curl -XGET 'http://10.45.186.155:9200/_cat/indices?pretty'

4、创建索引
curl -XPUT  'http://10.45.186.155:9200/gwtest01?pretty'  -H 'Content-Type: application/json' -d '
{
"settings": {
"number_of_shards": "36",
"number_of_replicas": "0"
}
}'

5、给索引添加一条数据
curl -XPOST 'http://10.45.186.155:9200/gwtest01/stu/1?pretty' -H 'Content-Type: application/json' -d '

[elastic@gwtest156 0]$  curl -XGET 'http://10.45.186.156:9200/gwtest02/_settings?pretty'
{
  "gwtest02" : {
    "settings" : {

        "creation_date" : "1634645232394",
        "number_of_shards" : "5",        #主分片数，默认为5，只能在建索引时设置，不能修改
        "number_of_replicas" : "1",     #设置索引分片副本数，默认为1，可以随时修改
        "uuid" : "98xWMOHKQUaP1Rl90p7zQA",
        "version" : {
          "created" : "6030099"
        },
        "provided_name" : "gwtest02"

{
  "gwtest02" : {
    "mappings" : {
      "stu" : {
        "properties" : {
          "age" : {
            "type" : "long"
