Sakai 11 - 二进制安装成功且其 webapps 已部署，但它们无法启动
Sakai 11 - Binary installation is successful and its webapps deploy, but they fail to start
OS: Windows 10
Java Version: 1.8.0_121-b13
Server Version: Apache Tomcat/8.0.32
我是 Sakai 的新手，我一直在尝试将它作为家庭作业的一部分。起初，我尝试从源代码安装它。不幸的是，它每次都无法在 samigo-services 上构建。所以，我决定按照本指南安装它的二进制文件：https://confluence.sakaiproject.org/pages/viewpage.action?pageId=106792016
Java、Tomcat和Sakai-bin的安装成功。但是当我按 startup.bat 启动服务器时，我开始收到所有这些异常，因为它已经开始从 sakai-bin 中提取 *.war 文件。 Tomcat服务器最终运行正常，但是这些部署的webapps无法启动。

我对这些日志几乎一无所知，但我怀疑这些日志表明了为什么这些已部署的网络应用程序根本无法启动。
如何修复这些错误并使这些 webapps 成功启动？
谢谢。
这些看起来像最近在 sakai-dev thread here. 上讨论的错误解决方案是
- 我下载的 sakai.properties 文件有 UNIX 行结尾。将它们更改为 Windows LF。
- 我错过了将 apache-tomcat-8.0.32 文件夹重命名为 tomcat（不确定为什么需要这样做，因为 %CATALINA_HOME% 指向 [=26 的位置=]
对于 Sakai 11.3，您应该使用 tomcat 8.0.32，对于 Sakai 11.4，您可以使用 tomcat 8.0.43。在 Windows 上进行的测试很少，如果其他所有方法都失败，在 Linux Virtualbox 中安装 Tomcat 和 Sakai 应该可以消除大多数可能的问题。
OS: Windows 10
Java Version: 1.8.0_121-b13
Server Version: Apache Tomcat/8.0.32

我对这些日志几乎一无所知，但我怀疑这些日志表明了为什么这些已部署的网络应用程序根本无法启动。
如何修复这些错误并使这些 webapps 成功启动？
谢谢。
这些看起来像最近在 sakai-dev thread here. 上讨论的错误解决方案是
- 我下载的 sakai.properties 文件有 UNIX 行结尾。将它们更改为 Windows LF。
- 我错过了将 apache-tomcat-8.0.32 文件夹重命名为 tomcat（不确定为什么需要这样做，因为 %CATALINA_HOME% 指向 [=26 的位置=]
对于 Sakai 11.3，您应该使用 tomcat 8.0.32，对于 Sakai 11.4，您可以使用 tomcat 8.0.43。在 Windows 上进行的测试很少，如果其他所有方法都失败，在 Linux Virtualbox 中安装 Tomcat 和 Sakai 应该可以消除大多数可能的问题。
