About Tomcat:
Tomcat server is a free open source Web application Server, is a lightweight application server, in the small and medium-sized systems and concurrent access users are not many occasions are widely used, is the first choice to develop and debug JSP programs.

Tomcat is actually an extension of the Apache server, but it runs independently of the runtime, so when you run Tomcat, it actually runs as a standalone process with Apache.

If the Java runtime environment is not installed, refer to here:

It is now OK to say that starting Tomcat does not have normal access, we need to open "8080" port;

Enter the command "Firewall-cmd--reload" reload the firewall so that the open 8080-port eloquence takes effect;

Note: If your system is CENTOS6 and the following version, then find the iptables configuration file;
And at the end of the file, add "-A input-m State--state new-m tcp-p TCP--dport 8080-j ACCEPT";
Then type "service iptables restart" to reboot the firewall.
After opening port 8080 in the firewall, you can enter the "IP: Port number" in the browser, as shown in the following figure:
