如何在Linux系统中将Spring Boot应用程序打包为可执行jar as a Service ?这是推荐的方法吗，还是应该将这个应用程序转换为war并将其安装到Tomcat中?
目前，我可以从屏幕会话运行Spring引导应用程序，这很好，但需要在服务器重新启动后手动启动。
我正在寻找的是一般的建议/方向或样本init。D脚本，如果我的方法与可执行jar是适当的。

I don't know of a "standard" shrink-wrapped way to do that with a Java app, but it's definitely a good idea (you want to benefit from the keep-alive and monitoring capabilities of the operating system if they are there). It's on the roadmap to provide something from the Spring Boot tool support (maven and gradle), but for now you are probably going to have to roll your own. The best solution I know of right now is Foreman, which has a declarative approach and one line commands for packaging init scripts for various standard OS formats (monit, sys V, upstart etc.). There is also evidence of people having set stuff up with gradle (e.g. here).
我的SysVInit脚本Centos 6 / RHEL(还不理想)。这个脚本需要ApplicationPidListener。
/etc/init.d/app的源代码

配置文件/etc/sysconfig/app示例:
exec=/opt/jdk1.8.0_05/jre/bin/java
user=myuser
app_home=/home/mysuer/
app_args="-jar app.jar"
pid=$app_home/app.pid
我试图使springboot应用程序呈现为“init”。D”风格的shell脚本与压缩Java应用程序钉在最后
通过符号链接这些脚本从/etc/init.D /spring-app到/opt/spring-app.jar，并chmod jar使其可执行。D /spring-app启动/etc/init。D /spring-app stop”和其他可能的状态工作
假设是init。来自springboot的d风格脚本看起来他们有必要的魔法字符串(像# Default-Start: 2 3 4 5) chkconfig将能够将其作为“服务”添加。
但是我想让它和systemd一起工作
为了做到这一点，我尝试了上面其他答案中的许多食谱，但在Centos 7.2和Springboot 1.3上，它们都不适合我。大多数情况下，它们会启动服务，但无法跟踪pid
最后，我发现下面的方法对我有用，当/etc/init.D链接也到位了。一个类似于下面的文件应该安装为/usr/lib/systemd/system/spring-app.service
[Unit]
Description=My loverly application
After=syslog.target
[Service]
Type=forking
PIDFile=/var/run/spring-app/spring-app.pid
ExecStart=/etc/init.d/spring-app start
SuccessExitStatus=143
