安装依赖库

apt install libargtable2-dev
apt install libhiredis-dev

升级jsonrcpcpp，修改CMakeLists.txt

1：在cmake集成JsonRpcCpp

把ProjectJsonRpcCpp.cmake 和 FindMHD.cmake 两个文件拷贝到cmake 目录

2: 添加 HttpServer 源代码

SafeHttpServer.cpp
SafeHttpServer.h

3：集成HttpJsonRpc

添加遍历定义：
int jsonRPCURL = -1;
bool adminViaHttp = false;
std::string rpcCorsDomain = "";
std::string httpsKey = "";
std::string httpsCert = "";

添加参数处理：

if (vm.count("json-rpc-port"))
    {
        jsonRPCURL = vm["json-rpc-port"].as<short>();
    }
    if (vm.count("admin-via-http"))
    {
        string m = vm["admin-via-http"].as<string>();
        if (isTrue(m))
            adminViaHttp = true;
        else if (isFalse(m))
            adminViaHttp = false;
        else
        {
            cerr << "Bad " << "--admin-via-http" << " option: " << m << "\n";
            return -1;
        }
    }
    if (vm.count("rpccorsdomain"))
    {
        rpcCorsDomain = vm["rpccorsdomain"].as<string>();

        string::size_type pos = rpcCorsDomain.find_first_not_of('"');
        if (pos != string::npos)
        {
            rpcCorsDomain = rpcCorsDomain.substr(pos);
        }

        pos = rpcCorsDomain.find_last_not_of('"');
        if (pos != string::npos)
        {
            rpcCorsDomain = rpcCorsDomain.substr(0, pos+1);
        }

        cdebug << "rpcCorsDomain=" << rpcCorsDomain;
    }
    if (vm.count("https_key"))
    {
        httpsKey = vm["rpccorsdomain"].as<string>();
        cdebug << "httpsKey=" << httpsKey;
    }
    if (vm.count("https_cert"))
    {
        httpsCert = vm["rpccorsdomain"].as<string>();
        cdebug << "httpsCert=" << httpsCert;
    }

在程序启动时启动httpJsonRpc 服务器

if (jsonRPCURL > -1)
    {
        using FullServer = ModularServer<
            rpc::EthFace,
            rpc::NetFace, rpc::Web3Face, rpc::PersonalFace,
            rpc::AdminEthFace, rpc::AdminNetFace,
            rpc::DebugFace, rpc::TestFace
        >;

        rpc::AdminEth* adminEth = nullptr;
        rpc::PersonalFace* personal = nullptr;
        rpc::AdminNet* adminNet = nullptr;
        if (adminViaHttp)
        {
            personal = new rpc::Personal(keyManager, *accountHolder, *web3.ethereum());
            adminEth = new rpc::AdminEth(*web3.ethereum(), *gasPricer.get(), keyManager, *sessionManager.get());
            adminNet = new rpc::AdminNet(web3, *sessionManager.get());
        }

        auto ethFace = new rpc::Eth(*web3.ethereum(), *accountHolder.get());
        rpc::TestFace* testEth = nullptr;
        if (testingMode)
            testEth = new rpc::Test(*web3.ethereum());

        jsonrpcHttpServer.reset(new FullServer(
            ethFace,
            new rpc::Net(web3), new rpc::Web3(web3.clientVersion()), personal,
            adminEth, adminNet,
            new rpc::Debug(*web3.ethereum()),
            testEth
        ));

        unsigned SensibleHttpThreads = 1;
        auto httpConnector = new SafeHttpServer(jsonRPCURL, httpsKey, httpsCert, SensibleHttpThreads);
        httpConnector->setAllowedOrigin(rpcCorsDomain);
        jsonrpcHttpServer->addConnector(httpConnector);
        jsonrpcHttpServer->StartListening();

        cout << "JSONRPC Admin Session Key: " << jsonAdmin << "\n";
    }

结束时关闭服务器

if (jsonrpcHttpServer.get())
        jsonrpcHttpServer->StopListening();

修改libweb3jsonrpc/CMakeLists.txt 文件

target_link_libraries(web3jsonrpc ethashseal webthree libjson-rpc-cpp::server) 
改为
target_link_libraries(web3jsonrpc ethashseal webthree libjson-rpc-cpp::server JsonRpcCpp::Server) 

set(sources AccountHolder.cpp
