设置仓库

Settings -> Actions -> Runners -> New self-hosted runner

  • Runner image: Linux
  • Architecture: x64

Register Runner 

./config.sh --name <name> --url <repo_url> --token <token>
## 后台运行并输出日志到run.log
./run.sh > run.log 2>&1 &

测试Github workflow

  • 创建.github/workflows/ci.yaml
  • 注: runs-on: self-hosted
