监控tomcat进程是否正常的脚本

编写monitor.sh监控tomcat是否正常，否则重启

#!/bin/sh
# 获取tomcat进程ID  /disk/tomcat8
TomcatID=$(ps -ef |grep tomcat |grep -w 'tomcat8'|grep -v 'grep'|awk '{print $2}')
# tomcat启动程序(这里注意tomcat实际安装的路径)  
StartTomcat=/disk/tomcat8/bin/startup.sh 
# 定义要监控的页面地址  
WebUrl=http://ip:8088/login
# 日志输出 
TomcatMonitorLog=/disk/monitor/TomcatMonitor.log  

Monitor() 
{  
  echo "[info]开始监控tomcat...[$(date +'%F %H:%M:%S')]"  
  if [[ $TomcatID ]];then # 这里判断TOMCAT进程是否存在  
    echo "[info]当前tomcat进程ID为:$TomcatID,继续检测页面..."  
    # 检测是否启动成功(成功的话页面会返回状态"200")
    TomcatServiceCode=$(curl -I -m 10 -o /dev/null -s -w %{http_code} $WebUrl)
    if [ $TomcatServiceCode -eq 200 ];then  
        echo "[info]页面返回码为$TomcatServiceCode,tomcat启动成功,测试页面正常......"  
    else  
        echo "[error]tomcat页面出错,请注意......状态码为$TomcatServiceCode,错误日志已输出到$GetPageInfo"  
        echo "[error]页面访问出错,开始重启tomcat"  
        kill -9 $TomcatID  # 杀掉原tomcat进程  
        sleep 3  
        rm -rf $TomcatCache # 清理tomcat缓存  
        $StartTomcat  
    fi  
  else  
    echo "[error]tomcat进程不存在!tomcat开始自动重启..."  
    echo "[info]$StartTomcat,请稍候......"  
    #rm -rf $TomcatCache  
    $StartTomcat  
  fi  
  echo "------------------------------"  
}
