tomcat检测脚本
最近写了个简单的tomcat检测脚本。可以进行简单的进程和页面检测。#!/bin/bash

# fun:检测tomcat进程和页面是否正常

echo "Tomcat启动失败"
else

fi
}
KillTom() #杀死tomcat函数

ps aux|grep $TomcatName|grep -Ev "grep|$0"|awk -F " " '{print $2}'|xargs kill -9 #杀掉tomcat进程
TomcatNum=`ps aux|grep $TomcatName|grep -Ev "grep|$0"|awk -F " " '{print $2}'|wc -l` #检测是否杀掉

echo "Tomcat 进程全部杀死"
else

fi
}

do
