### 监控用的 ###

#!/bin/bash
    # 
    #*/2 * * * *   sh /home/apache-tomcat-7.0.61/bin/detectionTMT.sh
    
    
    
    
    # 获取tomcat进程ID（其中[grep -w 'tomcat']代码中的tomcat需要替换为你的tomcat文件夹名）
    TomcatID=$(ps -ef | grep "org.apache.catalina.startup.Bootstrap" | grep -v 'grep' | awk '{print $2}')
    
    # tomcat启动程序(这里注意tomcat实际安装的路径)
    StartTomcat=./startup.sh
    
    #定义要监控的页面地址
    WebUrl=http://192.169.160.19:8088/mp_topics/jsp/100/to_100.jsp
    
    #日志输出
    GetPageInfo=/home/apache-tomcat-7.0.61/logs/TomcatMonitor.Info
    TomcatMonitorLog=/home/apache-tomcat-7.0.61/logs/TomcatMonitor.log
    
    Monitor()
    {
    echo "[info]开始监控tomcat...[$(date +'%F %H:%M:%S')]"
    if [ -n "$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 -s -o $GetPageInfo -m 10 --connect-timeout 10 $WebUrl -w %{http_code})
                    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 $TomcatID # 杀掉原tomcat进程
                                    echo "杀掉原tomcat进程$TomcatID"
                                    sleep 3
                            cd /home/apache-tomcat-7.0.61/bin/ &&  $StartTomcat
                    fi
    else
            echo "[error]tomcat进程不存在!tomcat开始自动重启..."
            echo "[info]$StartTomcat，请稍候..."
             cd /home/apache-tomcat-7.0.61/bin/ && $StartTomcat
    fi
    echo "--------------------------"
    }
    Monitor>>$TomcatMonitorLog

### 清理日志用的 ###

datess=$(date "+%Y-%m-%d   %H:%M:%S")
    echo  "-------------------------------------$datess--------------------------------------"    >>  /home/apache-tomcat-7.0.88/logs/cleanlogrecording.txt
    
    
    cleanLog () {
    #3天前的日期
    today=$(date +%Y%m%d --date="-3 day")
    #遍历这个数组
    for file in $files
    do
    #截取文件的后缀时间
    #date2="${file##*.}"
    #获取该文件的创建时间
    datatime=$(stat $file|grep Modify|awk '{print $2}'|sed s/-//g)
    #如果这个文件的时间小于三天前的时间则删除这个文件
            if [ $datatime -lt $today ]; then
                    rm -rf  $file
            fi
    done
    }
    
    #需要清除的日志路径   下方类似
    files=/home/apache-tomcat-7.0.88/logs/catalina.*.log
    
    cleanLog $files
    
    files=/home/apache-tomcat-7.0.88/logs/host-manager.*.log
    
    cleanLog $files
    
    files=/home/apache-tomcat-7.0.88/logs/localhost.*.log
    
    cleanLog $files
    
    files=/home/apache-tomcat-7.0.88/logs/localhost_access_log.*.txt
    
    cleanLog $files
    
    files=/home/apache-tomcat-7.0.88/logs/manager.*.log
    
    cleanLog $files
    
    #files=/home/logging/hs/bubble/spring.log.*
    #cleanLog $files
    
    
    cat /dev/null  >  /home/apache-tomcat-7.0.88/logs/catalina.out

### 配合linux的crontab定时任务  即可达到效果 ###
