linux - 在服务/流程中将 React + Spring Boot JAR 部署到 AWS EC2 Linux 服务器
问题描述
我有一个完整的堆栈 React.js 和 Spring Boot 应用程序,我正在尝试找出一种将其部署到 AWS EC2 Linux 服务器的好方法,我可以让它 24/7 运行。我的问题是我可以将它作为 AWS EC2 上的可执行 jar 运行,我可以使用我的 Web 浏览器从公共 IP 地址访问它,但是当我关闭终端时它会停止 jar。我可以用什么来将它作为后台服务/进程运行,以便在我关闭终端时它保持在后台运行?Tomcat 似乎只适用于战争文件。
我将它打包为带有嵌入式 tomcat 服务器的 jar 文件,并使用此答案中的 frontend-maven-plugin 将其打包为 jar。
服务器是 Amazon Linux AMI 2018.03.0 (HVM),SSD 卷类型 - ami-01460aa81365561fe

解决方案
你可以像这样运行Linux的后台进程:
java -jar [YOUR JAR FILE NAME] &
该命令末尾的 & 符号告诉 Linux 将 java 作为进程或后台作业运行。
