Tomcat 9.0.8 Http 状态 404

Question

我安装了 tomcat 9.0.8 。我将位置切换到 localhost.server 并将服务器位置更改为使用 tomcat 安装，但我仍然无法打开 tomcat 的主页。我收到 http 状态 404 错误。当我在启动 Web 服务器后在控制台中看到时，我收到以下错误。我也在本地推tomcat v9.0.8服务器遇到了问题。

Answer 1

错误：

java.io.FileNotFoundException: C:\Program Files\Apache Software Foundation\Tomcat 9.0\logs\localhost_access_log.2018-05-30.txt (Access is denied)

清楚地表明这是一个访问问题，很可能是您没有访问文件的权限（很可能是写权限）。

由于您使用的是windows操作系统，如果您不是管理员，可能您必须联系您的管理员为您打开该权限。
