一、从GitHub上克隆主网代码仓库：（注意EOS-Mainnet/eos 与 EOSIO/eos 的版本是一致的。若以前在本地已经安装编译过EOSIO/eos的1.0.2版本及以上，则可以直接跳到步骤三），最新版本是1.1.6
git clone https://github.com/EOS-Mainnet/eos
cd eos
git submodule update --init --recursive
git tag
git checkout mainnet-1.1.6二、编译eos代码
./eosio_build.sh 三、替换config.ini 和 genesis.json 文件
（1）运行nodeos节点后会生成默认的config.ini/genesis.json文件，现在对其进行替换
（2）在不同系统中找到其文件地址：
- linux-ubuntu: ~/.local/share/eosio/nodeos/config/
- mac-osx: ~/Library/Application\ Support/eosio/nodeos/config/
（3）新的config.ini文件设置如下：
# fullnode sample config
blocks-dir = "blocks"
chain-state-db-size-mb = 1024
reversible-blocks-db-size-mb = 340
contracts-console = false
https-client-validate-peers = 1
http-server-address = 0.0.0.0:8888
access-control-allow-credentials = false
p2p-listen-endpoint = 0.0.0.0:9876
p2p-server-address = 0.0.0.0:9876
# List of peers
p2p-peer-address = p2p.one.eosdublin.io:9876
p2p-peer-address = eu-west-nl.eosamsterdam.net:9876
p2p-peer-address = p2p.mainnet.eosgermany.online:9876
p2p-peer-address = 35.197.190.234:19878
p2p-peer-address = p2p.genereos.io:9876
p2p-peer-address = fullnode.eoslaomao.com:443
p2p-peer-address = new.eoshenzhen.io:10034
p2p-peer-address = node1.eosphere.io:9876
p2p-peer-address = p2p.meet.one:9876
p2p-peer-address = bp.eosbeijing.one:8080
p2p-peer-address = peer1.mainnet.helloeos.com.cn:80
p2p-peer-address = p2p-public.hkeos.com:19875
p2p-peer-address = pub1.eostheworld.io:9876
p2p-peer-address = eu1.eosdac.io:49876
p2p-peer-address = peer.eosio.sg:9876
p2p-max-nodes-per-host = 10
agent-name = "eosmainnet"
# 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 = 250
connection-cleanup-period = 30
network-version-match = 1
sync-fetch-span = 100
max-implicit-request = 1500
enable-stale-production = false
pause-on-startup = false
max-transaction-time = 10000
max-irreversible-block-age = -1
txn-reference-block-lag = 0
# 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
其中p2p-peer-address的配置来源于：
https://docs.google.com/spreadsheets/d/1K_un5Vak3eDh_b4Wdh43sOersuhs0A76HMCfeQplDOY/edit#gid=0
（4）genesis.json文件内容如下：
{
"initial_timestamp": "2018-06-08T08:08:08.888",
"initial_key": "EOS7EarnUhcyYqmdnPon8rm7mBCTnBoot6o7fE2WzjvEX2TdggbL3",
"initial_configuration": {
"max_block_net_usage": 1048576,
"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,
"max_transaction_lifetime": 3600,
"deferred_trx_expiration_window": 600,
"max_transaction_delay": 3888000,
"max_inline_action_size": 4096,
"max_inline_action_depth": 4,
"max_authority_depth": 6
}
}
此文件称为创世json文件，来自以下链接：
https://github.com/EOS-Mainnet/eos/blob/launch-rc-1.0.2/mainnet-genesis.json
四、将以上的创世json文件，复制拷贝到~/eos/build/program/nodeos目录下，并启动nodeos节点：
./nodeos --genesis-json genesis.json 启动和连接可能不会那么顺利，我是用下面的命令的
./nodeos --data-dir . --config-dir . --genesis-json genesis.json
注意：编译完成后相关的程序都在：/Users/[your name]/eos-mainnet/eos/build/programs/nodeos
五、连接主网查看链信息:
EOS钱包推荐，imtoken，需要找一个已有eos账户的帮忙才可以噢，因为要买cpu和内存
eos一些常用的命令学习：
cleos create key #创建公钥私钥对，用于创建钱包等
cleos get info
cleos get block 191
因为现在主网数据已经很多了，到12325622个block了，所以要同步数据是很慢的，我们直接不同步数据，直连主网
cleos -u https://api.eosnewyork.io get account yiguidyiguid
