##启动keosd、nodeos

##编译合约
eosio.contracts/build.sh

##创建钱包
cleos wallet create –to-console

##导入eosio密钥
cleos wallet import –private-key 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
##导入其他新创建的密钥
cleos wallet import –private-key 5KUUc1wsZuDiZSKjhVRH3iMz82A2bg58v2stzzyYzZWWeFhKp2H
cleos wallet import –private-key 5J3CA2Y57zkU6U4UPWgKJfgwA4eMs7gvGrLz8nxk5U7xtpFXb9a

发布合约

cleos set contract eosio /eosio.contracts/contracts/eosio.token/src eosio.token.wasm eosio.token.abi -p eosio

然后再创建account1、account2两个账户：
cleos create account eosio account1 EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
cleos create account eosio account2 EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

创建九个系统账户

这九个系统用户的名称及其作用如下说明：

eosio.bpay:矿工获取出块奖励的临时代管账户，增发EOS的1%的25%会先转到这个账户;

eosio.msig:多重签名管理的账户;

eosio.names:靓号账户拍卖管理的账户;

eosio.ram:内存买卖管理的账户;

eosio.ramfee:内存买卖收取手续费的账户，按照每笔交易千分之5的费率收取手续费;

eosio.saving:增发EOS临时存放账户，增发总量 5%，其中80%放在此账户，另外 20%再分成25%和75%，分别给eosio.bpay和eosio.vpay;

eosio.stake:管理EOS抵押的账户;

eosio.token:发行和管理token的账户;

eosio.vpay:矿工按照获得投票多少比例获取奖励的临时代管账户，增发EOS的1%的75%会先转到这个账户.

加载四大合约，发行代币

cleos set contract eosio.token /eosio.contracts/contracts/eosio.token
cleos set contract eosio.msig /eosio.contracts/contracts/eosio.msig
cleos push action eosio.token create ‘[“eosio”, “1000000000.0000 SYS”]’ -p eosio.token
cleos push action eosio.token issue ‘[“eosio”, “1000000000.0000 SYS”, “memo”]’ -p eosio

cleos set contract eosio /eosio.contracts/contracts/eosio.system
cleos push action eosio setpriv ‘[“eosio.msig”, 1]’ -p eosio@active

四大智能合约

eosio.bios
基本操作，设置帐户和全局操作限制、权限、生产者以及建立授权级别。
eosio.token
提供基本货币管理功能。包括创建货币、发行货币、转移货币。
eosio.msig
进行所需授权级别的多个签名。
eosio.system
让用户可以使用token，对生产者和工作人员进行配置和投票提案，可以经济且有效地建立和管理区块链。

加载系统智能合约并发币：
加载系统合约的时候有可能会有一个报错: ……too long. 可以在命令行最后面加上 -x 3000 的选项，3000是一个大概的数字，自行调整这个数据到正确运行为止；
智能合约的文件路径必须是全路径，尽量不要使用相对路径；
代币发行的大小是用的uint32_t类型，所以代币发行不能超过这个类型的数字，否则会报错；
系统合约加载不成功，检查一下九个系统用户是否正确创建，其它三个合约是否正确加载；

完成以后，在eosio用户里有10亿 SYS 代币，

创建普通用户

加载了eosio.system之后就不能使用create account命令了，只能用system newaccount创建账户

给创建的账户转账

cleos –wallet-url http://127.0.0.1:8900 –url http://192.168.154.157:8888 push action eosio.token transfer ‘[“eosio”, “zero”,”1000.0000 SYS”,”vote”]’ -p eosio

使用命令进行投票（自己给自己投票）

所有代币的15%进行投票后eosio会停止出块，主网会自动启动。在这里我们的代币数据数量总共是10亿，那么我们的主网启动需要1.5亿质押的代币进行投票后才能启动，质押的代币计算方式：staked = cpu + net：

cleos –wallet-url http://127.0.0.1:8900 –url http://192.168.154.157:8888 system voteproducer prods zero zero
cleos –wallet-url http://127.0.0.1:8900 –url http://192.168.154.157:8888 system voteproducer prods two two
cleos –wallet-url http://127.0.0.1:8900 –url http://192.168.154.157:8888 system voteproducer prods four four

结尾

过一段时间后就能看到节点轮流产块，创世节点只需同步块，如下所示

本文是在学习了q_776355102的博客后做的简单总结，有诸多详细命令请参考原文：

https://blog.csdn.net/weixin_39842528/article/details/81034018

更改节点出块数目

按上面的步骤可以让节点轮流出块了，但是每个节点出块个数是12，而不是像官网白皮书说的那样是6个，修改下相关代码就可以让节点出块个数变为6。

执行指令：vi libraries/chain/include/eosio/chain/config.hpp +99

//const static int producer_repetitions = 12;
const static int producer_repetitions = 6;
保存退出之后编译下源码，在按照上面的步骤再来一遍就可以看到如下界面：
