# 72. SpringBoot应用部署 - 在linux环境将jar制作成service
# 概述
基本的java -jar运行方式，和这种运行方式的缺陷。
# Java -jar运行？
Linux 运行jar包基本命令：
# 当前ssh窗口被锁定，可按CTRL + C打断程序运行，或直接关闭窗口，程序退出
java -jar XXX.jar
# &代表在后台运行。当前ssh窗口不被锁定，但是当窗口关闭时，程序中止运行。
java -jar XXX.jar &

nohup命令， nohup 意思是不挂断运行命令,当账户退出或终端关闭时,程序仍然运行
# 当用 nohup 命令执行作业时，缺省情况下该作业的所有输出被重定向到nohup.out的文件中。
nohup java -jar XXX.jar &
# 输出重定向到temp.txt文件
nohup java -jar XXX.jar >temp.txt &
# 程序在后台运行，当ssh窗口关闭，程序正常运行，且不会输出文件
nohup java -jar xx.jar >/dev/null 2>&1 &

# 这种运行方式的缺陷
这种运行方式有何缺陷呢？
- 不优雅
- 无法向Linux服务一样简单易用，具备start,stop,restart等service操作方式。以及开机自启等。
# 在Linux环境封装service
加入我们编译出了一个tech_arch-0.0.1-RELEASE.jar，如何将它封装成service呢？
# 文件准备
