Menginstal Layanan

  • Artikel

Program konfigurasi layanan menggunakan fungsi CreateService untuk menginstal layanan di database SCM.

Fungsi SvcInstall dalam contoh berikut menunjukkan cara menginstal layanan dari program layanan itu sendiri. Untuk contoh lengkapnya, lihat Svc.cpp.

//
// Purpose: 
//   Installs a service in the SCM database
//
// Parameters:
//   None
// 
// Return value:
//   None
//
VOID SvcInstall()
{
    SC_HANDLE schSCManager;
    SC_HANDLE schService;
    TCHAR szPath[MAX_PATH];

    if( !GetModuleFileName( NULL, szPath, MAX_PATH ) )
    {
        printf("Cannot install service (%d)\n", GetLastError());
        return;
    }

    // Get a handle to the SCM database. 
 
    schSCManager = OpenSCManager( 
        NULL,                    // local computer
        NULL,                    // ServicesActive database 
        SC_MANAGER_ALL_ACCESS);  // full access rights 
 
    if (NULL == schSCManager) 
    {
        printf("OpenSCManager failed (%d)\n", GetLastError());
        return;
    }

    // Create the service

    schService = CreateService( 
        schSCManager,              // SCM database 
        SVCNAME,                   // name of service 
        SVCNAME,                   // service name to display 
        SERVICE_ALL_ACCESS,        // desired access 
        SERVICE_WIN32_OWN_PROCESS, // service type 
        SERVICE_DEMAND_START,      // start type 
        SERVICE_ERROR_NORMAL,      // error control type 
        szPath,                    // path to service's binary 
        NULL,                      // no load ordering group 
        NULL,                      // no tag identifier 
        NULL,                      // no dependencies 
        NULL,                      // LocalSystem account 
        NULL);                     // no password 
 
    if (schService == NULL) 
    {
        printf("CreateService failed (%d)\n", GetLastError()); 
        CloseServiceHandle(schSCManager);
        return;
    }
    else printf("Service installed successfully\n"); 

    CloseServiceHandle(schService); 
    CloseServiceHandle(schSCManager);
}
