I have mentioned that the newly purchased server of the company uses centos 5.5. After deploying tomcat, I found that I entered 114. 80. *. *: 8080 (IP: 8080), but the default Tomcat Homepage cannot be displayed. Because we used to deploy Windows Server VPs and only use localhost for Linux development, it is a little too big. Okay, G. I have a firewall problem on the Internet.
/Etc/init. d/iptables stop After it is disabled, check 114. 80. *. *: 8080 (IP: 8080) again. However, it seems that security risks are greatly increased ...... Use
/Etc/init. d/iptables status View the firewall information and view the opened port. It is feasible to open the port to be used. The command is as follows:
/Sbin/iptables-I input-P TCP -- dport 8080-J accept #8080 specify a port
/Etc/rc. d/init. d/iptables save # Save the changes
/Etc/init. d/iptables restart # Restart the firewall to make the changes take effect. Of course, if you don't feel the trouble, you can restart the system (command: reboot ). /Etc/sysconfig/iptables Add a row:
-A RH-Firewall-1-INPUT-M State-State new-m tcp-p tcp-dport 8080-J accept
Permanently disable the Firewall
Chkconfig-level 35 iptables off # This method is originated from the network and has not been tested. Therefore, you are not allowed to use this method for security reasons.
