which: no java in (/sbin:/bin:/usr/sbin:/usr/bin)
Could not find any executable java binary. Please install java in your PATH or set JAVA_HOME

Answer 1

First of all, you cannot log in as the root user. The sudo default is the root user. You need to specify another user name when sudoing. For example: sudo -iu user_a bin/elasticsearch

Answer 2

A new user has been added, please start it with the new user later.
I wonder if any of the experts have a way to start it under root?

Answer 3

vi /etc/sysconfig/elasticsearch
Write JAVA_HOME=/root/jdk1.8.0_60 to the file, save it and start it
service elasticsearch start
Starting elasticsearch: [OK]

Answer 4

Correct answer on the 3rd floor, I started it as root user

Answer 5

@geekfranca
My Logstash is version 2.2.2, the system environment is ubuntu kylin 16, and then I installed it from the logstash_2.2.2-1_all.deb file downloaded from [official website]. I used an ordinary user and executed sudo service logstash configtest , the prompt is as follows:

Could not find any executable java binary. Please install java in your PATH or set JAVA_HOME.

Install the method mentioned by @geekfranca, modify the /etc/init.d/logstash file, and the execution is successful. The principle should be the same
