ELK installation steps

### Install Elasticsearch, Logstash & Kibana ###

### Check Java version ###

Elasticsearch and Logstash require Java 8 or later. Install or update as needed - use the [official Oracle distribution](http://www.oracle.com/technetwork/java/javase/downloads/index.html) or an open-source distribution such as [OpenJDK](http://openjdk.java.net/). To check your Java version, run the following command: `java -version`.

### Install Elasticsearch ###
*	Download the [Elasticsearch binary package](https://www.elastic.co/downloads/elasticsearch) for your platform.
*	Extract the `.zip` or `tar.gz` archive file

(see (https://www.elastic.co/guide/en/elasticsearch/reference/current/_installation.html) for more help)

### Install Logstash ###

### Test Installation ###

### Elasticsearch ###

Open a new shell window and run Elasticsearch. 

<path_to_elasticsearch_root_dir>/bin/elasticsearch 

Elasticsearch should now be running on port 9200. To test, point your browser at port 9200 (`http://localhost:9200`). You should see output similar to the following with status code of 200. 

```
{
  "name" : "TS9xPKz",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "Wk2WMGpOQZaoLWj7BLjyuQ",
  "version" : {
    "number" : "6.7.0",
    "build_flavor" : "default",
    "build_type" : "deb",
    "build_hash" : "8453f77",
    "build_date" : "2019-03-21T15:32:29.844721Z",
    "build_snapshot" : false,
    "lucene_version" : "7.7.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}
```

### Logstash ###

To test your Logstash installation, run the following command in a new shell:

<path_to_logstash_root_dir>/bin/logstash -e 'input { stdin { } } output { stdout {} }'


Type `checking logstash!` at the command prompt. If Logstash is correctly installed, you should see:

checking logstash!
2019-03-28T01:22:14.405+0000 0.0.0.0 checking logstash!

Exit Logstash using `CTRL-D` command.

### Kibana ###

Open a new shell window and run Kibana. 

<path_to_kibana_root_dir>/bin/kibana 

Kibana should now be running on port 5601. To test, point your web browser at port 5601 (`http://localhost:5601`). You should see the Kibana UI.
