「力场」——公链挖矿第一社区
因为吃过EOS版本的亏，所以先看下版本（主网最新版本mainnet-1.2.4，chain_id不是主网ID,因为只是单机版本）。本人系统是Ubunt18.04。
root@kang:/usr/local/eos# cleos get info
{
"server_version": "bbc8ff76",
"chain_id": "cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f",
"head_block_num": 17735,

}
首先修改下配置，找到
/home/kang/.local/share/eosio/nodeos/config下config.ini文件
contracts-console = false
把上面的`false`改成`true`，保存修改退出。这样我们就可以在终端直接看到智能合约的执行情况，然后重启nodeos（nodeos -e -p eosio --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin，此次有坑，1.1版本的时候要加钱包插件，当前版本不支持）。
加载基础合约（eosio账户创建并必须导入了公钥私钥）
kangzhiwang@kangzhiwang:/usr/local/eos$ cleos set contract eosio build/contracts/eosio.bios -p eosio@active

使用eosiocpp新建合约（eosiocpp环境变量记得配置）：
root@kang:/usr/local/eos/contracts# eosiocpp -n hello1
created hello1 from skeleton
进入hell01文件后：
#使用 -o 生成wast文件和wasm文件，
root@kang:/usr/local/eos/contracts/hello1# eosiocpp -o hello1.wast hello1.cpp
#使用 -g 生成abi文件
root@kang:/usr/local/eos/contracts/hello1# eosiocpp -g hello1.abi hello1.cpp
可以看到生成了文件
root@kang:/usr/local/eos/contracts/hello1# ls
hello1.cpp hello1.hpp hello1.wasm hello1.wast
发布合约
cleos set contract eosio /usr/local/eos/contracts/hello1 -p eosio@active
调用合约：kang是调用者用户
root@kang:/usr/local/eos# cleos push action eosio hi '["kang"]' -p kang

>> Hello, kang
×必须完成钱包的创建
×必须完成eosio账户的创建
×必须完成调用者的创建
×config.ini中插件配置（去掉wallet_api_plugin）
plugin = eosio::chain_plugin
plugin = eosio::chain_api_plugin
plugin = eosio::net_plugin
plugin = eosio::net_api_plugin
plugin = eosio::history_plugin
#plugin = eosio::wallet_api_plugin
plugin = eosio::history_api_plugin
plugin = eosio::http_plugin
plugin = eosio::http_client_plugin
