Failed to start elasticsearch 7.0 from service

[yama2k]

Hi all. I' m trying to start elasticsearch from service following this instruction.
https://www.elastic.co/guide/en/elasticsearch/reference/7.0/starting-elasticsearch.html
I cannot start elasticsearch.
Cannot find java even though PATH and JAVA_HOME are set.

How can i fix this ?

user1@ubuntu-trusty-1:~$ sudo -i service elasticsearch start
Could not find any executable java binary. Please install java in your PATH or set JAVA_HOME

The service is not using the root user to run.

Thank you very much to taking your time.
I'm not familiar with Ubuntu. How can I fix this.
By editting /etc/environment is correct ?

[dadoonet (David Pilato)]

Not familiar either. But in 7.0 you don't normally need to provide a jvm yourself.
So I'd just try to follow the installation guide, step by step.

May be someone else can help though.

@shrikantgulia
Thank you for additional information.
in my case, installed with apt-get.

@dadoonet @shrikantgulia
Thank you very much. I resolved it by own.

I installed Elasticsearch by apt-get, but installed java by tar.
That's the reason why I faced to this issue.
By installing java by apt-get was the way to resolve.
Thank you.
