搭建你自己的比特股测试网(上篇) - How to build your own bitshares testnet (part I)

1.服务器准备

这次测试网准备了3台服务器，分别命名为node-1,node-2和node-3，条件允许的话可以准备更多台。

服务器使用ubuntu 16.4 LTS版本，是编译最方便的linux版本，具体的编译方法参见《在ubuntu上编译比特股核心代码》

新建testnet目录，将witness_node文件拷贝到testnet目录

mkdir /testnet

cp program/witness_node/witness_node /testnet/

2.生成秘钥对和地址

programs/genesis_util/get_dev_key BTS w1 w2 w3 admin

运行以上命令会生成四对秘钥对和地址，分别对应w1，w2，w3和admin的私钥、公钥和地址如下

[{"private_key":"5JjzogP6V1TciYQHthBLPnmj5cyrYLfwfoDeY6rpG4mcNUd7hDq","public_key":"BTS6WqFcNmb8DA8SG2HJDL23TzSKk67HrCf6qTeqXhbCcohi11epm","address":"BTSMZq4SyNoFGraCNuV5ZjbJHMvcYBLSV3rM"},

{"private_key":"5JpX8v4y7HQ9EXLRGPXcPCVCqw5BLzP2drAbwJ94P3QXFxxwzkw","public_key":"BTS8ftmc4mCUjnR43SPtQFg8xuJgUr82MKuBjvegrmdDasohZcpZw","address":"BTSP1gitSEvGzCLCa9rsCCfQiRSzNQquDUxX"},

{"private_key":"5HtEtfFYt1eGpE6uVWMyzMXzh8BBYfPyfH2A8Q8FQvXgdFXsc7N","public_key":"BTS7hKorE5txmsT6qee9NNqcYqNvBU1Umxk1cV93Q1XPEbYCacpfM","address":"BTSCSSgBtAUAGkhFbo6rbUMqtNTJteWaxHdG"},

{"private_key":"5KNP4D9K3FL1gBtRtanhfgLZTpz1wcJVsLEQXonRMeAwzMDL2se","public_key":"BTS51ABY2MWbn3W5NNW3JNJRDraEi4JbzEAmBa3jiTQJ7f99Z7xJ6","address":"BTS21sMK9h93c1i29wLKi29xqKxqjvLSEarw"}]

3.初始化创始区块配置文件

cd /tesnet

./witness_node --create-genesis-json testnet.json

编辑testnet.json文件

vim testnet.json

找到initial_accounts一节,修改初始账号的名称和公钥,将初始的11个witness账号都改成w1对应的公钥，如下：

{

"name": "w1-0",

"owner_key": "BTS6WqFcNmb8DA8SG2HJDL23TzSKk67HrCf6qTeqXhbCcohi11epm",

"active_key": "BTS6WqFcNmb8DA8SG2HJDL23TzSKk67HrCf6qTeqXhbCcohi11epm",

"is_lifetime_member": true

}

修改初始账号中nathan用户的名称和公钥，如下

{

"name": "admin",

"owner_key": "BTS51ABY2MWbn3W5NNW3JNJRDraEi4JbzEAmBa3jiTQJ7f99Z7xJ6",

"active_key": "BTS51ABY2MWbn3W5NNW3JNJRDraEi4JbzEAmBa3jiTQJ7f99Z7xJ6",

"is_lifetime_member": true

}

找到initial_balances一节，修改初始账号余额，这里我们把所有的核心资产都交给admin用户，如下：

{

"owner": "BTS21sMK9h93c1i29wLKi29xqKxqjvLSEarw", //填写admin的address

"asset_symbol": "BTS",

"amount": "1000000000000000"

}

找到initial_witness_candidates一节，修改初始的witness见证人，如下

{

"owner_name": "w1-0",

"block_signing_key": "BTS6WqFcNmb8DA8SG2HJDL23TzSKk67HrCf6qTeqXhbCcohi11epm" //公钥

}

找到initial_committee_candidates，修改初始的委员会成员，如下

{

"owner_name": "w1-0"

}

保存退出

3.初始化创世区块和配置文件

运行以下命令，初始化创世区块

./witness_node --data-dir data --genesis-json test-net.json

这一步会新建data目录，并且运行到最后会打印出chain-id，这时候ctrl-c停止程序运行，并且记录chain-id备用。

打开data目录下的config.ini文件

vim data/config.ini

修改如下：

p2p-endpoint = 0.0.0.0:10101 //seed节点的ip和端口，端口可以自定义

rpc-endpoint = 0.0.0.0:11011 //rpc的ip和端口

genesis-json = testnet.json

enable-stale-production = true

witness-id = "1.6.1"

...

witness-id = "1.6.11"

private-keys = ["BTS6WqFcNmb8DA8SG2HJDL23TzSKk67HrCf6qTeqXhbCcohi11epm","5JjzogP6V1TciYQHthBLPnmj5cyrYLfwfoDeY6rpG4mcNUd7hDq"] //公钥、私钥对

debug-private-keys = ["BTS6WqFcNmb8DA8SG2HJDL23TzSKk67HrCf6qTeqXhbCcohi11epm","5JjzogP6V1TciYQHthBLPnmj5cyrYLfwfoDeY6rpG4mcNUd7hDq"] //公钥、私钥对

保存退出

4.运行网络中的第一个节点
