如何加入VNT Hubble主网

环境：Ubuntu20.04

（但以下方法应该只要不是过于老旧的Ubuntu，都行得通）

从源码安装go-vnt

安装Go编译器（版本大于1.9）和C编译器

• 安装C编译器GCC^[1]

  sudo apt-get  build-dep  gcc
  

  验证GCC是否安装成功

  gcc --version
  

  如果出现GCC版本信息，说明安装成功。

  

• 安装go编译器^[1]

  • 下载go编译器（编译器版本大于1.9，我们这里是1.10）

    wget https://storage.googleapis.com/golang/go1.10.linux-amd64.tar.gz
    

  • 解压压缩包到/usr/local下面

    sudo tar -C /usr/local -xzf go1.10.linux-amd64.tar.gz
    

  • 配置环境变量

    • 在$HOME/.bashrc文件的末尾添加三行

      vim $HOME/.bashrc
      

      （不会vim可用gedit命令）

      export GOROOT=/usr/local/go
      export GOPATH=$HOME/go
      export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
      

    • 更新文件，使文件生效

      source ~/.bashrc
      

  • 输入命令，查看GO编译器版本信息

    go version
    

    如果显示版本信息，则说明安装成功

    

克隆go-vnt源码^[2]

• 首先，克隆仓库go-vnt到路径$GOPATH/src/github.com/vntchain，并进入项目目录:

  mkdir -p $GOPATH/src/github.com/vntchain
  cd $GOPATH/src/github.com/vntchain
  git clone https://github.com/vntchain/go-vnt
  cd go-vnt
  

  如果有以前的版本，请更新到最新：

  git pull
  

• 然后，使用下面命令编译gvnt:

  make gvnt
  

  或者使用下面命令编译gvnt和所有工具:

  make all
  

  经过以上可以在$GOPATH/src/github.com/vntchain/go-vnt/build/bin/目录调用gvnt，为方便使用可以将gvnt安装到$GOPATH/bin:

  go install -v ./cmd/gvnt
  

• 查看当前使用的gvnt版本号

  gvnt version
  

  

创建并进入节点目录^[3]

cd ~
mkdir vntnode
cd vntnode

使用init.json文件初始化节点

init.json文件内容如下：

}

创建init.json文件，并写入以上内容。然后使用init.json进行初始化：（注意命令后面的“."表示当前目录，不要漏了）

gvnt init init.json --datadir .

创建账号

可以设置密码：

gvnt account new .

如果你已经有账号，可以直接将账号keystore文件拷贝到vntnode/keystore目录。

启动节点

使用任一公共全节点的p2p地址作为bootnode，启动节点：

gvnt --networkid 1 --datadir . --port 3001 --vntbootnode "/ip4/39.97.235.82/tcp/3001/ipfs/1kHaSHxTJGAWKgk69Dk4a3BZzzJvVMfzsDHehyJDgm4tXQ8" --syncmode full --rpc --rpcaddr 0.0.0.0 --rpcport 8880 --rpcapi="db,core,net,vnt,personal" console

成功执行以上命令，你应当已经连接上了VNT Hubble主网，并且开始同步区块，区块同步可采用以下方法查看：

通过attach命令连接到节点：

$ cd vntnode
$ gvnt attach gvnt.ipc

查看同步：
