java - Tomcat 不会在端口 8080 上响应

Question

Tomcat 正在监听端口 8080，但它无法正确响应 HTTP 请求。 我正在运行更新的 Centos 6.2，并且 Tomcat 是从包 tomcat6 安装的。

Tomcat 正在运行并监听端口 8080。

# ps aux | grep -i tomcat

但是当我连接到端口 8080 时，我收到“外部主机关闭连接”消息:

# telnet localhost 8080
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
GET /
Connection closed by foreign host.           

重要的是要注意它确实连接到端口 8080，但是当在连接流上发送任何内容时连接将关闭:

# netstat -tnp

日志显示没有错误消息:

为了安心，我检查了防火墙:

# iptables -L -vn
Chain INPUT (policy ACCEPT 6042 packets, 1563K bytes)
 pkts bytes target     prot opt in     out     source               destination         

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)
 pkts bytes target     prot opt in     out     source               destination   

我怎样才能做进一步的故障排除!？ 谢谢!

Answer 1

可能是您的 ROOT 上没有部署任何应用程序？

你能发布你的/tomcat/webapps/*的内容吗？

假设您部署了 application.war，所以您宁愿这样做

GET /application/something

我刚刚在我的工作 tomcat 上进行了测试，当调用 GET/ 它也没有返回任何内容，因为那里没有部署应用程序(tomcat 中 root 的默认值为 /tomcat/webapps/ROOT )

希望我能帮上忙。
