linux solution after the start tomcat browser inaccessible
http://www.jb51.net/article/130218.htm
Foreword
Whether you want to start, or to shut down tomcat service, are going to install tomcat bin directory path, of course, if your computer shuts down naturally is not required.
But recently after starting discovered a problem: Centos servers, local and server ip ping each normal (native ping server, ping local), but later deployed tomcat server, the machine can not tomcat through a browser to access the server 8080 port.
For example, the public network server ip is: 123.123.123.123, after starting tomcat default port is 8080, when accessed through 123.123.123.123:8080, tomcat can not access the default page issue to consider is the server firewall.
Confirm turned tomcat
$ Ps -ef | grep tomcat
console output, indicating that already is on tomcat

If tomcat is not on, by the tomcat turned startup.sh command, direct input path to the file.
$ /Usr/local/java/tomcat8/bin/startup.sh
console output:

Tomcat started.
Tomcat started.表明tomcat已开启成功!
Configure the firewall
Edit Firewall Configuration
$ Vi / etc / sysconfig / iptables
add firewall port 8080, allowing access.

Restart the firewall
$ Service iptables restart
after 123.123.123.123:8080 can be accessed through a browser in the machine, you can normally see the default tomcat welcome page.
