Configuring logstash

Question

I'm trying to install elasticsearch components and following those installation steps

Downloaded and unzipped those:

elasticsearch-7.4.0-windows-x86_64
kibana-7.4.0-windows-x86_64
logstash-7.4.0

Then created logstash-simple.conf

input { stdin { } }
output {
  elasticsearch { hosts => ["localhost:9200"] }
  stdout { codec => rubydebug }
}

in logstash-7.4.0\logstash-7.4.0\bin and then run this:

logstash -f logstash-simple.conf

it throws me an error

"Elasticsearch Unreachable"

I tried to tun this elasticsearch-7.4.0-windows-x86_64\elasticsearch-7.4.0\bin\elasticsearch.bat , command prompt opens, it loads something and then command prompt closes automatically, so I'm not sure whether there are errors if any. This doesn't solve above error.

How I can solve above error?

Off topic . Why when running elasticsearch.bat it refers to JDK within C:\Program Files (x86)\Java , and not within C:\Program Files\Java . How I can install Java 11 to C:\Program Files (x86)\Java , I was only able to install that to C:\Program Files\Java

Answer 1

After long time, I finally figured it out. The reason it was failing is because it was referring to 32 bit Java version. I just changed JAVA_HOME path to 64 bit version, and elastic search runs, so does logstash
