在Ubuntu 22.04服务器上安装OpenOLAT

Question

我想在我的 Ubuntu 22.04 上安装开源 OpenOLAT，但每次尝试都失败。

有关安装和开源的更多信息和详细信息可以在这里找到：

有人能帮我解决这个问题吗？我已经尝试过各种指示，但没有效果。我不知道这可能是什么原因。

我尝试按照下面提到的手册安装该应用程序： https://www.openolat.com/fileadmin/adminwiki/SW5zdGFsbGF0aW9u.html

    <Engine name="Catalina" defaultHost="localhost">
      <Host name="localhost"  appBase="webapps" />
    </Engine>
  </Service>
</Server>' >> ~/conf/server.xml
Set environment variables:

bash

         username="oodbu" password="oodbpasswd"
         driverClassName="org.postgresql.Driver"
         validationQuery="SELECT 1" 
         validationQueryTimeout="-1" 
         testOnBorrow="true" 
         testOnReturn="false"
         url="jdbc:postgresql://localhost:5432/oodb"/>
</Context>' >> ~/conf/Catalina/localhost/ROOT.xml
Configure log4j2:

bash
Copy code
echo '<?xml version="1.0" encoding="UTF-8"?>

尝试使用此处的官方安装指南进行安装：https://docs.openolat.org/manual_admin/installation/installGuide/

您使用的是过时的安装说明。如果您仍然遇到问题，则必须更加具体。究竟是什么不起作用？您的

catalina.out

或

olag.log

有错误吗？
