一 运行eos客户端,启动私有网络
./nodeos -e -p eosio --plugin eosio::wallet_api_plugin --plugin eosio::chain_api_plugin --plugin eosio::account_history_api_plugin
eosio generated block bcc817bc... #637 @ 2018-05-10T09:22:13.000 with 0 trxs, lib: 636
eosio generated block 527d07ae... #638 @ 2018-05-10T09:22:13.500 with 0 trxs, lib: 637
二 创建合约代码
mkdir hello
vim hello.cpp
输入合约内容,并保存
#include <eosiolib/eosio.hpp>
#include <eosiolib/print.hpp>
using namespace eosio;
class hello : public eosio::contract {
public:
using contract::contract;
/// @abi action
void hi( account_name user ) {
print( "Hello, ", name{user} );
}
};
EOSIO_ABI( hello, (hi) )
三 编译生成wast文件
eosiocpp -o hello.wast hello.cpp

注意：
(1)如钱包锁定，请使用命令解锁“ cleos wallet unlock --password 钱包私钥”，不然提示
Error 3030002: signatures do not satisfy declared authorizations
Ensure that you have the related private keys inside your wallet and you wallet is unlocked.
(2)用户用上一章创建的bytemaster,如未创建，参考《使用EOS3.0发行代币》创建用户。
六 执行合约
cleos push action bytemaster hi '["bytemaster"]' -p bytemaster
executed transaction: 5d139b060e83bdda2aec63c531587cf1877776034af7396d2822f99a70afca8a 232 bytes 102400 cycles
# bytemaster <= bytemaster::hi {"user":"bytemaster"}
>> Hello, bytemaster
七 总结
智能合约开发步骤
（1）运行eos客户端,启动私有网络
（2）编写合约cpp文件
（3）合约cpp编译为wast格式
（4）创建合约的abi
（5）解锁钱包
（6）部署合约
（7）执行合约
