安装

curl -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.6.0-darwin-x86_64.tar.gz
curl https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.6.0-darwin-x86_64.tar.gz.sha512 | shasum -a 512 -c - 
tar -xzf elasticsearch-8.6.0-darwin-x86_64.tar.gz
cd elasticsearch-8.6.0/

初次启动，会有如下提示，密码等信息

✅ Elasticsearch security features have been automatically configured!
✅ Authentication is enabled and cluster connections are encrypted.

ℹ️  Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):
  BYH5mquiw3poy1*ywrU=

ℹ️  HTTP CA certificate SHA-256 fingerprint:
  82080351feb2e4397db2cbfad71730aee5a4605d8583fcf577e5c1c65755caaf

ℹ️  Configure Kibana to use this cluster:
• Run Kibana and click the configuration link in the terminal when Kibana starts.
• Copy the following enrollment token and paste it into Kibana in your browser (valid for the next 30 minutes):
  eyJ2ZXIiOiI4LjYuMCIsImFkciI6WyIxOTIuMTY4LjEuMTUyOjkyMDAiXSwiZmdyIjoiODIwODAzNTFmZWIyZTQzOTdkYjJjYmZhZDcxNzMwYWVlNWE0NjA1ZDg1ODNmY2Y1NzdlNWMxYzY1NzU1Y2FhZiIsImtleSI6Ilp6X0F3NFVCU0p0V3dJUkpWZWF4OnEwaU1xc25LU0VxTlFZTldLbzNsTHcifQ==

ℹ️  Configure other nodes to join this cluster:
• On this node:
  ⁃ Create an enrollment token with `bin/elasticsearch-create-enrollment-token -s node`.
  ⁃ Uncomment the transport.host setting at the end of config/elasticsearch.yml.
  ⁃ Restart Elasticsearch.
• On other nodes:
  ⁃ Start Elasticsearch with `bin/elasticsearch --enrollment-token <token>`, using the enrollment token that you generated.

正则查询

es的正则查询和平时我们使用的正则稍有区别，需要根据官方文档说明来写正则。比如，我们正则匹配一个包含数字和英文的：

(base) ➜  elasticsearch-8.6.0 curl -X GET --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:BYH5mquiw3poy1*ywrU=" "https://localhost:9200/split_file/_search?pretty" -H 'Content-Type: application/json' -d'
{
      "query": {
          "regexp": {
              "predict_value": "<0-1000000000>[a-z]{0,4}" 
          }
      }
  }
'
{
  "took" : 24,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 1,
      "relation" : "eq"
    },
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "split_file",
        "_id" : "JOjuw4UBPd4SWO866Je4",
        "_score" : 1.0,
        "_source" : {
          "uuid" : "6d20a8ba-9706-11ed-8f3b-acde48001122",
          "filename" : "Text_343.jpg",
          "path" : "data/split_file/og_file/huaxintest/ce91c1fc9c5ca0daf6eeca65cfef6861_758ca3e7ec50b24aeb1531df7f278e6c.jpg",
          "time_stamp" : "2022-05-19 14:15:25.255753",
          "marked_status" : 1,
          "quality_status" : 1,
          "app_id" : 2,
          "user_id" : 1,
          "data_type" : 1,
          "dataset_id" : 5,
          "marked_file_path" : "data/split_file/marked_file/huaxintest/ce91c1fc9c5ca0daf6eeca65cfef6861_758ca3e7ec50b24aeb1531df7f278e6c.json",
          "predict_value" : "456test"
        }
      }
    ]
  }
}
