How to turn off firewall on CentOS 7?

Important:
Do not turn off firewall in Production and Pre-production servers. Figure out the ports to open for all the technologies that run in the server and open these rules in firewall.

In Developer Box, Developer Instance and QA Instance environments its safe to turn off for quick deployment.

You need to be an administrator to perform these changes.

//check the status of firewall
sudo systemctl status firewalld

//stop the firewall
sudo systemctl stop firewalld

//disable firewall so that it doesn't start again when restarted
sudo systemctl disable firewalld
