HOW TO DISABLE FIREWALL IN CENTOS
Hello everyone!
Earlier this month we looked at How to disable firewall in Ubuntu 20.04 today we’re going to look at the same task but in com the CentOS(Red Hat) operating system.
CHECK STATUS
On Ubuntu, we use ufw
to interact with this distribution’s firewall service. On CentOS, the Firewall service is called firewalld
.
To interact and obtain information about the service we use systemctl
. In the case to get the firewall status we use the following command: systemctl status firewalld
.
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)

DISABLE
After verifying that the firewall is active, and we want it to be disabled, let’s use the command: systemctl stop firewalld
[root@lostrouter01 ~]# systemctl stop firewalld
[root@lostrouter01 ~]# systemctl status firewalld
