This topic describes how to stop and disable FirewallD on RHEL 7.Prerequisites
The firewall on a RHEL 7 system is enabled by default. Before you restart the CLC, you must disable the firewalld service on all host machines.
For more information, see FirewallD on RHEL 7 or FirewallD on CentOS .
To stop and disable FirewallD Check the status of the firewalld service:
systemctl status firewalld.service
The status displays as active (running)
or inactive (dead)
. If the firewall is active / running, enter this command to stop it:
systemctl stop firewalld.service
To completely disable the firewalld service, so it does not reload when you restart the host machine:
systemctl disable firewalld.service
Verify the status of the firewalld service:
systemctl status firewalld.service
The status should display as disabled
and inactive (dead)
.
firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Repeat these steps for all host machines. The firewalld service is stopped and disabled. You can now start the CLC and other host machines.
