使用Inno Setup升级Windows服务

Question

我使用Inno Setup创建了一个基本的Windows服务安装。 安装和卸载都正常工作。

但是，我在升级过程中遇到问题。

为了升级服务可执行文件，必须停止服务，并且只有在服务完全停止后，才能将更新的可执行文件放在目标文件夹中。

如何在启动文件部署步骤之前执行service-stop命令并等待服务完全停止？

Answer 1

以下代码来自以下页面：
http://www.vincenzo.net/isxkb/index.php?title=Service_-_Functions_to_Start%2C_Stop%2C_Install%2C_Remove_a_Service

但是，我必须应用一个小修补程序才能使其正常工作。

请注意，我最初在2010年发布了此答案。上面页面中的代码已在2011年更新，因此可能值得一游。

我在安装程序中使用此代码作为#include 。 它是在Inno Setup ANSI中编译的。
它可以通过更换为Inno Setup的Unicode版本工作A@与W@在所有的external声明（谢谢你JeroenWiertPluimers指出了这一点）。

另请注意， StartService和StopService只发送一个启动/停止信号，但不要等待服务处于停止状态的运行状态。 您可以使用IsServiceRunning和Pascal Script Sleep()函数来构造等待服务运行的代码。 或者只是Sleep()预定义的秒数。

代码实现了这些功能：

function IsServiceInstalled(ServiceName: string) : boolean;
function IsServiceRunning(ServiceName: string) : boolean;
function InstallService(FileName, ServiceName, DisplayName, Description : string;ServiceType,StartType :cardinal) : boolean;
function RemoveService(ServiceName: string) : boolean;
function StartService(ServiceName: string) : boolean;
function StopService(ServiceName: string) : boolean;
function SetupService(service, port, comment: string) : boolean;

实际代码：

Answer 2

从Inno Setup 5.5.0开始， CloseApplications和RestartApplications指令现在可用。 这些选项将检测正在使用的文件并使用它们关闭应用程序。

Answer 3

这有两个部分：

1. 如何使用Inno Setup创建的安装程序启动和停止服务，如何创建和删除它们，如何更改其启动模式？

   通过使用为此目的而编写的此例程集合中提供的辅助函数。 它是为Inni Setup的Ansi版本编写的，因此对API函数导入和PChar参数类型进行更改是必要的，但它应该可以帮助您入门。

2. 如何在复制新文件版本之前停止现有服务？

   你基本上有两种方法可以做到这一点。 您可以使用Pascal脚本来执行链接到上面的函数来停止服务，您只需要决定是否在其中一个事件函数中执行它，或者是否在通过Check参数调用的自定义函数中执行它服务可执行文件的文件条目。 我肯定会在前者中执行此操作，因此您可以检查服务是否已成功停止，并禁止安装在此失败时实际启动。

   您应该查看CurStepChanged()和NextButtonClick()事件函数，具体取决于您是否可能需要阻止下一步。 Inno Setup示例显示了这两种功能的使用。

Answer 4

我正在使用停止，卸载，安装和启动给定服务的批处理文件，我只需在复制完所有文件后使用innosetup调用批处理文件。

[Run]
Filename: "{app}\Scripts\installwindowsService.bat"; Parameters: "{app}"; Flags: runhidden

我将以下命令放在我的批处理文件中

net stop MyService

%SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319\installutil.exe /u MyService.exe 

%SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319\installutil.exe  MyService.exe /unattended

net start MyService

它就像一个魅力，非常简单。 可用于首次安装或更新。 希望它能帮到你。
