Running Multiple Nodes On A Machine

Start a seed node

cd $GOPATH/src/github.com/dappley/go-dappley/dapp
./dapp -f conf/seed.conf

Start a peer node

./dapp -f conf/node.conf

Running Mutiple Nodes On Multiple Machines

Start a seed node

1. On your first machine, run ifconfig to find your ip address.

ifconfig

2. Run the following command to start your seed node.

cd $GOPATH/src/github.com/dappley/go-dappley/dapp
./dapp -f conf/seed.conf

Start a peer node

1. On your second machine, first go to your node.conf file

cd $GOPATH/src/github.com/dappley/go-dappley/dapp/conf
vim node.conf

2. Modify the ip address of your seed node. Replace <seed node ip address> with your seed node's ip address that you have found in the previous step

consensusConfig{
    minerAddr: "1ArH9WoB9F7i6qoJiAi7McZMFVQSsBKXZR"
    privKey: "bb23d2ff19f5b16955e8a24dca34dd520980fe3bddca2b3e1b56663f0ec1aa7e"
}

nodeConfig{
    port:   12346
    seed:   "/ip4/<seed node ip address>/tcp/12345/ipfs/QmNzA9rsEcM5nAzX9PzTrabJsGiifzaUU85Qe78HSDzSSE"
    dbPath: "../bin/node.db"
    rpcPort: 50052
}

cd ../
./dapp -f conf/node.conf
