一、准备
-
本次使用 xxx 的一套ES集群做展示。
-
不区分es版本
-

二、操作
-
查看集群实际主的IP和hostname
curl --user elastic:P6UbYWOSj7Xx http://172.25.178.236:9200/_cat/nodes?v
-
查看策略
-
将节点 master oh-enhancement-63 剔除候选主清单
curl -X POST --user elastic:P6UbYWOSj7Xx http://172.25.178.237:9200/_cluster/voting_config_exclusions?node_names=oh-enhancement-63
-
查看修改后的策略
curl -X GET --user elastic:P6UbYWOSj7Xx http://172.25.178.237:9200/_cluster/state?filter_path=metadata.cluster_coordination.voting_config_exclusions
-
如果配置错误，清除策略，没有错误的话跳过此步骤
curl -X DELETE --user elastic:P6UbYWOSj7Xx http://172.25.178.237:9200/_cluster/voting_config_exclusions?wait_for_removal=false
-
完成
三、注意
- node_names 参数为node ID，也就是说为hostname
- voting_config_exclusions 参数同时设置多个node ID的时候使用 逗号 分割
curl -X POST http://172.16.70.34:9200/_cluster/voting_config_exclusions?node_names=ec-master-node-13,ec-master-node-14,ec-master-node-12
