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.

我在我的安装程序中使用此代码作为#include.它是在Inno Setup ANSI中编译的.
它可能适用于Inno Setup的Unicode版本,A@可以W@在所有external声明中替换(感谢JeroenWiertPluimers指出这一点).

另外请注意,StartService并StopService只发送一个开始/停止信号,但不等待服务是处于停止状态的运行.您可以使用IsServiceRunning与Pascal脚本Sleep()功能结合使用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.它是针对Inno 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,但它应该让您入门.

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,或者是否在将通过Check参数调用的自定义函数中执行此操作.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.
