The Perfect Setup - OpenVZ with CentOS 4.4 - Page 2

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

The pictures in step 2 do not match the instructions.

The words say,  Manual partition with Disk Druid.

 The pics say, Automatic with Manual verification.

 Also, the example text for partition layout does not match the resulting view in the partition editor.

 Unless using the automatic partitioning scheme, logical volumes must be created by hand.

 I love these tutorials!! I just thought I would point these things out for future clarity.

Make Sure you download the correct kernel

When you download the kernel, make sure you have the right one. If you have a SMP (or hyperthreading) CPU make sure you download the SMP version of the kernel (ovzkernel-smp) and if you have 4gb of ram or more make sure you get (ovzkernel-entnosplit)

 Utilities

With the newest version of OpenVZ, you should get the utilites aready included on the kernel install. So you may not need to install the utils.

Add DNS

It is best to add a DNS server after you add the ip address to the server:

vzctl set 112 --ipadd 192.168.6.112 --save

Centos Template Cache

Sometimes it is best to download a precompiled version of the Centos-4 template.  Creating your own template can cause problems at times.
