解决spring cloud服务启动之后回到命令行会自动挂掉问题
我们的springcloud微服务一般是打成jar包发布的，Linux下启动jar包和windows下一样，都是java-jar包名，实际操作过的小伙伴可能会遇到这种情况：用java-jar启动之后，再切回到命令行服务会挂掉，怎么解决呢？使用nohup命令就不会了！
例：
jar包：
micro-service/micro-eureka-server-0.0.1-SNAPSHOT.jar
启动命令：
ohupjava-jarmicro-service/micro-eureka-server-0.0.1-SNAPSHOT.jar&
启动之后用ctrl+c回到命令行就不会挂掉了，想要看看启动起来没有可以查看进程：
ps-ef|grepeureka
当然，我们也可以在启动的时候指定某些配置：
指定端口号：
nohupjava-jarmicro-service/micro-eureka-server-0.0.1-SNAPSHOT.jar--server.port=8888&
其他的依葫芦画瓢…
补充知识：springcloud创建统一配置后不能正常启动
我就废话不多说了，大家还是直接看代码吧~
