tomcat进程检测并自动重启

检测tomcat进程脚:tomcatMonitor.sh

#!/bin/sh 
tomcatName=tomcat3
tomcatPath=/tomcat/tomcat3
selfName=tomcatMonitor
pid=`ps aux | grep $tomcatName | grep -v grep | grep -v $selfName | awk '{print $2}'` 
echo $pid 
if [ "$pid" -lt -1 ]; then
{ 
   echo ===========shutdown================ 
   $tomcatPath/bin/shutdown.sh 
   sleep 3 
   pid=`ps aux | grep $tomcatName | grep -v grep | grep -v $selfName  | awk '{print $2}'` 
   if [ -n "$pid" ] 
   then 
    { 
      sleep 3 
      echo ========kill tomcat begin============== 
      echo $pid 
      kill -9 $pid 
      echo ========kill tomcat end============== 
    } 
   fi 
   sleep 3 
   echo ===========startup.sh============== 
   $tomcatPath/bin/startup.sh 
} 
else 
echo ========== $tomcatName is running =============== 
fi

添加可执行权限
#chmod 775 tomcatMonitor.sh

crond配置每5分钟检测一次
#crontab -e

*/5 * * * * su - root -c /root/tomcatMonitor.sh

使配置生效
#service crond stop
#service crond start
