1.创建文件夹
因为我们本地还搭建了测试网的信息，为了不冲突，所以创建新的文件夹放主网的配置文件和区块数据
mkidr /Users/<Your Name>/Documents/data/EOSData/MainNet
#配置文件路径
mkidr /Users/<Your Name>/Documents/data/EOSData/MainNet/config
#区块数据同步路径
mkidr /Users/<Your Name>/Documents/data/EOSData/MainNet/data
2.修改config.ini配置文件
默认文件路径 /Users/<Your Name>/Library/Application\ Support/eosio/nodeos/config/config.ini
我们就不修改默认的文件路径，我们新建一个文件在上面的文件夹里面
/Users/<Your Name>/Documents/data/EOSData/MainNet/config
CryptoLions提供了主网的配置文件config.ini给大家参考

3.新建主网的创世文件genesis.json
在config.ini文件旁边建立一个genesis.json文件，然后nodeos启动的时候指定路径
CryptoLions也提供了主网的创世文件genesis.json给大家参考
https://github.com/CryptoLions/EOS-MainNet/blob/master/genesis.json

"max_inline_action_depth": 4,
"max_authority_depth": 6
}
}
4.启动节点
--config-dir指定配置文件夹的路径 --data-dir 指定同步数据的路径
第一次启动节点时最好时清空所有区块数据，添加参数 --delete-all-blocks，第二次启动不需要，不然每次都要重新同步一次的数据
./nodeos --config-dir /Users/<Your Name>/Documents/data/EOSData/MainNet/config --data-dir /Users/<Your Name>/Documents/data/EOSData/MainNet/data --genesis-json /Users/<Your Name>/Documents/data/EOSData/MainNet/config/mainnet-genesis.json --delete-all-blocks
4.检查是否正常
./cleos get info
{
"server_version": "7d210b38",
"chain_id": "aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906",

"last_irreversible_block_id": "0000055d0a89de53b028bb49c8ca335d32d6aafe1dcff7508c7df27a196255d3",

}
看到 "chain_id": "aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906",代表以及连接到主网，等待head_block_num和主网最新去看号一致就说明同步完成
