设置Zookeeper开机自启

首先在 /etc/init.d/ 目录下创建启动文件 zookeeper：

写入内容：

#!/bin/bash
# chkconfig: 2345 20 90
# description: zookeeper

source /etc/profile

case $1 in
start)
	su - hadoop -c "${ZOOKEEPER_HOME}/bin/zkServer.sh start"
	if  [ "$?" = "0" ]
	then
		echo "zookeeper is running . . ."
	fi
	;;
stop)
	su - hadoop -c "${ZOOKEEPER_HOME}/bin/zkServer.sh stop"
	if  [ "$?" = "0" ]
        then
                echo "zookeeper is stopped . . ."
        fi
	;;
status)
	su - hadoop -c "${ZOOKEEPER_HOME}/bin/zkServer.sh status"
	;;
restart)
	su - hadoop -c "${ZOOKEEPER_HOME}/bin/zkServer.sh restart"
	;;
*)
	echo "require start | stop | status | restart !"
	;;
esac

现在就可以使用如下命令来控制 zookeeper 了：

service zookeeper start | stop | status | restart

给予文件可执行权限：
