Linux监听Tomcat

1.编写如下脚本，不需要多次判断的去掉循环

#!/bin/bash
count=4
seconds=2
echo $(date '+%Y-%m-%d %H:%M:%S')" Test Start"
for i in $(seq $count)
do
	webs=$(/usr/bin/wget -S --spider --tries=3 --timeout=3 http://localhost:8080/test/status.html 2>&1 | grep HTTP/1.1|awk '{print $2}')
	if [ "$webs" = "200" ]
	then
		echo $(date '+%Y-%m-%d %H:%M:%S')" Test success"
		break;
	else
		echo $(date '+%Y-%m-%d %H:%M:%S')" Test failed "$i
		if [ $i -eq $count ]
		then
			pid=$(ps -ef | grep tomcat |grep -w '/opt/tomcat' | grep -v grep |awk '{print $2}')
			if [ "$pid" != "" ]
			then
				kill -9 $pid
				echo "killed $pid"
				echo $(/opt/tomcat/bin/startup.sh)
			else
				echo "pid is null"
			fi
		else
			sleep $[$i*$seconds]s		
		fi
	fi
done
echo $(date '+%Y-%m-%d %H:%M:%S')" Test End"
echo ""

2.crontab -e添加定时任务
