我們的spring cloud微服務一般是打成jar包發布的，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創建統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~
