升级系统
sudo apt update && sudo apt upgrade -y
接着安装
sudo apt install curl tar wget clang pkg-config libssl-dev jq build-essential git make ncdu -y
安装go
ver="1.18.2"
cd $HOME
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm "go$ver.linux-amd64.tar.gz"
添加环境
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile
检查go版本
go version
go安装成功，如下所示(此为输出信息，无需复制）
go version go1.18.2 linux/amd64
下载并安装celestia
cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node/
git checkout tags/v0.3.0-rc2

实例化一个轻节点
celestia light init
创建钱包
make cel-key
创建钱包第二步
./cel-key add developer --keyring-backend test --node.type light
成功后会输出一下开头类似信息（每个人地址不一样）
- address: celestia1mupdr4qu8wh57s467ewj6vk3mqlxrp0nagpr45
设置守护进程
sudo tee <<EOF >/dev/null /etc/systemd/system/celestia-lightd.service

查看是否设置内容
cat /etc/systemd/system/celestia-lightd.service
启动守护进程
systemctl enable celestia-lightd
systemctl start celestia-lightd
检查守护进程状态
systemctl status celestia-lightd
换一个ssh窗口查看日志内容
journalctl -u celestia-lightd.service -f
可以去discord的#faucet 输入以下信息(地址替换成你自己的)

本文只对守护进程设置做了一点改动。利用screen也可以实现后台运行节点。
