为什么TomCat 8无法在我的Ubuntu 15.04系统上工作？

问题描述

我已经使用以下命令在Ubuntu 15.04系统上安装了TomCat 8 ：

sudo apt-get install tomcat8 tomcat8-docs tomcat8-admin tomcat8-examples

因此，我的安装目录为：

/usr/share/tomcat8/bin

因此，我输入此目录，然后执行以下命令来启动服务器：

sudo ./startup.sh

我得到这个：

andrea@andrea-virtual-machine:/usr/share/tomcat8/bin$ sudo ./startup.sh 
Using CATALINA_BASE:   /usr/share/tomcat8
Using CATALINA_HOME:   /usr/share/tomcat8
Using CATALINA_TMPDIR: /usr/share/tomcat8/temp
Using JRE_HOME:        /usr/lib/jvm/java-8-oracle
Using CLASSPATH:       /usr/share/tomcat8/bin/bootstrap.jar:/usr/share/tomcat8/bin/tomcat-juli.jar
Tomcat started.

因此，我认为服务器已启动。

问题是，如果我尝试在浏览器中打开此URL ，则会错误消息： 连接失败 （我不知道这是正确的英语翻译，因为我看到的是意大利语语言）。

如果尝试打开此URL **** **（没有8080端口规范），则会获得Apache 2 Web服务器信息页面（我将其用于某些PHP网站）。

如果我尝试执行TomCat关闭， 则会收到以下错误消息：

andrea@andrea-virtual-machine:/usr/share/tomcat8/bin$ sudo ./shutdown.sh
Using CATALINA_BASE:   /usr/share/tomcat8
Using CATALINA_HOME:   /usr/share/tomcat8
Using CATALINA_TMPDIR: /usr/share/tomcat8/temp

Using CLASSPATH:       /usr/share/tomcat8/bin/bootstrap.jar:/usr/share/tomcat8/bin/tomcat-juli.jar

那么可能是什么问题呢？ 我想念什么？ 我该如何解决？
