Hi, bellow is service script, it has some small bugs but works fine for me:
#!/bin/sh
# ElastiSearch daemon start/stop script.
# Comments to support chkconfig on RedHat Linux
# chkconfig: 2345 64 36
#title : elasticsearch
#description : This script is used such a damon/service start/stop script.
#author : Peter TAKAC / AssmodeuS
#date : 20150210
#version : 0.15
#usage : service elasticsearch
#notes : service start/stop script, also check the conf path. if
proces with the same path runs, it will not start it
#bash_version : 3.2.51(1)
