Jenkins如何实现自动打包部署linux

#!/bin/sh
#kill tomcat pid
export BUILD_ID=$BUILD_ID

# 1.关闭tomcat
pidlist=`ps -ef|grep 8081|grep -v "grep"|awk '{print $2}'`
function stop(){
if [ "$pidlist" == "" ]
 then
  echo "----tomcat 已经关闭----"
  
 else
  echo "tomcat进程号 :$pidlist"
  kill -9 $pidlist
  echo "KILL $pidlist:"
fi
}

stop
pidlist2=`ps -ef|grep 8081|grep -v "grep"|awk '{print $2}'`
if [ "$pidlist2" == "" ]
  then 
    echo "----关闭tomcat成功----"
else
  echo "----关闭tomcat失败----"
fi



# 2.移除原来tomcat中webapps中的项目文件夹
rm -rf /usr/local/apache-tomcat-8081/webapps/ROOT/*
rm -rf /usr/local/apache-tomcat-8081/webapps/qingzhutool*
# 3.复制jenkins生成的war包到tomcat中webapps中
cp -r /home/war-jar-bak/$BUILD_ID/qingzhutool.jar /usr/local/apache-tomcat-8081/webapps
sleep 3s
# 4.修改war包的名称
#mv /usr/local/tomcat_mobile/webapps/mobile.war /usr/local/tomcat_mobile/webapps/ROOT.war
# 5.启动tomcat
cd /usr/local/apache-tomcat-8081/bin
sh startup.sh
