PRIMECLUSTER Installation and Administration Guide 4.6

I.2.3 Presetting

1. Disabling Firewall

   Check if firewalld is disabled.

   # systemctl status firewalld

   If firewalld is enabled, disable it.

   # systemctl stop firewalld
   # systemctl disable firewalld

2. NTP settings

   Before building the cluster, make sure to set up NTP that synchronizes the time of each node in the cluster system.

   Make these settings on the guest OS before you install PRIMECLUSTER.
