The firewall configuration of CentOS7 is very different from that of the previous version. The firewall of this version of CentOS7 uses firewall by default, which is different from the previous version using iptables.

1. Turn off the firewall:

Systemctl stop firewalld.service

2. Enable the firewall:

Systemctl start firewalld.service

3. Turn it off and start up:

Systemctl disable firewalld.service

4. Turn it on and start:

Systemctl enable firewalld.service

At this point, this is the end of this article on linux to see whether the firewall is off. For more information about how to check whether the firewall is off, please search for previous articles or continue to browse the relevant articles below. I hope you will support it in the future!
