Tomcat cannot be accessed normally after startup

Today, I helped locate a Tomcat problem. The cat never came out. Maybe the cat caught the mouse.

1. Tomcat starts normally, but cannot be accessed all the time. The customer machine is CentOS,

1) iptables-L-n: Check the list of opened ports. No port is available.

2) Add vi/etc/sysconfig/iptables,

-A RH-Firewall-1-INPUT-m state-state NEW-m tcp-p tcp-dport 5080-j ACCEPT

3) under service iptables restart

The cat caught the mouse.
