本文将介绍在本地部署EOS的多节点私链的方案。

1.创建三个数据文件夹

用来存储相关的数据，每个文件夹下包括创世文件genesis.json和配置文件config.ini。

mkdir -p eostest1 eostest2 eostest3

三个节点的genesis.json都相同，内容为：

vim eostest1/genesis.json

{
  "initial_timestamp": "2018-03-01T12:00:00.000",
  "initial_key": "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV",
  "initial_configuration": {
    "base_per_transaction_net_usage": 100,
    "base_per_transaction_cpu_usage": 500,
    "base_per_action_cpu_usage": 1000,
    "base_setcode_cpu_usage": 2097152,
    "per_signature_cpu_usage": 100000,
    "per_lock_net_usage": 32,
    "context_free_discount_cpu_usage_num": 20,
    "context_free_discount_cpu_usage_den": 100,
    "max_transaction_cpu_usage": 10485760,
    "max_transaction_net_usage": 104857,
    "max_block_cpu_usage": 104857600,
    "target_block_cpu_usage_pct": 1000,
    "max_block_net_usage": 1048576,
    "target_block_net_usage_pct": 1000,
    "max_transaction_lifetime": 3600,
    "max_transaction_exec_time": 0,
    "max_authority_depth": 6,
    "max_inline_depth": 4,
    "max_inline_action_size": 4096,
    "max_generated_transaction_count": 16
  },
  
  "initial_chain_id": "0000000000000000000000000000000000000000000000000000000000000000"
}

2.启动节点(1)

节点1的config.ini文件内容为：

blocks-dir = "blocks"
bnet-endpoint = 0.0.0.0:4321
http-server-address = 0.0.0.0:8888
p2p-listen-endpoint = 0.0.0.0:9876
p2p-server-address = localhost:9876
allowed-connection = any
signature-provider = EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
producer-name = eosio
plugin = eosio::producer_plugin
plugin = eosio::chain_api_plugin
plugin = eosio::history_api_plugin
plugin = eosio::http_plugin
enable-stale-production = true

配置选项如下：

http-server-address = 0.0.0.0:8888，这里设置四个0代表本地可以通过localhost或者127.0.0.1调用http接口，同时外部可以通过本机固定ip访问。
p2p-listen-endpoint = 0.0.0.0:9876，p2p网络本机监听端口，监听外部接入的p2p节点，这里的四个0的ip配置意义同上。
bnet-endpoint = 0.0.0.0:4321，bnet是使用一个非常简单的算法来同步两条区块链。主要工作是两条链上的确权，共识，广播，同步区块，保持默认配置即可。
p2p-peer-address = ip:port，对端p2p节点地址，可以设置多个。
producer-name = eosio，配置出块的账户采用eosio
enable-stale-production = true，意思是可以不经过确权直接出块，单节点时要配置为true，多节点出块由于需要各方确权共识，要配置为false。
signature-provider = EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3 ，密钥对，公钥加私钥，对应eosio账户，这对秘钥是写死的，不可改变。

然后启动节点(1)并让它出块：

cd eostest1
nodeos --data-dir ./ --config-dir ./

3.创建账户用来启动节点(2)和(3)

创建默认钱包default

👍 cleos wallet create  --to-console
Error 3120001: Wallet already exists
Try to use different wallet name.

如果创建过，进行解锁：

cleos wallet unlock
password: Unlocked: default

将创建节点1的私钥密钥导入钱包

cleos wallet import --private-key 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
imported private key for: EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

然后发布eosio.bios合约：

cleos set contract eosio build/contracts/eosio.bios/
Reading WASM from /wwwroot/block_chain/eos/build/contracts/eosio.bios/eosio.bios.wasm...
Publishing contract...
executed transaction: 9eca4b74c8608974da726a1d96f972537e9bf7359d41442b6a083c2410a65847  4352 bytes  12020 us
#         eosio <= eosio::setcode               {"account":"eosio","vmtype":0,"vmversion":0,"code":"0061736d0100000001621260037f7e7f0060057f7e7e7e7e...
#         eosio <= eosio::setabi                {"account":"eosio","abi":"0e656f73696f3a3a6162692f312e30050c6163636f756e745f6e616d65046e616d650f7065...
warning: transaction executed locally, but may not be confirmed by the network yet         ]

然后再创建inita、initb两个账户：

$ cleos create account eosio inita EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
executed transaction: c9d76cd299a701c516c46406cd9054b07b8dacfb5dd1cd682c5c8f248577f2ad  200 bytes  4800 us
#         eosio <= eosio::newaccount            {"creator":"eosio","name":"inita","owner":{"threshold":1,"keys":[{"key":"EOS6MRyAjQq8ud7hVNYcfnVPJqc...
warning: transaction executed locally, but may not be confirmed by the network yet         ]

$ cleos create account eosio initb EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
executed transaction: e5492b4d415345bff1bc66adf636b6854231aa78977c447c86b6953101d6f42d  200 bytes  194 us
#         eosio <= eosio::newaccount            {"creator":"eosio","name":"initb","owner":{"threshold":1,"keys":[{"key":"EOS6MRyAjQq8ud7hVNYcfnVPJqc...
warning: transaction executed locally, but may not be confirmed by the network yet         ]

4.启动节点(2)

节点2的config.ini文件：

blocks-dir = "blocks"
bnet-endpoint = 0.0.0.0:4321
http-server-address = 0.0.0.0:8889
p2p-listen-endpoint = 0.0.0.0:9877
p2p-server-address = localhost:9877
allowed-connection = any
p2p-peer-address = localhost:9876
signature-provider = EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
producer-name = inita
plugin = eosio::producer_plugin
plugin = eosio::chain_api_plugin
plugin = eosio::history_api_plugin
plugin = eosio::http_plugin

注意修改以下几项代表了该节点的信息：

p2p-peer-address = localhost:9876 节点(1)的p2p服务地址，通过该配置项使节点(2)链接上节点(1)
producer-name = inita，节点2的出块账户设置为inita
enable-stale-production = false 不允许节点2在不经确认直接出块的功能
http-server-address = 0.0.0.0:8889 该节点的server 端口
p2p-listen-endpoint = 0.0.0.0:9877 p2p网络本机监听端口，监听外部接入的p2p节点
p2p-server-address = 0.0.0.0:9877 p2p网络服务节点端口

启动节点2：

cd eostest2
nodeos --data-dir ./ --config-dir ./

可以看到节点2连上了节点1并进行了同步，此时节点2还不能出块。

info  2019-01-10T07:20:22.004 thread-0  producer_plugin.cpp:341       on_incoming_block    ] Received block c8ae236b27e648d3... #8533 @ 2019-01-10T07:20:22.000 signed by inita [trxs: 0, lib: 8464, conf: 0, latency: 4 ms]

配置节点(2)可以出块，在节点(1)上执行命令：

$ cleos push action eosio setprods '{"schedule":[{"producer_name":"inita","block_signing_key":"EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV"}]}' -p eosio

info  2019-01-10T07:20:52.005 thread-0  producer_plugin.cpp:1494      produce_block        ] Produced block 000021919d63255e... #8593 @ 2019-01-10T07:20:52.000 signed by inita [trxs: 0, lib: 8572, confirmed: 0]

而节点1由出块者变成了同步者：

info  2019-01-10T07:26:55.004 thread-0  producer_plugin.cpp:341       on_incoming_block    ] Received block c6c6536853f2ee5c... #9319 @ 2019-01-10T07:26:55.000 signed by initb [trxs: 0, lib: 9304, conf: 0, latency: 4 ms]

info  2019-01-10T07:26:56.005 thread-0  producer_plugin.cpp:341       on_incoming_block    ] Received block 2c795666435af362... #9321 @ 2019-01-10T07:26:56.000 signed by initb [trxs: 0, lib: 9304, conf: 0, latency: 5 ms]

5.启动节点(3)

节点3的config.ini文件：

blocks-dir = "blocks"
bnet-endpoint = 0.0.0.0:4321
http-server-address = 0.0.0.0:8890
p2p-listen-endpoint = 0.0.0.0:9878
p2p-server-address = localhost:9878
allowed-connection = any
p2p-peer-address = localhost:9877
signature-provider = EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
producer-name = initb
plugin = eosio::producer_plugin
plugin = eosio::chain_api_plugin
plugin = eosio::history_api_plugin
plugin = eosio::http_plugin

节点(3)的出块账户设置为initb，另外要注意的是节点(3)的p2p连接节点不能设置为节点(1)，因为此时节点(1)已经不是生产者了。节点(3)的连接节点应该设置为节点(2)的地址p2p-peer-address = localhost:9877。

启动节点3：

$ cd eostest3
$ nodeos --data-dir ./ --config-dir ./

info  2019-01-10T07:30:49.003 thread-0  producer_plugin.cpp:341       on_incoming_block    ] Received block e745e7582cef727e... #9787 @ 2019-01-10T07:30:49.000 signed by inita [trxs: 0, lib: 9772, conf: 0, latency: 3 ms]
info  2019-01-10T07:30:49.502 thread-0  producer_plugin.cpp:341       on_incoming_block    ] Received block 9fae21e7f5376742... #9788 @ 2019-01-10T07:30:49.500 signed by inita [trxs: 0, lib: 9772, conf: 0, latency: 2 ms]
info  2019-01-10T07:30:50.007 thread-0  producer_plugin.cpp:341       on_incoming_block    ] Received block 0e4320dbc2ac5f73... #9789 @ 2019-01-10T07:30:50.000 signed by inita [trxs: 0, lib: 9772, conf: 0, latency: 7 ms]

为了让节点3成为出块者，需要执行命令：

$ cleos push action eosio setprods '{"schedule":[{"producer_name":"inita","block_signing_key":"EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV"},{"producer_name":"initb","block_signing_key":"EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV"}]}' -p eosio

info  2019-01-10T07:34:42.501 thread-0  producer_plugin.cpp:1494      produce_block        ] Produced block 0000280e93eaf396... #10254 @ 2019-01-10T07:34:42.500 signed by initb [trxs: 0, lib: 10240, confirmed: 0]
info  2019-01-10T07:34:43.003 thread-0  producer_plugin.cpp:1494      produce_block        ] Produced block 0000280f2c03ef11... #10255 @ 2019-01-10T07:34:43.000 signed by initb [trxs: 0, lib: 10240, confirmed: 0]
info  2019-01-10T07:34:43.504 thread-0  producer_plugin.cpp:1494      produce_block        ] Produced block 0000281013ed3c65... #10256 @ 2019-01-10T07:34:43.500 signed by initb [trxs: 0, lib: 10240, confirmed: 0]

可以看到此时节点1和节点2交替出块了，每个节点在轮到它出块时连续生产了12个块。
