两个shell脚本，希望大家能够用上
第一个 定时抓取服务器JVM相关信息
#! /bin/sh #get_current_timeexport JAVA_HOME=/opt/jdk1.6.0_10/export PATH=$JAVA_HOME/bin:$PATHexport CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$CLASSPATH date=`date "+%Y-%m-%d-%H:%M:%S"` Root="/data/dxm/" jmapends=$Root$date"_jmap.txt"jstackends=$Root$date"_jstack.txt"jstateends=$Root$date"_jstate.txt" #start to register the jmap messageecho "start to register the jmap to "$jmapendsjmap -histo:live `jps|grep Resin |awk 'NR==1'|awk '{print $1}'` > $jmapends sleep 2 #start to register the jtack messageecho "start to register the jstack to "$jstackendsjstack -l `jps|grep Resin |awk 'NR==1'|awk '{print $1}'` > $jstackends sleep 2 #start to register the jstate messageecho "start to register the jstate message to "$jstateendsjstat -gcutil -t -h20 `jps|grep Resin |awk 'NR==1'|awk '{print $1}'` 1000 20 > $jstateends?
这个可以跑个定时器：
crontab -e
*/10 * * * * sh /timer/timer.sh ?#每十分钟抓一次
?
?
第二个脚本：比较两个版本中jar包是否相同(有改变)：
#! /bin/sh #compare the lib files's md5 int file1 with those in file2#if it only exist in file1 or one lib file's md5 is not equal i#with the other then print it to the log.txt LibPath1=$1LibPath2=$2date=`date "+%Y-%m-%d-%H:%M:%S"` LOG=$date"_log.txt"echo "-----------log file " $LOG echo LibPath1: $LibPath1echo LibPath2: $LibPath2echo LibPath1: $LibPath1 \n >> $LOGecho LibPath2: $LibPath2 \n >> $LOGecho >> $LOGecho >> $LOG for File in `ls -f $LibPath1|grep jar `;do MD5=`md5sum $1$File |awk 'NR==1'|awk '{print $1}'` File2=$LibPath2$File #echo "File2-----------------" $File2 #if the same lib file exist if [ ! -f "$File2" ]; then echo $File only exist LibPath1 echo $File only exist LibPath1 \n >> $LOG echo >> $LOG #if the same file exist in directory2 else MD52=`md5sum $File2 |awk 'NR==1'|awk '{print $1}'` if [ "$MD5" != "$MD52" ]; then echo the $File changed \n >> $LOG echo >> $LOG echo the $File changed fi fi done?
?
上的那个文件为
md5compare.sh
?
运行是可以用以下命令运行：
?
./md5compare.sh libpath1 libpath2
注意libpath1,libpath2 必须以"/" 结尾比如：
/opt/ROOT_2011-09-08-09:57:26/WEB-INF/lib/
而不是
/opt/ROOT_2011-09-08-09:57:26/WEB-INF/lib
