以太坊swarm初学

安装过程

• 安装环境基于ubuntu 18.04 LTS amd_64

• 安装bee clief
  这种安装方式是安装一个在Bee Node里集成了集成了Go-Ethereum Clef signer实例的节点。我们可以选择只装Bee或者Bee Clief, 初学者适合安装Bee clief。
  Bee Node是一个基于以太坊2.0 SWARM存储协议的节点，文章在这里https://docs.ethswarm.org/docs/

    安装：wget https://github.com/ethersphere/bee-clef/releases/download/v0.4.9/bee-clef_0.4.9_amd64.deb
          sudo dpkg -i bee-clef_0.4.9_amd64.deb
  

• 检查状态
  systemctl status bee-clef
  lyp@lyp-ThinkPad-E550:~/ethereum$ systemctl status bee-clef

   	wget https://github.com/ethersphere/bee/releases/download/v0.5.3/bee_0.5.3_amd64.deb
   	sudo dpkg -i bee_0.5.3_amd64.deb
  

• 备份数据

    	systemctl stop bee
    	sudo chown -R bee:bee /var/lib/bee/statestore
   		    
   	#cd /var/lib/bee
   	#cp -rf bee-clef  bee-clef_lyp_bak_from_var_lib_bee
   	#cp -rf bee   bee_lyp_bak_from_var_lib_bee
   	cp -rf /var/lib/bee ~/
  

• 启动bee

   	systemctl start bee
  

• 查看CLEF日志

     	 journalctl -f -u bee-clef.service
