Installing elasticsearch & running for the first time

Elastic Stack Elasticsearch
1

When I first run ./elasticsearch I get the following errors. I know I am running as root which is the cause of running elasticsearch but when I do not I get access denied to the jdk files.

When I do not run as root. I get the following output:

I can not install openjdk without being root and I think elasticsearch can not access openjdk because it is not running as root. Any suggestions?

Please don't post images of text like that, they are not always readable.

Nope, you should never run ES as root!

You should really start ES using service elasticsearch start.

3

When I run the script I am told:
"You need root privileges to run this script"

4

Then use sudo service elasticsearch start

I did and I got the same log as I 1st posted. I was using openjdk so I reconfigured everything and installed java 8 as recommended and has fixed the issue! Thanks for your help. Many more to come for sure.
