测试时,GOC在Github上的代码目前以私有方式提供,因此首先需向测试网维护人员提供Github账户名,以便授予权限,联系方式见文末。
具体GOC代码包括:
GOC代码:GOC testnet
fc submodule代码(调整了Primary key prefix):Changed fc submodule
另,我们会在微信GOC测试网公测群发布关于源码分支的信息,重大调整会通过分支的方式预先发布,经过充分测试后,才合并至master主分支。
获得权限后,在命令行终端窗口执行以下命令获取代码并编译:
cd ~ # 退出当前目录,进入主目录
git clone git@github.com:BlockchainLabFudan/GOCtestnet.git
cd GOCtestnet
git submodule update --init --recursive
sudo ./eosio_build.sh -s 'GOC'
sudo ./eosio_install.sh
获取BP账户需先准备好相关信息(如服务器IP)并提交至Github上,然后联系测试网维护人员创建BP账户,具体步骤如下:
1、Fork本repository
2、Clone Fork的repository(不是本repo)到本地
git clone git@github.com:xxxxxxxx/GOC-testnet.git
# xxxxxxxx替换为你自己的GitHub帐号
3、以gravitypool.ini为例,新建bp-name.ini到producer-info文件夹中,bp-name为你的BP名称
4、将BP名称和p2p-peer-address添加到config.ini文件末尾(以已有信息为例)
5、创建一个pull request将你的BP信息提交至GOC-testnet上
6、联系测试网维护人员创建BP账户
账户创建完成后,将BP账户注册为出块BP:
~/GOCtestnet/build/programs/keosd/keosd # 启动钱包服务
cd ~/GOCtestnet/build/programs/cleos # 进入cleos目录
./cleos wallet create --to-console # 默认创建名为default的钱包,记录显示的钱包密码
./cleos wallet import # 导入BP账户。运行后会提示输入私钥,输入BP账户的私钥
./cleos wallet create_key # 创建一对公私钥作为producer key
./cleos -u http://47.52.114.54:8888 system regproducer 'yourbpname' 'your_producer_pub_key'
# yourbpname为你的BP账户名,your_producer_pub_key为上一条命令创建的公钥
注:若钱包15分钟未使用,会提示钱包被锁,需要用以下命令解锁钱包:
./cleos wallet unlock # 根据提示输入钱包密码即可
1、genesis.json
在~/GOCtestnet/build/programs/nodeos文件夹下创建 genesis.json 文件,填入以下内容:
{
"initial_timestamp": "2018-09-09T09:09:09.999",
"initial_key": "GOC7oiy488wfzwbR6L9QwNDQb4CHGVR5ix9udJjVyykgbLaQLgBc5",
"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
}
}
genesis.json文件定义了初始链状态,所有节点必须从相同的初始状态开始
2、config.ini
将GOC-testnet里的config.ini复制到~/GOCtestnet/build/programs/nodeos文件夹下,注意要将自己的p2p-peer-address移除
准备好一切之后,便可启动出块节点,连接测试网:
cd ~/GOCtestnet/build/programs/nodeos
./nodeos --genesis-json ./genesis.json --config-dir ~/GOCtestnet/build/programs/nodeos --http-server-address 0.0.0.0:8888 --p2p-listen-endpoint 0.0.0.0:9876 --http-validate-host=false --producer-name 'yourbpname' --signature-provider='your_producer_pub_key'=KEY:'your_producer_private_key' --plugin eosio::http_plugin --plugin eosio::chain_api_plugin --plugin eosio::producer_plugin --plugin eosio::history_api_plugin
# yourbpname填入BP账户名; your_producer_pub_key、your_producer_private_key分别填入创建的producer key的公钥和私钥。
连接测试网,会先同步测试网中已生产的块,等待一段时间同步完成后,每0.5s会收到出块节点产出的块,终端显示如下示例信息:
2018-09-29T10:47:23.478 thread-0 producer_plugin.cpp:332 on_incoming_block ] Received block 9838cc2c992c2725... #406196 @ 2018-09-29T10:47:23.500 signed by producer111h [trxs: 0, lib: 406028, conf: 0, latency: -21 ms]
2018-09-29T10:47:24.072 thread-0 producer_plugin.cpp:332 on_incoming_block ] Received block 3624e2ab8697a1e1... #406197 @ 2018-09-29T10:47:24.000 signed by producer111i [trxs: 0, lib: 406040, conf: 120, latency: 72 ms]
再打开另一个命令行终端窗口,输入以下命令:
cd ~/GOCtestnet/build/programs/cleos
./cleos system voteproducer prods 'yourbpname' 'yourbpname'
# yourbpname填入BP账户名
./cleos get schedule
# 查看当前测试网出块节点
当nodeos同步到最新块,且得票数足够多BP账户出现在schedule中时,便可观察自己的节点是否正常出块
