### 运行 πflow Server：

- `Intellij上运行PiFlow Server`:   
  - 下载 piflow: git clone https://github.com/cas-bigdatalab/piflow.git
  - 将PiFlow导入到Intellij
  - 编辑配置文件config.properties
  - Build PiFlow jar包:   
    - Run --> Edit Configurations --> Add New Configuration --> Maven  
    - Name: package
    - Command line: clean package -Dmaven.test.skip=true -X  
    - run 'package' (piflow jar file will be built in ../piflow/piflow-server/target/piflow-server-0.9.jar)  
    
  - 运行 HttpService:   
    - Edit Configurations --> Add New Configuration --> Application  
    - Name: HttpService
    - Main class : cn.piflow.api.Main  
    - Environment Variable: SPARK_HOME=/opt/spark-2.2.0-bin-hadoop2.6(change the path to your spark home)  
    - run 'HttpService'
  
  - 测试 HttpService:   
    - 运行样例流水线: ../piflow/piflow-server/src/main/scala/cn/piflow/api/HTTPClientStartMockDataFlow.scala
    - 需要修改API中的server ip 和 port
  
  
- `通过Release版本运行PiFlow`:
  - 根据需求下载最新版本PiFlow:  
    https://github.com/cas-bigdatalab/piflow/releases/download/v1.0/piflow-server-v1.0.tar.gz    
    
  - 解压piflow-server-v1.0.tar.gz:  
    tar -zxvf piflow-server-v1.0.tar.gz
    
  - 编辑配置文件config.properties  
  
  - 运行、停止、重启PiFlow Server  
    start.sh、stop.sh、 restart.sh、 status.sh  
  
  - 测试 PiFlow Server
    - 设置环境变量 PIFLOW_HOME  
      - vim /etc/profile  
        export PIFLOW_HOME=/yourPiflowPath  
      	export PATH=$PATH:$PIFLOW_HOME/bin  
        
      - 运行如下命令   
        piflow flow start example/mockDataFlow.json  
        piflow flow stop appID  
        piflow flow info appID  
        piflow flow log appID  
      
        piflow flowGroup start example/mockDataGroup.json  
        piflow flowGroup stop groupId  
        piflow flowGroup info groupId  
        
- `如何配置config.properties`
     
      #spark and yarn config
      spark.master=yarn
      spark.deploy.mode=cluster
      
      #hdfs default file system
      fs.defaultFS=hdfs://10.0.86.191:9000
      
      #yarn resourcemanager.hostname
      yarn.resourcemanager.hostname=10.0.86.191
      
      #if you want to use hive, set hive metastore uris
      #hive.metastore.uris=thrift://10.0.88.71:9083
      
      #show data in log, set 0 if you do not want to show data in logs
      data.show=10
      
      #server port
      server.port=8002
      
      #h2db port
      h2.port=50002
  
### 运行πFlow Web请到如下链接，πFlow Server 与 πFlow Web版本要对应：
  - https://github.com/cas-bigdatalab/piflow-web/releases/tag/v1.0  
  
  
### 接口Restful API：

- flow json（可查看piflow-bin/example文件夹下的流水线样例）

- CURL方式：
  - curl -0 -X POST http://10.0.86.191:8002/flow/start -H "Content-type: application/json" -d 'this is your flow json'
  
- 命令行方式： 
  - set PIFLOW_HOME  
    vim /etc/profile  
  	export PIFLOW_HOME=/yourPiflowPath/piflow-bin  
    export PATH=\$PATH:\$PIFLOW_HOME/bin

- command example  
    piflow flow start yourFlow.json  
    piflow flow stop appID  
    piflow flow info appID  
    piflow flow log appID

piflow flowGroup start yourFlowGroup.json  
    piflow flowGroup stop groupId  
    piflow flowGroup info groupId  
    
## Docker镜像

- 拉取Docker镜像  
    docker pull registry.cn-hangzhou.aliyuncs.com/cnic_piflow/piflow:v1.1    
    
  - 查看Docker镜像的信息    
    docker images
     
  - 通过镜像Id运行一个Container，所有PiFlow服务会自动运行。请注意设置HOST_IP   
    docker run -h master -itd --env HOST_IP=\*.\*.\*.\* --name piflow-v1.1 -p 6001:6001 -p 6002:6002  [imageID]  
    
  - 访问 "HOST_IP:6001", 启动时间可能有些慢，需要等待几分钟
  
  - if somethings goes wrong,  all the application are in /opt  folder
