将qt程序注册成服务

1、qt服务模块管理下载

qt-solutions

2、QtService项目

2.1、将qtservice拷贝到项目代码路径

2.2、实现服务管理

PS：响应服务的启停
CustomService.h

#include <QCoreApplication>
#include "qtservice.h"


class CustomService : public QtService<QCoreApplication>
{
public:
    CustomService(int argc, char **argv);

protected:
    void start();

    void pause();

    void resume();

    void stop();


};

CustomService.cpp

#include "CustomService.h"
#include "ServiceHandle.h"


CustomService::CustomService(int argc, char **argv)
    : QtService<QCoreApplication>(argc, argv, "Custom Qt Server")
{
    setServiceDescription("Custom Qt Server");
    setServiceFlags(QtServiceBase::CanBeSuspended);
}

void CustomService::start()
{
    QCoreApplication *app = application();

    SERVER_CTRL_INST.start();
}

void CustomService::pause()
{
    SERVER_CTRL_INST.pause();
}

void CustomService::resume()
{
    SERVER_CTRL_INST.resume();
}

void CustomService::stop()
{
    SERVER_CTRL_INST.stop();
}

2.3、服务内部程序实现

ServiceHandle.h

#pragma once
#include "ThreadObject.h"



#define SERVER_CTRL_INST ServiceHandle::Instance()
class ServiceHandle
{
    const std::string kProcessName = "QtService.exe";
public:
    static ServiceHandle& Instance()
    {
        static ServiceHandle g_inst;
        return g_inst;
    }

protected:
    ServiceHandle();
    ~ServiceHandle();

public:
    void InstallService(const std::string& strServiceName = "");
    void StartService(const std::string& strServiceName);
    void StopService(const std::string& strServiceName);
    void UninstallService(const std::string& strServiceName);
    void start();
    void pause();
    void resume();
    void stop();


private:
    void do_work();


private:
    Utils::ThreadObject m_objWork;



};

ServiceHandle.cpp

#include "ServiceHandle.h"
#include <fstream>
#include <QProcess>
#include <iostream>
#include <direct.h>
#include "Command.h"


static int64_t g_nCnt =0;
ServiceHandle::ServiceHandle()
{
}


ServiceHandle::~ServiceHandle()
{

}

void ServiceHandle::InstallService(const std::string& strServiceName/* = ""*/)
{
    char szPath[260] = { 0 };
    getcwd(szPath, 260);
    std::string strPath(szPath);
    strPath = strPath + "/" + kProcessName;
    std::cout << "Exe path: " << szPath << "\n";
    std::string strName = strServiceName.empty()? "CustomService": strServiceName;
    std::string strCmd = "sc create " + strName + " binpath=" + strPath;
    std::string strResponse = Utils::CommandHelper::ExecCommand(strCmd);
    std::cout << strResponse;

    // start service
    StartService(strName);
}

void ServiceHandle::StartService(const std::string& strServiceName)
{
    std::string strCmd = "net start " + strServiceName;
    std::string strResponse = Utils::CommandHelper::ExecCommand(strCmd);
    std::cout << strResponse;
}

void ServiceHandle::StopService(const std::string& strServiceName)
{
    std::string strCmd = "net stop " + strServiceName;
    std::string strResponse = Utils::CommandHelper::ExecCommand(strCmd);
    std::cout << strResponse;
}

void ServiceHandle::UninstallService(const std::string& strServiceName)
{
    StopService(strServiceName);
    std::string strCmd = "sc delete " + strServiceName;
    std::string strResponse = Utils::CommandHelper::ExecCommand(strCmd);
    std::cout << strResponse;
}

void ServiceHandle::start()
{
    g_nCnt = 0;
    m_objWork.Start(std::bind(&ServiceHandle::do_work, &SERVER_CTRL_INST), 2000);
}

void ServiceHandle::pause()
{
    stop();
}

void ServiceHandle::resume()
{
    start();
}

void ServiceHandle::stop()
{
    m_objWork.Stop();
}

void ServiceHandle::do_work()
{
    std::fstream fout("C:\\ProgramData\\CustomService.log", std::ios::out | std::ios::app);
    if(fout.is_open()) {
        fout << "Server do work: " << ++g_nCnt << "\n";
        fout.close();
    }
}

2.4、服务本身支持指令操作

PS：安装、卸载、启停以及常规启动（非服务）
main.cpp

#include <QApplication>
#include <iostream>
#include <string>
#include <map>
#include "CustomService.h"
#include "ServiceHandle.h"


enum ServiceCmdType
{
    kServiceCmdTypeUnknown = -1,
    kServiceCmdTypeHelp,
    kServiceCmdTypeCommon,
    kServiceCmdTypeInstall,
    kServiceCmdTypeUninstall,
    kServiceCmdTypeStart,
    kServiceCmdTypeStop

};

std::map<std::string, ServiceCmdType> mapCmd
{
    { "help", kServiceCmdTypeHelp },
    { "common", kServiceCmdTypeCommon },
    { "install", kServiceCmdTypeInstall },
    { "uninstall", kServiceCmdTypeUninstall },
    { "start", kServiceCmdTypeStart },
    { "stop", kServiceCmdTypeStop }

};

void Usage()
{
    std::cout << "Usage: QtService [command] [option1] [option2]\n";
    std::cout << "command and options:\n";
    std::cout << "\tinstall [service name]:     install service, <service name> is optional, default is \"Custom Qt Server\" \n";
    std::cout << "\tstop [service name]:        stop service\n";
    std::cout << "\tstart [service name]:       start service\n";
    std::cout << "\tuninstall [service name]:   uninstall service\n";
    std::cout << "\tcommon:                     start process in common mode\n";
    std::cout << "\thelp:                       show usage\n";
}

bool CheckValidCmd(const std::string& strCmd, ServiceCmdType& nCmd)
{
    bool bValid = false;
    auto itFind = mapCmd.find(strCmd);
    if(itFind != mapCmd.end()) {
        bValid = true;
        nCmd = itFind->second;
    }

    return bValid;
}

// install/uninstall/start/stop service via inner action
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    if(argc > 1) {
        int nIndex = 0;
        std::string strCmd = argv[++nIndex];
        ServiceCmdType nCmdType = kServiceCmdTypeUnknown;
        if(!CheckValidCmd(strCmd, nCmdType) || kServiceCmdTypeHelp == nCmdType) {
            Usage();
            return 0;
        }
        if(kServiceCmdTypeCommon == nCmdType) {
            SERVER_CTRL_INST.start();
            auto nCode = a.exec();
            SERVER_CTRL_INST.stop();
            return nCode;
        }
        if(argc < 3) {
            Usage();
            return 0;
        }

        std::string strServiceName = argv[++nIndex];
        switch(nCmdType) {
        case kServiceCmdTypeInstall: {
            SERVER_CTRL_INST.InstallService(strServiceName);
            break;
        }
        case kServiceCmdTypeUninstall: {
            SERVER_CTRL_INST.UninstallService(strServiceName);
            break;
        }
        case kServiceCmdTypeStart: {
            SERVER_CTRL_INST.StartService(strServiceName);
            break;
        }
        case kServiceCmdTypeStop: {
            SERVER_CTRL_INST.StopService(strServiceName);
            break;
        }
        default:
            break;
        }
        return 0;
    }
    // start exe with service(default)
    CustomService service(argc, argv);
    return service.exec();
}

PS：
1、qt.pro里增加CONFIG+=console，这样控制台有数据输出
2、unix下注册服务，修改对应注册服务命令即可
3、服务注册原理，外层一个壳子，响应服务操作，然后再执行对应逻辑
