CentOS服务器上监控tomcat，如果挂掉则重启

该脚本用于监控tomcat服务器是否可用，如果服务不可用则重启tomcat

略微修改后也可以用于其他服务的监控

monitor.sh 脚本如下

#!/bin/sh


# 定义要监控的页面地址
WebUrl="http://xxxxxxx.com"
GetPageInfo=/dev/null


while [ "1" = "1" ]
do

TomcatServiceCode=$(curl -s -o $GetPageInfo -m 10 --connect-timeout 10 $WebUrl -w %{http_code})
echo "`date "+%Y-%m-%d %H:%M:%S"` : TomcatServiceCode:"$TomcatServiceCode

#如果返回不是http 200 ，说明tomcat已经挂断
#需要杀掉进程，并重启tomcat
  if [ $TomcatServiceCode -eq 200 ];then
     echo "`date "+%Y-%m-%d %H:%M:%S"` :tomcat is okay."
  else
    ID=`ps -ef | grep tomcat | grep -v "grep" | awk '{print $2}'`
    echo $ID    
    for id in $ID
    do
     kill -9 $id
     echo "`date "+%Y-%m-%d %H:%M:%S"` : killed $id"
    done
    echo "`date "+%Y-%m-%d %H:%M:%S"` : PID have been killed"
    echo "`date "+%Y-%m-%d %H:%M:%S"` : begin to restart the tomcat."
    service tomcat start
    echo "`date "+%Y-%m-%d %H:%M:%S"` : tomcat have been restarted."
  fi
echo "check done."
echo "`date "+%Y-%m-%d %H:%M:%S"` sleep 60s and wait next check.."
sleep 60s 
done

启动脚本

nohup ./monitor.sh >/dev/null 2>&1
