如何安装以管理员身份运行的Windows服务? [英] How do I install a windows service that runs as an administrator?

问题描述

我编写了一个安装程序，用于安装Windows服务(A)，该服务需要启动/停止其他服务(B).但是，当A尝试启动/停止B时，出现此异常:

I've written an installer that installs a windows service (A) that needs to start/stop another service (B). However, when A tries to start/stop B, I get this exception:

System.InvalidOperationException:无法在计算机."上打开MyService服务. ---> System.ComponentModel.Win32Exception:访问被拒绝

System.InvalidOperationException: Cannot open MyService service on computer '.'. ---> System.ComponentModel.Win32Exception: Access is denied

安装程序将服务安装为本地服务，并通过我授予的UAC弹出窗口请求管理员权限.我还向服务中添加了一个app.manifest文件，该文件设置为要求管理员权限:

The installer installs the service as a local service, and it requests admin rights via the UAC pop-up, which I grant. I've also added an app.manifest file to the service that is set to ask for admin rights:

但是我仍然遇到该错误.

Yet I'm still getting that error.

这是我启动服务的方式(停止是一样的，除了它当然叫停止):

This is how I start the service (stopping is the same, except it calls Stop, of course):

using (Mutex mutex = new Mutex(false, "MyServiceLock"))
{
    mutex.WaitOne();

    if (ServiceExists(serviceName) == true)
    {
        using (ServiceController serviceController = new ServiceController(serviceName, "."))
        {
            serviceController.Start(); // this line throws the exception
        }
    }

    mutex.ReleaseMutex();
}

为什么拒绝访问该服务?

Why might access to this service be denied?

推荐答案

服务无法请求UAC提升.在我看来，您描述的UAC提示实际上是安装程序而非服务所要求的.服务通常已经使用非常特权的帐户运行，默认情况下为LocalSystem.确保将服务配置为使用这样的特权帐户，而不是受限用户帐户.

A service cannot ask for a UAC elevation. It sounds to me that the UAC prompt you describe is actually requested by the installer, not the service. Services normally run with a very privileged account already, LocalSystem by default. Do make sure that you configure the service to use such a privileged account, not a restricted user account.
