This document is the step-by-step instruction of adding a VPS hosting box into an H-Sphere cluster by means of H-Sphere update script in H-Sphere 2.5 and up.

For H-Sphere under 2.5 or non H-Sphere boxes you need to install VPS server manually.

Important!
These instructions are valid only for H-Sphere 2.5 Patch 4 and up. For lower H-Sphere versions, perform steps described here.

• Step 1. Preparation
• Step 2. Installation
• Step 3. Edit Boot Loader Configuration File
• Step 4. Reboot the Server
• Step 5. Check Kernel Version
• Step 6. VPS Host Configuration
• Step 7. Configure Network Gateways

For more information on VPS, please contact vps@psoft.net.

Step 1. Preparation

See Preparing Server for H-Sphere VPS Installation in a separate document.

Step 2. Installation

Important!
Add a VPS service to a separate physical box reserved only for VPS. We don't recommend to add other services to this box like web, mail etc.

Starting with H-Sphere 2.5 RC 2, a new physcical VPS box is added to H-Sphere cluster within the standard procedure of adding servers and services (first add a physical Unix box via the cp, then add a logical vps server to it, then run the installation script).

Note: This procedure will install the following core VPS related packages on the VPS host server:

• FreeVPS kernel: freevps-1.5-9
• FreeVPS tools: freevps-tools-1.4-9
• H-Sphere VPS: hsphere-vps-1.5-9.noarch

The packages may vary depending upon the operating system. For a full list of VPS related packages installed on VPS box, please refer to VPS Server per supported operating systems in H-Sphere 2.5 RC 2 Package List.

Step 3. Edit Boot Loader Configuration File

Edit this file (/boot/grub/grub.conf, or /etc/lilo.conf) so its default variable is set to take newly installed kernel as the boot image.

Important! Keep the old kernel image settings, so the system can start if anything goes wrong with the new kernel installation.

• grub.conf
  

  default=0
  timeout=10
  splashimage=(hd0,0)/grub/splash.xpm.gz
  title Red Hat Linux (2.4.21-freevps-1.5-9)
    root (hd0,0)
    kernel /vmlinuz-2.4.21-freevps-1.5-9 ro root=/dev/sda5
    initrd /initrd-2.4.21-freevps-1.5-9.img
  title Red Hat Linux (2.4.18-3)
    root (hd0,0)
    kernel /vmlinuz-2.4.18-3 ro root=/dev/sda5
    initrd /initrd-2.4.18-3.img
  

• lilo.conf
  

  prompt
  timeout=50
  default=linux_patched
  boot=/dev/sda
  map=/boot/map
  install=/boot/boot.b
  message=/boot/message
  linear
  
  image=/boot/vmlinuz-2.4.18-3
      label=linux
      initrd=/boot/initrd-2.4.18-3.img
      read-only
      root=/dev/sda5
  
  image=/boot/vmlinuz-2.4.21-freevps-1.5-9 
      label=linux_patched
      initrd=/boot/initrd-2.4.21-freevps-1.5-9.img
      read-only
      root=/dev/sda5
  

Now apply changes to lilo.conf (skip this step if you use grub boot loader):

# lilo

If you correctly edit lilo.conf, the command will list all labels' values as added.

Step 4. Reboot the Server

Run:

# shutdown -r now

Step 5. Check Kernel Version

Run:

# uname -a

If the procedure has been performed correctly, this command will return a line with parameters of the server which must include 1.5-9.

Step 6. VPS Host Configuration

To configure your virtual servers, run the configuration script:

# /hsphere/shared/scripts/vps-configure.pl

With the further steps, you'll perform basic configuration of your virtual servers. See more on VPS host configuration.

Step 7. Configure Network Gateways
