One Node Setup Exercise

1. Login into your sandbox using SSH
2. Update package list:

   sudo apt-get update
   

3. Install Java Runtime Environment:

   sudo apt-get install default-jre -y
   

4. Download and install Public Signing Key:

   curl https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
   

5. Add repository definition:

   echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" \
    | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list
   

6. Install Elastic Search:

   sudo apt-get update && sudo apt-get install elasticsearch
   

7. Start Elastic Search service:

   sudo systemctl start elasticsearch
   

8. We will be using 'curl' to troubleshoot the setup and to run our first queries before we install and configure Kibana
9. Give it a moment to finish the initialization and verify it is running:

   curl localhost:9200
   

10. Expected response:

{ "name" : "ip-172-31-2-16", "cluster_name" : "elasticsearch", "cluster_uuid" : "ZH5wkpEESPqf8YwKWajRQA", "version" : { "number" : "7.14.0", "build_flavor" : "default", "build_type" : "deb", "build_hash" : "dd5a0a2acaa2045ff9624f3729fc8a6f40835aa1", "build_date" : "2021-07-29T20:49:32.864135063Z", "build_snapshot" : false, "lucene_version" : "8.9.0", "minimum_wire_compatibility_version" : "6.8.0", "minimum_index_compatibility_version" : "6.0.0-beta1" }, "tagline" : "You Know, for Search" }

```

11. Posting the first document:

    curl -XPOST 'localhost:9200/orders/_doc/1?pretty=true' \
      -H 'content-type: application/json' \
      -d '{
      "id": "1", 
      "placedOn": "2016-10-17T13:03:30.830Z",
      "status": "shipped"
    }'

12. Expected Response:

    {
      "_index" : "orders",
      "_type" : "_doc",
      "_id" : "1",
      "_version" : 1,
      "result" : "created",
      "_shards" : {
        "total" : 2,
        "successful" : 1,
        "failed" : 0
      },
      "_seq_no" : 0,
      "_primary_term" : 1
    }

13. _seq_no: unique sequence of the indexing operation
14. _primary_term: shard id where primary copy stored
15. First query:

    curl 'localhost:9200/orders/_doc/_search?pretty=true&q=id:1'
    

16. Where are: doc id, document data, index name, type name, and search score?
17. Next time you can run the setup script at once:

    curl https://gist.githubusercontent.com/vkhazin/6b0e44387368439af8e1750a1a0fa008/raw/02bbac1f7bf0c76e3dd49284da28f253f8ad5c73/Install%2520ElasticSearch%2520v7%2520on%2520Ubuntu%252018.04 | bash -
