方便自己的应用，制作一个elk的自启动脚本

#!/bin/shPATH=$PATH. /etc/init.d/functionsstart() {    if [ `ps aux|grep elasticsearch | grep -v grep|wc -l` -eq 0 ];then        if [ `whoami` == elk ];then          /elk/elasticsearch-6.3.0/bin/elasticsearch -d          action "start elasticsearch:" true        else          su - elk -c "/elk/elasticsearch-6.3.0/bin/elasticsearch -d"          if [ $? -eq 0 ];then             touch /var/lock/subsys/elasticsearch             action "start elasticsearch:" true          else             action "start elasticsearch:" false          fi        fi    else        echo "elasticsearch is running"    fi}stop() {    if [ `ps aux|grep elasticsearch | grep -v grep|wc -l` -eq 0 ];then         echo "No running program found elasticsearch"    else        ps_uid=`ps aux|grep elasticsearch | grep -v grep | awk '{print $2}'`        kill -9 $ps_uid        [ $? -eq 0 ] && rm -f /var/lock/subsys/elasticsearch        action "elasticsearch is stop" true    fi}restart() {    stop    start}case "$1" instart)    start    ;;stop)    stop    ;;restart)    stop    start    ;;*)    echo $"Use $0 start|stop|restart"esac
