• jenkins发布回滚脚本
  该脚本内部启动了两个java启动命令，中间间隔了60s，等待第一个jar包起来，然后判断了一下，再启动另一个jar
  命令示例：sh deploy_rollback.sh Deploy 16 14

BUILD_TYPE=$1
BUILD_NUMBER=$2
Version=$3

case $BUILD_TYPE in
  Deploy)
    echo "BUILD_TYPE:$BUILD_TYPE"
    path="bak/$BUILD_NUMBER"
    if [ -d $path ];
    then
        cp -f *.jar $path
        cp -f *.jar  /usr/local/project/kids-world/kids-world-api.jar
        cp -f *.jar  /usr/local/project/kids-world-2/kids-world-api-2.jar
    else
        echo "The files is not exists "
    fi
    echo "completing"
    ;;
  Rollback)
    echo "BUILD_TYPE:$BUILD_TYPE"
    echo "Version:$Version"
    cp -f bak/$Version/*.jar  ./
    cp -f *.jar  /usr/local/project/kids-world/kids-world-api.jar
    cp -f *.jar  /usr/local/project/kids-world-2/kids-world-api-2.jar
    ;;
  *)
  exit
      ;;
esac

rm -f kids-world-api.jar

sh /usr/local/project/kids-world/service.sh   jrestart

sleep 60s


JAR_FILE=/usr/local/project/kids-world/kids-world-api.jar

pid=`ps -ef |grep $JAR_FILE |grep -v grep |awk '{print $2}'`

if [ ! -n "$pid" ]; then
    echo "kids 8081 not runing"
else
    echo "kids 8081 is runing"
    echo "start kids 8082"
    sh /usr/local/project/kids-world-2/service.sh   jrestart
fi

• 删除备份脚本
  命令示例：sh rv_bak.sh

ReservedNum=100  #保留文件数
FileDir=/usr/local/project/kids-prod/bak
date=$(date "+%Y%m%d-%H%M%S")

cd $FileDir   #进入备份目录
FileNum=$(ls -l | grep '^d' | wc -l)   #当前有几个文件夹，即几个备份

while(( $FileNum > $ReservedNum))
do
    OldFile=$(ls -rt | head -1)         #获取最旧的那个备份文件夹
    echo  $date "Delete File:"$OldFile
    rm -rf $FileDir/$OldFile
    let "FileNum--"
done
