Inno Setup脚本注册Windows服务后无法启动Node SSR服务求助

在使用Inno Setup脚本安装程序时，需注册Windows服务以启动Node服务器运行Angular SSR构建，但服务创建后显示“暂停”状态，手动启动/暂停时报错。

可正常运行的Node启动命令 #

"C:\Program Files\nodejs\node" "C:\Program Files (x86)\envVarIssue\ecom\angular\server\main.js"

该命令在CMD中运行完全正常，但通过Windows服务启动失败。安装过程中同时部署了Node.msi，服务创建后无法启动，状态始终为暂停。

报错现象 #

• 启动服务时提示“启动Windows服务时出错”
• 服务状态显示为“暂停”

使用的工具 #

通过nssm工具注册Windows服务，以下为完整Inno Setup脚本代码：

排查及解决方法 #

1. 确保Node安装完成后再操作服务
   当前脚本中安装Node.msi后立即启动服务，但msi安装可能未完全完成（如环境变量配置、组件注册）。需在Node安装命令添加waituntilterminated标志：

   Filename: "{sys}\msiexec.exe"; Parameters: "/passive /i ""{app}\{#NODE64}"""; Flags: waituntilterminated;
   

2. 配置服务工作目录
   Node运行Angular SSR时需要在项目根目录执行，否则可能找不到依赖。添加nssm配置命令：

   Filename: "{app}\{#NSSM64}"; Parameters: "set {#MyAppShortName} AppDirectory ""{app}\ecom\angular"""; Flags: runhidden;
   

3. 检查服务运行权限
   默认Local System账户可能缺少文件访问权限，可配置服务使用管理员账户运行：

   Filename: "{app}\{#NSSM64}"; Parameters: "set {#MyAppShortName} ObjectName ""本地管理员账户"" ""账户密码"""; Flags: runhidden;
   

4. 启用日志定位错误
   通过nssm输出服务日志，查看具体启动失败原因：

   Filename: "{app}\{#NSSM64}"; Parameters: "set {#MyAppShortName} AppStdout ""{app}\service_out.log"""; Flags: runhidden;
   Filename: "{app}\{#NSSM64}"; Parameters: "set {#MyAppShortName} AppStderr ""{app}\service_err.log"""; Flags: runhidden;
   

5. 修正卸载顺序
   卸载时需先停止服务再移除，调整[UninstallRun]段顺序：

   Filename: "{app}\{#NSSM64}"; Parameters: "stop {#MyAppShortName}"; Flags: runhidden;
   Filename: "{app}\{#NSSM64}"; Parameters: "remove {#MyAppShortName} confirm"; Flags: runhidden;
