OpenVZ VPS Installation

Now i will give about OpenVZ Virtualization and we can make VPS/Virtual Privat Server with it.and this is basics of cloud computing.
Cz we can use OpenVZ for cloud computing. Sow we must prepare to install it :)

we can install OpenVZ on CentOS.And Here Iam use CentOS 6.3 new version.

So this is step By step Give to you about OpenVZ Instalation On CentOS :

Step One :
we Must add the OpenVZ repository to yum :
~ cd /etc/yum.repos.d
~ wget http://download.openvz.org/openvz.repo
~ rpm --import http://download.openvz.org/RPM-GPG-Key-OpenVZ

Step two :
edit openvz.repo :
~ vi openvz.repo

and Disable openvz-kernel-rhel5 then Enable openvz-kernel-rhel6 repositry instead :
code :

[openvz-kernel-rhel6]
name=OpenVZ RHEL6-based kernel
#baseurl=http://download.openvz.org/kernel/branches/rhel6-2.6.32/current/
mirrorlist=http://download.openvz.org/kernel/mirrors-rhel6-2.6.32
enabled=1 => change this
gpgcheck=1
gpgkey=http://download.openvz.org/RPM-GPG-Key-OpenVZ

[openvz-kernel-rhel5]
name=OpenVZ RHEL5-based kernel
#baseurl=http://download.openvz.org/kernel/branches/rhel5-2.6.18/current/
mirrorlist=http://download.openvz.org/kernel/mirrors-rhel5-2.6.18
enabled=0 => change this
gpgcheck=1
gpgkey=http://download.openvz.org/RPM-GPG-Key-OpenVZ

Step three :
Install VZ Kernel :
~ yum install vzkernel
~ yum install vzctl vzqouta

Step Four :
Change the Boot loader for CentOS with OpenVZ Kernel Boot loader.
~ vi /boot/grub/menu.lst

Change the Default Value = 0
code :
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/mapper/vg_server1-lv_root
#          initrd /initrd-[generic-]version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title OpenVZ (2.6.32-042stab057.1)
        root (hd0,0)
        kernel /vmlinuz-2.6.32-042stab057.1 ro root=/dev/mapper/vg_server1-lv_root rd_LVM_LV=vg_server1/lv_root rd_NO_LUKS LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto  KEYBOARDTYPE=pc KEYTABLE=de rd_LVM_LV=vg_server1/lv_swap rd_NO_DM rhgb quiet
        initrd /initramfs-2.6.32-042stab057.1.img
title CentOS (2.6.32-279.el6.x86_64)
        root (hd0,0)
        kernel /vmlinuz-2.6.32-279.el6.x86_64 ro root=/dev/mapper/vg_server1-lv_root rd_LVM_LV=vg_server1/lv_root rd_NO_LUKS LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto  KEYBOARDTYPE=pc KEYTABLE=de rd_LVM_LV=vg_server1/lv_swap rd_NO_DM rhgb quiet
        initrd /initramfs-2.6.32-279.el6.x86_64.img

Step Five :
Edit sysctl.conf
~ vi /etc/sysctl.conf

add this to sysctl.conf
code :
net.ipv4.ip_forward = 1
net.ipv4.conf.default.proxy_arp = 0
net.ipv4.conf.all.rp_filter = 1
kernel.sysrq = 1
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0
net.ipv4.icmp_echo_ignore_broadcasts=1
net.ipv4.conf.default.forwarding=1

Six Step :
avtivate the sysctl rule
~ sysctl -p

Seven Step :
Edit VZ Configuration :
~ vi /etc/vz/vz.conf

Search the "NEIGHBOUR_DEVS" and change = all

code :
NEIGHBOUR_DEVS=all

Eight Step :
Now Disable SelLinux for runing OpenVZ in CentOS :
~ vi /etc/sysconfig/selinux

set the value of sellinux = disable
code :
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

Finally :
~ reboot

If your system reboots without problems, then everything is fine!
then type :
~ uname -r
2.6.32-042stab072.10

Oke This is just "Basic Cloud Computing" and we will give other in another time :).
