Stackify Prefix http://localhost:2012 拒绝连接

Question

几天前我安装了 Stackify Prefix 3.0.28.0，并且分析器工作正常，直到我重新启动系统。系统重新启动后，当我尝试打开 http://localhost:2012 时，它返回标准 chrome 错误 localhost 拒绝连接。 (ERR_CONNECTION_REFUSED) 但是，正如https://docs.stackify.com/docs/prefix-basic-troubleshooting#verify-if-the-stackify-profiler-is-working 的故障排除指南中所述，我注意到分析器正在收集数据，只有http://localhost:2012 不起作用。

我尝试了故障排除指南中提到的所有选项，包括重新启动系统、IIS、Stackify Prefix Windows Service，并验证了系统环境变量。我还尝试用 127:0.0.1 替换 localhost，为端口 2012 设置 Windows 防火墙规则。一切似乎都很好，但无法让 http://localhost:2012 工作。

http://localhost 和 asp.net 应用程序工作正常。根据 stackify.log 我收到以下错误（即使日志通知 Web 服务器，命名管道服务器已启动）：

Answer 1

我遇到了同样的问题，但在我的情况下，Stackify Prefix Windows 服务已停止，所以我只需要重新启动它。

Answer 2

我在试用 Stackify Prefix 时遇到了同样的问题。我尝试重新安装几次，但在尝试访问 http://localhost:2012 url 时仍然出现相同的“localhost 拒绝连接”错误。重新启动我的机器没有帮助。

我注意到在重新安装期间它一直在尝试安装 vcredist c++ 2013 x64/x32 软件包，但会失败并跳过此步骤。我进入添加/删除程序，发现我之前已经安装了一些 2013 vcredist 软件包。然后我卸载了所有这些包，然后以管理员权限再次运行 Stackify Prefix 安装程序。这次它成功安装了它需要的单个 vcredist x64 包，然后在它成功打开 Prefix Browser url 之后立即。

Tldr;这个问题是由我的机器上已经存在的 vcredist c++ 2013 包引起的 - 卸载并使用 Stackify Prefix 安装程序来安装它们为我解决了这个问题。

Answer 3

将默认端口从 2012 更改为服务器/开发工作站上的开放端口。

1. 以管理员权限打开 CMD.exe。
2. 运行此命令 netstat -anob > c:\test.txt
3. 找到一个监听端口，如下所示： TCP 0.0.0.0:13 0.0.0.0:0 监听 5240
4. 转到您的 Stackify 安装文件夹并打开 stackify.ini 文件。像这样的 C:\Program Files (x86)\StackifyPrefix\stackify.ini
5. 停止 Stackify 服务 StackifyPrefix
6. 将 stackify.ini 中的端口更改为您选择的开放端口。 [设置]正下方 像这样： [设置]
   端口=5240
7. 保存 stackify.ini 文件
8. 启动StackifyPrefix服务
