Tomcat 正在运行，但 8080 端口没有响应

port java linux tomcat

2022-09-03 04:00:44

我已经通过ssh在linux x64机器中安装了sun和tomcat，我没有root权限，所以我在我的家庭目录中安装了两者。jdk 1.6 x64

我设法成功运行了tomcat，但是如果我尝试输入 mydomain.com:8080 服务器没有答案。

使用此命令：

netstat -atnp|grep LISTEN

我检查了端口，它正在收听

任何想法是什么问题？

答案 1

第一步是在本地登录时运行 telnet localhost 8080。然后输入类似的东西

GET /

你应该找回HTML。如果这不起作用，那么tomcat没有真正正常运行或没有在端口8080上侦听。如果这有效，但从外部尝试时，请确保您拥有正确的IP地址。请先尝试使用 IP 地址。如果IP地址有效，也许您的 mydomain.com 无法解析。如果ip是正确的（与您正在使用的ip相同），并且它仍然不起作用，那么您可能正在运行不允许8080通过的防火墙。更改防火墙配置需要根访问权限。

答案 2

对我来说，问题是我的Tomcat开始只听IPv6。把它放在这里，以防其他人发现同样的事情。

我能够得到适当的回应

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

但不是本地主机。为了解决这个问题，我从conf/server中删除了属性.xml：address

<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。我知道它应该是其他方式，但这就是为我解决的问题。OS是Ubuntu。
