Run πFlow Server：

• run piflow server on Intellij:

  • download piflow: git clone https://github.com/cas-bigdatalab/piflow.git

  • import piflow into Intellij

  • edit config.properties file

  • build piflow to generate piflow jar:

    • 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)

  • run 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'

  • test HttpService:

    • run /../piflow/piflow-server/src/main/scala/cn/piflow/api/HTTPClientStartMockDataFlow.scala
    • change the piflow server ip and port to your configure

• run piflow server by release version:

  • download piflow.tar.gz:
    https://github.com/cas-bigdatalab/piflow/releases/download/v1.2/piflow-server-v1.5.tar.gz

  • unzip piflow.tar.gz:
    tar -zxvf piflow.tar.gz

  • edit config.properties

  • run start.sh、stop.sh、 restart.sh、 status.sh

  • test piflow server

    • set PIFLOW_HOME

      • vim /etc/profile
        export PIFLOW_HOME=/yourPiflowPath/bin
        export PATH=$PATH:$PIFLOW_HOME/bin

      • command
        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

• how to configure 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
  
  #If you want to upload python stop,please set hdfs configs
  #example hdfs.cluster=hostname:hostIP
  #hdfs.cluster=master:127.0.0.1
  #hdfs.web.url=master:50070
  

Run πFlow Web：

• Visit address, download the corresponding *.tar.gz file, and modify the corresponding configuration file（The version must be consistent with piflow-server）
  • https://github.com/cas-bigdatalab/piflow-web/releases/tag/v1.5
• If you want to upload python stops, please modify docker.service

  vim /usr/lib/systemd/system/docker.service
  ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
  systemctl daemon-reload
  systemctl restart docker

Restful API：

• flow json

docker-started

• pull piflow images
  docker pull registry.cn-hangzhou.aliyuncs.com/cnic_piflow/piflow:v1.5

• show docker images
  docker images

• run a container with piflow imageID ， all services run automatically. Please Set HOST_IP and some docker configs.
  docker run -h master -itd --env HOST_IP=*.*.*.* --name piflow-v1.5 -p 6001:6001 -v /usr/bin/docker:/usr/bin/docker -v /var/run/docker.sock:/var/run/docker.sock --add-host docker.host:*.*.*.* [imageID]

• please visit "HOST_IP:6001", it may take a while

• if somethings goes wrong, all the application are in /opt folder
