我试图在Debian 5和Debian 6上以两种不同的方式（ 从源代码和apt-get ）安装Apache Tomcat 5.5和6 – 没有成功。 服务器正在运行，但无法连接到它。

我也尝试了强制分配Tomcat到我的VPS外部IP。 我也一直在VM初始化期间发生错误无法为对象堆预留足够的空间。 错误不时，但我想这不是问题，因为Tomcat没有反应。
对不起，这么多的文字 – 我试图提供信息。 请帮帮我。 先谢谢你！
更新正如答案中所述，Tomcat正在监听IPv6端口。 为了改变这种情况，我不得不为JAVA机器添加一个环境variables到/etc/profile文件
JAVA_OPTS="-Djava.net.preferIPv4Stack=true" export JAVA_OPTS
…重新加载文件： source /etc/profile
…然后通过以下方式编辑/etc/tomcat5.5/server.xml （在我的情况下）来configurationTomcat的主Connector ：
<Connector port="8080" maxHttpHeaderSize="8192" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" address="0.0.0.0" />
注意address="0.0.0.0"告诉Tomcat绑定到一个IPv4地址。
谢谢你的时间，每个人都有美好的一天。
Tomcat似乎只能侦听IPv6回送地址::1 。
它闻起来像是一个防火墙问题 – 尝试在防火墙中打开相关规则（考虑只是让所有内容进出，我从来没有看到限制回环stream量的合法情况）。
