基于EOS最新源代码搭建自己的多节点私链

 

 

                              基于EOS最新源代码搭建自己的多节点链

 

（注：1.本文操作前提是EOS(最新版v1.7.3)代码编译正常（参加本人另一篇编译文章），有一定EOS基础 ; 2. 开发环境 VMware WS 12+ ubuntu 16.04  ;3.以下操作需要根据具体情况 变通处理！！）

 

 

 

一 .准备

 

 

1. eosio账户公钥写死在代码中， 在代码根目录 CMakeList.txt里面，找到 EOSIO_ROOT_KEY，改为自己创建的公钥。并把新的密钥对 要在 config.ini文件中保存，见文件中 “signature-provider = 。。。”。

 

  2.编译，安装，参加本人另一篇EOS编译文章。

 

二 .配置文件

 

    1.建议在 nodeos 程序运行目录创建 config文件夹，保存配置文件；同时创建 data文件夹 ，保存区块文件.

 

 

    2.搭建4个独立IP 的 节点（同一局域网），命名为：eosio, node1,node2,node3。所有节点的 genesis.json文件一样，否则不是一个网络，不能通信。

 

 

 

    3.genesis.json 文件内容，如下：
{
  "initial_timestamp": "2018-06-08T08:08:08.888",
  "initial_key": "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV",  #####必须是 eosio 节点 的 公钥
  "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
  }
} 

    4.eosio 节点的 config.ini文件

block-log-dir = "blocks"
shared-memory-size-mb = 1024
http-server-address = 127.0.0.1:8888
access-control-allow-credentials = false
p2p-listen-endpoint = 0.0.0.0:9876

p2p-peer-address = 192.168.8.109:9876
p2p-peer-address = 192.168.8.52:9876
p2p-peer-address = 192.168.8.216:9876

agent-name = "SQU chain"
allowed-connection = any
max-clients = 25
connection-cleanup-period = 30
network-version-match = 0
sync-fetch-span = 100
max-implicit-request = 1500
enable-stale-production = true  ## 只是eosio节点 为true
max-transaction-time = 1000
required-participation = 33
producer-name = eosio      ## 注意节点账户名称，下面是 账户的 keys
signature-provider = 

EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

wallet-dir = "."
unlock-timeout = 90000
plugin = eosio::chain_api_plugin
plugin = eosio::chain_plugin
plugin = eosio::producer_plugin
plugin = eosio::http_plugin
plugin = eosio::history_api_plugin

 

    5.node1,node2,node3 节点的 config.ini 文件类似，只需修改备注的地方

block-log-dir = "blocks"
shared-memory-size-mb = 1024
http-server-address = 127.0.0.1:8888
access-control-allow-credentials = false
p2p-listen-endpoint = 0.0.0.0:9876

p2p-peer-address = 192.168.8.215:9876          ##其他节点的 p2p 地址及端口，不要填写本节点的IP！
p2p-peer-address = 192.168.8.216:9876
p2p-peer-address = 192.168.8.52:9876

agent-name = "SQU chain"
allowed-connection = any
max-clients = 25
connection-cleanup-period = 30
network-version-match = 0
sync-fetch-span = 100
max-implicit-request = 1500

max-transaction-time = 30
required-participation = 33
producer-name = node1             ## 设置本节点账户名称，下面是 该账户的 keys ，根据自己的去修改！！          

signature-provider = EOS6AzQmSAXHH8Mn7pi6B7zZ9UcVfmS5tcVS681bjz5ZvkGPXzGto=KEY:5HxfD1WGTBeVpMvobBDvpd9qLGn8VhLds14GwRaK6zq51XgNvF9

txn-reference-block-lag = 0
wallet-dir = "."
unlock-timeout = 90000
plugin = eosio::chain_api_plugin
plugin = eosio::chain_plugin
plugin = eosio::producer_plugin
plugin = eosio::http_plugin
plugin = eosio::history_api_plugin

 

 

 

三 .创建与发行代币

 

    1.启动四个节点nodeos程序
    (把 config.ini, genesis.json文件放到 config 目录， 区块文件放在 data目录)
     命令如下：
     nodeos  --data-dir ./data --config-dir ./config  --genesis-json  ./config/genesis.json

 

    2.在 eosio 节点上创建钱包 squwallet ，并导入eosio账户私钥
     cleos wallet import -n squwallet   --private-key  5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

 

    3.创建发布token的帐号eosio.token （需自己去创建 key，并把私钥导入到钱包）
    cleos create account eosio eosio.token  EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV    EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

 

    4.发布eosio.token合约 （在eosio.contracts 代码编译后的 build/下面执行）
    gavin@ubuntu:~/eosio.contracts/build$ pwd  (当前目录)
/home/gavin/eosio.contracts/build
gavin@ubuntu:~/eosio.contracts/build$ ls contracts   (子目录)
CMakeCache.txt  CMakeFiles  cmake_install.cmake  eosio.bios  eosio.msig  eosio.system  eosio.token  eosio.wrap  Makefile
gavin@ubuntu:~/eosio.contracts/build$ ls contracts/eosio.token/
CMakeFiles  cmake_install.cmake  eosio.token.abi  eosio.token.wasm  Makefile
gavin@ubuntu:~/eosio.contracts/build$

在build目录下执行 cleos set contract eosio.token ./contracts/eosio.token --abi eosio.token.abi -p ：

gavin@ubuntu:~/eosio.contracts/build$ cleos set contract eosio.token ./contracts/eosio.token --abi eosio.token.abi -p eosio.token@active

gavin@ubuntu:~/eosio.contracts/build$
gavin@ubuntu:~/eosio.contracts/build$

 

    5.创建代币
    gavin@ubuntu:~$ cleos push action eosio.token create '[ "eosio", "1000000000.0000 SYS"]' -p eosio.token@active
executed transaction: 353ba8ee7deb942db70c3029ed464d40de3b75aa312de2c99ec9f3dfca8c5391  120 bytes  195 us
#   eosio.token <= eosio.token::create          {"issuer":"eosio","maximum_supply":"1000000000.0000 SYS"}
warning: transaction executed locally, but may not be confirmed by the network yet         ]
gavin@ubuntu:~$

  6.发行代币

gavin@ubuntu:~$ cleos  push action eosio.token issue '["eosio","1000000000.0000 SYS","issue"]' -p eosio@active
executed transaction: f778aa8a2ee27a7a9e0bc53515e47cf6787149bd6dddef7947ffa0e0e7960269  128 bytes  202 us
#   eosio.token <= eosio.token::issue           {"to":"eosio","quantity":"1000000000.0000 SYS","memo":"issue"}
warning: transaction executed locally, but may not be confirmed by the network yet         ]
gavin@ubuntu:~$

用命令查看 eosio 账户代币：
gavin@ubuntu:~$ cleos get currency balance eosio.token eosio SYS
1000000000.0000 SYS
gavin@ubuntu:~$

 

四 .发布 eosio.system合约

 

    1.创建下面系统账户（共用一套公钥，实际情况 最好使用不同key，并把key导入到钱包）
cleos create account eosio eosio.bpay EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt  EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt
cleos create account eosio eosio.msig EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt  EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt
cleos create account eosio eosio.name EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt  EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt
cleos create account eosio eosio.names EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt  EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt
cleos create account eosio eosio.ram EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt  EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt
cleos create account eosio eosio.ramfee EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt  EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt
cleos create account eosio eosio.saving EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt  EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt
cleos create account eosio eosio.stake EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt  EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt
cleos create account eosio eosio.upay EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt  EOS5jh1BaxfnQhYwJqg7P2CYpyNp2gw9mdctprVpnFCKUqBJU3zEt
 

 

    2.设置eosio.msig合约　（同样在eosio.contracts /build目录下运行）

 

       msig合约支持并简化了权限级别的定义和管理以及执行多重签名操作。
      cleos set contract eosio.msig  ./contracts/eosio.msig/

 

    3.部署eosio.system合约(必须先执行上面的 “创建下面系统账户”)
    该合约为几乎所有基于令牌的操作行为提供了操作。在安装系统合同之前，操作是独立于会计完成的。
    一旦系统合同启用，行动现在对他们有一个经济因素。资源（cpu，网络，内存）必须付费。同样，必须支付新帐户。
    系统合同使得令牌能够被放置和不被冻结，被购买的资源，可能的生产者被注册并且随后被投票，生产者奖励被要求，被设置   的特权和限制等等。
    cleos set contract eosio ./contracts/eosio.system/

新版EOS　system合约，还必须执行下面命令初始化！
gavin@ubuntu:~/eosio.contracts/build$ cleos push action eosio init '[0, "4,SYS"]' -p eosio@active
executed transaction: dc6e2008c21b3b6fdcb78fa236c3ff94e7dcf55723e625115ad1457799ebdb24  104 bytes  409 us
#         eosio <= eosio::init                  {"version":0,"core":"4,SYS"}
#   eosio.token <= eosio.token::open            {"owner":"eosio.rex","symbol":"4,SYS","ram_payer":"eosio"}
warning: transaction executed locally, but may not be confirmed by the network yet         ]
gavin@ubuntu:~/eosio.contracts/build$

    4.在安装eosio.system合同后，我们希望尽快将eosio.msig设置为特权帐户，以便它可以代表eosio帐户进行授权。很快eosio将辞职，eosio.prods将接管。
  使eosio.msig成为一个特权帐户。我们使用以下方法使eosio.msig有特权。
   cleos  push action eosio setpriv '["eosio.msig", 1]' -p eosio@active

 

五 .注册BP及投票

 

    1.用下面这个命令创建投票账户：

     部署了eosio.system合约之后，cleos create account这个命令就不能创建账户了。

     为 node1,node2,node3 准备不同的 key, 并导入钱包。 然后创建各个出块节点的 账户：node1,node2,node3。

    cleos system newaccount eosio node1　EOS6AzQmSAXHH8Mn7pi6B7zZ9UcVfmS5tcVS681bjz5ZvkGPXzGto EOS6AzQmSAXHH8Mn7pi6B7zZ9UcVfmS5tcVS681bjz5ZvkGPXzGto --stake-net '50.00 SWC' --stake-cpu '50.00 SWC' --buy-ram-kbytes 8
    cleos system newaccount eosio node2　EOS5VgmxPRhvsTChoxc9b1NT6zFNhLVLfPpGcjWJUvmoke8dMVeLh EOS5VgmxPRhvsTChoxc9b1NT6zFNhLVLfPpGcjWJUvmoke8dMVeLh  --stake-net '50.00 SWC' --stake-cpu '50.00 SWC' --buy-ram-kbytes 8
    cleos system newaccount eosio node3　EOS7fEc1C6A8QHrK6kjFFFUmGrAmQoyivbrYaAdspKzA6io1gi5ax EOS7fEc1C6A8QHrK6kjFFFUmGrAmQoyivbrYaAdspKzA6io1gi5ax  --stake-net '50.00 SWC' --stake-cpu '50.00 SWC' --buy-ram-kbytes 8

 

    2.将所有需要出块的节点（配置文件中 producer-name = nodeｘ）注册成bp
    cleos  system regproducer node1　EOS6AzQmSAXHH8Mn7pi6B7zZ9UcVfmS5tcVS681bjz5ZvkGPXzGto http://http-server-address:8888
    cleos  system regproducer node2　EOS5VgmxPRhvsTChoxc9b1NT6zFNhLVLfPpGcjWJUvmoke8dMVeLh  http://http-server-address:8888
    cleos  system regproducer node3 EOS7fEc1C6A8QHrK6kjFFFUmGrAmQoyivbrYaAdspKzA6io1gi5ax  http://http-server-address:8888

 

 

    3.给创建的账户转账
    cleos  push action eosio.token transfer '["eosio", "node1","100000000.0000 SYS","vote"]' -p eosio
    cleos  push action eosio.token transfer '["eosio", "node2","100000000.0000  SYS","vote"]' -p eosio
    cleos  push action eosio.token transfer '["eosio", "node3","100000000.0000 SYS","vote"]' -p eosio

 

    4.锁定代币
    cleos system delegatebw node1　node1　'25000000.0000 SYS'　'25000000.0000 SYS'
    cleos system delegatebw node2　node2　'25000000.0000 SYS'　'25000000.0000 SYS'
    cleos system delegatebw node3 　node3 　'25000000.0000 SYS'　'25000000.0000 SYS'

    5.给出块节点投票

    给 节点投票如下
    cleos system voteproducer prods  node1　node1　node2　node3
   cleos system voteproducer prods  node2　node1　node2　node3 

　cleos system voteproducer prods  node3 　node1　node2　node3 　　

注意 ：发行的tonken总量为10亿，按照要求需要至少15%的投票主网才算成功，也即1.5亿的token投票，才能轮流出块，否则还是eosio节点继续出块。

投票后，过一段时间，可以看到 节点node1　node2　node3 轮流出块。eosio节点将停止出块， 不能再给 eosio节点投票出块, eosio节点在此完成使命！
