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

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
