Tomcat won't respond on port 8080
提问by tessiof
Tomcat is listening on port 8080, but it do not respond correctly to HTTP requests. I'm running an updated Centos 6.2, and Tomcat is installed from the package tomcat6.

But when I connect to port 8080, I get a "Connection closed by foreign host" message:
但是当我连接到端口 8080 时，我收到一条“连接被外部主机关闭”消息：

Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...

It's important to note that it do connect to port 8080, but the connection is closed when anything is sent on the connection stream:
需要注意的是，它确实连接到端口 8080，但是当在连接流上发送任何内容时，连接将关闭：

For the peace of mind, I checked the firewall:
为了安心，我检查了防火墙：
# iptables -L -vn
Chain INPUT (policy ACCEPT 6042 packets, 1563K bytes)

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
Chain OUTPUT (policy ACCEPT 4122 packets, 587K bytes)

How can I do any further troubleshooting!? Thanks!
我该如何进行进一步的故障排除！？谢谢！

It could be that you don't have any application deployed on your ROOT?
可能是您的 ROOT 上没有部署任何应用程序？
can you post the content of your /tomcat/webapps/*?
你可以发布你的内容/tomcat/webapps/*吗？
say you have application.wardeployed so you'd rather do
说你已经application.war部署，所以你宁愿这样做
GET /application/something
I just tested on my working tomcat and when calling GET /it also returns nothing because there is no application deployed over there (default for root in tomcat is /tomcat/webapps/ROOT)
我刚刚在我的工作 tomcat 上进行了测试，在调用GET /它时也没有返回任何内容，因为那里没有部署应用程序（tomcat 中的 root 的默认值为/tomcat/webapps/ROOT）
Hope I could help.
希望我能帮上忙。
