EOS全节点连接主网

下载主网 genesis.json ，地址:https://github.com/EOS-Mainnet/eos/blob/launch-rc-1.0.2/mainnet-genesis.json

vim genesis.json

{
  "initial_timestamp": "2018-06-08T08:08:08.888",
  "initial_key": "EOS7EarnUhcyYqmdnPon8rm7mBCTnBoot6o7fE2WzjvEX2TdggbL3",
  "initial_configuration": {

    "target_block_net_usage_pct": 1000,
    "max_transaction_net_usage": 524288,
    "base_per_transaction_net_usage": 12,
    "net_usage_leeway": 500,
    "context_free_discount_net_usage_num": 20,
    "context_free_discount_net_usage_den": 100,
    "max_block_cpu_usage": 200000,
    "target_block_cpu_usage_pct": 1000,
    "max_transaction_cpu_usage": 150000,
    "min_transaction_cpu_usage": 100,

}

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

p2p.genereos.io:9876

fullnode.eoslaomao.com:443

 new.eoshenzhen.io:10034

node1.eosphere.io:9876

 p2p.meet.one:9876

 bp.eosbeijing.one:8080

 peer1.mainnet.helloeos.com.cn:80

二、验证是否正常

cleos -u "http://127.0.0.1:8890" get info

chain_id 为aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906
则正常

{
  "server_version": "c9b7a247",
  "chain_id": "aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906",
  "head_block_num": 1,

  "virtual_block_net_limit": 1048576,
  "block_cpu_limit": 199900,
  "block_net_limit": 1048576
}

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
