Installing Softaculous Virtualizor is very simple.


  • CentOS 5.x / 6.x or Red Hat Enterprise Linux 5.x / 6.x or Scientific Linux 5.x / 6.x (x86 or x86_64)
  • Yum

Partition Scheme

Create the following partitions on the Hardware Node:

Partition Size Description
/ 20 GB + Root partition containing all Hardware Node operating system files
SWAP 2 times RAM Paging partition for the Linux operating system
/vz all the remaining space on the hard disk Partition to host OpenVZ templates and Virtual Private Servers


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

wget -N
chmod 0755

Please give the email address correctly !

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 :


After the installation is completed you will be asked to reboot.


You can then visit the Admin Panel to create Virtual Servers and also manage your server.

Note : A log file of the installation process will be created - /root/virtualizor.log


To login to the Softaculous Virtualizor Admin Panel, visit the following URL :



Login with the servers root details.


Admin Panel

After you login, you will see the Admin Panel Dashboard :



Virtualizor uses ports from 4081 - 4085. If there is any firewall restricting this, you will need to allow these ports.

Trouble Shoot

NOTE : In all cases please remember to disable SElinux

Cant open http://IP-Address:4084

Please check if your iptables firewall is running You can disable it with the following command :

root> service iptables stop

VPS Doesnt start

Please check that the correct kernel has been booted.

root> uname -a

ALSO check that quota is disabled in Linux and OpenVZ has its own Quota management system and it will conflict if the OS's quota is enabled.

root> quotaoff -vaug

Cannot SSH to VPS

The IP must not be added to the Server. You can check if the IP is on the server with the following command :

root> ifconfig

If the IP is there e.g. in eth0:x you will have to remove it. To remove it :

root> rm -rf /etc/sysconfig/network-scripts/ifcfg-eth0:*
root> service network restart

You shall now be able to SSH to your new VPS.
