1，查看集群节点信息
集群的任意节点上都可以查询的 （master、date）
curl -XGET http://10.4.7.11:9200/_nodes/process?pretty
2，查询集群的健康状态
curl http://10.4.7.11:9200/_cluster/health?pretty
curl http://10.4.7.11:9200/_cluster/health/'新蔡'?pretty
3，查看集群节点属性
curl http://10.4.7.11:9200/_cat/
=^.^=
/_cat/allocation
/_cat/shards
/_cat/shards/{index}
/_cat/master
/_cat/nodes
/_cat/tasks
/_cat/indices
/_cat/indices/{index}
/_cat/segments
/_cat/segments/{index}
/_cat/count
/_cat/count/{index}
/_cat/recovery
/_cat/recovery/{index}
/_cat/health
/_cat/pending_tasks
/_cat/aliases

/_cat/ml/datafeeds/{datafeed_id}
/_cat/ml/data_frame/analytics
/_cat/ml/data_frame/analytics/{id}
/_cat/transforms
/_cat/transforms/{transform_id}
4，查看集群索引
curl http://10.4.7.11:9200/_cat/shards
curl http://10.4.7.11:9200/_cat/shards|grep -n '新蔡'
索引模板
1，用curl创建一个索引模板
curl -H "Content-Type: application/json" -DPUT 'http://10.4.7.11:9200/_template/filebeat' -d '{
"template": "filebeat*",
"settings": {
"number_of_shards": 5,
"number_of_replicas": "2"
}
}'
2，查看索引模板
a，用火狐浏览器查看
http://10.4.7.11:9200/_template/filebeat
b，用curl查看
curl -XGET http://10.4.7.11:9200/_template/filebeat
{"acknowledged":true}
