You can run it in background as two ways,
1. Nohup
2. Creating service script and put it in init.d folder
Nohup
Eg: nohup ./bin/elasticsearch
Service script
Use the following script,
#!/bin/bash
### BEGIN INIT INFO
# Provides: Elasticsearch
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Runs elasticsearch daemon
# Description: Runs the elasticsearch daemon as a non-root user
### END INIT INFO
# Process name

DESC="Elasticsearch"
PROG="/etc/init.d/elasticsearch"

ELASTICSEARCH_BIN=/opt/elasticsearch-2.3.0/bin

# Begin Script
RETVAL=0
if [ `id -u` -ne 0 ]; then
echo "You need root privileges to run this script"
exit 1

start() {
echo -n "Starting $DESC : "
pid=`pidofproc -p $PID_FILE elasticsearch`
if [ -n "$pid" ] ; then
echo "Already running."
exit 0
else
# Start Daemon
if [ ! -d "$PID_FOLDER" ] ; then
mkdir $PID_FOLDER
fi
daemon --user=$DAEMON_USER --pidfile=$PID_FILE $DAEMON 1>"$ELASTICSEARCH_LOG" 2>&1 &
sleep 2
pidofproc node > $PID_FILE
RETVAL=$?
[[ $? -eq 0 ]] && success || failure
echo
[ $RETVAL = 0 ] && touch $LOCK_FILE
return $RETVAL
fi
}
reload()
{
echo "Reload command is not implemented for this service."
return $RETVAL
}
stop() {
echo -n "Stopping $DESC : "
killproc -p $PID_FILE $DAEMON
RETVAL=$?
echo
[ $RETVAL = 0 ] && rm -f $PID_FILE $LOCK_FILE
}
