這篇文章主要介紹了解決spring cloud服務(wù)啟動(dòng)之后回到命令行會(huì)自動(dòng)掛掉問(wèn)題，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。一起跟隨小編過(guò)來(lái)看看吧
我們的spring cloud微服務(wù)一般是打成jar包發(fā)布的，Linux下啟動(dòng)jar包和windows下一樣，都是java -jar 包名，實(shí)際操作過(guò)的小伙伴可能會(huì)遇到這種情況：用java -jar啟動(dòng)之后，再切回到命令行服務(wù)會(huì)掛掉，怎么解決呢？使用nohup命令就不會(huì)了！
例：
jar包：
micro-service/micro-eureka-server-0.0.1-SNAPSHOT.jar
啟動(dòng)命令：
ohup java -jar micro-service/micro-eureka-server-0.0.1-SNAPSHOT.jar &
啟動(dòng)之后用 ctrl+c 回到命令行就不會(huì)掛掉了，想要看看啟動(dòng)起來(lái)沒(méi)有可以查看進(jìn)程：
ps -ef | grep eureka
當(dāng)然，我們也可以在啟動(dòng)的時(shí)候指定某些配置：
指定端口號(hào)：
nohup java -jar micro-service/micro-eureka-server-0.0.1-SNAPSHOT.jar --server.port=8888 &
其他的依葫蘆畫(huà)瓢…
補(bǔ)充知識(shí)：springcloud創(chuàng)建統(tǒng)一配置后不能正常啟動(dòng)
我就廢話不多說(shuō)了，大家還是直接看代碼吧~
