一、從github克隆主網程式碼倉庫：

git clone https://github.com/EOS-Mainnet/eos

二、更新程式碼倉庫子模組，使用遞迴引數

git submodule update --init --recursive

三、git tag命令檢視版本標籤

git tag

四、git checkout mainnet-1.0.2.2本地倉庫程式碼切換到mainnet-1.0.2.2版本

git checkout mainnet-1.0.2.2

五、git branch 檢視本地倉庫程式碼版本是否mainnet-1.0.2.2

git branch

六、執行自動化編譯指令碼：./eosio_build.sh，對程式碼進行編譯

./eosio_build.sh

自動化編譯過程可能會因為主機實體記憶體小於7G，boost庫，mongodb等下載失敗或其他原因而編譯失敗，請查詢原因或修改指令碼自行解決。

七、為了後續操作方便，可以安裝一下，省的每次啟動nodeos或敲cleos命令列都要切換目錄

sudo make install

八、config.ini檔案內容如下

# 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 = "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 = 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
 

九、創世json檔案genesis.json 內容如下：

{
  "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
  }
}
 

十、config.ini和genesis.json檔案放置路徑

linux-ubuntu:  ~/.local/share/eosio/nodeos/config/

mac-osx:  ~/Library/Application\ Support/eosio/nodeos/data/config

十一、啟動nodeos前注意：清理舊的資料

十二、nodeos啟動後使用 cleos get info 命令檢視鏈的chain_id 是否下面這行程式碼：

aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906

 cleos get info

十三、注意如果chain_id不對，則不是主網的鏈，不會從主網同步資料，遇到這種情況請使用下面命令重新啟動nodeos,注意路徑和你主機上nodeos 所在的路徑一致，並且把genesis.json檔案拷貝到該目錄下面

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

十四、區塊資料正常同步以後，可以使用cleos命令列對鏈條進行一些操作，比如：檢視191塊的資料

cleos get block 191

發現這個191區塊存在這樣一筆交易，eosio 賬戶給 b1賬戶轉了 10個EOS，並且備註了這樣一句話：

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

翻譯成中文是：永遠不要懷疑一小群有思想、有責任心的公民能改變世界，事實上，這是唯一的事情。
