Disable FirewallD on RHEL 7

This topic describes how to stop and disable FirewallD on RHEL 7.

Prerequisites
If you have existing firewall rules on your host machines, you must disable the firewall in order to install Eucalyptus. You should re-enable it after installation.
Note: 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
  1. Check the status of the firewalld service:
    systemctl status firewalld.service
    The status displays as active (running) or inactive (dead).
  2. If the firewall is active / running, enter this command to stop it:
    systemctl stop firewalld.service
  3. To completely disable the firewalld service, so it does not reload when you restart the host machine:
    systemctl disable firewalld.service
  4. 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)
  5. Repeat these steps for all host machines.

The firewalld service is stopped and disabled. You can now start the CLC and other host machines.
