# What is gvite node?

In Vite network, nodes are categorized into full nodes and supernodes. Supernode is special full nodes for producing snapshot blocks. This document mainly introduces full node.

Full node is responsible for maintaining a complete copy of ledger, sending or receiving transactions, and verifying all transactions in the network. Full node can also participate in SBP election and voting. Full node exposes HTTP/WEBSOCKET APIs externally and has a command line console at local.

# Installation example on windows

Open up your preferred browser and paste in the following link:

https://github.com/vitelabs/go-vite/releases/download/v2.8.0/gvite-v2.8.0-windows.tar.gz

and save file to preferred directory. Upon download completion, open up explorer, navigate to the directory where file is downloaded to, right click file and select extract file option.

Extracted destination should contain three files:

gvite-windows-386.exe (32bit executable) gvite-windows-amd64.exe (64bit executable) node_config.json (node config file).

The folder contains the command .exe files and can be used without installing.

Configure node_config.json prior to launching executable (use the 32bit executable if you have a 32bit CPU or 64bit executable if you have a 64bit CPU).

To launch node, simply open up command prompt (by pressing Win + R, then, type cmd and press Enter or click/tap OK.)

Then in command prompt:

C:\Users\user>d:
D:\>cd gvite-v2.8.0-windows
D:\gvite-v2.8.0-windows>gvite-windows-amd64.exe (or your preferred executable)

The following messages indicate boot is successful.

Start the Node success!!!

# Description of installation directory

Installation Directory：Refers to the folder where gvite boot script and configuration file are located. For example, ~/gvite-${version}-${os} is an installation directory.

  • gvite ： Gvite executable file
  • bootstrap ： Boot script
  • node_config.json ： Configuration file. See Configuration Description

# Ports

The default ports are 8483/8484. If you choose to go with default ports, please ensure that they are not occupied by other programs or blocked by firewall.

 netstat -nlp|grep 8483

Check if the default ports are occupied. Gvite will display the following messages if it boots up successfully.

netstat -nlp|grep 8483

# Install from source

# Golang environment check

go env

WARNING

Go 1.11.1 or above version is required. See Go Installation Guide.

# Compile source code

Pull gvite source code

  go get github.com/vitelabs/go-vite

and will be downloaded at:

$GOPATH/src/github.com/vitelabs/go-vite/

The system default GOPATH is ~/go

Go to the source code directory and run

make gvite

Executable file is generated at:

$GOPATH/src/github.com/vitelabs/go-vite/build/cmd/gvite/gvite

# Configuration file

node_config.json is gvite configuration file. It should reside in the same directory with gvite executables. Details can be found at: Config Description

# Boot script

Taking Linux as example, the script has the following content:

nohup ./gvite -pprof >> gvite.log 2>&1 &

# Monitoring

# Query snapshot block height in command line

  • Start a full node as instructed above

  • Connect to gvite command line console: Navigate to Full Node Installation Directory and execute the following command

    Linux/Unix:

    ./gvite attach ~/.gvite/maindata/gvite.ipc

    Windows:

    gvite-windows-amd64.exe attach \\.\pipe\gvite.ipc

    Then execute command:

    vite.ledger_getSnapshotChainHeight();

    The following result will be displayed:

    "{\"id\":0,\"jsonrpc\":\"2.0\",\"result\":\"2166918\"}"

    2166918 is current block height.

  • For more information please run command vite.help .

# Full node rewards

In Vite Pre-Mainnet, rewards will be distributed to full node owners as incentives.

# Node configuration

Additional settings in node_config.json are required:

  • Set full node stats URL: "DashboardTargetURL": "wss://stats.vite.net"
  • Add "dashboard" to PublicModules
  • Set "RewardAddr": "${your_address}" to receive full node reward

The modified part of node_config.json is as below(please note this is not the full config file):

  "PublicModules": [
    "ledger",
    "public_onroad",
    "net",
    "contract",
    "pledge",
    "register",
    "vote",
    "mintage",
    "consensusGroup",
    "tx",
    "dashboard"  // new add
  ],
  "DashboardTargetURL":"wss://stats.vite.net",  // new add
  "RewardAddr":"vite_youraddress"   // new add

# Node status check

Reboot full node, then visit Full Node Stats to examine if your node has shown up correctly (result will reflect in 5 minutes).
