First, index operation

Curl-XPUT http://127.0.0.1:9200/xrf_test_index001-d'{"setting": {"index": {"number_of_shards": 5, "number_of_replication": 1}}'# create a manually specified shard copy

Curl-XPOST http://127.0.0.1:9200/xrf_test_index001/_close # turn off the index

Curl-XPOST http://127.0.0.1:9200/xrf_test_index001/_open # Open the index

Curl-XDELETE http://127.0.0.1:9200/xrf_test_index001 # delete index

Curl-XPUT http://127.0.0.1:9200/xrf_test_index001/_settings-d'{"index": {"number_of_replicas": 1}}'# adjust the number of copies

Curl-XPOST http://127.0.0.1:9200/_aliases-d'{"actions": [{"add": {"index": "xrf_test_index001", "alias": "xrf_test"}}]}'# add index aliases

Curl-XPOST http://127.0.0.1:9200/_aliases-d'{"actions": [{"remove": {"index": "xrf_test_index001", "alias": "xrf_test"}}]}'# Delete aliases

Second, slicing operation

Curl-XPUT http://127.0.0.1:9200/_cluster/settings-d'{"transient": {"cluster.routing.allocation.enable": "none"}'# turn off automatic sharding persistent means permanent

Curl-XPUT http://127.0.0.1:9200/_cluster/settings-d'{"transient": {"cluster.routing.allocation.enable": "all"}'# starts automatic slicing

Curl-XPUT http://127.0.0.1:9200/_cluster/settings-d'{"transient": {"cluster.routing.allocation.cluster_concurrent_rebalance": 5}}'# set the number of sharded balanced threads

Curl-XPUT http://127.0.0.1:9200/_cluster/settings-d'{"transient": {"cluster.routing.allocation.exclude._ip": "1.1.1.1"}}'# excluding machines or nodes, shards on the changed nodes will be adjusted to other nodes, and _ name,_hostname,_ip is supported

Third, node operation

Curl-XPOST http://127.0.0.1:9200/_cluster/nodes/_local/_shutdown?delay=10s # delays shutting down native nodes for 10s, invalid kill $pid after 2.x

Curl-XPOST http://127.0.0.1:9200/_cluster/nodes/nodeId1,nodeId2/_shutdown # shuts down node nodeId1,nodeId2

Curl-XPOST http://127.0.0.1:9200/_cluster/nodes/_master/_shutdown # shuts down the primary node

Fourth, status check

Curl-XGET http://127.0.0.1:9200/_cluster/nodes # gets the list and information of nodes in the cluster

Curl-XGET http://127.0.0.1:9200/_cluster/health # to get cluster information

Curl-XGET http://127.0.0.1:9200/_cluster/state # gets all the information in the cluster (cluster information, node information, mapping information, etc.)

Curl-XGET http://127.0.0.1:9200/_cat/nodes # View the list of cluster nodes

Curl-XGET http://127.0.0.1:9200/_cat/indices # View cluster index list

Curl-XGET http://127.0.0.1:9200/_cat/shards # View the list of cluster shards
