如何运行Piflow Server
- `使用Intellij Idea`:
- 编辑config.properties文件
- build piflow工程生成piflow-server.jar
- 运行cn.piflow.api.Main
- 切记设置SPARK_HOME
- `直接运行release版本`:
2019-10-23 10:38:25 +08:00
- 下载release版本地址https://github.com/cas-bigdatalab/piflow/releases
2019-03-19 10:34:56 +08:00
- 将build好的piflow-server.jar拷贝到piflow_release文件夹由于git不能上传超过1G大文件故需自行build piflow-server.jar
- 编辑config.properties文件
- 运行start.sh 或者后台运行 nohup ./start.sh > piflow.log 2>&1 &
- `如何配置config.properties`
