_node_state | synced | | cluster_post_indexes_count | 2 | | cluster_post_indexes | pq1,pq_posts | | cluster_post_nodes_set | 10.10.0.1:9312 | | cluster_post_nodes_view | 10.10.0.1:9312,10.10.0.1:9320:replication,10.10.1.1:9312,10.10.1.1:9320:replication | ``` ```json POST /cli -d " SHOW STATUS " ``` ```json " {"columns":[{"Counter":{"type":"string"}},{"Value":{"type":"string"}}], "data":[ {"Counter":"cluster_name", "Value":"post"}, {"Counter":"cluster_post_state_uuid", "Value":"fba97c45-36df-11e9-a84e-eb09d14b8ea7"}, {"Counter":"cluster_post_conf_id", "Value":"1"}, {"Counter":"cluster_post_status", "Value":"primary"}, {"Counter":"cluster_post_size", "Value":"5"}, {"Counter":"cluster_post_local_index", "Value":"0"}, {"Counter":"cluster_post_node_state", "Value":"synced"}, {"Counter":"cluster_post_indexes_count", "Value":"2"}, {"Counter":"cluster_post_indexes", "Value":"pq1,pq_posts"}, {"Counter":"cluster_post_nodes_set", "Value":"10.10.0.1:9312"}, {"Counter":"cluster_post_nodes_view", "Value":"10.10.0.1:9312,10.10.0.1:9320:replication,10.10.1.1:9312,10.10.1.1:9320:replication"} ], "total":0, "error":"", "warning":"" } ``` ```php $params = [ 'body' => [] ];

Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://vergil-lai.gitbook.io/manticoresearch-manual-zh/creating_a_cluster/setting_up_replication/replication_cluster_status.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
