tomcat运行,但8080端口无响应

Question

我已经通过ssh在linux x64机器上安装了sun jdk 1.6 x64和tomcat,我没有root权限所以我在我的家庭目录中安装了两个.

我设法成功运行tomcat,但如果我尝试进入mydomain.com:8080,那么服务器没有答案.

使用此命令:

netstat -atnp|grep LISTEN

我检查了端口,它正在聆听

有什么问题的想法？

在此先感谢,并为我写的可怕英语感到抱歉.

Answer 1

第一步是在本地登录时运行telnet localhost 8080.然后键入类似的内容

GET /

你应该得到HTML.如果这不起作用,那么tomcat实际上并没有正常运行或者没有在端口8080上侦听.如果这样可行但是从外部尝试时,请确保您拥有正确的IP地址.首先尝试使用ip地址.如果IP地址有效,也许您的mydomain.com无法解析它.如果ip是正确的(你正在使用同一个)并且它仍然没有工作,那么你可能正在运行防火墙,它不允许8080通过.更改防火墙配置需要root访问权限

Answer 2

对我来说，问题是我的Tomcat仅开始侦听IPv6。把它放在这里，以防别人发现同样的事情。

我能够得到适当的回应

curl -g -6 "http://[::1]:8080/"

但不适用于localhost。为了解决这个问题，我从conf / server.xml中删除了 address属性：

<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" URIEncoding="UTF-8" />
           address="0.0.0.0" />

并重新启动，并再次绑定到IPv4。我知道应该是相反的方式，但这就是它对我而言所解决的问题。操作系统是Ubuntu。

Answer 3

尝试在Linux终端上使用以下命令列出LISTEN TCP地址和程序名称的端口详细信息

netstat -ltnpa | grep -i --colour LISTEN

此外,您必须检查防火墙是否打开或关闭.(大多数时候可能会打开并且可能阻止了linux中iptables阻止的特定默认tomcat 8080端口)
