部署之前先检查下面2个先决条件是否满足

1、安装了 IIS 模块

win7

在 控制面板→程序和功能→打开或关闭Windows功能→勾选Internet 信息服务（Internet Information Services）安装IIS功能

win server

控制面板→程序和功能→打开或关闭Windows功能→添加角色和功能→下一步选择web服务器（IIS）→勾选安装即可

2、安装了 AspNetCoreModule 托管模块

检查 Internet 信息服务(IIS)管理器 服务器的模块里面有没有 托管模块

如果没有点击下面的链接下载安装

这个是netcore2.1版本

https://pan.baidu.com/s/1AUWntFGHlFYqaWa7aNi9YA

安装完之后最好重启一下系统

3、前两个条件都满足之后，就可以部署IIS站点了，跟平时部署站点的唯一区别就是 应用程序池，选择【无托管代码】，其他基本和 .net 一模一样

解决方案的发布就不再描述了

按照上面两步操作之后依然不能正常访问的话

可以配置下 web.config 里的日志输出目录，跟踪日志查找原因

这里有一个坑需要注意一下，就是日志输出的目录默认是 logs 文件夹下面的，但是它又不会自动创建这个logs目录，简直就是sb操作

所以修改下目录为程序当前目录（.\）即可，然后将目录开关（stdoutLogEnabled）设置成 true

参考下面黄色标注的部分

<?xml version="1.0" encoding="utf-8"?>

<configuration>

  <location path="." inheritInChildApplications="false">

    <system.webServer>

      <handlers>

        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />

      </handlers>

      <aspNetCore processPath="dotnet" arguments=".\GeduDistributionApi.dll" stdoutLogEnabled="true" stdoutLogFile=".\" />

    </system.webServer>

  </location>

</configuration>

<!--ProjectGuid: 92985990-0187-402f-a970-e6c36b29150d-->

这个时候如果网站访问成功就会看到目录下有 .log 文件

查看内容，说明网站已经成功启动，并没有报错信息
