Title: How to install and configure OpenVZ On CentOS 6.4 version
Post by: mohitht on January 31, 2014, 06:04:35 pm

Hi All,

OpenVZ is an operating system-level virtualization technology based on the Linux kernel and operating system. OpenVZ allows a physical server to run multiple isolated operating system instances, known as containers, Virtual Private Servers, or Virtual Environments. .

First add OpenVz repository so go to the yum.repos.d

# cd /etc/yum.repos.d

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

rpm --import http://download.openvz.org/RPM-GPG-Key-OpenVZ

edit the openvz.repo and change the rhel5 repo value to "enabled=0"
and set Rhel6 "enabled=1"

Then install

# yum install vzkernel

Then install the OpenVZ tools as follows

# yum install vzctl vzquota

Set the values in # vi /etc/sysctl.conf as below

• 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
  
  After setting the value run
  # sysctl -p
  
  
  Edit the # vi /etc/vz/vz.conf
  File and include
  
  NEIGHBOUR_DEVS=all
  
  we need to set the SElinux value to disabled
  # vi /etc/sysconfig/selinux
  
  
  Finally reboot the system
  
  # reboot
  
  while booting select the kernel
  and check the kernel version by
  
  # uname -r
  
  
  
  
  Try it  :)
  
  
  Thanks for your time  :)
