我确信答案很简单，但是我正在把头发撕掉。 我正在用Apache 2.4和Tomcat 8.5.23在新的Ubuntu 16系统上重buildapache httpd + tomcat站点。 我有tomcat运行和ajp13连接器似乎正在运行，但请求http：//abilities.tld/给404。在mod_jk.log中出现的404源于tomcat，所以它不是一个简单的httpd 404。

访问http://1.1.1.1:8080/host-manager/html工作正常，并显示虚拟主机
catalina日志按预期显示了WAR的启动部署。

我还能在哪里找出为什么tomcat给404的？
谢谢
所以答案是tomcat虚拟主机无法加载，并且web请求由localhost（默认）虚拟主机提供。 因此404。
