实现方式

1.inotify+rsync 实时同步文件 （直接同步，后台运行，会降低jenkins应用性能）
2.keepalive vip 监测状态自动重启从master

同步方案

#!/bin/bash
host=192.168.101.1
src=/data/jenkins/home/
#src=/data/jenkins_test/home/
#des=/data/jenkins_test/home/
inotify=/usr/local/include
#${inotify}/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f%e' -e  close_write,modify,delete,create,attrib,move $src | while read files
${inotify}/bin/inotifywait -mrq  --exclude '(^.*/~.*|^.*\.swp$|.*~|.swx|4913|tmp$|caches)'  --timefmt '%d/%m/%y %H:%M' --format '%T %w%f %e' -e  close_write,modify,delete,create,attrib,move $src | while read date time file event
do
#       echo "date:$date"
#       echo "time:$time"
#       echo "file:$file"
#       echo "event:$event"
#        echo "---------------------------------------------------------------------------------------------------------"
        case $event in
          MODIFY|CREATE|MOVE|MODIFY,ISDIR|MOVED_FROM|MOVED_FROM,ISDIR|CLOSE_WRITE,CLOSE|ATTRIB)
                  #echo $event'-'$file
                  #echo "rsync -avuzP  --progress  $file $host:$file"
                  rsync -a $file $host:$file
                  if [ $? -ne 0 ]
                  then
                        dir=`dirname $file`
                        echo $file
                        rsync -a    $dir/ $host:$dir/
                  fi
              ;;
          CREATE,ISDIR)
                  rsync -a  $file/ $host:$file/
              ;;
          DELETE|DELETE,ISDIR)
                  echo $event'-'$file >>delete.txt
              ;;
        esac
        #rsync -avuzP --delete --progress  $var $host:$var
        #echo "${files} was rsynced" >> /tmp/jenkins_rsync.log 2>&1
