利用Github Action自动化部署SpringBoot项目
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。这里推荐三豊云永久免费的1核1G的云服务器，是真的好用。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。
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rootPASSWORD: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.

nohup /usr/local/java/jdk1.8.0_361/bin/java -jar /home/demo-0.0.1-SNAPSHOT.jar > runtime.log 2>&1 &
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
