CentOS Linux Install OpenVZ Virtualization Software

To install OpenVZ virtualization software on a CentOS Linux system, you will need to add the OpenVZ repository to your system and install the OpenVZ packages.

Here are the steps to install OpenVZ on a CentOS Linux system:

1. Add the OpenVZ repository to your system by creating the /etc/yum.repos.d/openvz.repo file with the following content:

[openvz]
name=OpenVZ
baseurl=http://download.openvz.org/template/precreated
enabled=1
gpgcheck=0

This will add the OpenVZ repository to your system and enable you to install the OpenVZ packages using the yum package manager.

2. Install the OpenVZ packages using the yum package manager:

sudo yum install vzkernel vzctl vzquota

This will install the OpenVZ kernel, control utilities, and quota tools on your system.

3. Edit the /etc/sysctl.conf file and add the following line to enable the OpenVZ kernel:

kernel.sysrq = 1

4. Load the OpenVZ kernel by running the following command:

sudo modprobe vz

5. Add the OpenVZ kernel to the default kernel list by running the following command:

sudo grubby --set-default /boot/vmlinuz-2.6.32-042stab123.7

This will set the OpenVZ kernel as the default kernel on your system.

6. Reboot the system to apply the changes:

sudo reboot

The OpenVZ virtualization software is now installed on your system and ready to use.

It's always a good idea to carefully review the documentation and use the appropriate commands to install and configure OpenVZ on your system. This will help ensure that you have a stable and reliable virtualization platform for your Linux system.
