Get Virtualizor

Master Server


Installing Softaculous Virtualizor Master only server is very simple. Any Virtualizor server (with one or more virtualization) can be set as the master of a cluster. Master only server can be installed on any vps as there is no virtualization technology installed on the server only the Virtualizor panel is installed. There is absolute no necessity to have a Master only server. However some users prefer not to have any virtualization software installed on the master. This guide will show you how to install a Virtualizor Master only server.


  • CentOS 5.x / 6.x / 7 or Red Hat Enterprise Linux 5.x / 6.x or Scientific Linux 5.x / 6.x or Ubuntu 12.04 or Ubuntu 14.04 (x86 or x86_64) or AlmaLinux 8.x
  • Yum

Partition Scheme

Create the following partitions on the Hardware Node:

Please create the / partition as per your requirement. As the OS templates will be stored on it and providing more templates will require more space on / partition.


Open a Shell Terminal (e.g. PuTTY) and SSH to your server. Run the following commands:

wget -N
chmod 0755
./ master=1

The installation will begin immediately. It may seem that the installation has stopped, if your network speed is slow, but please let it continue. You will see something like this :
