EOS 主节点同步

一.从github克隆主网代码仓库

git clone https://github.com/EOSIO/eos --recursive

二.编译与安装EOS环境

cd ~/eos
./eosio_build.sh  

编译成功后会输出如下：

三.设置环境

sudo make install  

四.修改配置文件

1.先运行一次 ./nodeos,报错后会产生文件夹 ~/.local   把下面的config.ini文件替换默认的config.ini文件，文件放在 ~/.local/share/eosio/nodeos/config路径下。

# fullnode sample config  

blocks-dir = "blocks"  

chain-state-db-size-mb =   

reversible-blocks-db-size-mb =   

contracts-console = false  

https-client-validate-peers =   

http-server-address = 0.0.0.0:  

access-control-allow-credentials = false  

p2p-listen-endpoint = 0.0.0.0:  

p2p-server-address = 0.0.0.0:  

# List of peers  

p2p-peer-address = p2p.one.eosdublin.io:  

p2p-peer-address = eu-west-nl.eosamsterdam.net:  

p2p-peer-address = p2p.mainnet.eosgermany.online:  

p2p-peer-address = 35.197.190.234:  

p2p-peer-address = p2p.genereos.io:  

p2p-peer-address = fullnode.eoslaomao.com:  

p2p-peer-address = new.eoshenzhen.io:  

p2p-peer-address = node1.eosphere.io:  

p2p-peer-address = p2p.meet.one:  

p2p-peer-address = bp.eosbeijing.one:  

p2p-peer-address = peer1.mainnet.helloeos.com.cn:  

p2p-peer-address = p2p-public.hkeos.com:  

p2p-peer-address = pub1.eostheworld.io:  

p2p-peer-address = eu1.eosdac.io:  

p2p-peer-address = peer.eosio.sg:  

p2p-max-nodes-per-host =   

agent-name = "kevincaokun1"  

# allowed-connection can be set to "specified" to use whitelisting with the "peer-key" option  

allowed-connection = any  

# peer-private-key is needed if you are whitelisting specific peers with the "peer-key" option  

peer-private-key = ["EOS6qTvpRYx35aLonqUkWAMwAf3mFVugYfQCbjV67zw2aoe7Vx7qd", "5JroNC1B4pz9gJzNZeU7tkU6YMtoeWRCr4CJJwKsVXnJhRbKXSC"]  

max-clients =   

connection-cleanup-period =   

network-version-match =   

sync-fetch-span =   

max-implicit-request =   

enable-stale-production = false  

pause-on-startup = false  

max-transaction-time =   

max-irreversible-block-age = -  

txn-reference-block-lag =   

# Plugins used for full nodes  

plugin = eosio::chain_api_plugin  

plugin = eosio::history_api_plugin  

plugin = eosio::chain_plugin  

plugin = eosio::history_plugin  

plugin = eosio::net_plugin  

plugin = eosio::net_api_plugin

2.创建一个创世json文件genesis.json ，放在 ~/eos/build/program/nodeos路径下，文件内容如下：

{
  "initial_timestamp": "2018-06-08T08:08:08.888",
  "initial_key": "EOS7EarnUhcyYqmdnPon8rm7mBCTnBoot6o7fE2WzjvEX2TdggbL3",
  "initial_configuration": {
    "max_block_net_usage": ,
    "target_block_net_usage_pct": ,
    "max_transaction_net_usage": ,
    "base_per_transaction_net_usage": ,
    "net_usage_leeway": ,
    "context_free_discount_net_usage_num": ,
    "context_free_discount_net_usage_den": ,
    "max_block_cpu_usage": ,
    "target_block_cpu_usage_pct": ,
    "max_transaction_cpu_usage": ,
    "min_transaction_cpu_usage": ,
    "max_transaction_lifetime": ,
    "deferred_trx_expiration_window": ,
    "max_transaction_delay": ,
    "max_inline_action_size": ,
    "max_inline_action_depth": ,
    "max_authority_depth":
  }
}

五.启动nodeos

　　如果使用以前原有的工程，请先清除掉 ~/.local/share/eosio/nodeos/data 文件夹和~/eosio-wallet文件夹，做好准备工作后，启动节点：

cd ~/eos/build/program/nodeos
./nodeos --genesis-json genesis.json

六.查看同步数据

使用命令

cleos get info 

输出如下：

hml@Ulord-19:~/.local/share/eosio/nodeos$ cleos get info
{
  "server_version": "c9b7a247",
  "chain_id": "aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906",
  "head_block_num": 308445,
  "last_irreversible_block_num": 308444,
  "last_irreversible_block_id": "0004b4dcd70b982d37dc2be431ce59c514bb29c6f461449277225dc4aa61956c",
  "head_block_id": "0004b4ddb85592d3625080d80ec1820b06cc3d1a2d11ea4679c16956a6b19ee0",
  "head_block_time": "2018-06-12T05:48:31.500",
  "head_block_producer": "genesisblock",
  "virtual_block_cpu_limit": 200000000,
  "virtual_block_net_limit": 1048576000,
  "block_cpu_limit": 199900,
  "block_net_limit": 1048576
}

　　其中chain_id的值为aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906说明已经设置成功了，还可以获取区块191的信息,输入以下命令：

cleos get block 

会输出以下内容：

发现这个191区块存在这样一笔交易，eosio 账户给 b1账户转了 10个EOS，并且备注了这样一句话：

Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it's the only thing that ever has - eosacknowledgments.io

翻译成中文是：永远不要怀疑一小群有思想、有责任心的公民能改变世界，事实上，这是唯一的事情。
