shell编写的zk、hadoop、hbase服务监控并重启服务

#!/bin/bash#zk服务器问题修复脚本#zkServer服务所在路径zkDir="/usr/local/zookeeper/bin/"zkLog='zookeeper.out'#进入zkSer

改进版：

#!/usr/bin/env bash#hadoop的sbin路径Hadoop=/usr/local/hadoop/sbin#hbase的bin路径Hbase=/usr/local/hbase/bin#zookeeper的bin路径Zk=/usr/local/zookeeper/bincd $Hadoop#关闭history与proxy服务StopHistory=`./mr-jobhistory-daemon.sh stop historyserver`StopProxy=`./yarn-daemon.sh stop proxyserver`#启动history与proxy服务StartHistory=`./mr-jobhistory-daemon.sh start historyserver`StartProxy=`./yarn-daemon.sh start proxyserver`if [ -n "$StartHistory" ]  &&  [ -n "$StartProxy" ]then	echo "historyserver and proxyserver restart Succeed!"ficd $Hbase#关闭hbase服务StopHbase=`./stop-hbase.sh`#启动hbase服务StartHbase=`./start-hbase.sh`if [ -n "$StartHbase" ]then	echo "hbase restart Succeed！" fi#关闭服务并重启cd $Zk#关闭zk服务stopZK=`./zkServer.sh stop`startZK=`./zkServer.sh start`statusZK=`./zkServer.sh status`echo $stopZK > /dev/nullif echo $startZK | grep "STARTED"then	if echo $status | grep "Mode"	then		if jps | grep "QuorumPeerMain"		then			echo "zk server start Succeed!"		fi	else		for pid in `jps | grep "QuorumPeerMain"`  			do    				#如果启动pid不为空且pid不为零  				if [ -n "$pid" ] && [ "$pid" != "QuorumPeerMain" ]  				then  					#关闭该进程  					kill -9 $pid   					#关闭zkServer  					stopZK=`./zkServer.sh stop`					echo $stopZK >/dev/null					#运行zkServer.sh命令启动zk服务					startZk=`./zkServer.sh start`					if echo $startZk  | grep "STARTED"  					then  						#查看服务状态						statusZK=`./zkServer.sh status`						if echo $							statusZK | grep "Mode"  						then							QuoPM=`jps | grep "QuorumPeerMain"`							if [ -n "$QuoPM" ]							then  								echo "zookeeper restart Succeed!"							fi  						fi  					fi 				fi		done  	fifi

然后执行：corntab -e

在文件中添加：30 2 * * * /usr/local/Reboot >>/usr/local/reboot/log

上面意思是：每天的2:30跑脚本，重新启动zk、hadoop、hbase服务
