Install it separately by module

Download the precompiled binaries

1. Download a binary package. You can download one of the latest builds for Dragonfly on the github releases page

   Note: v2.x-rc.x rc indicates the candidate version and is not recommended to be deployed in a production environment

   version=2.0.2
   
   wget -O dragonfly_linux_amd64.tar.gz \
      https://github.com/dragonflyoss/Dragonfly2/releases/download/v${version}/dragonfly-${version}-linux-amd64.tar.gz

2. Unzip the package.

   # Replace `/path/to/dragonfly` with the installation directory.
   tar -zxf dragonfly_linux_amd64.tar.gz -C /path/to/dragonfly

3. Configuration environment

   export PATH="/path/to/dragonfly:$PATH"

Build executable file by source code

1. Obtain the source code of Dragonfly.

   git clone --recurse-submodules https://github.com/dragonflyoss/Dragonfly2.git

2. Enter the project directory.

   cd Dragonfly2

3. Compile the source code.

   # At the same time to build scheduler, dfget and manager
   make build
   
   # Equal
   make build-scheduler && make build-dfget && make build-manager
   
   # Install executable file to  /opt/dragonfly/bin/{manager,scheduler,dfget}
   make install-manager
   make install-scheduler
   make install-dfget

4. Configuration environment

   export PATH="/opt/dragonfly/bin/:$PATH"

Operation

Manager

Startup Manager

Configure manager yaml file, The default path for the manager yaml configuration file is /etc/dragonfly/manager.yaml in linux, and the default path is $HOME/.dragonfly/config/manager.yaml in darwin. Please refer to Configure Manager YAML File

# Configure manager yaml file
# Notice: check and modify some config e.g. database.mysql

# View manager cli help docs
manager --help

# startup manager
manager

After manager is installed, run the following commands to verify if manager is started, and if Port 8080 and 65003 is available.

telnet 127.0.0.1 8080
telnet 127.0.0.1 65003

Manager Console

Now you can open brower and visit console by localhost:8080.

Console features preview reference document console preview。

Scheduler

Startup scheduler

Configure scheduler yaml file, The default path for the scheduler yaml configuration file is /etc/dragonfly/scheduler.yaml in linux, and the default path is $HOME/.dragonfly/config/scheduler.yaml in darwin. Please refer to Configure Scheduler YAML File

# Configure scheduler yaml file
# Notice: check and modify some config e.g. job.enable,job.redis,manager.addr ...

# View scheduler cli help docs
scheduler --help

# Startup scheduler
scheduler

After scheduler is installed, run the following commands to verify if scheduler is started, and if Port 8002 is available.

telnet 127.0.0.1 8002

Dfdaemon

Startup dfdaemon as seed peer

Configure dfdaemon's seed peer yaml file, The default path for the dfdaemon yaml configuration file is /etc/dragonfly/dfget.yaml in linux, and the default path is $HOME/.dragonfly/config/dfget.yaml in darwin. Please refer to Configure Dfdaemon YAML File

Configure dfdaemon's yaml file to enable seed peer mode:

# Seed peer yaml file
scheduler:
  manager:
    # get scheduler list dynamically from manager
    enable: true
    # manager service address
    netAddrs:
      - type: tcp
        addr: manager-service:65003
    # scheduler list refresh interval
    refreshInterval: 10s
    seedPeer:
      enable: true
      type: 'super'
      clusterID: 1

Run dfdaemon as seed peer.

# Configure dfdaemon yaml file
# Notice: check and modify some config e.g. scheduler.manager ...

# View dfget cli help docs
dfget --help

# View dfget daemon cli help docs
dfget daemon --help

# Startup dfget daemon mode
dfget daemon

Startup dfdaemon as peer

Configure dfdaemon's peer yaml file, The default path for the dfdaemon yaml configuration file is /etc/dragonfly/dfget.yaml in linux, and the default path is $HOME/.dragonfly/config/dfget.yaml in darwin. Please refer to Configure Dfdaemon YAML File

# Configure dfdaemon yaml file
# Notice: check and modify some config e.g. scheduler.manager ...

# View dfget cli help docs
dfget --help

# View dfget daemon cli help docs
dfget daemon --help

# Startup dfget daemon mode
dfget daemon

After dfget is installed, run the following commands to verify if dfdaemon is started, and if Port 65000, 65001 and 65002 is available.

telnet 127.0.0.1 65000
telnet 127.0.0.1 65001
