The first thing to do is to have a script like demo

#!/bin/bash## Etcd This shell script takes care of starting and stopping etcd## Chkconfig:2345  the  -# # # BEGIN INIT info# provides:etcd# Required-Start: $network $syslog # Required-Stop: $network $syslog # Default-start:# Default-stop:# Short-Description:start and stop etcd### END INIT INFO # # Source function library.#./etc/rc.d/init.d/Functionsexport Java_home=/Usrexport PATH= $JAVA _home/Bin: $PATHGOPATH=/opt/etcdrepo/Etcdetcd_home=$GOPATHEtcd_pid () {echo ' PS aux| Grep"etcd\>"| Grep-v grep | Awk'{print $}'| Tail-n1'} start () {PID=$ (etcd_pid)if[-N"$pid"] then echo"Etcd is already running (PID: $pid)"    Else#Start Etcd Echo"starting ETCD"Ulimit-N100000umask007sudo $ETCD _home/bin/etcd-data-dir machines/machine1-name Machine1 & >Log.txt fireturn 0} stop () {PID=$ (etcd_pid)if[-N"$pid"] then echo-n-e"\nkilling processes which didn ' t stop after $SHUTDOWN _wait seconds"Kill-9$pidElseEcho"Etcd is not running"fireturn 0}  Case$1 inchstart) Start; stop) stop;; restart) stop start;; status) PID=$ (etcd_pid)if[-N"$pid"] then echo"Etcd is running with PID: $pid"    ElseEcho"Etcd is not running"fi;; Esacexit0

2. Put this script under/ETC/INIT.D or/ETC/RC.D/INIT.D

3. Set permissions

sudo chmod 777 Demosudo chkconfig--add demosudo chkconfig--list Demosudo Service Demo start  when the service is not found
