  redis:
    addrs:
      - dragonfly-redis
    masterName: your_redis_master_name
    username: your_redis_username
    password: your_redis_passwprd
    db: 0
    brokerDB: 1
    backendDB: 2

Run Manager:

Notice : Run Manager under Dragonfly2

# Setup Manager.
go run cmd/manager/main.go --config /etc/dragonfly/manager.yaml --verbose --console

Verify

After the Manager deployment is complete, run the following commands to verify if Manager is started, and if Port 8080 and 65003 is available.

telnet 127.0.0.1 8080

    brokerDB: 1
    backendDB: 2
    networkTopologyDB: 3
 manager:
  addr: 127.0.0.1:65003
  schedulerClusterID: 1
  keepAlive:
    interval: 5s

Run Scheduler:

  enable: true
  type: super
  clusterID: 1

Run Dfdaemon as Seed Peer:

Notice : Run Dfdaemon under Client

# Setup Dfdaemon.
cargo run --bin dfdaemon -- --config /etc/dragonfly/dfdaemon.yaml -l info --verbose

Verify

After the Seed Peer deployment is complete, run the following commands to verify if Seed Peer is started, and if Port 4000, 4001 and 4002 is available.

telnet 127.0.0.1 4000
telnet 127.0.0.1 4001
