VPS Host Installation

This document is the step-by-step instruction of adding a VPS hosting box into an H-Sphere cluster.

Step 1. Prepare Server for H-Sphere VPS Installation

Please refer to a separate doc.

Step 2. Installation

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-1.5-6rc3
• FreeVPS tools: freevps-tools-1.4-3rc1
• H-Sphere VPS: hsphere-vps-1.4-4.noarch

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-1.5-6rc3)
    root (hd0,0)
    kernel /vmlinuz-2.4.21-freevps-1.5-6rc3 ro root=/dev/sda5
    initrd /initrd-2.4.21-freevps-1.5-6rc3.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-1.5-6rc3    label=linux_patched
      initrd=/boot/initrd-2.4.21-freevps-1.5-6rc3.img
      read-only
      root=/dev/sda5
  

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

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:

If the procedure has been performed correctly, this command will return a line with parameters of the server which must include 1.5-6rc3.

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.

Step 7. Configure Network Gateways
