Introduction to The Martian text:

What ' s LXC?

LXC is a userspace interface for the Linux kernel containment features.
Through a powerful API and simple tools, it lets Linux users easily create and manage system or application containers.
Features

Current LXC uses the following kernel features to contain processes:

Kernel Namespaces (IPC, UTS, Mount, PID, network and user)
Apparmor and SELinux Profiles
Seccomp Policies
Chroots (using Pivot_root)
Kernel Capabilities
Control groups (cgroups) # need to use cgroups subsystem

As such, LXC is often considered as something in the middle between a chroot on steroids and a full fledged virtual Machin E. The goal of LXC is to create an environment as close as possible as a standard Linux installation but without the need For a separate kernel.
Components

LXC is currently made of a few separate components:

The LIBLXC Library
Several language bindings for the API:
Python3 (In-tree, long term support in 1.0.x)
Lua (in tree, long term support in 1.0.x)
Go
Ruby
Python2
Haskell
A set of standard tools to control the containers
Container templates

Licensing

LXC is free software, most of the code is released under the terms of the GNU lgplv2.1+ license, some Android compatibilit Y bits is released under a standard 2-clause BSD license and some binaries and templates is shipped under the GNU GPLv2 License.
Where do I get it?
From upstream

You can fetch the latest upstream tarballs this or grab it directly from Git here or with:

git clone git://github.com/lxc/lxc

Actual Combat part:

Preparatory work:

System environment and Yum Source

650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M00/54/28/wKioL1R6jGuh4ipWAAFM4cYtj7o799.jpg "title=" Os_ Yum.png "alt=" Wkiol1r6jguh4ipwaafm4cytj7o799.jpg "/>

To install the required packages:

1) debootstrap

Debootstrap is used to create a Debian base system from scratch, without
Requiring the availability of dpkg or apt.

2) Libvirt

Eliminate the hassle of configuration, directly with this ^_^

3) Libcgroup

Control groups infrastructure. The tools and library help manipulate, control administrate and monitor control groups and the associated controllers.

4) Lxc Lxc-templates

Main package and template (wait for us to change the Yum source of the template file slightly)

5) GCC rsync is of course required

Lxc-create creates a container

Options:
-N,--name=name name for name of the container
-F,--config=file Initial configuration file
-T,--template=t template to use to setup container

Change Password:

# Chroot/var/lib/lxc/centos_1/rootfs passwd

To start a virtual machine:

# lxc-start-d-N centos_1

Options:
-N,--name=name name for name of the container
-D,--daemon daemonize the container

To view the status of a virtual machine:

# lxc-info-n Centos_1

Such a set is ready, if you want to do lbc,hac such experiments, you can clone more to achieve.

LXC provides us with a number of management tools:

Lxc-attach
Lxc-clone # Cloning related
Lxc-destroy # Destroy
Lxc-ls # List Containers existing on the system.

Lxc-stop # XD
Lxc-usernsexec
Lxc-autostart
Lxc-config
Lxc-execute
Lxc-monitor
Lxc-top # Top you know.
Lxc-wait
Lxc-cgroup
Lxc-console
Lxc-freeze
Lxc-snapshot # to a container image
Lxc-unfreeze
Lxc-checkconfig
Lxc-create # Create
Lxc-info # Display Container status information
Lxc-start # Start
Lxc-unshare

Python API:

Python 3K

Import LXC container = Lxc. Container ("P1") container.create ("Ubuntu") Container.start () container.get_ips () Container.stop ()
