更改bootStart.sh的脚本为

#!/bin/sh
echo "================================="
echo "自动化部署脚本启动"

echo "停止原来运行中的工程"
APP_NAME=jardemo1

tpid=$(ps -ef | grep $APP_NAME | grep -v grep | grep -v kill | awk '{print $2}')

    echo 'Stop Process...'
    kill -15 $tpid

sleep 2
tpid=$(ps -ef | grep $APP_NAME | grep -v grep | awk '{print $2}')
if [ -n "$tpid" ]; then
    echo 'Kill Process!'

：wq保存退出再输入

chmod +x bootStart.sh

./bootStart.sh
重新运行脚本 运行成功 一切正常
