ElasticSearch之安装

参照Installing Elasticsearch，完成验证集群的部署。

操作步骤

• 下载软件包和摘要文件。

  wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.11.1-linux-x86_64.tar.gz
  wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.11.1-linux-x86_64.tar.gz.sha512
  

• 校验压缩包的完整性。

  shasum -a 512 -c elasticsearch-8.11.1-linux-x86_64.tar.gz.sha512
  

• 解压软件包。

  tar -xzf elasticsearch-8.11.1-linux-x86_64.tar.gz
  

• 启动elasticsearch服务。

  cd elasticsearch-8.11.1/
  export ELASTIC_PASSWORD="espass"
  ./bin/elasticsearch
  

• 修改口令。注意需要新开一个shell命令行窗口。

  ./bin/elasticsearch-reset-password -u elastic
  

  命令的输出如下：

  This tool will reset the password of the [elastic] user to an autogenerated value.
  The password will be printed in the console.
  Please confirm that you would like to continue [y/N]y
  
  
  Password for the [elastic] user successfully reset.
  New value: ohCxPH=QBE+s5=*lo7F9
  

  得到新的口令为ohCxPH=QBE+s5=*lo7F9。

• 检查服务是否可用。

  export ES_HOME=~/elasticsearch-8.11.1
  curl --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9" https://localhost:9200
  

  输出如下：

  {
  "name" : "jackie-ubuntu",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "BH48zgLGR9S0mjjShrpyFA",
  "version" : {
      "number" : "8.11.1",
      "build_flavor" : "default",
      "build_type" : "tar",
      "build_hash" : "6f9ff581fbcde658e6f69d6ce03050f060d1fd0c",
      "build_date" : "2023-11-11T10:05:59.421038163Z",
      "build_snapshot" : false,
      "lucene_version" : "9.8.0",
      "minimum_wire_compatibility_version" : "7.17.0",
      "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
  }
