This article shows you how to use Tomcat 6 on RHEL5.5 that cannot be accessed from other machines. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Tomcat6 is installed on RHEL5, and after startup, it can be accessed locally, but not from other machines. It turns out that it is the problem with iptables.

1. Environment:

Vmware workstation 7.1.2 build-301548

RedHat Enterprise Linux 5.5

Apache-tomcat-6.0.30

Jdk1.6.0_22

two。 Problem description:

Tomcat6 is installed on RHEL5, and after startup, it can be accessed locally, but not from other machines.

Default ittables rules after 3.RHEL5 installation:

[root@localhost] # iptables-L

Chain INPUT (policy ACCEPT)

Target prot opt source destination

RH-Firewall-1-INPUT all--anywhere anywhere

Chain FORWARD (policy ACCEPT)

Target prot opt source destination

RH-Firewall-1-INPUT all--anywhere anywhere

Chain OUTPUT (policy ACCEPT)

Target prot opt source destination

Chain RH-Firewall-1-INPUT (2 references)

Target prot opt source destination

ACCEPT all-anywhere anywhere

ACCEPT icmp-anywhere anywhere icmp any

ACCEPT esp-anywhere anywhere

ACCEPT ah-anywhere anywhere

ACCEPT udp-- anywhere 224.0.0.251 udp dpt:mdns

ACCEPT udp-anywhere anywhere udp dpt:ipp

ACCEPT tcp-anywhere anywhere tcp dpt:ipp

ACCEPT all-anywhere anywhere state RELATED,ESTABLISHED

ACCEPT tcp-anywhere anywhere state NEW tcp dpt:ssh

REJECT all-anywhere anywhere reject-with icmp-host-prohibited

4. Solution:

Delete the rule on the current INPUT chain

Iptables-F INPUT

Add two INPUT chain rules for ports 80 and 8080 of tcp (8080 is the default port for tomcat)

Iptables-An INPUT-p tcp-s 0ax 0-- dport 80-j ACCEPT

Iptables-An INPUT-p tcp-s 0ax 0-- dport 8080-j ACCEPT
