Step #3 – Configuring Grub, Network and Security

Now the boot loader GRUB will be installed. You can leave the default settings unchanged and click on Next:

On to the network settings. The default setting here is to configure the network interfaces with DHCP, but we are installing a server, so static IP addresses are not a bad idea... Click on the Edit button at the top right. In the window that pops up uncheck Configure using DHCP and give your network card a static IP address (in this tutorial I'm using the IP address 192.168.0.100 for demonstration purposes):

Set the hostname manually, e.g. server1.example.com, and enter a gateway (e.g. 192.168.0.1) and up to three DNS servers (e.g. 145.253.2.75, 193.174.32.18, and 194.25.0.60):

SELinux is a security extension of CentOS that should provide extended security. In my opinion you don't need it to configure a secure system, and it usually causes more problems than advantages

Click on Proceed:

Step #4 – Other Settings

Select the default language for the system and add further languages, if necessary:

Choose your time zone:

Give root a password:

Step #5 – Package Selection and Finalizing the system

Now we are to select the package groups. Uncheck packages on the server group. Install a bare OS without any applications

The installer tells you which CDs it will need to install the selected packages:

The installation begins. This will take a few minutes:

Finally, the installation is complete, and you can remove your CD from the computer and reboot it:

Step #6 - Post Installation

yum update -y

shutdown now -r

2. Installing OpenVZ Kernel

Step #7 - Downloading and Installing OpenVZ Kernel

# cd /etc/yum.repos.d

# wget http://download.openvz.org/openvz.repo

# yum install ovzkernel

Step #8 - Configuring the bootloader

In case GRUB is used as the boot loader, it will be configured automatically: lines similar to these will be added to the /boot/grub/grub.conf file:
