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：
