　# You can put your own initialization stuff in here if you don't
　# want to do the full Sys V style init stuff.

　touch /var/lock/subsys/local
　export JAVA_HOME=/usr/java/jdk1.8.0_221　　　　　　　　--jdk的路径，自己安装的目录
　/home/zookeeper/zookeeper-3.4.14/bin/zkServer.sh start　　 --zookeeper的zkServer.sh的路径

(2) registered as a service: Add to /etc/rc.d/init.d next directory, zookeeper script

　　cd /etc/rc.d/init.d

　　touch zookeeper

　　ls -al - do not have permission to view, modify permissions

　　chmod +x zookeeper

　　case $1 in
　　　　start) su root /home/zookeeper/zookeeper-3.4.14/bin/zkServer.sh start;;
　　　　stop) su root /home/zookeeper/zookeeper-3.4.14/bin/zkServer.sh stop;;
　　　　status) su root /home/zookeeper/zookeeper-3.4.14/bin/zkServer.sh status;;
　　　　restart) su /home/zookeeper/zookeeper-3.4.14/bin/zkServer.sh restart;;
