本文介绍了如何将SpringBoot应用打包成jar，并在Linux环境中使用shell脚本进行启动、停止和状态检查。同时，文章还讲解了在Linux上安装daemonize的必要性，以及如何通过Nginx配置反向代理，将应用服务暴露在8081端口对外提供访问。

首先我们要把spingboot 打包成jar 包

编写shell启动命令，下载是编写的一个通用的启动命令

jar_file=loveMM.jar springboot的jar
pid_file=loveMM.pid
log_file=loveMM.log 日志文件

pid_dir=/var/run/
pid_path="${pid_dir}$pid_file"

cd $(dirname "$0")

# wait_for_start(pid_file, timeout)
function wait_for_start(){
   pid_file=$1
   t=10
   if test $# -ge 2 && test $2 -gt 0
   then
       t=$2
   fi

   while test $t -ge 0
   do
       if test -s $pid_file
       then
           pid=`cat "$pid_file"`
           if kill -0 $pid 2>/dev/null
           then
               # success
               return 0
           fi
