Example-GithubAction

一个小Demo，通过使用Github的自动化CICD服务，部署运行SpringBoot项目在私人服务器上

环境准备

• 一台拥有公共IP的1核1G以上配置的Linux云服务器。笔者选用的Linux发行版为CentOS Linux release 7.0.1406 (Core)
• 已安装好JDK8与Maven。若是还未安装，可以参考以下笔者的安装方式。
  • 软件安装-Java - DiiD - 博客园 (cnblogs.com)
  • 软件安装-Maven - DiiD - 博客园 (cnblogs.com)

项目设置

Github Setting

进入Github仓库管理界面，依次点击Setting->New Repository Sectet 。分别解释以下的字段和值

• HOST：私有服务器公网IP地址
• USERNAME:私有服务器公网用户名，笔者选择root
• PASSWORD:私有服务器USERNAME对应密码
• PORT:私有服务器公网端口，一般取22

Project Setting

在项目的根目录下新增/.github/workflows/maven.yml

并在maven.yml添加以下内容.

# This workflow will build a Java project with Maven, and cache/restore any dependencies to improve the workflow execution time
# For more information see: https://docs.github.com/en/actions/automating-builds-and-tests/building-and-testing-java-with-maven

# This workflow uses actions that are not certified by GitHub.
# They are provided by a third-party and are governed by
# separate terms of service, privacy policy, and support
# documentation.

            pwd

问题与解决

1问题. runtime.log日志显示

nohup: 无法运行命令“java“: 没有那个文件或目录  

1原因：无法识别$$JAVAHOME$的环境变量

1解决：用绝对路径/usr/local/java/jdk1.8.0_361/bin/java即可
