How to Set Up and Use LXD on CentOS Linux 7.x Server

To set up and use LXD on a CentOS 7.x server, follow these steps:

1. Install the lxd package:

sudo yum install lxd

2. Initialize LXD:

sudo lxd init

This will prompt you to answer a series of questions about the configuration of LXD. You can accept the default values or customize the configuration as needed.

3. To create a new container, use the lxc launch command. For example, to create a new container based on the CentOS 7 image:

lxc launch images:centos/7 mycontainer

This will create a new container with the name mycontainer based on the CentOS 7 image.

4. To connect to the container, use the lxc exec command. For example:

lxc exec mycontainer bash

This will open a shell prompt inside the mycontainer container.

5. To stop the container, use the lxc stop command:

lxc stop mycontainer

This will stop the mycontainer container.
