shell腳本監控tomcat狀態以及自動清理tomcat日誌

監控用的

#!/bin/bash
# 
#*/2 * * * *   sh /home/apache-tomcat-7.0.61/bin/detectionTMT.sh




# 獲取tomcat進程ID（其中[grep -w 'tomcat']代碼中的tomcat需要替換爲你的tomcat文件夾名）
TomcatID=$(ps -ef | grep "org.apache.catalina.startup.Bootstrap" | grep -v 'grep' | awk '{print $2}')

# tomcat啓動程序(這裏注意tomcat實際安裝的路徑)
StartTomcat=./startup.sh

#定義要監控的頁面地址
WebUrl=http://192.169.160.19:8088/mp_topics/jsp/100/to_100.jsp

#日誌輸出

Monitor()
{

if [ -n "$TomcatID" ];then #這裏判斷Tomcat進程是否存在
        echo "[info]當前tomcat進程ID爲:$TomcatID,繼續檢測頁面..."

清理日誌用的

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")
#遍歷這個數組
for file in $files
do
#截取文件的後綴時間
#date2="${file##*.}"
#獲取該文件的創建時間
datatime=$(stat $file|grep Modify|awk '{print $2}'|sed s/-//g)
#如果這個文件的時間小於三天前的時間則刪除這個文件
        if [ $datatime -lt $today ]; then
                rm -rf  $file
        fi
done
}
