在IIS7上部署时，log4net不会创建日志文件 [英] log4net doesn't create log file when deployed on IIS7

问题描述

大家早上好，

我有一个log4net问题，当我在我的
本地机器上进行开发时，该问题并不存在，但是一旦我部署了应用程序到服务器，log4net停止工作。

I have a log4net issue that didn't exist when I was developing on my local machine, but once I deployed the application to a server, log4net stopped working.

这是服务器配置：
-Windows XP SP3
-IIS 7
- framework .Net v4

This is the server configuration : -Windows XP SP3 -IIS 7 -framework .Net v4

这是网站web.config中的log4net配置：

This is the log4net configuration in the web.config of the website:

<configuration>
      <log4net>
        <root>
          <level value="DEBUG" />
          <appender-ref ref="LogFileAppender" />
        </root>
        <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
          <param name="File" value="log.txt" />
          <param name="AppendToFile" value="true" />
          <rollingStyle value="Size" />
          <maxSizeRollBackups value="10" />
          <maximumFileSize value="30MB" />
          <staticLogFileName value="false" />
          <layout type="log4net.Layout.PatternLayout">
            <param name="ConversionPattern" value="%-5p%d{yyyy-MM-dd hh:mm:ss} – %m%n" />
          </layout>
        </appender>
      </log4net>
    </configuration>

我还有一个类库，这是它的App.config文件：

I also have a class library and this is its App.config file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
  </configSections>
  <log4net>
    <root>
      <level value="DEBUG" />
      <appender-ref ref="LogFileAppender" />
    </root>
    <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender" >
      <param name="File" value="log.txt" />
      <param name="AppendToFile" value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="30MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%-5p%d{yyyy-MM-dd hh:mm:ss} – %m%n" />
      </layout>
    </appender>
  </log4net>
</configuration>

这是我在每个班级调用日志功能的方式：

This is how I call the log function on every class:

private static readonly ILog log = LogManager.GetLogger(typeof(AppDomain));

...这就是我所说的：

...and this is how i call it :

log.Error("\n\t=>" + ex.GetBaseException().Message + "\n\r" + " @ " + Environment.StackTrace);

推荐答案

可能是你没有权限写到文件'log.txt'。

It could be that you do not have permissions to write to the file 'log.txt'.

我不知道当前目录是什么，但它不太可能是IIS可以写入的地方。

I don't know what the current directory would be but it's unlikely to be somewhere IIS can write to.

您需要在某处创建一个文件夹并授予IIS写入权限，我知道您需要授予对IIS_IUSRS组的访问权限，然后指定该文件的绝对路径。例如。

You need to create a folder somewhere and grant access for IIS to write to it, I understand you need to grant access to the IIS_IUSRS group and then specify the absolute path to that file. e.g.

<param name="File" value="D:\Logs\log.txt" />

..使用您首选位置的路径。

..using the path to your preferred location.
