How To Install Docker on CentOS 6
Filed under: Technical Support
Introduction

Docker is a container-based software framework for automating deployment of applications. “Containers” are encapsulated, lightweight, and portable application modules. The major (intended) benefit of using a container is that your application will run consistently on and between any server, be it cloud or dedicated, or of varying operating systems.

Pre-Flight Check
  • As of April 2014 Docker is in development, and the Docker community does not yet consider the software to be production ready. The current version is v0.6.3.
  • These instructions are intended for installing Docker.
  • I’ll be working from a Liquid Web Core Managed CentOS 6.5 server, and I’ll be logged in as root.

Update and Patch OpenSSL for Heartbleed Vulnerability
What is OpenSSL?

OpenSSL is a common cryptographic library which provides encryption, specifically SSL/TLS, for popular applications such as Apache (web), MySQL (database), e-mail, virtual private networks (VPNs), and more.

What is “the Heartbleed Bug”?

The Heartbleed Bug is a severe vulnerability in OpenSSL, known formally as “TLS heartbeat read overrun (CVE-2014-0160)“. As of April 07, 2014, a security advisory was released by OpenSSL.org, along with versions of OpenSSL that fix this vulneratbility.

What are the risks?

In short, the risks are many. In most circumstances, this flaw allows an attacker to read the memory of servers running vulnerable versions of OpenSSL. This would allow attackers to impersonate users and services, and provide a means for data theft. For example, the exposed memory could include sensitive information such as private keys. If private keys are leaked, then it is possible that SSL certificates are compromised, and in that case should definitely be reissued.

What do I do?
  • Update and reboot your server immediately.
  • After the server has been rebooted, change all passwords associated with the server.
  • Consider getting your SSL certificates reissued.
Pre-Flight Check
