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

      and

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

      and

      rcSuSEfirewall2 stop
    • For Ubuntu: 
      service ufw stop
