這篇文章主要介紹了解決spring cloud服務啟動之后回到命令行會自動掛掉問題，具有很好的參考價值，希望對大家有所幫助。一起跟隨小編過來看看吧
我們的spring cloud微服務一般是打成jar包發(fā)布的，Linux下啟動jar包和windows下一樣，都是java -jar 包名，實際操作過的小伙伴可能會遇到這種情況：用java -jar啟動之后，再切回到命令行服務會掛掉，怎么解決呢？使用nohup命令就不會了！
例：
jar包：
micro-service/micro-eureka-server-0.0.1-SNAPSHOT.jar
啟動命令：
ohup java -jar micro-service/micro-eureka-server-0.0.1-SNAPSHOT.jar &
啟動之后用 ctrl+c 回到命令行就不會掛掉了，想要看看啟動起來沒有可以查看進程：
ps -ef | grep eureka
當然，我們也可以在啟動的時候指定某些配置：
指定端口號：
nohup java -jar micro-service/micro-eureka-server-0.0.1-SNAPSHOT.jar --server.port=8888 &
其他的依葫蘆畫瓢…
補充知識：springcloud創(chuàng)建統(tǒng)一配置后不能正常啟動
我就廢話不多說了，大家還是直接看代碼吧~
