即使正在运行,也无法连接到Tomcat

我试图在Debian 5和Debian 6上以2种不同的方式(从源代码使用apt-get)安装Apache Tomcat 5.5和6- 没有成功。服务器正在运行,但是我无法连接到它。

java -version

我还尝试过将Tomcat强制分配给我的VPS外部IP。我也一直在获取VM初始化期间发生错误无法为对象堆保留足够的空间。错误有时,但我想这不是问题,因为Tomcat仍然没有响应。

太抱歉了,我想提供更多信息。请帮我。先感谢您!

更新 如答案中所述,Tomcat正在侦听IPv6端口。为了更改此设置,我必须将JAVA机器的环境变量添加到/etc/profile文件中

JAVA_OPTS="-Djava.net.preferIPv4Stack=true"
export JAVA_OPTS

...重新加载文件: source /etc/profile

...然后Connector通过/etc/tomcat5.5/server.xml以下方式(以我为例)编辑Tomcat的主目录:

<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"它告诉Tomcat绑定到IPv4地址。

谢谢您的时间,祝大家度过愉快的一天。


当您扫描::1而不是本地主机时,端口是否显示为打开状态?

@Shane Madden感谢您的建议,您是对的:nmap -6 ::1 -p 8009 PORT STATE SERVICE 8009/tcp open ajp13。您可以将其发布为答案,以便我接受吗?

Tomcat似乎仅在侦听IPv6环回地址::1

再次感谢您。通过设置解决这个问题$JAVA_OPTS/etc/profile,它的值-Djava.net.preferIPv4Stack=true和配置Tomcat上侦听address="0.0.0.0"

不知道为什么6年前当我接受答案时,我最初还没有提出这个建议:/

闻起来就像是防火墙的问题-尝试在防火墙中打开相关规则(考虑让所有内容进出lo,我从未见过限制回送流量的合法案例)。


谢谢,这对其他有安装Tomcat问题的人可能有用。
