1、编辑shell

命令：
cd /data
mkdir -p task
cd task
vi checkAlive.sh

2、编辑以下内容

!/bin/sh

#tomcat目录路径
TOMCATNAME=/data/tomcat-6.0.45/

#日志路径
log_path=/data/tomcat-6.0.45/logs/checkIsAlive/

echo “———- currentTime: $(date +%Y%m_%d%t%H:%M:%S) start ————-“ >>${log_path}checkIsAlive.log

#获取请求返回码
return=curl -s -w %{http_code} -o /dev/null [http://127.0.0.1:8081/](http://192.168.1.95:8081/eportal/admin)web

echo “STATUS:”$return >>${log_path}checkIsAlive.log

#tomcat 进程id
javapid=ps aux|grep java|grep -v grep|grep tomcat-6.0.45|awk '{print $2}'

echo “PID:”$javapid >>${log_path}checkIsAlive.log

#返回码$return不等于200
if [ $return -ne 200 ];then
echo “service Is bad !” >>${log_path}checkIsAlive.log
if [ -n “$javapid” ]; then
echo “tomcat is alive” >>${log_path}checkIsAlive.log
kill -9 $javapid

else
echo “tomcat is down “ >>${log_path}checkIsAlive.log

fi

等待30s
sleep 30

/data/tomcat-6.0.45/bin/startup.sh
else
echo “tomcat service Is ok” >>${logpath}checkIsAlive.log
fi

echo “———- currentTime: $(date +%Y%m_%d%t%H:%M:%S) end ————-“ >>${log_path}checkIsAlive.log

3、保存退出

4、验证

命令：
sh checkAlive.sh
查看日志确认是否执行成功
tail -f /data/tomcat-6.0.45/logs/checkIsAlive/checkIsAlive.log

5、设置定时任务

命令：crontab e
#10分钟检测一次
/10 * sh /data/task/checkAlive.sh
