启动方式一，直接命令启动，不编辑config.ini
nodeos -p user --plugin eosio::chain_api_plugin --plugin eosio::net_api_plugin --http-server-address 127.0.0.1:8890 --p2p-listen-endpoint 127.0.0.1:9877 --p2p-peer-address p2p.meet.one:9876 --config-dir nodedata --data-dir nodedata --genesis-json genesis.json
这里直接连接p2p.meet.one:9876这个地址，
其他地址列表有
p2p.one.eosdublin.io:9876
eu-west-nl.eosamsterdam.net:9876
p2p.mainnet.eosgermany.online:9876

二、验证是否正常
cleos -u "http://127.0.0.1:8890" get info
chain_id 为aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906
则正常

常见问题：
nodeos关闭重启时，还得删除genesis配置参数，否则出现如下错误：
!fc::exists( my->blocks_dir / “blocks.log” ): Genesis state can only be set on a fresh blockchain
说明配置了genesis.json，但是blocks目录不为空
需要删除blocks或者去除--genesis-json的配置
