Disabling the Firewall

To disable the firewall on each host in your cluster, perform the following steps on each host.

  1. Save the existing iptables rule set.
    • iptables-save > /root/firewall.rules
  2. Disable iptables.
    • For RHEL, CentOS, Oracle, and Debian:
      chkconfig iptables off


      /etc/init.d/iptables stop
    • For SLES:
      chkconfig SuSEfirewall2_setup off


      rcSuSEfirewall2 stop
    • For Ubuntu:
      service ufw stop
